Type locality. -

INDONESIA: West Papua: Star Range

Etymology. -

This species is named after the Maoke Mountain Range where Star Range was situated within; noun in apposition.

Diagnosis. -

This new species is very similar to R. kencana but differs by overall larger size, distinctly larger pseudepiphallus, and endophallic sclerite with lateral arms more elongated and pointing more externally.

Description. -

Large sized among congeners (Fig. 18 View Figure 18 ). Dorsum of head with broad red brown bands faintly to narrowly separated (Fig. 4G View Figure 4 ). Fastigium red brown (Fig. 4G View Figure 4 ). Scapes dark red brown. Fastigium verticis and frons dark red brown, black beneath scapes; clypeus and mouthparts pale brown with darker patterns (Fig. 5G View Figure 5 ). Pronotal disk red brown with some faint and irregular paler brown patterns (Fig. 4G View Figure 4 ). Lateral lobes faintly darker than disk, dark brown except for a yellow spot on ventral margin (Fig. 6G View Figure 6 ). FIs and FIIs yellow brown with a few dark spots near knees, TIs dark with a pale yellow ring in middle, TIIs mostly dark. FIIIs brown, knees dark brown. Tergites brown, with posterior margin darker.

Male. FWs reaching base of fourth abdominal tergite. FW coloration (Fig. 7G 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 part sinuated. Cells of D alignment widened posteriorly. Apex of dorsal field obliquely rounded.

Male genitalia: (Figs 8G View Figure 8 , 15G View Figure 15 , 15H View Figure 15 ) Pseudepiphallus very similar to R. kencana , triangular with an indented, narrow apical third with subacute apex, but differs by being distinctly larger. Rami, pseudepiphallic parameres and ectophallic apodemes similar. Endophallic sclerite with anterior region triangular, not reaching anterior margin of pseudepiphallic sclerite, with long posterior lateral arms pointing diagonally and surpassing median expansion.

Female. Unknown.
