INDONESIA: West Papua: Manokwari

Etymology. -

The species is named after the type locality Manokwari; noun in apposition.

Diagnosis. -

This new species differs from all congeners by lighter coloration, including pronotal disk yellow brown with sparse red brown patterns, and shape of male genitalia. Among species group, R. manokwari sp. nov. differs by male genitalia with pseudepiphallus indented dorsally at base of apical region and tapering to a narrower apex. This species has similar pale coloration as R. biakis sp. nov. but differs by absence of longitudinal median stripe in the pronotal disk and by shape of male genitalia.

Description. -

Size average for the genus (Fig. 17 View Figure 17 ). Dorsum of head yellow brown with five well-separated red brown longitudinal bands, middle one corresponding to incomplete fusion of two bands (Fig. 4F View Figure 4 ). Fastigium yellow brown with red brown patterns. Scapes yellow brown with dark patterns. Antennae yellow basally, distally brown with pale yellow rings. Fastigium verticis black with a yellow cross-shaped pattern; frons dark brown to black with two lateral yellow spots, black beneath scapes; clypeus and mouthparts black dorsally, pale yellow ventrally (Fig. 5F View Figure 5 ). Head lateral side red brown, genae slightly lighter with a triangular pale spot. Pronotal disk yellow brown mottled with dark brown (Fig. 4F View Figure 4 ). Lateral lobes of pronotum distinctly darker than disk, dark red brown, with a paler stripe near ventral margin (Fig. 6F View Figure 6 ). FIs and FIIs mostly cream-colored with a few well-defined brown spots, knee areas brown; TIs and TIIs dark brown with a cream-colored ring in middle. FIIIs yellow brown, knees brown. Tergites unicolorous brown.

Male. FW reaching base of fourth abdominal tergite. FW coloration (Fig. 7F View Figure 7 ): Cells and veins of dorsal field mostly brown; area between M and R creamed-colored; basal area with a cream-colored spot on external corner. Lateral field red brown, with ventral region more yellow brown. FW venation typical of genus; 1A slightly bisinuate anterior to angle; oblique vein bifurcated, posterior branch slightly sinuous. Apex of dorsal field rounded; apical parts of its longitudinal veins very strong. Apical field reduced, including few cells of E alignment only.

Male genitalia: (Figs 8F View Figure 8 , 15E View Figure 15 , 15F View Figure 15 ). Pseudepiphallus triangular, its basal margin slightly indented in the middle, basal third much wider, lateral margins indented and tapering to a narrower apical third, elongate as characteristic of the species group. Apical third narrowed in dorsal view, slightly concave dorsally, tapering into a narrow posterior apex; slightly truncated and indented apically. Rami short, slightly shorter than half of pseudepiphallus length, slightly diverging anteriorly. Pseudepiphallic parameres stout, not bent in middle, apical half finger-like with subacute apex. Ectophallic apodemes parallel and long, surpassing beyond anterior margin of pseudepiphallic sclerite. Endophallic sclerite with anterior region short and barely reaching anterior margin of pseudepiphallic sclerite, with posterior lateral arms tongue-shaped and slightly longer than median expansion.

Female. FW reaching middle of second tergite, with an apical indistinct cream-colored spot (Fig. 9E View Figure 9 ).

Female genitalia: Ovipositor shorter than FIII. Copulatory papilla conical, smaller and stout; apex folded ventrally, short, pointed; dorsal face with a sclerotized area; ventro-anterior end forming an oval to pyriform rim (Fig. 10E View Figure 10 ).
