Edaphus hermani nov.sp. ( figs 11, 12 )

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, reddish brown, moderately shiny, pronotum and elytra densely, moderately coarsely punctate, pubescence recumbent.

Length: 1.3-1.4mm (fore body: 0.8mm).

PM of the ht: HW: 39; DE: 27; LE: 10; LT: -; LG 2; PW: 44; PL: 35; dlbc: 31; EW: 60; EL: 54; SL: 41.

M a l e: Sternite 6 with a shallow apical emargination, sternite 7 with a slightly deeper apical emargination, Sternite 8 ( fig. 12 ), Sternite 9 acute apicomedially, with two fields with about 14 ha. SpP tubular, about 1.5x as long as the aedeagus, vs smaller than apical portion of the median lobe. Aedeagus ( fig. 11 ), apical portion acutely angled, parameres much shorter than median lobe, with a long apical and a long subapical seta.

Head narrower than pronotum, eyes large, finely facetted, temples indistinct, ptfF and convergent alfF distinct, ampF as broad as each of the alpF, moderately callus-like elevated, anteriorly margined by convergent alfF, no sharp separation between ampF and clp. Antennae moderately long, when reflexed not extending to the posterior margin of the pronotum, club 2-segmented, segment 10 broader than long. Pronotum much broader than long, sides moderately convex anteriorly, strongly constricted behind, lbc distinct. mbc extending to base proper, 4-6 indistinctly delimited bf present; punctuation coarse and very dense (also behind bf), diameter of punctures about as large as median cross section of antennal segment 3, interstices much less than half diameter of punctures except on a minute area in anterior middle. Elytra trapeziform, much broader than long, sides moderately broadened, shoulders simple; punctuation distinctly less coarse than that on pronotum, dense, punctures larger than eye facets, interstices nearly as wide as diameter of punctures. Mbct3 shorter than half the tergite.

C o m p a r a t i v e n o t e s: This new species resembles closely E. punctatus FAUVEL , but may be distinguished by the impunctate frons, the slightly less coarse elytral punctuation, shorter antennal segment 10 (in E. punctatus it is longer than broad) and the aedeagus ( PUTHZ 1979b, fig. 8 ). In my key (1979b) it should be inserted at column 109; from E. rivalis PUTHZ , which is also relatively similar, it may be distinguished by the densely punctate base of the pronotum.

E t y m o l o g y: This new species is warmly dedicated to the collector Lee H. Herman (New York).
