sp. n.

Pygatyphella kiunga sp. n.

( Figs 317, 319–320, 327–328)

Holotype. Male. PAPUA NEW GUINEA: Western Pr. , Fly River, Kiunga, 35 m, viii.1969, JS, ( BPBM).

Paratypes (4). Same data as holotype, males ( BPBM) .

Diagnosis. Similar to Pygat. peculiaris , differing in the wider apex of the MPP, lacking the dorsal projections of V7, and with very narrow apices of the LL.

Male. 9.5–10.8 mm long; 4.0– 4.5 mm wide; W/L 0.4. Colour ( Figs 317, 319): Pronotum yellow, semitransparent in 4/5, dingy pale brown in 1/5, fat body retracted in posterolateral areas, either with faint traces of paired median brown areas in 4/5, or with wider and more obvious brown areas in 1/5 (colour may be a reflection of underlying muscles); anterolateral corners narrowly brown on ventral surface (visible from above depending on orientation); MN yellow with median brown areas, reaching inner margins in 1/5; MS yellow with median dark marking, broad anteriorly (occupying about half width anterior area) in 3/5; elytra pale yellowish, semitransparent, with extensive brown markings at base and apex; basal dark area not extending to anterior margin and irregularly emarginated along lateral margin near MS, not covering humerus; inner margin of basal dark area extending along suture for approximately half its length, outer margin of basal dark area extending for about half this length posteriorly and then running obliquely and slightly irregularly across to suture; apical dark marking an elongate somewhat irregular oval, reaching suture and lateral margins narrowly along its posterolateral edges; 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 1 yellowish with anteroventral face of femora, ventral surface of tibiae and ventral surface of tarsi brown; legs 2 and 3 yellowish (a median orange line along the anterior face of the femora is probably due to the underlying muscle); basal ventrites light brownish yellow; LO creamy white, posterior area of V7 yellowish, semitransparent (muscle impressions visible); tergites brown, terminal two tergites orange yellow, heavily sclerotised. Pronotum ( Fig. 317): 2.0– 2.3 mm long; 3.5–4.0 mm wide; W/ L 1.7; lateral margins divergent posteriorly with angled convergence on both sides in 5/6, and angled convergence on one side and rounded on the other in 1/6; posterolateral corners approximately 90°, angulate, inclined obliquely to median line; slight kink in lateral margins on both sides in 5/6. Elytron: parallel-sided; 7.5–8.5 mm long; with 2 well–defined interstitial lines. Head: can be retracted almost completely within prothoracic cavity and may not be visible from above; GHW 1.9–2.0 mm; SIW 0.2 mm; SIW/GHW 0.1; ASD<ASW (sockets very close but not contiguous). Abdomen, ventrites ( Fig. 320): LO in V7 reaches to sides, not posterior margin, shallowly medially emarginated across posterior margin; posterior area of V7 arched and swollen; posterolateral areas of V7 rounded, corners not obvious. MPP as long as wide, dorsal surface lacking ridge; posterior margin rounded (slightly medially emarginated in 1/5). Tergites: T8 with slightly developed and laterally margined median longitudinal groove on ventral surface; anterolateral prolongations elongate, narrow, expanded vertically and lacking projections at their bases. Aedeagal sheath: emargination of right side of sternite begins at point of attachment of tergal arms laterally. Aedeagus ( Figs 327, 328): L/W>3/ 1; LL/ML moderate; LL divergent along their length dorsally, just shorter than ML at very narrow apices; LL apices narrower than ML apex, lacking outer preapical expansion and inner apical prolongation; preapical inner margin of LL with very small tooth; base of LL asymmetrically produced (to the left); ML lacking lateral teeth.

Female, Larva. Not associated.

Etymology. The specific name, the type locality, is considered as a noun in apposition.
