Edaphus torifrons nov.sp. (figs 15, 36, 55)

T y p e m a t e r i a l: Holotype (): SURINAME: Brokopondo, Brownsberg Nature Preserve, Witi Creek Trail, 420m, 4 o 56’55’’N, 59 o 10’53’’W, FIT, 23.-25.VI.1999, Falin et al.: in the KSEM.

D e s c r i p t i o n: Macropterous, reddish brown, shiny, aside of setiferous punctures impunctate; pubescence recumbent.

L e n g t h: 1.0- 1.3mm (forebody: 0.75mm).

PM of the ht: HW: 33.5; DE: 21; LE: 10; LT: -; LG: 3; PW: 37.5; PL: 30; dlbc: 27; EW: 53; EL: 47; SL: 38.

M a l e: Sternite 8 (fig. 36). Sternite 9 acute apicomedially, no fields of ha present. SpP about 1.5x as long as the median lobe, with a distinct double trumpet, vs small (fig. 15). Aedeagus (fig. 55), median lobe acutely angled narrowed (with 2 setae (?)), parameres shorter than median lobe, with 1 short apical and 1 slightly longer subapical seta.

Head distinctly narrower than pronotum, eyes very large, finely facetted, distinct temples absent, ptfF semicircular, distinct, alfF absent, alpF elevated, anteriorly coalescent with a transverse bulge, ampF = transverse bulge. Antennae moderately long, when reflexed extending to the posterior margin of the pronotum, club 2-segmented, segment 10 slightly broader than long, segment 11 about 1/3 longer than segment 10. Pronotum much broader than long, sides convex anteriorly, strongly constricted posteriorly; lbc and mbc (extending to base proper) distinct, 6 distinctly delimited bf present, lbf twice as small as mbf. Elytra broader than long, sides shallowly concavely dilated, shoulders simple. Mbct3 nearly extending to the posterior margin of the tergite.

C o m p a r a t i v e n o t e s: Aside of the sexual characters of the male this new species is remarkable by the absence of a distinctly delimited ampF. It may be distinguished from other relatives as indicated in the key.

E t y m o l o g y: The name of this new species refers to the transverse anterior bulge of the frons.
