“…Until very recently, very few Oxyporus species have been barcoded. The only publication that both extensively used barcoding and provided illustrations of the endophallus for a new species is Lee et al (2020 ). It is a very progressive and useful study of the Korean fauna which, unfortunately, was performed with coloration-based taxonomy of Oxyporus in Japan because the authors did not check all their Korean species on their possible conspecifity with Japanese congeners (for details see below).…”

“…Of them, 45 specimens were 96% ethanol-preserved Oxyporus collected by at and as in the Czech Republic and in Russia (table 1). Barcodes for other 30 specimens were taken from the recently published paper on Korean Oxyporus (Lee et al, 2020). A single CO1 sequence of O.…”

“…(O.) maxillosus used by Lee et al (2020) in their analysis, when checked by us via the BLASTn algorithm, turned out to have 100% similarity with the barcode of Microcara testacea Linnaeus, 1767 (Scirtidae) and thus is not included in our research. Six additional specimens from the cnc were sequenced separately (see below) and uploaded to bold Systems (table 1).…”

“…To test the robustness of the dna barcode-based trees, we conducted a total-evidence analysis with a morphological partition (for details see 2.7) and explored the reliability of particular morphological traits as species-specific characters (for details see 2.8). The set of specimens coded in the morphological matrix is the same as for the dna extraction, except for sequences provided by Lee et al (2020) and those downloaded from ncbi. Moreover, there are no specimens included in the matrix without having a barcode.…”

“…Diagnosis. Pronotum smooth or at most with slight impression according to Lee et al (2020;as O. parvus), paratergites of first three or four visible abdominal segments yellow while respective tergites and sternites black. Endophallus: distal lobe bent dorsad, consisting of dorsal, ventral and additional pair of thin bow-like spicules and central sclerite of characteristic shape (fig.…”

DNA-barcode and endophallus morphology delimit congruent species in a systematic revision of the oxyporine rove beetles of Russia (Coleoptera: Staphylinidae: Oxyporinae)

Rigorous species delimitation is a challenge in biology and systematics in particular. In insects, male genitalia traditionally, and the barcoding region of the CO1 gene recently, are the main markers to identify species, even though a standalone use of CO1 for that is often criticized. In our systematic revision of the mycophagous and in other ways peculiar oxyporine rove beetles of Russia, the legacy alpha-taxonomy could not be improved by traditional investigation of genitalia as they are unusually character-poor in this group. Using phylogenetic inference and ancestral state reconstruction, we demonstrate that CO1 and endophallus are useful markers for species delimitation in Oxyporus. We also show that many morphological traits previously used for species delimitation in Oxyporus are in fact highly variable and thus inconsistent. We hypothesize that in Oxyporus diversification of the endophallic structures is driven by intense intra- and inter-species interactions of multiple individuals co-occurring in narrow spaces inside fungal bodies during mating. Our results encourage broader use of both markers, especially easy-to-generate dna barcodes, for the desired alpha-taxonomical work in Oxyporinae globally. The revision revealed 10 species of Oxyporus in the fauna of the Russian Federation; eliminated erroneous species records; established two new synonyms, Oxyporus (Oxyporus) basicornis Cameron, 1930 = O. (O.) aequicollis Bernhauer, 1935, syn.nov. = O. (O.) parvus Lee et al., 2020, syn. nov.; and raised the hypothesis that O. (O.) aokii Dvořák, 1956, O. (O.) basiventris Jarrige, 1948 and O. (O.) kobayashii Hayashi, 2015 are conspecific with O. (O.) maxillosus Fabricius, 1793. Lectotypes are designated for O. (O.) basicornis Cameron, 1930, O. (O.) germanus Sharp, 1889, O. (O.) niger Sharp, 1889, and O. (O.) triangulus Sharp, 1889. Comprehensive taxonomic treatment and an identification key are provided for all species.
