Genus Akmazeina n. gen.

TYPE SPECIES. — Akmazeina santonorum n. sp .; here designated.

ETYMOLOGY. — Generic name is derived from Ancient Greek akmazein, be in the prime of the youth; gender feminine.

DIAGNOSIS. — Differs from Neazonia Szwedo, 2007 in subtriangular vertex (more pentagonal in Neazonia ); wider trigons (trigons narrow in Neazonia ); sensory pits only in upper portion of frons (two pairs of sensory pits in upper and lower portion of frons in Neazonia ); submedian carinae fused, diverging only in upper portion of frons (submedian carinae diverging from frontoclypeal suture in Neazonia ); disc of pronotum slightly elevated, delimited by semicircular carinae (carinae straight and diverging in Neazonia ); hind tibia with distinct, knee lateral tooth (hind tibia lacking lateral teeth in Neazonia ).

DESCRIPTION

Body slender, somewhat elongately ovoid. Head and thorax measured in midline shorter than abdomen with pygofer in midline; head and thorax with wing pads measured to the tips of wing pads about as long as abdomen with pygofer in midline. Vertex with distinct trigons, disc of vertex subtriangular, delimited by elevated carinae, posterior margin slightly elevated. Frons with distinct, subparallel lateral carinae; submedian carinae weak, slightly diverging near the margin of frons and vertex; quadruplet of sensory pits in upper portion, laterad of midline. Rostrum distinctly exceeding length of body.

Pronotum wider than head with compound eyes, with elevated disc delimited anteriolaterad by semicircular carinae; a pair of rosette-like triplets of sensory pits laterad of ecdysion line. Mesonotum with wing pads wider than pronotum; metanotum with wing pads about as wide as mesonotum with wing pads.

Fore and mid femora slightly flattened, carinate, fore and mid tibiae subquadrangular in cross section. Hind femur slightly flattened; hind tibia elongate, subquadrangular in cross section, with distinct knee tooth and rows of setae along margins.

Abdominal tergites IV-VII with single sensory pits near lateroposterior angle; tergite VIII with triplet of sensory pits. Pygofer triangular, with distinct median incision ventrally, reaching half of pygofer length; lateral lobes with triplets of sensory pits near half of pygofer length; posterior margins of pygofer lobes excavate, processes of IXth abdominal sternite (“anal combs”) elongate, finger-like; Xth tergite plate-like, carinate.
