Pandanagraecia bifurcata n. sp.

( Figs. 12 F–I; 13D, H)

Type locality. PAPUA NEW GUINEA: Southern Highlands, Muller Range, Apalu Reke (5°29'9.2''S, 142°18'7.4''E), 2867 m, 18.ix.2009, coll. P. Naskrecki—male holotype ( ANSP)

General. General characteristics as described above; brachypterous ( Fig. 13 D) (female unknown).

Wings. Tegmen strongly reduced, not reaching posterior margin of first abdominal tergite. Stridulatory file weakly bent, flat, 1.3 mm long, 0.11 mm wide, with 86 teeth.

Abdomen. Tenth tergite shallowly incised apically, with short, widely separated, rounded posterior lobes ( Fig. 12 F). Cercus slender, evenly curved inwards; its apex thickened, bifurcated into short, thick spines ( Fig. 12 G); apex of cercus slightly bent downwards when seen from side ( Fig. 12 H); epiproct unmodified, triangular. Phallus with weakly developed, paired, slender titillator, its apex narrowly acute ( Fig. 12 I). Subgenital plate strongly enlarged and flattened laterally, its apical half hook-like when seen from side, its apex pointed, slightly extending above posterior margin of 10th tergite ( Fig. 12 H); styli absent.

Coloration. Coloration red- brown ( Fig. 13 D); face with wide, dark brown vertical band, its lateral margins diffused ( Fig. 13 H); pronotum with poorly defined, darker patches in prozona and metazona; abdominal terga without markings.

Measurements (2 males). body w/wings: 22–24 (23±1.4); pronotum: 7–7.3 (7.2±.2); tegmen: 4–5 (4.5±.7); hind femur: 13.5–14.8 (14.2±.9) mm.

Material examined (3 specimens). Papua New Guinea: Southern Highlands, Muller Range, Apalu Reke, elev. 2867 m (5°29'9.2''S, 142°18'7.4''E), 18.ix.2009, coll. P. Naskrecki— 2 males (holotype and paratype), 1 nymph male ( ANSP, MCZ).

Etymology. Named in reference to the characteristically bifurcated apex of the male cercus.
