Ambohitantelya gen. nov.

( Figs. 1–14 )

Type species: Ambohitantelya yuripopovi sp. nov.

Diagnosis. Apterous, surface of body granulate except fused metanotum + mtg I+II, tergal plate and median parts of metasternum and sternites III–VII. Differs from all described apterous Madagascan Mezirinae by the shape, size and dorsally expanded metathoracic evaporatoria.

Description. Head. About as long as wide or slightly wider, clypeus short reaching 1/3 of antennal segment I, its apex free; genae thin adherent to clypeus; antenniferous tubercles short and blunt, antennae about twice as long as width of head, segment I thickest, II shortest, III longest, IV fusiform; eyes globose inserted in head, granular; postocular lobes with round tubercles converging posteriorly to constricted neck; surface of vertex with rugosities and granules. Rostrum arising from a slit-like atrium, about as long as head.

Pronotum. Trapezoidal about 2.5x as wide as long at middle; median anterior margin ring-like, laterally separated from raised lateral granulate elevations by deep incisions, surface with ovate callosities and deep furrows.

Mesonotum. Strongly transverse, fused to pro- and metanotum; disk with a median longitudinal furrow, laterally flanked by granulate ridges, lateral margins raised and granulate partly covered by the dorsally expanded evaporatoria of metathoracic scent glands.

Metanotum. Completely fused to mtg I+II forming a trapezoidal smooth plate with 2 (1+1) shallow depressions lateral of median carina; anterior and posterior margins slightly carinate, lateral margins granulate.

Abdomen. Tergal plate smooth and shiny with flat apodemal impressions; surface of deltg II–VII granulate, each with 2 larger patches of raised tubercles; lateral margins evenly rounded, pe-angles not protruding; deltg II+III fused, triangular, anteriorly reaching metanotum, mtg VII granulate.

Venter. Fused median part of metasternum + mst III–VII smooth and shiny, other parts rugose and granulate ( Fig. 6 ); metathoracic scent gland evaporatoria large and expanded anterolaterally and dorsally; all spiracles placed on tubercles, II+III lateral and visible from above, IV–VII sublateral and hardly visible from above, VIII terminal on paratergites VIII.

Legs. Long and slender, unarmed, claws with thin pulvilli.

Etymology. Named after the Ambohitantely Special Reserve in Central Madagascar, where this new genus was discovered.
