description: <i>Pygatyphella nabiria</i> sp. n. (Figs 282, 291, 292, 300, 301, 308, 312, 313) <b>Holotype.</b> Male. <b>INDONESIA IRIAN JAYA</b>: 3.22S, 135.28E, Nabire 5–50m, 25.viii–2.ix.1962, JS (BPBM). <b>Paratypes</b> (2). Same data as for holotype (males) (BPBM). <b>Diagnosis.</b> One of the ‘ <i>obsoleta</i> ’ complex distinguished by the light brown dorsal colouration of the elytra which may lack darker markings, the very narrow posterior margin of T8 which has rounded and slightly projecting corners; short narrow prolongation of the inner apical margins of the LL, and the asymmetrical ML which bends left in a horizontal plane. <b>Male</b>. 6.4–6.7 mm long; 2.5–2.7 mm wide; W/L 0.4. Colour (Fig 282): Pronotum pale brown, posteromedian area marked in brown (extends to posterior margin); pronotum semitransparent and underlying pale fat body makes pronotum appear slightly paler than elytra, MN pale brown with median brown areas reaching inner and anterior margins; with posterior and lateral margins narrowly yellow; MS light brown with narrow median dark marking; elytra pale brown, semitransparent, lacking darker markings except for pale brown areas in posterior lateral areas, with fat body irregularly distributed in small clumps; head very dark reddish brown, antennae and palpi slightly lighter, inner margins of apical segments of both maxillary and labial palpi paler brown; under surface of thorax yellowish (metasternum appears light brown); legs yellowish with dark brown tarsi; basal ventrites light brownish yellow, V3 and 4 with median brown area that occupies about half the area, V5 very dark brown with paler anterolateral corners; LO creamy white, posterior area of V7 yellowish, semitransparent (muscle impressions visible); tergites brown, terminal two tergites semitransparent, yellow, heavily sclerotised. Pronotum: 1.3–1.4 mm long; 2.4 mm wide; W/L 1.8; lateral margins divergent posteriorly with angled convergence on both sides in 2/3, and rounded convergence in 1/3; posterolateral corners approximately 90° and angulate, inclined obliquely to the median line; slight kink in lateral margins on both sides in 1/3 and on left side only in 2/3. Elytron: parallel-sided; 5.1–5.3 mm long; with 2 well–defined interstitial lines. Head: can be retracted partially within prothoracic cavity and may not be visible from above; GHW 1.5 mm; SIW 0.15 mm; SIW/GHW 0.1; ASD&lt;ASW (sockets very close, not contiguous). Abdomen, ventrites (Fig. 308): LO in V7 reaches sides but not posterior margin and is shallowly bisinuate across its posterior margin; posterior area of V7 arched but not swollen; posterolateral areas of V7 rounded, corners not obvious. MPP as long as wide, dorsal surface lacking ridge; posterior margin squarely truncate. Tergites (Figs 312, 313): T8 longer than wide, lateral margins converge strongly posteriorly, much narrower across posterior margin, depending on orientation appears slightly medially emarginated; posterolateral corners rounded, projecting slightly; median longitudinal area flat with ridge like lateral margins, raised above slightly sloping sides; anterolateral prolongations elongate, narrow, expanded vertically and bases lacking projecting pieces. Aedeagal sheath: emargination of right side of sternite begins at point of attachment of tergal arms laterally. Aedeagus (Figs 291, 292, 300, 301): L/W&gt;3/1; LL/ML moderate; LL not strongly divergent along their length dorsally, and a little shorter than ML at their apices; outer preapical area of LL produced angulate; inner apical area of LL prolonged, short, narrow; base of LL asymmetrically produced to left; ML lacking lateral teeth. <b>Female, Larva.</b> Not associated. <b>Etymology.</b> The specific name, the type locality, is considered as a noun in apposition.
