description: 31. Parvisquama vanuatuensis, sp. nov.   
(Figs 11–13)  
 Holotype. Male, deposited in BMNH, labeled: Vanuatu (as New Hebrides): Tanna: x.1930 (L.E. Cheesman).   
 Diagnosis. Postpedicel mainly yellow, darkened in apical third; palpus dark brown; scutum densely grey pollinose, with very faint vittae; mid femur with the posteroventral ground-setulae in apical half becoming distinctly short-spinulose and comb-like; sternite 5 of male with the posterior lobes short and rounded, with short setulae on disc and bare along inner surface (Fig. 12); surstylus with almost whole surface covered with tiny setulae (Fig. 13).   
 Description. Male. Length. Wing: 2.7–2.9 mm.   
Head. Ocellar setae minute. Lower orbital slightly closer to upper frontal than to upper orbital. Pedicel brown, orange at tip; postpedicel mainly yellow, darkened in apical third. Palpi brown.  
 Thorax. Scutum grey dusted, with weak indications of a pair of paramedian brownish vittae running along dorsocentral rows. Acrostichal setulae in 2 rows. Anterior postsutural intraalar, presutural intraalar and inner postpronotal very short. 2 proepisternal setae. Scutellum grey dusted; basal setae short, and disc with 3-4 setulae. Wing very long and narrow. Vein A 1 +CuA 2 very short, not reaching halfway from its base to wingmargin. Lower calypter linear. Knob of haltere pale yellow. Legs including coxae yellow, on all legs only tips of tarsomeres 3 and 4 darkened and most of tarsomere 5 black. Fore tibia without a posterior seta. Mid femur on ventral surfaces with short setulae, those on posteroventral surface becoming more comb-like and spinulose in apical half; with a strong anterior seta just beyond middle, and 1 posterior preapical seta. Mid tibia with 1 posterior seta, without anterodorsal. Hind femur with 1 short posteroventral just before apex and 1 stronger seta at middle, and with 2 anteroventral setae, one at apical 2/3 and one before apex; anterodorsal row complete (including a preapical seta) and 1 posterodorsal preapical. Hind tibia with 2 anterodorsals, 2 posterodorsals, 1 anteroventral, 1 dorsal and 1 anterodorsal preapicals, without posteroventral apical.   
Abdomen. Sternite 5 as in Figs 11–12.  
Terminalia. Surstylus as in Fig. 13.  
 Material examined (paratypes): BMNH: Vanuatu: Aneityum: Red Crest, 1200 feet, 3 km NE of Anelgauhat, iii.1955, 2 ♂, L.E. Cheesman.   
 Comments. All three males (holotype and paratypes) are in very poor condition, but the terminalia show that they represent a different, and undescribed, species. The holotype is the best preserved but is covered with numerous Lepidoptera scales.   
 Distribution. Known only from Vanuatu, from Tanna and Aneityum Islands.
