Type locality. -

INDONESIA: West Papua: Faowi.

Etymology. -

This species is named after the type locality Faowi; noun in apposition. Even though three species of Rugabinthus are found in Faowi, this species was the most abundantly collected.

Diagnosis. -

This new species is close to R. manokwari sp. nov., R. kencana sp. nov., and R. maoke sp. nov. in terms of male FW venation with 1A not indented, and by male genitalia with pseudepiphallus triangular. This new species differs from R. manokwari sp. nov. by larger size, darker coloration, apex of pseudepiphallus not indented, and slight difference in shape of pseudepiphallic parameres. This new species differs from R. kencana sp. nov. and R. maoke sp. nov. by lateral margins of pseudepiphallus more indented in the middle and shape of pseudepiphallic parameres.

Description. -

Large sized among congeners (Fig. 14 View Figure 14 ). Dorsum of head with broad red brown bands narrowly separated (Fig. 4D View Figure 4 ). Fastigium red brown (Fig. 4D View Figure 4 ). Scapes red brown. Fastigium verticis and frons brown, frons with very faint light spots; clypeus and mouthparts brown, labrum distinctly cream-colored (Fig. 5D View Figure 5 ). Pronotal disk red brown with some irregular yellow brown patterns laterally and near the anterior margin, with lighter lateral ovular spots near anterior half and with a yellow brown stripe near the latero-posterior margin (Fig. 4D View Figure 4 ). Lateral lobes not darker than disk (Fig. 6D View Figure 6 ). FIs and FIIs yellow brown with dense dark spots and patterns (less dense in inner surface of FIIs); TIs dark brown with a broad cream-colored ring in middle, TIIs with one or two incomplete rings. FIIIs brown, knees dark brown to black. Tergites brown, with posterior margin darker.

Male. FWs reaching middle of fourth abdominal tergite. FW coloration (Fig. 7D View Figure 7 ): Dorsal field cells and veins mostly brown; with area between M and R infumate cream-colored; basal area with a cream-colored spot on external corner. Lateral field with brown veins, cells with dorsal part brown, otherwise cream-colored. FW venation typical of genus; 1A forming a right angle, slightly bisinuate anterior to angle; oblique vein posterior branch almost straight, anterior one bifurcated. Apical field with two cell alignment posterior to D alignment. Apex of dorsal field rounded.

Male genitalia: (Figs 8D View Figure 8 , 15A View Figure 15 , 15B View Figure 15 ) Pseudepiphallus triangular, slightly convex dorsally in lateral view; its basal margin straight, not indented, slightly widened laterally at base of rami; basal third much wider and lateral margins tapering to a narrower apical third; posterior third forming a thick spoon-like finger, gently tapering into a narrow posterior apex, truncated and without lophi. Rami short, shorter than half of pseudepiphallus length, slightly diverging anteriorly. Pseudepiphallic parameres stout, somewhat straight, and not bent or curved, with small internal lobule in middle, apex not swollen and obtuse. Ectophallic fold triangular, membranous apically, with parallel lateral sclerites. Ectophallic apodemes parallel and long, surpassing beyond anterior margin of pseudepiphallic sclerite with lateral arms elongated triangular. Endophallic sclerite with anterior region triangular, barely reaching anterior margin of pseudepiphallic sclerite; its posterior apex trident-like, with tongue-shaped lateral arms not surpassing large median posterior expansion.

Female. FW slightly surpassing second tergite, with a small cream-colored rounded spot at base and one fainter at apex (Fig. 9C View Figure 9 ).

Female genitalia: Ovipositor distinctly longer than FIII. Copulatory papilla globular, its base with a semi-complete ring-like sclerotization; apex folded ventrally, short and rounded, slightly sclerotized on apical face (Fig. 10C View Figure 10 ).
