Autapomorphies of Raptobaetopus/g1.

(1) Mouth apparatus is modified and more deeply adopted to carnivorism, than in Baetopus/g2: 

Labrum without median incision [see Turbanoculata (4)]. 

Mandibles are shortened perpendicular to axis of articulation, incisor is elongate. 

Maxillary canines and distal dentiseta are elongate, being pressed together they form a claw-like structure (similar in shape, but not in composition of parts with that of Prosopistoma/f1=g2 and Ameletopsis/fg1).

Characters of Raptobaetopus/g1 of unclear phylogenetic status. 

(2) Prostheca of right mandible not bifid, i.e. without long process ( Müller-Liebenau 1978: Abb. 9b).

(3) 2nd+3rd segment of labial palp [see Baetopus/g1 (1)] is thickest near base, narrowing toward apex.

Variable characters of Raptobaetopus/g1. Tergalii are either all I–VII pairs, subequal and oval (in tenellus [Centroptilum] and orientalis [Raptobaetopus]), or III–VII only, with V–VII greatly elongate (in undescribed species from Lombok), or V–VII only, translocated ventrally and greatly modified (in sartorii [Cymbalcloeon]).

Size. Fore wing length 3–4 mm (see Tetramerotarsata).

Distribution. Palaearctic and Oriental Region.
