Edaphus latipennis nov.sp. ( figs 5, 10 )

T y p e m a t e r i a l: Holotype () and 1 - paratype: 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, moderately shiny, Pronotum and elytra punctate, pubescence recumbent.

Length: 1.4-1.5mm (fore body: 0.9mm).

PM of the ht: HW: 38; DE: 24; LE: 12; LT: -; lG: 1.5; PW: 43; PL: 36; dlbc: 31; EW: 62; EL: 59; SL: 50.

M a l e: Sternite 8 ( fig. 10 ). Sternite 9 acute apicomedially, no fields of ha. SpP tubular, about twice as long as the median lobe, vs about as large as apical portion of the median lobe. Aedeagus ( fig. 5 ).

Head narrower than pronotum, eyes large, finely facetted, no temples, ptfF and (short) alfF distinct, ampF nearly twice as broad as each of the alpF, flat, no apical separation between ampF and clp, alpF moderately elevated with a distinct impression anteriorly. Antennae when reflexed not extending to the posterior margin of pronotum, club 2-segmented, segment 10 slightly longer than broad. Pronotum broader than long, sides moderately convex anteriorly, distinctly constricted behind, lbc distinct, no mbc, 6 indistinctly delimited bf amongst the dense punctuation present; punctuation coarse and dense, diameter of punctures about as large as basal cross section of antennal segment 3, interstices less than half diameter of punctures. Elytra very large, broader than long, sides moderately broadened behind, slightly convex, shoulders simple; punctuation much finer than that on pronotum, dense, punctures about as large as eye facets, interstices about as wide as diameter of punctures. Mbct3 nearly as long as the tergite.

C o m p a r a t i v e n o t e s:InmykeytotheOriental Edaphus ( PUTHZ 1979b) this new species should be inserted at column 190. From E. strangulatus CAMERON it may be distinguished by the size ( E. strangulatus : 1.1-1.3mm), the very densely punctate pronotum (also in basal quarter) and 6 bf. From E. feai PUTHZ which also runs at column 190 it may be distinguished by smaller size ( E. feai : 1.6-1.9mm), impunctate frons and finer elytral punctuation, from both by the aedeagus.

E t y m o l o g y: Because of the large elytra I name this species " latipennis " (Lat.= with large elytra).
