Abstract

:
Osphya Illiger (Melandryidae: Osphyinae) as a species-poor insect group, exhibits a widespread distribution in the Northern Hemisphere, however, the research of the genus is poorly documented especially in East Asia. Herein, an interesting species is discovered in Shennongjia National Natural Reserve (Hubei, China). The examination of morphological characters and comparisons with others show it to be a new member of Osphya, which is described under the name of O. sinensis sp. n. The characteristic photos and a key to the species of Osphya from East Asia are provided. Meanwhile, the mitochondrial genome of O. sinensis sp. n. is sequenced and annotated. Based on this obtained mitogenome and the publicly available data, we reconstructed the phylogeny of Tenebrionoidea by different cladistics methods to investigate the relationships between the new species with others. The results consistently recover O. sinensis sp. n. sister to O. bipunctata (Fabricius) with high supporting values, which further confirm the placement of the new species in the genus Osphya. This is the first time reporting the genus Osphya, the only representative genus of melandryid Osphyinae from mainland China, which enriches the diversity of beetles from the Chinese fauna at both generic and subfamilial levels.

1. Introduction

The genus Osphya Illiger, 1807 belongs to the subfamily Osphyinae of the family Melandryidae in the superfamily Tenebrionoidea [1,2]. To date, it contains 27 species, which are strictly confined in the Northern Hemisphere and widely distributed in Palaearctic (17 species), Nearctic (3 species), Neotropical (3 species), and Oriental regions (4 species) [3,4]. The taxonomy of Osphya has been neglected almost for a century, except for a few species from Europe reported in recent years [3,4]. Most species remain poorly known at present, and except for the simple original descriptions [5,6,7,8,9,10,11,12,13,14,15,16,17], no subsequent data were added even for the distribution records. Although the Chinese mainland has a large area and is recognized as one of the global biodiversity hotspots [18], no Osphya species were recorded in this area except for two species from Taiwan Island (O. trilineata Pic, 1910 and O. formosana Pic, 1927). The absence of Osphya species in the Chinese mainland is bewildering despite the hard work endeavored by Chinese entomologists for many years. Herein, interesting material from Shennongjia National Natural Reserve, Hubei Province, China, was obtained. Its morphological characters seemed to match the diagnosis of Osphya. The genus is characterized by the abruptly narrowed head, latero-basal impressions on pronotum, tarsal formula 5-5-4, bidentate tarsal claws, penultimate tarsomeres with distinct lobes, extended under last tarsomeres, and elongated fist hind tarsomeres, as well as the structure of the aedeagus [3,4,19,20]. Further comparison with others (O. orientalis (Lewis, 1895), O. albofasciata Champion, 1916, O. melina Champion, 1916, O. nilgrica Champion, 1916, O. nigriventris Champion, 1920, O. nigroapicalis Pic, 1921, O. dissimilis Champion, 1922, O. harmandi Pic, 1926, O. rufa Pic, 1927, and O. superba Pic, 1927) from the adjacent areas showed it as an unknown species of Osphya, which will be described herein.
Meanwhile, we successfully sequenced and annotated the mitochondrial genome of the new species. The mitochondrial genome has become a powerful tool for metazoan phylogenetic and evolutionary analysis [21,22,23,24] because of its small size, the presence of high copy numbers, strict orthologous genes, rare recombination, and high evolutionary rate [22,25,26]. It has been applied in many insect groups to solve their phylogenetic relationships, including the whole Coleoptera [27,28,29] and some special groups (e.g., [30,31]), but not exclusively for Tenebrionoidea until now. With the newly sequenced mitochondrial genome and other available data in the public database (NCBI), we are going to investigate the phylogenetic relationship between the new species with others of Tenebrionoidea. Fortunately, the mitochondrial genome of O. bipunctata (Fabricius, 1775) (Melandryidae: Osphyinae) is available as a single sequence of the genus Osphya documented in NCBI, which makes it possible to test whether the new species can be grouped with the latter species into a monophyletic clade or not, thereby confirming the phylogenetic position of the new species.
China, covering a vast geographical area with diverse landscapes and located in a transitional zone between Palaearctic and Oriental regions, harbors giant biodiversity resources [32]. Although dozens of thousands of beetles have been recorded there, there is little doubt that some taxa remain to be discovered. As evidenced by a cursory look at most modern revisionary work, the number of “known” species is only a small subset of the number of “existing” species. This problem is aggravated by the biodiversity crisis and accelerating rates of biological extinction [33]. The global decline of insects and their abundance is becoming drastic due to climate change and human-derived perturbations [34], and it is probable that many species are vanishing without ever having been collected. Therefore, inventory work and targeted collecting (with specimens suitable for both morphological and molecular work) remain essential, and thus a priority, for the future of systematic studies. In this study, we discover and report a new species of Osphya based on both morphological and molecular evidence, which will make this widespread but species-poor genus better known, enrich the species diversity of beetles in the Chinese fauna in both generic and subfamilial levels, and will also increase interest in the other relevant research of enigmatic insects.

