Figs. 29, 30 , 31 , 63, 64, 65, 66 , 81 .

Examined type specimens. HT ♂ ZMA (photo examination), BL = 55.0 mm, BW = 17.5 mm, Indonesia, Papua, Etna Bay (near Jayapura), 1905/1906 (New Guinea Expedition); PT ♀ ZMA (photo examination), BL = 51.0 mm, Indonesia, Papua, Sabang, 1907-07, leg. H.A. Lorentz; PT ♀ ZMA (photo examination), BL = 44.0 mm, Indonesia, Papua, Merauke, 1904/1905 (New Guinea Expedition);

Other specimens examined. Indonesia: 1♀ CUN, BL = 45.0 mm, Papua (Irian Jaya), Sorong, 2001, leg. P. Suhanda; 1♂ CUN, BL = 41.0 mm, Papua (Irian Jaya), Sorong, 2005, leg. P. Suhanda; 1♂ CHW, BL = 41.0 mm, Papua, Timika, 2002.09; 1♂ CHW, BL = 40.0 mm, Papua, Timika, 2004.06.

Morphological characteristics: a large and slender species ( BL = 40.0–55.0) with body approximately 3.2 x longer than wide ( Figs. 29, 30 ). Antennae: relatively long in females and very long in males, extending beyond apices by about 4–5 antennomeres in females and by about six antennomeres in males. Thorax: pronotum with a longitudinal, yellowish and narrow band interrupted medially with a dark brown spot. Pronotum is densely granulated apically and below the broadened base at each lateral spine. Pronotum with two tiny tubercles medially. Elytra: sub-parallel, strongly narrowing towards apices in males, but weakly narrowing towards apices in females, with small spines scattered on the entire surface in both sexes. The colour is dark brown with two transverse and oblique, grey bands on elytra ( Figs. 29, 30 ). Lateral carina on elytra with a series of large granules ( Figs. 29–31 ). Humeral spine in males extended and pointing forward. Legs: strongly mottled with white and brown pubescence.

Venter: brown and extensively mottled with grey and dark brown pubescence, prosternal process with a large and strongly pointing tubercle anteriorly. Mesosternum and abdominal ventrites are extensively mottled with a mixture of short brownish and greyish pubescence. Male genitalia: aedeagus is about 12.0 mm long, weakly curved towards apex and compressed dorso-ventrally ( Fig. 63 ), dorsal surface smooth and shining ( Fig. 64 ). Parameres are about 3.0 mm long, fine and strongly narrowing towards apices. The inner margins well separated and diverging towards apices, with relatively long setae dorsally and ventrally, surface dorsally smooth, and the projection at base (between the two parameres) blunt ( Fig. 65 ). Tergite VIII (about 3.5 mm long) relatively large and rounded with a posterior margin concave in the middle and covered with relatively fine and short setae ( Fig. 66 ). The colour of male genitalia is brownish.

Remarks. This species is most similar to P. sepicanus , but easily separated by the extensively mottled ventral surface with a mixture of brownish and greyish pubescence, the extended humeral spine, and the two oblique, grey bands on elytra. P. ennevei has, so far, only been found in Indonesia, in the western parts of the island of New Guinea ( Fig. 81 ).
