Edaphus carinulifrons nov.sp. ( figs 2, 8 )

T y p e m a t e r i a l: Holotype (): VIETNAM: Hatinh Prov. , Raô An, 13 km W Huang Son, rt. 8 7 km S Nuòc Sôt village, 18 o 21’N, 105 o 15’E, 270m, litter near forest stream, 30.IV.1998, Lee Herman: in the AMNH.

D e s c r i p t i o n: Macropterous, reddish brown, moderately shiny, impunctate, pubescence recumbent.

Length: 1.0mm (fore body: 0.6mm).

PM of the ht: HW: 27; DE: 18.5; LE: 8; LT: 2.5; LG: 5; PW: 29.5; PL: 27; dlbc: 21; EW: 48; EL: 40; SL: 32.

M a l e: Sternite 8 ( fig. 8 ). Sternite 9 acute apicomedially, with 2 fields of about 14 ha. SpP large, twice as long as the aedeagus, with a double trumpet (similar to that of E. simulator PUTHZ : PUTHZ 2003, fig. 3 ), no vs. Aedeagus ( fig. 2 ).

Head slightly narrower than pronotum, eyes large, finely facetted, temples distinct, ptfF and alfF distinct, ampF about as broad as each of the alpF, with a narrow elevated carina, no distinct separation between ampF and clp, alpF each with 2 impressions (not carinate!). Antennae short, when reflexed not extending to the base of the pronotum, club 2- segmented, segment 10 slightly broader than long. Pronotum slightly broader than long, sides convex anteriorly, constricted behind, lbc distinct, elongated anteriad forming a very narrow longitudinal furrow extending to about the middle of pronotum; mbc extending to base proper, 6 distinct bf present; middle of pronotum with a narrow longitudinal incision/furrow, separate from the anterior margin of the pronotum by about the length of antennal segment 11. Elytra broader than long, sides slightly convex, slightly broadened behind, shoulders simple. Mbct3 about ¼ as long as the tergite.

C o m p a r a t i v e n o t e s: This new species belongs to the group of E. cinghalicus COMELLINI. It resembles this species strongly but may be distinguished at once by the non-carinate alpF and the narrower median carina of ampF. From E. philippinus BERNHAUER it may be distinguished by the distinct median furrow of the pronotum. In my key (1979b) it should be inserted at column 83.

E t y m o l o g y: Because of the carinated frons I name this species " carinulifrons " (Lat.= with a tiny carina of frons).