2. Materials and Methods

2.1. Materials

The studied material was collected from Shennongjia National Natural Reserve, Hubei Province, China. The type specimens (holotype and three paratypes) of the new species were deposited in the Museum of Hebei University, Baoding, China (MHBU). An additional specimen was fixed directly in 100% ethanol after collection and stored at −20 °C for molecular study.

2.2. Photography and Terminology

The specimens were dissected under the Nikon SMZ1500 microscope. The abdomen and aedeagus of the holotype were mounted on the same board as the body. The photography was processed by a Leica M205A stereomicroscope, and multiple layers were stacked using Combine ZM (Helicon Focus 5.3). The terminology in the species description follows Konvička [3,4]. The distribution information of the species was collected from the original publications and the material studied herein (Table S1). The distribution map was prepared by ArcGIS 10.6 and edited in Adobe Photoshop 2020.

2.3. DNA Extraction, PCR, and Sequencing

Total genomic DNAs were extracted using a DNeasy Blood & Tissue kit (QIAGEN, Beijing, China), according to the manufacturer’s instructions. DNAs were stored at −20 °C for long-term storage and further molecular analyses and deposited at Hebei University (voucher number CAN0214).
Whole mitochondrial genome sequencing was performed using an Illumina Novaseq 6000 platform (Illumina, Alameda, CA, USA) with 150 bp paired-end reads at BerryGenomics, Beijing, China. The sequence reads were first filtered following Zhou et al. [35] and then assembled using IDBA-UD [36] under a similarity threshold of 98% and k values of a minimum of 40 and a maximum of 160 bp. The gene cox1 was amplified by polymerase chain reaction (PCR) using universal primers “5′-GGTCAACAAATCATA AAGATATTGG-3′ (LCO)” and “5′-TAAACTTCAGGGTGACCAAAAAATCA-3′ (HCO)” as “reference sequences” to acquire the best fit. The PCR cycling conditions comprised a predenaturation at 94 °C for 5 min and 35 cycles of denaturation at 94 °C for 50 s, annealing at 48 °C for 45 s, and elongation at 72 °C for 8 min at the end of all cycles. Geneious 2019.2 software [37] was used to manually map the clean readings on the obtained mitochondrial scaffolds to check the accuracy of the assembly. Gene annotation was performed by Geneious 2019.2 software [37] and MITOS Web Server (http://mitos.bioinf.uni-leipzig.de/index.py, accessed on 15 November 2021) [38]. The sequence generated in this study was deposited in GenBank with accession number (MW556727).

