( Fig. 4 )

Type material. HOLOTYPE: ♀, ‘ Sulawesi Utara, Gumung Moat (1100 m a.s.1.), Station: 063, 29.X.1985, Project Wallace, R. Bosmans & J. van Stalle leg.’ ( ISNB).

Description. Female. Head, antennae (except last antennomere), pronotal collar, membrane, and legs black. Antennomere IV whitish, only narrow bands on its base and apex black. Labium blackish brown, last segment whitish. Pronotum pale yellow, pronotal protuberances and adjacent areas on pronotal lobe with orange tinge. Callar lobe posteromedially and posterolateromedially, and punctured part of pronotal lobe, i.e. medial and lateromedial areas, dark; medial keel connecting callar and pronotal lobes pale. Scutellum black, apex pale. Clavus black, only anal vein and claval commissure very narrowly red. Corium light red with medial oval spot not exceeding medial cleft, its inner side with black band running from spot towards base of corium, reaching level of distal third of scutellum and separated from black clavus by very thin red line. Mesotergites IV-VII black, discs partially paler reddish. Mesotergites II-III and dorsal and ventral laterotergites along entire length yellow. Pronotal epipleuron on ventral side and upper part of posterior pleural flange I yellowish to orange. Sternum and abdomen dark leathery brown, epicoxal lobes and coxae somewhat paler.

Head wide, rather short. Antennae thick. Labium reaching between middle coxae. Callar lobe weakly convex, pronotal lobe flat, humeral protuberances elevated. Lateral margin of pronotum almost horizontal, medially slightly sinuate. Callar and pronotal lobes more convex in their wide lateral zones than in their medial parts. More than half of scutellum with rather deep depression. Outer margin of corium from level of claval apex more convex; distal part of corium rounded on outer side but apex with obtuse point, distal margin rather long, inclined towards outer side, basal two thirds straight, slightly bent outwards on its distal third. Membrane almost crescent-shaped. Hemelytra covering dorsal gland opening between tergites IV and V. Lateral margin of abdomen convex in distal part.

Callar lobe laterally almost without punctures, punctures on pronotal lobe rather small, lateral margins of pronotal lobe with broad zone without punctures. Scutellum and clavus with distinct punctures, corium with smaller and scarcer punctures in basal part (up to black spot) and on outer side up to median vein. Punctures behind median vein small and concolorous, absent towards apex of corium. Body pubescence whitish, including that on visible mesotergites. Measurements (mm). Holotype female. Body length: 7.72. Head: width (including eyes) 1.40, interocular width 0.92. Antenna: antennomere I 1.30, antennomere II 1.16, antennomere III 0.78, antennomere IV 1.54. Pronotum: length 1.30, width 2.38. Scutellum: length 1.13, width 1.24. Corium: length 3.83, width 1.51.

Differential diagnosis. Delacampius subtilepunctatus sp. nov. differs from D. grossepunctatus sp. nov. by its narrower head, shape of the pronotum (narrower in its anterior part rather than almost quadratic, lateral margin anteriorly less conspicuous and in the middle less sinuate), less convex callar lobe, longer corium covering only the dorsal gland opening between tergites IV and V, crescent-shaped membrane (very rudimentary in D. grossepunctatus sp. nov.), medial spot on the corium not exceeding the medial cleft (reaching up to the costal margin in D. grossepunctatus sp. nov.), almost complete lack of conspicuous black puncturation bordering the lateral margin of the callar lobe, and finally by finer puncturation on the pronotal lobe, which also does not reach the lateral margin whereas the punctures in places of light coloration are concolorous and almost missing in the apical part (coarse and black in D. grossepunctatus sp. nov.). The new species differs from other brachypterous species of the genus by the characters given in the diagnosis of D. grossepunctatus sp. nov.

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

Distribution. Indonesia (Sulawesi).
