( Figs 10 E-J; 11G-N)

TYPE MATERIAL. — Holotype: Vanuatu. [Sanma province], Espiritu Santo [Island]. Butmas , grotte de Fapon, 15°19’51.6”S, 166°57’53.6”E, jour, paroi proche de l’entrée, 15.X.2006, L. Desutter-Grandcolas, 1 ♀ (fn 15) (MNHN-ENSIF2121).

ETYMOLOGY. — Species named after the type locality.

DIAGNOSIS. — Species close to P.offensa and P.pentecotensis n. sp. It can be separate from P.offensa by its larger size,

its much lighter colouration and the ornamentation of its ovipositor, and from P. pentecotensis n. sp. by its colouration, genitalia and ovipositor ornamentation. Male unknown.

DESCRIPTION

Size and global shape, as well as head (including eyes, fastigium, ocelli, palpi), pronotum shape and legs as in P. pentecotensis n. sp. (see above).TIII serrulation: no spine between tibia apex and subapical spur 1, 2 between subapical spurs 1 and 2, 2 or 3 between subapical spurs 2 and 3, 3 between subapical spurs 3 and 4, and 2 inner and 5 or 6 outer teeth above subapical spur 4. Basitarsi III with 7 very small spines on outer margin.

Colouration

Fastigium light yellow; ocelli all circled with black. Head dorsum light yellow, with the same 4 brown lines as in P. pentecotensis n. sp., but the median lines fused; a wider brown line behind each eye, not connected to brown spots of the cheek ( Fig. 10H ). Face light brown; a pair of thin, longitudinal brown lines, prolonging laterally the dark colouration around the median ocellus; a pair of dark, submedian spots along the epistemal suture; and a brown, oblique line from the lower angle of each eye getting thinner toward the inner angle of the mandibles ( Fig. 10G ). Scapes light yellow, the anterior side with a basal ochre spot and an apical brown spot, the two separate by a small, ivory-coloured area. Mouthparts light yellow, except for two short brown lines on clypeus. Antennae brown over their whole length. Pronotum brown with well-defined yellow patterns on both dorsal disc ( Fig. 10I ) and lateral lobes ( Fig. 10J ).

Male

Unknown. Female

FW venation very similar to that of P. pentecotensis n. sp., with 10 longitudinal veins on dorsal field and slight differences in CuP bifurcations (compare Fig. 11A with Fig. 11G ). FWs whitish, transparent, with numerous, very short, dark brown setae, and yellowish veins surrounded with brown; lateral field transparent with dark brown veins. Subgenital plate wider than long, its posterior margin concave ( Fig. 11I ). Ovipositor as short as in P. pentecotensis n. sp.; ornamentation of valve apex similar to that of P. pentecotensis n. sp., but the teeth of ventral valves much higher and narrower, and the large teeth of dorsal valves located before lanceolate valve apex much bigger ( Fig. 11M, N ).

Female genitalia. Copulatory papilla broadly conical in shape, narrowed before mid line; entirely sclerotized, except for gonopore area on ventral side; posteriorly to gonopore, a pair of sclerotized, longitudinal crests ( Fig. 11 J-L).
