description: <i>Pygatyphella karimui</i> sp. n. (Figs 279–281, 284, 289, 290, 298, 299, 304–306) <b>Holotype.</b> Male. <b>PAPUA NEW GUINEA</b>: Chimbu Pr., 6.30S, 144.50E, Karimui 1080 m, 14.vii.1963, JS (BPBM). <b>Paratypes</b> (6). Same data as holotype, 4 males, 2 females (BPBM). <b>Diagnosis.</b> One of the <i>obsoleta</i> ‘complex’ distinguished by the strongly arched and swollen V7, the broad apically truncate MPP, and the very narrow apices of the LL of the aedeagus. <b>Male.</b> 8.4–9.6 mm long; 2.8–3.3 mm wide; W/L 0.3. Colour (Fig. 279): Dorsal surface light brown, mostly semitransparent with fat body showing through the cuticle, and brown markings in median area of pronotum (small, paired, and faint), a narrow median dark band on the MS which reaches anterior margin, narrowly dark along the basal ¼ of suture from posterior margin of MS, small brown area at base of elytra between bases of interstitial lines 1 and 2, and two small preapical brown spots, one at posterior end of interstitial line 1 and the other at outer margin; head antennae and palpi very dark; ventral aspect of thorax yellowish except for brown metasternum; legs yellow with brown tarsi; basal ventrites yellowish, V5 dark brown with anterolateral pale patches; LO yellowish, posterior area of V7 yellowish with underlying muscle impressions clearly visible; basal tergites brown, T7 and 8 yellow. Pronotum (Fig. 284): 1.6–1.8 mm long; 2.9–3.3 mm wide; W/L 1.8; lateral margins with rounded (3/5) or angulate (1/5) convergence, and indentations in lateral margins in 5/5; posterolateral corners angulate, &lt;90° and inclined obliquely to the median line. Elytron (Fig. 279): parallel-sided; 6.8–7.8 mm long; with 2 well–defined interstitial lines. Head: can be partially retracted into prothoracic cavity, narrowly visible from above in resting position; GHW 1.9–2.0 mm; SIW 0.15mm; SIW/GHW 0.08; ASD&lt;ASW (sockets very close). Abdomen, ventrites (Figs 304–306): LO retracted into anterior 1/3 of V7 where it may not reach sides, not reaching posterior margin, posterior margin either entire or slightly and narrowly produced in 1/5; V7 arched and swollen; posterolateral corners rounded angulate; muscle impressions extend almost to tip of MPP. MPP moderately broad, apex squarely truncate; dorsal surface with a wide median ridge (Fig. 306, arrowed). Tergites: T8 (Fig. 306) very well sclerotised, about as long as wide, thickened lateral margins converge gently posteriorly; anterolateral prolongations elongate, narrow, expanded vertically, more widely so in median area; ventral surface with a slightly developed long median trough with fine lateral margins. Aedeagus (Figs 289, 290, 298, 299): L/W&gt;3/1; LL/ML moderate; lateral margins of LL converge posteriorly and LL narrow at apices; LL not divergent along dorsal length except near apices, slightly shorter than ML; outer preapical margin of LL slightly produced and rounded, inner apical margin produced, short and narrow; base of LL asymmetrically produced to left; ML lacking teeth at about level of ejaculatory orifice, symmetrical, not curved left horizontally; dorsolateral margins of ML behind apex slightly produced and pointed (may be visible from beneath as tooth like projections (Figs 289, 290, 298, 299). <b>Female</b>. 8.8–9.6 mm long. Coloured as for male (Figs 280, 281) with these exceptions: pronotum lacking any median darker markings (irregularities in colour attributed to underlying muscles), MN very pale in ½, MS with wider median dark band in 1/2, very pale brown along the basal ¼ of suture from posterior margin of MS, small brown area at base of elytra between bases of interstitial lines 1 and 2 in 1/2; V6 with yellowish LO, V7, 8 brownish yellow, semitransparent; posterior margin of V7 broadly emarginated, posterolateral corners rounded, anterolateral areas slightly depressed; median posterior margin of V8 narrowly emarginate, with a shallow slightly depressed groove along its length in 1/2; lateral margins of T8 converge posteriorly, posterior margin straight. <b>Larva.</b> Not associated. <b>Etymology</b>. The specific name, the type locality, is considered as a noun in apposition.
