Figs. 18 , 19, 20 , 81 . Remarks. P. wolfi Berchmans, 1925 was designated as a junior synonym of P. rosenbergii Vollenhoven, 1871 by Breuning (1944) and also assumed to be a synonym by De Jong (1947) , but not formalized. Examined type specimen. HT ♀ ZMA (photo examination), BL = 46.0 mm, Papua New Guinea , Madang (formerly Alexishafen), 1911, leg. P. R. Niedurny. Other examined specimens: 1♂ CUN, BL = 42.1 mm , Papua New Guinea , Morobe Province (MP), Bulolo, Mauki Range, 1997.09.0 9, leg. M. Hudson; 1♂ CUN, BL = 41.0 mm, Papua New Guinea , MP, Aseki, Hiewini Village, 1998.03.27, leg. M. Hudson; 1♀ CUN, BL = 46.0 mm, Papua New Guinea , MP, Aseki, Yeva Village, 1997.06.19, leg. M. Hudson. Morphological characteristics. a large and broad species ( BL = 41.0–46.0 mm) with body approximately 2.9 x longer than wide ( Figs. 18–19 ). Antennae: of medium length in both sexes, extending beyond apices by about 4 antennomeres. Thorax: pronotum with an elongated dark brown patch medially surrounded by dense whitish pubescence mixed with orange to light brown pubescence. There are two tiny almost oblique tubercles medially on pronotum, remaining surface of pronotum flat. Elytra: with two white transverse bands or spots from apices, remaining part of elytra light brown. Surface is flattened with very small granules ( Fig. 18–20 ). The slightly elevated and transverse ridge on the middle of elytra is very weak. Venter: Prosternal process with a large and pointing tubercle anteriorly. Mesosternum, and abdominal ventrites, weakly mottled with a mixture of short brownish and greyish pubescence. Remarks. This rarely collected species is characterized by the unique color patterns on pronotum and elytra. The HT is missing the pronotum, but the white lateral spots on elytra shows that it truly belongs to P. wolfi sp. res. The species has only been found in Papua New Guinea , near the northern coast and in the mountains in the Morobe Province ( Fig. 81 ).
