Aleiodes rivulus sp. nov.

( Fig. 154 )

Holotype ♂, Thailand, Chiang Mai Province, Doi Phahompok NP, Kiewlom montane forest, 28.i.2008, 20° 3.549' N, 99° 8.582' E, 2174m, P Wongchai (voucher BCLDQ01646, Genbank JN278372 ) ( QSBG).

Paratype: 1 ♂, same data as holotype and mounted on same card rectangle closer to pin with all legs present (no sequence data) ( QSBG) .

Body length 3.5 mm, fore wing length 3.5 mm and antenna length 4.6 mm.

Antenna with 35 flagellomeres. Terminal flagellomere acuminate. Occipital carina weak but complete medio-dorsally, rounded, ventrally joining hypostomal carina. Mesopleuron shiny, rugose anteriorly, largely smooth posteriorly including large specular area, precoxal sulcus deep foveate rugose, speculum large. Midlongitudinal propodeal carina complete. Propodeum coarsely foveate rugose. Fore wing vein 2-CU1 1.0 x 1- CU1. Apex of fore wing subbasal cell evenly setose. Fore wing vein 3-SR 1.2 x vein r. Fore wing vein 2-SR+M 0.85 x vein r. Fore wing vein SR1 3.5 x vein 3-SR. Hind wing vein M+CU 1.8 x 1-M. Hind wing subbasal cell evenly setose. Hind wing vein m-cu well-developed, long, curved pigmented,position variable, far antefurcal in holotype, interstitial in paratype. Apex of hind tibia with comb of especially modified and adpressed setae medially and ventrally between hind spurs. Claws without conspicuous pecten. Basal lobes of 1 st tergite hardly produced, rounded. Midlongitudinal carina of 3 rd tergite not differentated from other strong longitudinal striation.

Etymology. Latin for a rivulet in allusion to the pattern of striation on the 3 rd metasomal tergite.
