Diagnostic combination. – Small size; brachypterous; habitus reminiscent of an Attelabidae , with a narrow head, broad rounded pronotum and short, broad-based elytra (Fig. 13a); lateroapical setae of pronotum absent, laterobasal setae missing in ¾ of specimens; umbilicate series of only 14 setiferous punctures; protibiae dorsally subcarinate, not distinctly canaliculate; apex of MTT4 shortly bilobate, without hyaline phanera.

Description

Habitus . – Fig. 13a. Brachypterous. Body length: 5.4-6.1 mm.

Colour. – Head, pronotum and elytra reddish-brown, with faint copperish reflections on the elytra; antennae and palpi flavo-testaceous;legs rufo-testaceous. Upper surface smooth and shiny.

Microsculpture, mesh pattern. –Head:slightly transverse, veryshallow; pronotum: obsolete; elytra: transverse, almost obsolete.

Head. – Elongate and narrow (Fig. 13b); eyes large but weakly convex; genae flat, hardly separated from the neck; vertex convex, collar constriction obsolete dorsally. Mandibles moderately long, acute at apex. Mentum tooth simple, triangular. Antennae moderately long, with three antennomeres extending backward beyond the base of the pronotum.

Prothorax. – Pronotum markedly transverse (PL/PW = 0.84), rounded, much wider at base than at apex, widest at middle. Hind angles obtuse, almost rounded, forming a lobe that protrudes backwards; sides evenly arcuate throughout; anterior angles completely effaced. Laterobasal impressions short and deep; lateral margins explanate basally, then gradually narrowing; base not bordered, apical margin bordered by a narrow, blunt bead. Lateroapical setae absent; laterobasal setae missing in ¾ of specimens (18 out of 24), but a small pore is always present close to the hind angle. Sides of the prosternal process not bordered.

Meso - and metathorax. – Elytra very short (EL/EW = 1.15), much broader than pronotum (EW/PW = 1.42); base truncate with bulging humeri, apex fusiform, separately rounded at tip, with no trace of subapical sinuation. Striae thin, shallow and faintly punctate on the disc, becoming gradually obsolete basally and laterally, and more deeply impressed near apex; interval 1 convex on the disc, intervals 2 and 3 subconvex, the following ones flat; all intervals convex or subconvex near apex. Parascutellar setiferous pore present; third interval with 2 or 3 small setiferous punctures: the first at basal fourth, the second at middle mm 2 mm 5, 0

(sometimes absent) and the third near apex. Umbilicate series of 14 setiferous punctures, distributed 6-8 or 5-2-7. Metathoracic wings vestigial.

Abdomen. – Last visible abdominal ventrite arcuate apically, with one pair ( ♂) or two pairs ( ♀) of setae along its apical margin.

Legs. – Moderatelyslender; metafemora without setae onanterior ridge. Protibiae dorsally subcarinate, not distinctly sulcate or canaliculate; and mesotibiae dorsally sulcate. Dorsal face of all tarsi convex, smooth, faintly sulcate laterally. MTT1 as long as MTT2+3. Apex of PT4, MST4 and MTT4 bilobate; apical lobes of PT4 and MST4 with long, spatuliform hyaline phanera; apex of MTT4 shortly bilobate, with a pair of normal (not hyaline) ventroapical setae; ventral face of MTT4 with two parallel rows of two setae. Fifth tarsomeres asetose ventrally.

Male genitalia. –Fig.13c. Median lobe elongate, median shaft strongly arcuate basally, then almost straight distally in lateral view; apex very short, relatively thick in lateral view, rounded in dorsal view. Endophallus without sclerotized structures.

Female genitalia. – Fig. 9d. Gonocoxite 2 arcuate, with 2 strong ensiform setae on the outer ridge. Bursa copulatrix very small, asymmetric, glabrous, with a basal lobe on the right side. Spermathecal duct nearly 3 times longer than the spermatheca; spermatheca small, fusiform; spermathecal gland with a moderately long duct connected to the base of the spermatheca.
