( Figs 414–420 )

Bungona (Chopralla) pontica Sroka, Godunko & Gattolliat (in Sroka, Godunko, Rutschmann, Angeli, Salles & Gattolliat) 2019: 3 (larva);

Material examined. Photos of paratypes provided by R. Godunko and P. Sroka.

Distribution. Turkey.

Comments. Centroptella pontica is known as larvae only. Judging by hypodermal coloration of mature male larva, abdomen of male imago should have extensive reddish coloration on abdominal terga II–III and V–VI ( Fig. 418 ). Judging by subimaginal legs visible through cuticle of mature female larva, tarsus of middle and hind legs has 1 apical spine on initial 3rd tarsomere (next after 1st+2nd tarsomere) ( Fig. 415 ); in female—also with 1 apical spine (on tarsomere next after 2nd tarsomere ( Fig. 414 ). A retained fragment of subimaginal gonostylus inside larval protogonostylus ( Fig. 420 ) testifies that subimaginal gonostyli are folded in the « Crassolus - type » pose [see Crassolus (5)].
