Gollumiella ochreata new species ( Fig. 2 )

Diagnosis. This species keys to G. longipetiolata in Heraty (1992). G. ochreata can be distinguished from all other species by the combination of dark brown coxae, yellowish white legs, basally striate and completely yellow petiole, and an elongate scape exceeding the ventral margin of the median ocellus, but not the dorsal margin. As well, the fore wing is 2.36–2.38 X as long as broad, as compared to G. longipetiolata , in which it is greater than 2.4 X as long as broad, and more than 2.5 X in the same gardens where the holotype of G. ochreata was collected. G. antennata also has a yellow petiole, but differs by having yellow coxae, smooth and curved petiole, nearly circular head in frontal view, and a short scape that reaches only 0.8 X the distance to the median ocellus.

Male. Length 2.17 mm. Dark brown; antennae, legs excluding coxae, petiole, and mandibles except for brown outer edge, pale yellow ( Fig. 2 ); distal tarsomere dark brown. Wings hyaline.

Head subtriangular, 1.23 X as broad as high. POL 0.75–0.85 X OOL. Face rounded and smooth with scattered fine setae, genae slightly convex in frontal view; occiput glabrous, dorsal angle with occiput abrupt and without sculpture. Clypeal margin truncate and with scattered fine setae. Eyes separated by 1.5–1.6 X their height. Malar space 0.70 X height of eye. Labrum with 4 long digits. Antenna 11 segmented; scape exceeding ventral margin of median ocellus, but length reaching only 0.88–0.96 X distance between torulus and upper margin of median ocellus, scape slightly expanded medioventrally; 8 funicular segments, FL1 and FL2 separated, combined length 2.3–2.6 X as long as broad, FL1 0.6– 0.8 X as long as FL2; flagellum 0.87 X height of head, setae of flagellum long, dense and semi­erect; clava tapering to acute point.

Mesosoma with rugose­alveolate sculpture, scutoscutellar sulcus deeply impressed and strongly transverse­carinate; scutellum as long as broad, frenal carina prominent and bisinuate. Propleuron with 4–5 transverse carinae. Coxae smooth and semi­globose, hind coxa 1.9–2.0 X as long as broad; hind femur bare laterally, tibia sparsely setose. Fore wing 2.36–2.38 X as long as broad, 2.88–3.03 X length of mesothorax; speculum closed basally by broad band of dense setae, basal area mostly pilose; venation distinct ( Fig. 2 ); submarginal vein dorsally with few minute setae basally, but otherwise bare; stigmal vein 2.0–2.5 X as long as broad and equal in width to apical group of sensilla; postmarginal vein 3.6– 4.0 X as long as stigmal vein.

Petiole 2.1–2.4 X as long as hind coxa, straight in profile, irregularly longitudinally striate but with distal fifth mostly smooth. Aedeagus broadly rounded.

Female. Unknown.

Distribution. Malaysia ( Malaya).

Type Material. Holotype, ɗ, “ Malaysia: Selangor, K.L., Univ. Malaya, Rimba Ilmu 03°07’43”N 101°39’29”E, 17.ix.2001 J. Heraty, 75m, sweep bot. gard. H01­045 / DNA voucher D# 426, UCR, J.M. Heraty”, deposited in USNM. Paratype: from same collection as holotype (1 ɗ, UCRC);

Molecular information. Three gene regions were sequenced for 1 individual. Data for the ribosomal transcript regions 28S­D2&D3 and 18S­E23 are deposited on GenBank as assession numbers AY552269 and AY552192 . Differs from G. longipetiolata that were collected sympatrically by 3 nucleotide differences (28S­D2:2; 28S­D3:1), and from G. buffingtoni by 9 differences (28S­D2:7; 28S­D3:2).

Etymology. From the Greek ochros, referring to the pale yellow petiole.
