Edaphus scrobiculicollis nov.sp.

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, 300m, flight interception trap, 9.-22.V.1998, Lee Herman: in the AMNH.

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

Length: 1.2-1.3mm (fore body: 0.8mm).

PM of the ht: HW: 34.5; DE: 23; LE: 9.5; LT: 2; LG: 3; PW: 39.5; PL: 34; dlbc: 26; EW: 54; EL: 48; SL: 38.

M a l e: Unknown.

Head narrower than pronotum, eyes large, finely facetted, temples distinct, ptfF and alfF distinct, ampF as broad as each of the callus-like elevated alpF, convex/distinctly elevated, no special separation between ampF and clp, alpF with a distinct impression anteriorly. Antennae moderately long, when reflexed not extending to the posterior margin of the pronotum, club 2-segmented, segment 10 distinctly broader than long. Pronotum broader than long, sides strongly convex anteriorly, strongly constricted behind, lbc and mbc (extending to base proper) distinct, 4-6 bf present; mbf elongated anteriad nearly toward the middle of pronotum; a distinct fovea in the disc medially in each pronotal half. Elytra large, broader than long, sides moderately broadened, slightly convex, shoulders simple. Mbct3 shorter than half the tergite.

C o m p a r a t i v e n o t e s:Thisnewspeciesresembles E. bipunctatus PUTHZ from Vietnam, but may be distinguished by the shorter mbf, 4-6 bf, longer elytra and the pronotal foveae, which are placed in the middle of each half of the pronotum (not in the actual middle of the pronotum as in E. bipunctatus ). The species resembles also E. biimpressus PUTHZ from Vietnam, but is more robust and has shorter elytra. In my key (1979b) it should be inserted at column 80; from E. fossicollis PUTHZ it may be easily distinguished by the smaller size.

E t y m o l o g y: Because of the small foveae in the middle of the pronotum I name this species " scrobiculicollis " (Lat.= with foveae on pronotum).