2.4. Phylogenetic Analyses

Mitochondrial genomes of 41 species from 16 different families of Tenebrionoidea were selected as ingroups, and those of 2 Cucujoidea species were chosen as outgroups (Table 1). All mitochondrial genomes (except the one sequenced in this study) were obtained from GenBank (accession numbers given in Table 1).
Data standardization and information extraction were performed by PhyloSuite v 1.2.2 [52]. The nucleotide sequences of the 13 protein-coding genes were analyzed. The protein-coding genes were aligned using the MAFFT v 7.313 plugins [53] and optimized using MACES in PhyloSuite v 1.2.2 [52]. Intergenic gaps and ambiguous sites were removed using Gblocks v 0.91b [54], then all protein-coding genes were concatenated in PhyloSuitev 1.2.2 [52]. The optimal partition schemes and the best-fit replacement models were selected by Model Finder [55], and the results are presented in Supplementary Tables S2 and S3. The “greedy” algorithm with branch lengths estimated as “linked” and the Bayesian information criterion were used.
Phylogenetic trees were constructed based on both maximum likelihood (ML) and Bayesian inference (BI). The ML phylogenies were inferred using IQ-TREE.v.1.6.8 [56] and BI phylogenies using MrBayes 3.2.6 [57], respectively. The ML phylogenetic analyses were performed with the ultrafast bootstrap (UFboot) algorithm with 1000 replicates. In BI phylogenetic analyses, 5 × 106 Markov chain Monte Carlo (MCMC) generations after reaching stationarity (average standard deviation of split frequencies <0.01) were used as the default settings, with estimated sample size >200 and potential scale reduction factor ≈ 1 [57]. Interactive Tree of Life (iTOL, http://itol.embl.de) was used to display, annotate, and manage the phylogenetic tree.

Female (Figure 1B). Body more robust and broader than males. Coloration is similar to that of males, but the pronotum, meso- and metasterna, and abdomen are uniformly orange, femora mostly orange and only darkened along the dorsal sides. Antennae shorter, extending to the basal third length of elytra. Pronotum wider, 1.35 times as wide as long. Tibiae straight and femora normal, not inflated. Abdominal ventrite V (Figure 2D) shallowly and triangularly emarginated in the middle of the posterior margin, tergite V (Figure 2H) tapered apically.
Variation within type series. Body length 9.5–10 mm, width 1.9–2.5 mm.
Distribution. China, Hubei Province, Shennongjia National Natural Reserve.
Remarks. The additional material used for the molecular study was seriously damaged in the experiment, so it was not designated as the type specimen.

3.2. Phylogenetic Analyses

In both BI and ML analyses (Figure 4 and Figure S1), the monophyly of Tenebrionoidea is well supported with high supporting values (BS = 100, PP = 1). Additionally, the monophylies of the related families, including Tenebrionidae, Meloidae, Oedemeridae, Anthicidae, Scraptiidae, Salpingidae, and Mordellidae, which with two or more analyzed species are all highly supported (BS = 100, PP = 1). This suggests that the phylogenetic relationships of Tenebrionoidea are generally reconstructed well enough based on the mitochondrial genome data, which can be relied on to investigate the placement of the new species.
Osphya sinensis sp. n. is consistently grouped with O. bipunctata (Fabricius, 1775) into a monophyletic clade, which is strongly supported (BS = 100, PP = 1). These two representative species of Osphyinae were recovered sister to Scraptiidae with high supporting values (BS = 100, PP = 1), instead of Melandryinae (represented by M. gracilis), which is either grouped with Tetratomidae (T. fungorum) by BI analysis (Figure 4) or in an unclear relationship with other lower Tenebrionoidea by ML analysis (Figure S1). This indicates that Melandryidae, with two component subfamilies (Osphyinae and Melandryinae) separate in different clades, is a paraphyly based on the mitochondrial genome-based phylogeny.

4. Discussion

4.1. Separate Status of the New Species

Prior to this study, a total of 12 Osphya species were hitherto known and distributed in the Oriental and eastern and southern Palaearctic regions [1,3] (Figure 5 and Table S1). Among these species, five species are distributed in N India (O. albofasciata Champion [7], O. harmandi Pic [13], O. dissimilis Champion [9], O. nigriventris Champion [8], and O. nigroapicalis Pic [11]), two in Taiwan Island (O. trilineata Pic [10] and O. formosana Pic [14]) and N Vietnam (O. rufa Pic [15] and O. superba Pic [15]), one in Japan (O. orientalis (Lewis) [5]), S Myanmar (O. melina Champion [7]) and S India (O. nilgrica Champion [7]), respectively.
In contrast with the European species [3,4,17], these species are quite poorly known. According to their original descriptions [5,7,8,9,10,11,13,14,15], the new species, O. sinensis sp. n., could be easily differentiated from the above species by the following key.

