Pandanagraecia armata n. sp.

( Figs. 12 N–Q; 13B, F)

Type locality. PAPUA NEW GUINEA: Western Province, Muller Range, Sawetau (5°39'23.7''S, 142°18'16.5''E), 1550–1700 m, 11–17.ix.2009, coll. P. Naskrecki & D.C.F. Rentz—male holotype ( ANSP) General. General characteristics as described above; brachypterous ( Fig. 13 B) (female unknown). Wings. Tegmen strongly reduced, not reaching posterior margin of first abdominal tergite. Stridulatory file weakly sinuous, flat, 1.33 mm long, 0.09 mm wide, with 190 teeth.

Abdomen. Tenth tergite with deep, narrowly triangular incision, posterior lobes long, narrowly rounded apically ( Fig. 12 N). Cercus robust, straight ( Fig. 12 O), with long, dorsal subapical spine; shorter, ventral subapical one; and very short, ventral apical one ( Fig. 12 P). Epiproct unmodified, triangular. Phallus with weakly developed, paired, slender titillator, its apex narrowly acute ( Fig. 12 Q). Subgenital plate strongly flattened laterally in posterior third, its apical part hook-like when seen from side ( Fig. 12 P); its apex pointed, bent backwards and fitting into incision of posterior margin of 10th tergite ( Fig. 12 N); styli reduced to minute, barely discernible knobs.

Coloration. Coloration red- brown ( Fig. 13 B); face with wide, dark brown vertical band ( Fig. 13 F); pronotum with poorly defined, darker patches in prozona and metazona; abdominal terga without markings.

Measurements (1 male). body w/wings: 23; pronotum: 6.5; tegmen: 3.3; hind femur: 16 mm.

Material examined. The holotype is unique.

Etymology. Named in reference to the pronounced armature of the cercus.
