Pandanagraecia stylata n. sp.

( Figs. 12 A–E; 13A, G, I, L, N)

Type locality. PAPUA NEW GUINEA: Western Province, Muller Range, Gugusu (5°43'45.3''S, 142°15'47.8''E), 515 m, 3–10.ix.2009, coll. P. Naskrecki & D.C.F. Rentz—male holotype ( ANSP)

General. General characteristics as described above; macropterous ( Fig. 13 A).

Wings. Tegmen fully developed, reaching or slightly surpassing apex of abdomen, but not reaching apex of hind tibia ( Fig. 13 A); anterior margin straight; apex narrowly rounded. Veins Sc, Rn and M straight, nearly parallel, only slightly divergent towards apex; Rs very short, branching off near apex. Stridulatory file nearly straight, flat, 1.4 mm long, 0.14 mm wide, with 120 teeth.

Abdomen. Tenth tergite with small, narrowly elliptical incision, posterior lobes narrowly triangular ( Fig. 12 A). Cercus long, slender, evenly curved inwards; its apex slightly expanded dorso-ventrally, distinctly curved inwards, and with small, ventral subapical lobe ( Fig. 12 B). Phallus with weakly developed, paired, slender titillator, its apex narrowly acute ( Fig. 12 E). Subgenital plate strongly flattened laterally in posterior half, narrow at base, expanded towards apex ( Fig. 12 C); posterior surface of expanded part of subgenital plate with semicircular groove, its edges with small, dark spines; styli reduced, but distinctly noticeable, about twice as long as wide ( Fig. 12 D). Female subgenital plate about as long as wide, with small, triangular incision; posterior lobes acute ( Fig. 13 I).

Coloration. Coloration light brown ( Fig. 13 A); face with sharply defined, black vertical band ( Fig. 13 G); pronotum with poorly defined, darker patches in prozona and metazona; abdominal terga without markings. Wings with venation in costal field yellow, spaces between veins dark brown.

Measurements (1 male, 6 females). body w/wings: male 24, female 34–41.5 (38.1±3.1); body w/o wings: male 24, female 25–29 (26.8±1.9); pronotum: male 7, female 7–8 (7.7±.4); tegmen: male 15, female 16–18 (17.1±.9); hind femur: male 15.5, female 17–20 (18.4±1); ovipositor: 17–18 (17.6±.5) mm.

Material examined (9 specimens). Papua New Guinea: Western Province, Muller Range, Gugusu , elev. 515 m (5°43'45.3''S, 142°15'47.8''E), 3–10.ix.2009, coll. P. Naskrecki & D.C.F. Rentz— 1 male, 7 females (holotype, paratypes) ( ANSP, MCZ); Muller Range, Sawetau , elev. 1550–1700 m (5°39'23.7''S, 142°18'16.5''E), 11–17.ix.2009, coll. P. Naskrecki & D.C.F. Rentz—1 nymph male ( MCZ).

Etymology. Named in reference to the presence of clearly visible styli on the subgenital plate of the male.
