Delacampius grossepunctatus sp. nov.

( Fig. 3 )

Type material. HOLOTYPE: ♀, ‘ Sulawesi Utara, Dumoga-Bone Nat. Park, Toraut: S. Tumpah, Station 005, X.1985, Project Wallace, R. Bosmans & J. van Stalle’ ( ISNB).

Description. Female. Head, antennae (except last antennomere) and legs, scutellum, clavus, membrane and visible tergites black. Antennomere IV white except narrow black band on base and apex. Labium yellowish white. Pronotum brownish black, callar and pronotal lobes laterally with narrow yellow band including lateral margin. Corium yellowish with large black spot extending beyond corial cleft to costal margin, and with black band running on inner side of costal margin from this spot almost to base of corium ( Fig. 3 ). Pronotal epipleuron, hypocostal lamina and dorsal and ventral laterotergites light yellow. Sternum and ventrites (except the above-mentioned parts) black.

Head wide, antennae strong. Labium exceeding hind coxae. Pronotum almost quadratic, lateral margin almost horizontal, rather conspicuously sinuate near midlength; callar lobe distinctly elevated, pronotal lobe flat, humeral protuberances not elevated. Scutellum with imprinting reaching approximately to its midlength. Hemelytra markedly shortened, not covering dorsal gland openings between tergites III-IV and IV-V. Apical part of corium strongly convex both from outer and inner side (distal margin bow-shaped). Membrane rudimentary, its hind margin horizontal, on inner side almost rectangularly bent towards apex of clavus. Abdomen wide, narrowing evenly towards apex.

Callar lobe laterally with pronounced puncturation. Pronotal lobe with very dense and coarse punctures, laterally rather close to lateral margin. Scutellar base with wide zone of finer punctures, apical part almost without punctures. Clavus and corium with coarse punctures. Conspicuous black punctures also present on parts of corium of light coloration, including area below lower margin of black medial spot. Pubescence of light colour on entire body, including visible mesotergites, here very dense.

Measurements (mm). Holotype female. Body length 7.67. Head: width (including eyes) 1.51, interocular width 1.00. Antenna: antennomere I 1.13, antennomere II 1.24, antennomere III 0.86, antennomere IV 1.46. Pronotum: length 1.51, width 2.54. Scutellum: length 1.19, width 1.51. Corium: length 3.05, width 1.51.

Differential diagnosis. This species resembles Delacampius subtilepunctatus sp. nov. but differs by a number of characters including the following: head wide and anteriorly more protruding, callar lobe more convex, humeral protruberances on pronotal lobe hardly present, corium much shorter and distally more rounded both from the outer and inner side, membrane reduced, much smaller, differently shaped and distally not covering two scent gland openings, abdomen narrowing distally at midlength laterally, puncturation on both pronotum and corium much coarser and black, labium completely pale, and medial spot exceeding corial cleft. Two other brachypterous species, D. flavipes (Tauber, 1927) and D. pilosa (Stål, 1870) , can be easily distinguished from D. grossepunctatus sp. nov. by the amber-yellow legs ( D. flavipes ) or the colour of the corium, which lacks the round black spot and has the outer half reddish and the inner half black ( D. pilosa ). In D. pyrrhocorides (Bergroth, 1894) , which occurs in New Guinea, all known specimens are macropterous; only one female specimen found on Solomon Islands (Guadalcanal Island, STEHLÍK 1965) is brachypterous. This species is smaller, its antennae are more slender, and it differs substantially by the bicolored laterotergites (laterotergites II-V red and VI-VII black).

Etymology. The specific epithet is composed of the Latin adjectives grossus (= coarse) and punctatus (= punctured).

Distribution. Indonesia (Sulawesi).