4.2. Phylogenetic Position of the New Species

The new species, O. sinensis sp. n., matching the diagnosis of Osphya in morphology well, is consistently grouped with O. bipunctata to form a monophyletic clade based on the mitophylogeny of Tenebrionoidea, which is solidly and highly supported. Although Osphya is discovered in the Chinese mainland for the first time, its occurrence is in accordance with the geographical distribution of this genus, which partly occurs in the Palaearctic and Oriental regions [20] covering the Chinese fauna. What is noted, the locality of the new species in mainland China fills the geographical gap of Osphya between the western and easternmost parts of the Palaearctic Region. As a widely distributed genus in the Northern Hemisphere [20], it would be more interesting to investigate the formation of spatial distribution patterns of Osphya, which are highly relevant to the contemporary environment and historical factors, but this is not within the scope of this study.
Further, the phylogenetic analysis of Tenebrionoidea of mitogenomic data showed that the monophyly of Melandryidae is not recovered, which is in agreement with some specialists (e.g., [19]), is also congruent with the results of other molecular phylogenetic studies [28,58], but is discordant with the opinions of the modern coleopterists [1,2,20,59,60]. This probably resulted from a lack of a satisfactory definition for the family, which allows many non-melandryids to be placed in this group [59,60,61,62]. Crowson [59] stated that both the imaginal and larval characterizations of this family were unsatisfactory, so there had been historically wide disagreements over its constitution. In the classification of Pollock [19], only the two subfamilies, Melandryinae and Osphyinae, were recognized, which is a much more restricted concept of the family Melandryidae than that presented by Csiki [61], Crowson [59], Arnett [62], and Lawrence and Newton [60]. This classification was adopted in the latest catalog of Palearctic Coleoptera by Nikitsky and Pollock [20]. The Osphyinae can be distinguished from Melandryinae in the characteristics of both adults and larvae [1], which can be considered as synapomorphies of each lineage.
However, Osphyinae is recovered sister to Scraptiidae, congruent with the results of other molecular phylogenetic results, such as Hunt et al. [58], Gunter et al. [63], and Timmermans et al. [28]. Additionally, Melandryinae seems more related to Tetratomidae, which is consistent with the result of Hunt et al. [58]. Crowson [59] suggested that Melandryidae be close to Tetratomidae due to some affinities in adult structures also shared with Scraptiidae, Mordellidae, and Ripiphoridae, but their similarities were argued to be convergent by Lawrence [64]. Thus, a more comprehensive systematic study of Melandryidae is needed to verify their relationships to other lower Tenebrionoidea, suggested by Pollock [19].

5. Conclusions

The genus Osphya is discovered in the Chinese mainland for the first time, with a new species, O. sinensis sp. n., reported from Shennongjia National Natural Reserve, Hubei Province. Among the Osphya species that are distributed in China and adjacent countries or areas, the new species is most similar to O. superba located in N Vietnam but definitely differs from the latter species in the body size and coloration. Except for the morphological evidence, the placement of the new species in the genus Osphya is further confirmed by the mitophylogenetic analyses of Tenebrionoidea, and a sister relationship is recovered between the new species and O. bipunctata. However, its phylogenetic position in Melandryidae remains uncertain due to the paraphylum of the family, with the two component subfamilies Osphyinae and Melandryinae separate in different clades. Nevertheless, the new species is definitely attributed to Osphya of Osphyinae, but larger scale studies with more locus and taxon sampling are still needed to reconstruct more comprehensive phylogenies in order to achieve a better resolution of the relationships of Osphyinae to Melandryinae and other families of Tenebrionoidea.
