03BE879CFFE2FFFDFE66FD3B41B8FAB2.taxon	discussion	Remarks This species was originally described based on a single female type (Pic 1930). During our study, the type was located at MNHN, as well as some additional specimens, making it possible for us to study this species in detail. The morphological characters, especially the structure of the aedeagus, show that it belongs to Stenothemus and not to Cantharis.	en	Yang, Yuxia, Ge, Shujuan, Yang, Xingke, Liu, Haoyu (2021): Review of the species of Stenothemus from Southeast China (Coleoptera, Cantharidae).

03BE879CFFE8FFF2FE28FD354153FCE6.taxon	discussion	Remarks The type was not located in MNHN although we tried several times; several specimens with labels written by Dr W. Wittmer with the specific name were found in NHMB. According to the previous work done by Wittmer (1969, 1972), it is speculated that he had examined the types during his working period, so the specimens determined by him are our references for the identification. Kazantsev (2007) introduced the new name Lycocerus limatus for L. limbatipennis (Pic, 1926) (originally in Podabrus), which was preoccupied by Lycocerus limbatipennis (Pic, 1906) (originally in Cantharis). Judging from the male genitalia, Podabrus limbatipennis Pic, 1926 is a member of Stenothemus, to which it is transferred here. With the change of the genus, the replacement name Lycocerus limatus Kazantsev, 2007 becomes a junior synonym of S. limbatipennis (Pic, 1926) (ICZN Article 59.4).	en	Yang, Yuxia, Ge, Shujuan, Yang, Xingke, Liu, Haoyu (2021): Review of the species of Stenothemus from Southeast China (Coleoptera, Cantharidae).

03BE879CFFECFFE8FE68F989474FFC9D.taxon	discussion	Remarks Wittmer (1982), having only females at his disposal, assigned this species to the genus Athemellus Wittmer, 1972, now a junior synonym of Lycocerus Gorham, 1889 (Okushima 2005). Some additional material, also including males from the type locality, is available here, and the morphological characters show that this species is a member of Stenothemus. Furthermore, the holotype male of Leiothorax atrosanguineus shows that it has no differences from S. chinensis comb. nov.; also, a large series of additional material from several localities is available for examination though their type localities are far away. Therefore, L. atrosanguineus is considered to be a junior synonym of S. chinensis.	en	Yang, Yuxia, Ge, Shujuan, Yang, Xingke, Liu, Haoyu (2021): Review of the species of Stenothemus from Southeast China (Coleoptera, Cantharidae).

03BE879CFFF4FFEEFDABFE4542F0FEA2.taxon	description	Supplementary description Male AEDEAGUS (Fig. 5 A ‒ C). Strongly swollen laterally in basal part, contracted in diameter apically; basal piece nearly as long as dorsal plate of each paramere, with a large, bifurcate conjoint middle nodule at base of ventral side; ventral processes of parameres nearly parallel to one another, distinctly thickened apically, bent dorsally in lateral view; dorsal plate slightly longer than ventral process, abruptly narrowed in middle and wide-triangularly protuberant at apical part, near to each other at basal part, apex acute and folded ventrally; apical parts of laterophyses depressed and separate from each other, apex acute and bent dorsally, reaching middle emargination between dorsal plates. Female ABDOMINAL STERNITE VIII (Fig. 8 F). Moderately narrowed posteriorly, posterior margin deeply and triangularly emarginate in middle and feebly emarginate on both sides; behind notch with membrane, narrowly bilobed at apex and present with longitudinal sclerite at center. INTERNAL ORGAN OF REPRODUCTIVE SYSTEM (Fig. 7 B). Vagina stout, with median oviduct situated at ventroapical part, diverticulum and spermathecal duct arising from apex; diverticulum extremely long, about 0.33 times body length, evenly thinned apically, slender tube-shaped and spiral; spermathecal duct much shorter than diverticulum; spermatheca slender tube-shaped and spiral, obviously thinner than spermathecal duct and nearly as long as diverticulum, with basal part extended into short tube, where accessory gland opening. Accessory gland thin and nearly as long as spermatheca.	en	Yang, Yuxia, Ge, Shujuan, Yang, Xingke, Liu, Haoyu (2021): Review of the species of Stenothemus from Southeast China (Coleoptera, Cantharidae).
