Aleiodes (Hemigyroneuron) pseudospeciosus Quicke & Butcher sp. nov.

( Figures 23 , 24 )

Material examined

Holotype. Female , “ BRUNEI: 100’ Badas, Agathis forest, 25–26.ii.1982 ” ( BMNH).

Morphology

Length of body 9.1 mm, and of fore wing 8.6 mm.

Head. Antenna with 68 flagellomeres; terminal flagellomere pointed but not acuminate; strongly transverse, 1.68 times wider than maximally long in dorsal view; width of head 2.7 times shortest distance between eyes; height of eye 1.75 times shortest distance between eyes; frons smooth and shiny, with some curved ridges paralleling the antennal sockets anteriorly, with short mid-longitudinal sulcus posteriorly; posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.5: 4.7: 1.0; occiput punctate-rugulose; occipital carina complete.

Mesosoma . Mesoscutum coriaceous-rugulose and densely short-setose; notauli undefined; mesopleuron with a large, slightly concave area of fine dorso-ventral striation; prepectal carina incomplete, dorsally becoming confused in area of fine striation; scutellar sulcus with five carinae between the outer ones; scutellum with rather coarse, transverse-rugulose sculpture superimposed on strongly aciculate background; with disc margined by carina on anterior half; propodeum coarsely foveate-reticulate superimposed on aciculate sculpture, with well-developed though rather irregular midlongitudinal carina on anterior 0.7, with slightly protruding postero-lateral tubercles but these not ridge-like.

Fore wing. Subbasal cell largely glabrous, with distinct, large, oval, glabrous sclerome just distal to vein 1-M; posterior half swollen due to vein M+CU having an angulation at approximately 0.7 distance from base; vein 1-CU1, straight, 1.5 times length of 2- CU1; vein cu-a more or less vertical, weakly curved, somewhat swollen anteriorly and narrowing posteriorly; length of veins r: 3-SR: SR1 = 1.0: 1.75: 4.0; vein 2-M 2.5 times length of r-m; vein m-cu 2.0 times length of 2-SR+M, forming angle of 130 ◦ with 3-CU1.

Hind wing. Vein M+CU 1.17 times length of vein 1-M; vein 2-SC+R marginally tranverse; basal, subbasal, and antero-basal part of discal+subdiscal cells glabrous.

Claws. With three or four fine pectinal teeth on basal half of basal lobe.

Metasoma. Tergites 1, 2 and basal 0.4 of tergite 3 longitudinally striate with irregular punctures between the striae; 2nd tergite 1.5 times wider than medially long, 1.3 times longer than 3rd.

Colouration

Antennae black with flagellomeres 19–42 white. Head largely ivory-white with black clypeus, triangular mark in mid-lower face, frons, vertex and occiput. Mesosoma black with ivory-white marks on anterior and posterior of pronotum and propleuron, mid-posterior of mesoscutum, postero-dorsal of mesopleuron, postero-ventral of metapleuron. Fore and mid coxa, trochanter and trochantellus, mid tarsus, hind trochanter, basal half of tibia and basal four tarsal segments ivory-white; hind coxa largely black and apex of hind femur black; rest of legs yellow-brown. Metasoma ivory-white with black transverse bands on middle of 1st tergite, near but removed from base of 2nd tergite, and broadly basally on 3rd–6th tergites. Wings hyaline with dark brown venation except most of fore wing vein C+SC+R and anterior margin of pterostigma brown-yellow.

Etymology

Named because of its close similarity to A. (H.) speciosus (Baker) .
