Diagnosis

A distinctive morphological structure of D. bavarica sp. nov. is the tegmen: its sclerotization is stronger than usually found in this genus and the construction includes unusual details, such as a pair of large, subtriangular outgrowths ventrobasally (↓ 1, Fig. 18B) and a pair of tiny spikes subapically (↓ 2, Fig. 18B). 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.

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).
