Larvae and females of the new species are unknown. Etymology The specific epithet is derived from Bavaria , the federal state where the holotype specimen was collected. Type material Holotype GERMANY • ♂ ; Bavaria , Weilheim , Pähl , Hartschimmelhof ; 47°93′99″ N , 11°18′30″ E ; 20 Jun.‒12 Jul. 2020 ; D. Doczkal and K. Grabow leg.; Malaise trap ; fen; ZSM-DIP-42303-E06 . Fig. 18. Divellepidosis bavarica sp. nov. , holotype, ♂ (ZSM-DIP-42303-E06). A . Terminalia, ventral view. B . Parameres, with aedeagal apodeme indicated, ventral view. C . Fourth flagellomere, lateral view. Scale lines: 0.05 mm. The numbered arrows indicate diagnostic characters (see text). Other characters Male BODY LENGTH . 1.5 mm . HEAD . Eye bridge dorsally 4‒5 ommatidia long. Antenna slightly longer than body; circumfila present on flagellomeres 1‒8; neck of fourth flagellomere 1.4× as long as node ( Fig. 18C ). Palpus 4-segmented, about as long as head height. THORAX . Anepisternum with 1 seta. WING . About as long as body. Length / width ratio 2.7. LEGS . Acropods, to assess structure of claws and empodia, not retained. TERMINALIA . Gonocoxal synsclerite broader than long, without separate narrow portion at base; ventroanterior margin clearly contoured, even slightly reinforced, which is unusual in Divellepidosis ; ventral emargination small, broadly U-shaped, with broad sclerotized margin; protuberances small, abruptly protruding, each with 2 large setae (↓ 3 , Fig. 18A ); processes large, thin-membranous, glabrous (↓ 4 ); dorsoposterior portions protruding beyond ventroposterior portions. Gonostylus ( Fig. 18A ) tapered towards apex, with at least 3 plate-like teeth apically, ventralmost largest, inside with 1 long subapical bristle. Aedeagal apodeme ( Fig. 18A ) markedly longer than gonocoxae, moderately sclerotized, pointed apically. Membranous portions of aedeagus extensive (indicated in Fig. 18A‒B ).
