D e s c r i p t i o n: Macropterous, chestnut brown, shiny, pronotum with numerous very large puncture-like impressions, impunctate aside of minute setiferous punctures, pubescence, recumbent.

L e n g t h: 1.3mm (forebody: 0.7mm).

PM of the ht: HW: 34; DE: 23; LE: 10; LT: -; LG: 2; PW: 39; PL: 31; dlbc: 30; EW: 54; EL: 49; SL: 39.

M a l e: Sternite 8 (fig. 30). Sternite 9 acute apicomedially, no fields of ha present. SpP tubular, about 1.5x as long as the median lobe, vs smaller than apical portion of the

median lobe. Aedeagus (fig. 44), apical portion of median lobe concavely narrowed, parameres very stout, with one short apical and a slightly longer subapical seta.

Head distinctly narrower than pronotum, eyes large, no distinct temples present, ptfF distinct, alfF short, ampF broader than each of the elevated alfF, flat, no special separation between ampF and clp. Antennae short, when reflexed extending to about the posterior margin of the pronotum, club 2-segmented, segment 10 as long as broad, nearly as long as segment 11 (no sexual dimorphism). Pronotum broader than long, sides very slightly convexely dilated anteriad, lateral margination slightly curved up anteriorly, sides nearly straightly constricted behind; base with long lbc and 6 equally large bf, no mbc present; disc with 16 very large puncture-like impressions (fig. 14). Elytra large, broader than long, sides moderately convex, shoulders with a short intrahumeral stria extending cariniform mediad toward a small impression medially. Mbct3 long, as long as the tergite.

C o m p a r a t i v e n o t e s: This new species is remarkable by the very large pronotal impressions. It may be distinguished from its relatives as indicated in the key.

E t y m o l o g y: The name refers to the special characters of the pronotum, " foraminosus " (Lat.= full of holes).
