Pandanagraecia porgera n. sp.

( Figs. 12 J–M; 13C, E, J, K, M)

Type locality. PAPUA NEW GUINEA: Enga, Porgera camp (5°29'3.5''S, 143°8'8.8''E), 2336 m, 15.ix.2009, coll. D.C.F. Rentz—male holotype ( ANSP)

General. General characteristics as described above; brachypterous ( Fig. 13 C, M).

Wings. Tegmen strongly reduced, not reaching posterior margin of first abdominal tergite ( Fig. 13 C). Stridulatory file flat, straight, 1.0 mm long, 0.1 mm wide, with 90 teeth; hind wing extremely reduced. Female tegmina shorter than half of pronotum, overlapping.

Abdomen. Tenth tergite deeply incised apically, with rounded, widely separated posterior lobes ( Fig. 12 J). Cercus relatively robust, evenly curved inwards; its apex thickened, truncate, with small subapical lobe ( Fig. 12 K); apex of cercus slightly bent upwards when seen from side ( Fig. 12 L); epiproct unmodified, triangular. Phallus with weakly developed, paired, slender titillator, its apex narrowly acute ( Fig. 12 M). Subgenital plate strongly enlarged and flattened laterally, its apical half nearly triangular when seen from side, its apex pointed; styli absent. Female subgenital plate triangular, with small, triangular apical incision, posterior lobes triangular, somewhat rounded apically ( Fig. 13 K).

Ovipositor. Ovipositor about as long as hind femur (ratio femur/ovipositor 0.98–1.01); slender, slightly curved, apex with both valvulae smooth, apex pointed ( Fig. 13 J).

Coloration. Coloration red- to orange-brown ( Fig. 13 C); face with wide black vertical band ( Fig. 13 E); pronotum with poorly defined, darker patches in prozona and metazona; abdominal terga with darker, diffused band along mid-line.

Measurements (6 males, 3 females). body w/wings: male 21.2–24 (22.7±1.3), female 28–30 (29.3±1.2); pronotum: male 6–6.2 (6.1±.1), female 6; tegmen: male 3–3.5 (3.1±.2), female 2–3 (2.4±.5); hind femur: male 11–11.8 (11.2±.3), female 12–12.2 (12.1±.1); ovipositor: 12–12.2 (12.1±.1) mm.

Material examined (19 specimens). Papua New Guinea: Enga, Porgera camp, elev. 2336 m (5°29'3.5''S, 143°8'8.8''E), 3.ix.2009, coll. P. Naskrecki & D.C.F. Rentz— 1 female, 2 males (paratypes) ( ANSP); same locality, 15.ix.2009, coll. D.C.F. Rentz— 3 females, 8 males (incl. holotype, 10 paratypes), 2 nymph females, 3 nymph males ( ANSP, MCZ).

Etymology. Named after the type locality, Porgera mining camp in Enga Province of Papua New Guinea.
