Stenaptinus (Coleoptera: Carabidae: Brachininae) of Vietnam. Note 2

Abstract

The bidoupensis-group and dissolutus-group of the the genus Stenaptinus Maindron, 1906 (Brachinini, Brachininae, Carabidae) have been reviewed just recently [Fedorenko, 2020]. In this paper we review the species of the javanus species group from Vietnam, describe two new species and one new subspecies and revise some others based chiefly on comparative analysis of male and female genitalia. Acronyms used are as follows: EASC — East Asia Terrestrial Biodiversity Scientific Center, Vladivostok; MNHN — Museum National d’Histoire Naturelle, Paris; MSPU — the Moscow State Pedagocical University; SIEE — the author’s reference collection at A.N. Severtsov Institute of Ecology & Evolution, Russian Academy of Sciences, Moscow; ZISP — Zoological Institute, Russian Academy of Sciences, St. Petersburg; ZMMU — Zoological Museum of the Moscow State University; ZSM — Siberian Zoological Museum, Novosibirsk. The following parameters and ratios (Table) were analyzed: maximum body length measured between apices of closed mandibles and sutural angle of elytra (BL); length of elytron, measured from the highest point of basal margin to sutural angle (EL); maximum width of elytra (EW); width of head across eyes (HW); length of eye in sagittal plane (OL); width of pronotum between apical (PA) or basal (PB) angles; length of pronotum along median line (PL); distance between pronotal apex and level of maximum width of pronotum, measured along mid-line (PLw); maximum width of pronotum (PW). The measurements were taken using an eyepiece micrometer, to two decimal places. The means are given in round brackets for the ratios. All labels are printed unless otherABSTRACT. Nine species of the javanus species group of the genus Stenaptinus Maindron, 1906 from Vietnam are reviewed and a key to the species is provided. Two new species, S. dongnaiensis sp.n. from Vietnam and S. sumatrensis sp.n. from Sumatra, and a new subspecies, S. consularis flaviceps ssp.n. from Vietnam, are described. Three species, S. agnatus (Chaudoir, 1876), stat.rest., S. fimbriatus (Chaudoir, 1876), stat.rest., and S. stenoderus (Chaudoir, 1850) are resurrected from synonymy of either S. javanus (Dejean, 1825) or S. consularis (SchmidtGöbel, 1846). New synonymy is established: S. lissoderus (Chaudoir, 1850) = S. picicollis (Chaudoir, 1876), syn.n.; S. stenoderus = S. lei (Hrdlička, 2019), syn.n.; = S. snizeki (Hrdlička, 2019), syn.n.; S. agnatus = S. suensoni (Schauberger, 1923); = S. worthingtoni (Hrdlička, 2019), syn.n.
