Taxonomic remark – Originally the species Chelonus subsulcatus w as de- scribedonthebasisofthemaleform (HErrich- SchäffEr 1838). Thesyntype series (itsnumberunknown) ofthisspeciesseemstobelost, i.e. typedepositoryneverindicated (cf. ShENEfElt 1973: 904). Furthermore, theoriginalde- scriptionofthespeciesis, unfortunately, veryshortandhardlysuitablefor therecognitionof ”subsulcatus” unambiguously. FAhriNgEr (1934: 424, 466) placedthisspeciesinhiskeyforthemales (p. 424) andpresentedarede- scription, partlyafterHErrich- SchäffEr (p. 466), underthename Chelonella subsulcata (HS.). Thefemaleformremainedunknownand, furthermore, the maleform, essentially, remainedalsounrecognizable. Henceuntilnowthe species ”subsulcatus” wasnotemendatedfromitsnomenoblitumstatus. WorthtonotethatTElENgA (1941: 305–306) placed Ch. subsulcatus inthelist ofuncertainspecies (speciesnomenincertum). Sinceitsdescriptionthespe- cies Ch. subsulcatus sankintooblivion. InHorN etal.
