Melanesiandra bougainvillensis sp. nov.

( Fig. 26, 27 , 84 , 138, 139 , 224 , 267 , 329 , 382-384 )

Etymology. The name refers to the island of Bougainville in the Solomon Islands.

Type material. Holotype M, from Papua new guinea, Autonomous Region of Bougainville : Bougainville Island (Kukugai Village; 150 m), X.1960, W. W. Brandt coll. ( BPBM) . Paratypes (4 F), as follows: Papua new guinea, Autonomous Region of Bougainville: Bougainville Island ( Kukugai Village ; 150 m), F, X.1960, W. W. Brandt coll. ( MZSP) ; F, XII.1960, W. W. Brandt coll. ( BPBM). SOLOMON ISLANDS, Makira-Ulawa Province: San Cristobal Island ( Wugiroga ), F, 8.VIII.1960, C. W. O’Brien coll. ( BPBM). Isabel Province: Santa Isabel Island (Molao), F (paratype of Parandra solomonensis Arigony ), VI.29.1960, C. W. O’Brien coll. ( BPBM) .

Description. Integument shining, brown; anterior edge of head, parts of mandibles, lateral edges of pronotum and of scutellum, and elytral suture blackish or dark-brown.

Male ( Fig. 382 ). Head wide, proportionally very large in relation to body size; gibbosities of dorsal surface with punctures coarse, abundant and not confluent; area between gibbosities and ocular carina with depression well defined, and with punctures coarse and very sparse; area behind eyes with punctures very coarse, abundant, in part confluent. Central region of clypeus strongly oblique. Central projection of labrum ( Fig. 26 ) distinct, moderately narrow and barely rounded at apex. Eyes ( Fig. 84 ) emarginate. Mandibles of males ( Fig. 138 ) sub- falciform, shorter than head; inner margin with two teeth together protracted. Submentum glabrous, not clearly delimited by fine suture; surface with coarse punctation, very sparse in central region, in part confluent laterally; margin close to mentum wide and slightly elevated. Antennae not notably short (reaching the pronotal base); ventral sensorial area of antennae not visible from side ( Fig. 224 ), except on apical half of antennomere XI; antennomeres III-X not divided by carina; apical half of antennomere XI divide by carina; dorsal sensorial area of antennomere XI small.

Pronotum convex; punctation fine and sparse on disc, gradually coarser laterally (mainly towards anterior angles); anterior margin almost in a straight line; anterior angles projecting forward; lateral angles absent; posterior angles sub-rounded. Elytra with punctures barely coarse and abundant, finer and more abundant on apical third; elytral carinae absent. Metasternum with some punctures, coarse, laterally. Metafemur ( Fig. 383 ) moderately short. Metatarsus (without claws) ( Fig. 267 ) approximately as long as metatibia (without apical spines); metatarsomere V longer than I-III together.

Female ( Fig. 384 ). Eyes large. Apex of central projection of labrum ( Fig. 27 ) narrow, acute or subacute. Ventral sensorial area of apical antennomeres variable, but not distinctly divided by carina at basal third or forth of the segments: divided from antennomere VII; or divided only at antennomere XI. Mandibles as in Fig. 139 .

Dimensions in mm (M / F). Total length (including mandibles), 13.9/16.0-17.6; prothorax: length, 3.0/ 3.3-3.7; anterior width, 3.7/3.9-4.3; posterior width, 3.1/3.3-4.0; humeral width, 3.7/4.3-5.0; elytral length, 8.0/9.9-10.8.

Comments. Melanesiandra bougainvillensis ( Fig. 382, 384 ) is similar to M. solomonensis ( Fig. 379, 381 ), but differs, principally, by the clypeus-labrum not strongly convex at middle and absence of a small projection on each side of the central projection of labrum.
