( Figs 33–43 )

Type material. Male holotype: [New Guinea: NE. Torricelli Mts. Siaute, sea lev. XI-9–17-1958], [W.W. Brandt Collector], [ Zophiuma doreyensis (Dist.) det. R.G. Fennah] ( BPBM). Paratypes: 1♀ [ New Guinea: NE. Torricelli Mts., Nengian vill., XI-17–24-1958] [W.W. Brandt collector] ( BPBM) . 1♀ [ New Guinea: NE. Torricelli Mts., Sugoiteis vill. 900 m. II-10–28-1959] [W.W. Brandt collector Bishop] MNHN ( EH) 24623 ( MNHN), 5♂, 1♀ [ New Guinea, Torecella Mts., Afua village, 16.iii.–3.iv.1939], [G.P. Moore, B.M. 1939–479], [NHMUK 013589025–013589029] and [NHMUK 013589030] ( BMNH) .

Distribution. Mount Torricelli in Sandaun Province ( Papua New Guinea)

Diagnosis. The shape of male anal tube is characteristic. In lateral view, apical lobe is far less developed than for the three other species, its width is not greater than width measured just before epiproct insertion ( Fig. 38 ).

Description. Total length of male holotype: 2.15 cm (incl. tegmina).

Head. In dorsal view, vertex 1.33 larger than long in midline, lateral margins parallel, anterior and posterior margins regularly curved, vertex surface flat without median carina ( Fig. 33 ). In frontal view, frons 1.14 wider across widest part than long in midline, fronto-vertex margin slightly rounded and convex followed by lateral margins almost parallel on half their length then sharply curved and reaching a frontoclypeal suture concave and slightly v shaped, frons tree carinate, sublateral carinae joining dorsally and delineating an ovoid disc in middle, median carina clearly visible ( Fig. 35 ). In lateral view, ocellus present and located bellow compound eye and anteriorly to antennae. Ocellar carina present and genal carina absent ( Fig. 34 ). Prothorax larger than head and 4.6 larger than long in midline. Tegmen 3.6 longer than wide, ScP+R(+MA) and MP forking almost at same level, then CuA, all forking before end of clavus, presence of an anastomosis between CuA1 and MP(3+4) ( Fig. 34 ). Metatibiae bearing 3 lateral spines and 9 apical spines organised in a v shaped line, first metatarsal segment bearing 11 apical spines organised in a triangular area, longer than cumulative length of second and third metatarsal segment, second segment reduced to a lobe without any spine.

Male terminalia. In lateral view, anal tube thick, 2.6 times longer than its biggest thickness measured just before epiproct insertion, apical lobes not clearly developed ( Fig. 38 ). Dorsal and ventral margins of pygofer converging posteriorly, posterior margin convex. Gonostylus with dorsal margin irregular bearing a process oriented anterodorsally close to it, ventral and posterior margins roughly straight and perpendicular to each other. Dorsal periandrium developed in a dorsal extension bilobate apically, followed posteriorly by a process with a blunt tip and laterally by a structure wing shaped covering partially the two other structures, its most anterior margin developed anteriorly into two teeth ( Figs 41, 43 ). Ventral periandrium not strongly developed but with its most posterior half partially membranous which allows the structure to inflate ( Figs 37 , 43 ). Aedeagus bearing two ventral processes, PvaA long regularly curved, oriented anteriorly and blunt at tip, PvpA short, slender with a sharp apex. Apex of aedeagus developed in a bifid structure and a small tooth on side ( Figs 41–42 ).

Colour. Mostly light yellowish ( Figs 33–35 ), darker brownish zones can be observed on thorax in dorsal view and on tegmen, tips of spines on metatibia and on first metatarsal segment are dark brown. A white dot surrounded by a roundish dark brown area is located in apical area of tegmen.

Etymology. The species was collected on Mount Torricelli in the Northwest of Papua New Guinea. The species is named after this mount.
