description: <i>Parahabetia pictifrons obtusa</i> ssp. nov. Figs 21E–G, 22I, 23E–I, 24A–D, Map 1(po). <b>Holotype (male):</b> Papua New Guinea: Morobe, Bulolo Gorge, McAdam Peak, (7°16’S, 146°38’E), 28.viii.1981, leg. G.K. Morris —depository: Naturalis Biodiversity Center, Leiden (NBC). Other specimens studied: same data as holotype— 1 female, 1 male paratypes (NBC). <b>Diagnosis.</b> <i>P. p. obtusa</i> <b>ssp. nov.</b> differs from the nominate subspecies, <i>P. p. pictifrons</i>, by the male tenth abdominal tergite that has the apical area divided into two long triangular extensions instead of short lobes and the three internal projections of the male cerci differ in detail as shown in Figs 21E–F compared to Fig. 21H: the first projection inserts closer to the base of the cercus but farther away from the second process and the apical swelling of the cercus is smaller. From the subspecies <i>P. p. acuta</i> <b>ssp. nov.</b>, the new subspecies differs by the apical projections of the tenth abdominal tergite that are at end little downcurved and with obtuse tip instead of being sub-straight and with acute tip. The male cerci differ in detail between both subspecies as shown in Fig. 21F compared to Fig. 21C. The stridulatory file on the underside of the left tegmen in <i>P. p. obtusa</i> is shorter than in <i>P. p. acuta</i> with less numerous teeth. The male titillators are similar in both subspecies but more strongly curved between basal and apical area in <i>P. p. obtusa</i> and the apical area is wider than in <i>P. p. acuta</i>. <b>Description.</b> Femora with the following number of spines on ventral margins: (1) a 6–7, p 8; (2) a 7–8, p 3–4; (3) a 10–12, p 12–20 (n=3). Male. Stridulatory file on underside of left tegmen 1.39 mm long with about 154 teeth: 25 teeth at curved base; 67 large teeth around mid-length; 62 teeth after step becoming white and indiscernible narrow toward end (Fig. 22I). Tenth abdominal tergite domed with medial furrow; apical area dorso-ventrally compressed and terminating into a pair of markedly spaced, elongate lobes with obtuse tip (Fig. 21E). Cerci elongate and narrow, curved around midlength, with three dorso-internal projections: the basal projection with a curved stem with globular end that carries a minute spinule, the second projection narrow, compressed and slightly curved, the third projection forming a short spine at base of the globularly swollen end of cercus (Fig. 21F). Subgenital plate above bases of styli with narrow projections that are longer than the styli and at end faintly out-curved (Figs 21E, 21G). Titillators with about basal half curved laterally and vaulted with convex distal and concave proximal surface, in roughly mid-length bent and apical half little widening towards end, at distal end swollen and with a lamellar crest at external side (Figs 21E–G). The lamellar crests are in situ the posterior ends of the titillators (Fig. 23I). Female. Subgenital plate in central and apical areas flattened and divided along mid-line by a furrow that is bordered on both sides by carinae that are, behind mid-length, deviating from each other, do not reach the end of the subgenital plate, and are connected by a thin septum that also forms the pair of obtuse apical lobes; both halves of the subgenital plate are standing angularly to each other and have the lateral areas occupied by a large oval swelling; central area and lateral swellings with smooth surface, a broad band along apical margin coarse (Figs 24A, C). Ovipositor upcurved, the ventral margin markedly stronger curved than the dorsal margin; dorsal margin in apical area slightly re-curved and faintly concave before acute tip (Fig. 24B). Measurements (2 males, 1 female).—Body w/o wings: male 21.0–21.5, female 27; pronotum: male 6.3–6.5, female 6.2; tegmen: male 18.5–19.0, female 20.5; hind femur: male 14.5, female 14.5; ovipositor length: female 12.5 mm. <b>Etymology.</b> The name of the new species refers to the shape of the obtuse apical lobes of the male tenth abdominal tergite; from Latin <i>obtusus, obtusa</i> = obtuse, blunted.
