Aleiodes castaneus sp. nov.

( Fig. 40 )

Holotype ♀, Thailand, Chiang Mai Province, Doi Inthanon National Park , checkpoint 2, 9.viii.2006, 18° 31.554’ N, 98° 29.940’ E, 1700m, Y Areeluck, (voucher BCLDQ00193, Genbank JF962541 ) ( QSBG).

Paratype ♂, Thailand, Chiang Mai Province, Doi Inthanon National Park, Kew Maepan Trail , 1.xii.2006, 8° 43.27’ N, 99° 40.263’ E, 2200m, Y Areeluck (voucher BCLDQ00245, Genbank JQ388461 ) ( QSBG) .

Length of body approximately 7.0– 7.5 mm, of fore wing 5.2–5.6 mm and of antenna 6.5–7.0 mm.

Antenna with 45 flagellomeres. Terminal flagellomere acuminate. Median flagellomeres 2 x longer than wide. Occipital carina variable, complete mediodorsally in holotype but distinctly obliterated medio-dorsally in paratype, ventrally. Mesopleuron largely rugulose superimposed on aciculate sculpture, speculum area largely with shiny aciculate sculpure, with only a small completely smooth area posteroventrally. Midlongitudinal propodeal carina complete. Fore wing vein 2-CU1 2.1 x 1-CU1. Apex of fore wing subbasal cell evenly setose. Fore wing vein 3-SR 2.15 x vein r. Fore wing vein SR1 2.27 x vein 3-SR. Hind wing vein M+CU 1.5 x 1-M. Hind wing subbasal cell with distinctly reduced setosty antero-distally. Hind wing vein m-cu well-developed, subtubular, straight, pigmented, interstitial. Apex of hind tibia without comb of modified adpressed setae. Claws without obvious pecten teeth. Basal lobes of 1 st tergite moderately produced, angular, steeply concave posteriorly. Midlongitudinal carina of 3 rd tergite distinct on anterior 0.6–0.7 of tergum.

Etymology. In reference to the similarity of the metasomal colour to that of chestnuts (Castanus).

Notes. Morphologically very close to A. basipunctatus sp. nov. but 2 nd metasomal tergite 1.1 x wider posteriorly than anteriorly. Differs from A. basipunctatus sp. nov. at 20 bases in the CO1 region sequenced, whereas the sequences of the two specimens of this species are identical.
