Babylas Horváth, 1915

Type species: Babylas bihamatus Horváth, 1915 , by original monotypy.

Babylas Horváth, 1915: 224 , 241–242 (keyed); Gross, 1976: 255. (descriptive note, taxonomic position)

Redescription. Head coarsely punctate; vertex flat; juga acute apically, rounded laterally; antennifers stout, acute, visible from above. Antennae with segment I surpassing apex of head, distal third wider than proximal portion, remaining segments of antennae terete. Compound eye subglobose, slightly stalked; ocelli located posterior to imaginary line between posterior margin of eyes. Pronotum deeply punctuate, subrugose, collar formed by constriction just behind anterior margin; anterolateral margins sinuate; posterolateral margin sinuate; posterior margin slightly concave. Scutellum elongate, triangular with low median raised longitudinal line; apex acute, dorsally reflexed. Forewings just surpassing abdomen; corium shallowly punctuate. Laterotergites narrowly visible from above, posterior angle slightly produced.

Bucculae parallel-sided, becoming obsolete prior to reaching posterior margin of head; anterior angle of bucculae acute, directed anteroventrally; labium elongate, just surpassing metacoxae. Prosternum sulcate. Mesosternum slightly depressed without obvious median raised carina, posterior margin shallowly bilobed. Metasternum shallowly sulcate, swollen laterally, posterior margin concave. Ostiole of metathoracic scent gland circular; peritreme strap–shaped, curved anteriorly, apically rounded, 5–6X longer than wide, reaching over half of distance from ostiole of metathoracic scent gland to lateral metapleural margin; evaporative area covering much of meso- and metapleura. Posterior margin of metapleura straight to slightly curved, posterolateral lobe absent. Venter of abdomen with posterior margin of sixth sternite (fifth visible) “V”-shaped; trichobothria paired, transverse, posterior to spiracles.

Males. Pygophore with elongate narrow dorsal lobes Paramere reduced, fused to interior portions of proctiger.

Females. Posterior margin of seventh sternite (sixth visible) with broad medial “U”–shaped emargination. Eighth gonocoxae broadly triangular with a distal lobe.

Comments. Among genera in the Solomonius -group, Babylas is most similar to Auxentius . Babylas is distinguished by its robust, projecting inner and outer ventral rims on the pygophore ( Fig. 14B ). Unlike Auxentius , the eighth gonocoxa in females is well-developed in Babylas .
