(Figs. 1–9, 19, 22)
Description. Color. Body brown; antennae reddish brown to blackish brown, first segment with a broad pale medial annulation; head above (except brown medial longitudinal stripe of vertex), spines of head dorsally black; two sides of head, meso- and metapleura brown; head beneath, anterior pronotal lobe, propleural episternum light yellowish brown; rostrum, posterior pronotal lobe and propleural epimeron dark yellow; apical rostral segment suffused with reddish brown; humeral spines and posterolateral margins of pronotum with brown suffusion; scutellum dark brown to black, apex brown; membrane of hemelytron with metallic shiny; fore femora (except dark portion) reddish brown to brown; apical 1/3 of fore femora, spines and bulging portion on fore femora dark reddish brown to black; fore tibia yellowish brown; mid and hind legs (except apical portion of femora and basal portion of tibiae) pale yellowish brown; apical portions of mid and hind femora, basal portion of tibiae dark brown; ventral surface of abdomen, connexival segments of abdomen, yellowish; pygophore brown with a pale median longitudinal stripe.
Structure. First antennal segment sparsely beset with scattered oblique setae, second segment with dense short setae, two last segments densely pubescent; legs clothed with thin long pale setae, undersurface of femora and fore tibiae with dense short setae, particularly on fore leg; apical portion of tibia with dense, oblique, short setae; propleuron episternum, sides of head, scutellum, basal portion of corium clothed with short bent setae. Head dorsally with four spines before transverse constriction and with two short, conical spines behind ocelli; first rostral segment extending much beyond posterior margin of eyes; interocellar space about 3 times as long as distance between ocellus and ipsilateral eye. Anterior pronotal lobe bulging, posterior portion of anterior pronotal lobe feebly elevated on both sides of median longitudinal sulcus, elevation with an apical tubercle; anterior half of posterior pronotal lobe feebly concave in middle; lateral pronotal spines short; posterior angles protruded; posterior margin slightly convex. Fore femora with several spines on underside (Figs. 1, 22). Hemelytron slightly surpassing abdominal tip. Pygophore oblong, median pygophore process broad and rounded, produced posteriorly; venter of paramere with few setae subapically; basal plate bridge of phallus long, nearly straight, thin; basal plate slightly thicken; phallosoma oval; dorsal phallothecal sclerite as in Figs. 7, 8, middle part concave, apical portion broad and rounded; struts long, fused basally, but widely separated for most of their length, apices supporting basal part of dorsal phallothecal sclerite; apical half of endosoma with about 28 large triangular processes (Figs. 7, 9).

Type material. Holotype: ɗ, Papua New Guinea, Madang Province, Baiteta, FOG AR 48, 1-V-1996, Olivier Missa leg. Paratypes: 1 ɗ, 1 Ψ, Papua New Guinea, Madang Province, Baiteta, FOG AR 30, 14-VII- 1995, Olivier Missa leg; paratype, 1 ɗ, Papua New Guinea, Madang Province, Baiteta, FOG AR 56, 7-VI- 1996, Olivier Missa leg.
Distribution. Papua New Guinea (Madang).
Etymology. The species is named in honor of Dr. P. H. van Doesburg of Leiden Museum for his great contribution to the study of Heteroptera and kind help in many ways in our study of Reduviidae .
Remarks. All the specimens have been caught by fogging in the canopy. AR30 refers to a tree of an unidentified species of the genus Neonauclea (Rubiaceae) . Other trees (AR48 and AR 56) have not been identified. The new species is very similar to Elemacoris vittatus Miller , but the two species can be distinguished with the key above.
