Papuandra gressitti sp. nov.

( Fig. 3 , 87 , 143 , 227 , 270 , 331 , 390 , 391 )

Etymology. The name honors Dr. Jadson Linsley Gressitt, who devoted his life to entomological work in the Pacific and Oriental Regions.

Type-material. Holotype M, from PAPUA NEW GUINEA, Morobe: Yamap , V.1986, local coll. ( EELE) . Paratype (M), as follows: PAPUA NEW GUINEA, East Highland: Okapa, M, X.1999, [no collector indicated] (ZKCO).

Description. Integument dark-brown; almost all dorsal surface of head, mandibles, basal antennomeres, margins of pronotum, suture and elytral margins, blackish; elytra brown.

Male ( Fig. 390 ). Dorsal surface of head, on gibbosities, with punctures barely fine and abundant, coarse and sparse at central area between gibbosities and occiput, and clearly coarser and more abundant laterally; area behind eyes moderately coarsely, abundantly punctate; gibbosities well defined, separated by furrow relatively shallow, and finely and sparsely punctate; ocular carina wide, elevated, with bifurcation in “Y”, close to posterior edge of eyes, indicated. Eyes ( Fig. 87 ) small and narrow; posterior ocular edge ( Fig. 390 ) distinct. Central area of clypeus oblique. Central projection of labrum ( Fig. 3 ) wide, rounded. Submentum barely depressed; punctation very coarse, abundant, in part confluent; pilosity short, sparse; anterior margin wide, elevated, mainly laterally. Mandibles ( Fig. 143 ) sub-falciform; inner margin with one tooth large at apical third; dorsal carina strongly elevated. Ventral sensorial area of antennomeres III-XI divided by carina, slightly visible from side at antennomeres IX-X ( Fig. 227 ), and more evident at antennomere XI; dorsal sensorial area of antennomere XI small, elliptical, well delimited.

Pronotum finely, sparsely punctate at central region, gradually coarser and more abundant laterally; anterior edge barely concave centrally; anterior angles very slightly projected forwards; posterior angles well defined and almost at right angles. Basal two-thirds of elytra finely, sparsely punctate near suture, gradually coarser and more abundant laterally; apical third fine and sparse (finer and more abundant close to apex). Metasternum coarsely, abundantly punctate close to metepisterna, and gradually finer and sparser towards metasternal suture. Metafemur ( Fig. 391 ) short and moderately enlarged. Dorsal face of metatibiae flat on basal two-thirds, and sulcate on apical third. Metatarsomere V (without claws) longer than I-III together ( Fig. 270 ).

Variability. Almost all dorsal surface of head dark-brown; elytra dark-brown; dorsal surface of head, on gibbosities, finely, sparsely punctate; punctation of dorsal surface of head moderately fine and sparse at area behind gibbosities; punctation of area behind eyes slightly concentrated; submentum coarsely, shallowly not abundantly punctate; inner margin of mandibles with two large teeth, together protracted, and almost completely fused until apex; lateral punctures of pronotum very similar to that of central region, in concentration and in form; anterior edge of pronotum not concave centrally.

Dimensions in mm (M). Total length (including mandibles), 20.9-23.0; prothorax: length, 4.5-5.1; anterior width, 5.7-6.3; posterior width, 5.0-5.2; humeral width, 5.5-6.2; elytral length, 11.0-12.4.

Comments. The male of Papuandra gressitti differs from P. araucariae , mainly by the sub-falciform mandibles ( Fig. 143 ), while in P. araucariae , the mandibles are not falciform ( Fig. 141 ). Differs from P. weigeli and P. queenslandensis by the ventral sensorial areas of antennomeres III-XI divided by carina (not divided in both species).
