Type locality. -
INDONESIA: West Papua: Kuala Kencana.
Etymology. -
The species is named after the type locality: Kuala Kencana; noun in apposition.
Diagnosis. -
This new species differs from all congeners by its large size, the large triangular shape of male pseudepiphalllus, and stout pseudepiphallic parameres, gently curved but not bent in middle, apex swollen and bilobate. The new species is very similar to R. maoke sp. nov. but differs by overall smaller size, male FW venation with two cell alignments in apical field (instead of one in R. maoke sp. nov.), shape of oblique vein, and male genitalia with distinctly smaller pseudepiphallus and endophallic sclerite shorter anteriorly (forming a Y-shape in R. maoke sp. nov.), with lateral arms pointing more posteriorly. The male genitalia are also similar to R. manokwari sp. nov. but differ by the absence of indentation at base of the apical third of lateral margin and shape of pseudepiphallic parameres.
Description. -
Large sized among congeners (Fig. 16 View Figure 16 ). Dorsum of head with broad red brown bands faintly to narrowly separated (Fig. 4E View Figure 4 ). Fastigium red brown (Fig. 4E View Figure 4 ). Scapes dark brown, posterior part yellow with a dark spot. Fastigium verticis and frons black, and black beneath scapes; clypeus and mouthparts pale brown with darker patterns (Fig. 5E View Figure 5 ). Pronotal disk red brown with some faint and irregular paler brown patterns (Fig. 4E View Figure 4 ). Lateral lobes slightly darker than disk, dark brown except a yellow spot on ventral margin (Fig. 6E View Figure 6 ). FIs and FIIs brown with a few dark spots near knees, TIs and TIIs dark with pale yellow rings. FIIIs brown, knees dark brown. Tergites brown, with posterior margin darker.
Male. FWs reaching apex of fourth abdominal tergite. FW coloration (Fig. 7E View Figure 7 ): Dorsal field cells and veins mostly brown; with area between M and R dark brown; basal area with a small cream-colored spot on external corner. Lateral field red brown, with ventral region more yellow brown. FW venation typical of genus; 1A forming a right angle, without notch anterior to angle; oblique vein bifurcated, posterior branch almost straight. Cells of D alignment homogeneous. Apex of dorsal field obliquely rounded. Apical field with two cell alignments.
Male genitalia: (Figs 8E View Figure 8 , 15C View Figure 15 , 15D View Figure 15 ) Pseudepiphallus triangular, its basal margin straight, not indented; basal third much wider, lateral margin tapering to a narrower apical third; apical third tapering into a narrow posterior apex, not narrowed pre-apically, apex subacute, without lophi. Rami short, slightly shorter than half of pseudepiphallus length, slightly diverging anteriorly. Pseudepiphallic parameres stout, gently curved but not bent in middle, apex swollen and bilobate. Ectophallic apodemes parallel and long, widened apically, surpassing beyond anterior margin of pseudepiphallic sclerite. Endophallic sclerite with anterior region triangular, barely reaching anterior margin of pseudepiphallic sclerite; its posterior apex trident-like, with short lateral arms not surpassing median posterior expansion.
Female. FW faintly surpassing apex of third tergite, homogeneously brown, without a basal spot (Fig. 9D View Figure 9 ).
Female genitalia: Ovipositor slightly longer than FIII. Copulatory papilla very small, somewhat rectangular, its basal part with sclerotization forming a basal rim, apex almost as wide as base, ended by a narrow stout and truncated lobule (Fig. 10D View Figure 10 ).
