Material examined. -

Holotype: INDONESIA • ♀; West Papua: Yapen Island, Aiam Range, Mount Baduri, Japen Seroei Camp 1, 1000 ft. a.s.l.; September 1938; B.M. 1938-593; molecular sample L172; L. E. Cheesman leg; NHMUK.

Type locality. -

INDONESIA: West Papua: Yapen Island, Mount Baduri.

Etymology. -

This species is named after the type locality, Mount Baduri; noun in apposition.

Diagnosis. -

This new species differs from all congeners by its stocky shape, frons mostly cream-colored with some dark patterns, scapes whitish, and by last abdominal tergite forming a median sinuate expansion above suranal plate.

Description. -

Average sized among congeners, but stocky (Fig. 25). Dorsum of head with broad red brown bands narrowly separated (Fig. 4L). Fastigium yellow-brown mottled with brown (Fig. 4L). Scapes whitish with some faint brown patterns. Fastigium verticis cream-colored with two lateral rectangular dark spots beside scapes; two median oval brown spots expanded ventrad to frons as band. Frons yellow brown with brown bands widening and diverging from each other; slightly brownish beneath scapes. Clypeus yellow-brown and brown in middle, mouthparts brown to dark; maxillary palpi mostly yellow (Fig. 5L). Pronotal disk brown with faint light-colored patterns laterally (Fig. 4L). Lateral lobes distinctly darker than pronotal disk, dark brown except red brown near ventral margin (Fig. 6L). FIs and FIIs yellow brown with large dark spots and patterns, knees dark-brown; TIs and TIIs brown with very faint pale bands. FIIIs brown, knees dark brown to black.

Male. Unknown.

Female. Last abdominal tergite forming a median sinuate expansion partly covering suranal plate (Fig. 25C). FW slightly surpassing second tergite, not clearly overlapping. Dorsal field with a very faint cream-colored rounded spot at base (Fig. 9I).

Female genitalia. Ovipositor about as long as FIIIs. Copulatory papilla globular, its base with two hemi-circular ring-like sclerites; apex short, rounded with tip slightly pointed, folded ventrally, and slightly sclerotized dorsally (Fig. 10J).

Measurements. -

See Table 1.

Remark. -

This new species is known only by the female type specimen, which makes it difficult to place it in a particular genus among the Lebinthina . Its stocky shape first suggested it could belong to Gnominthus, but a molecular phylogenetic study in preparation revealed that this species belongs to the clade corresponding to Rugabinthus without ambiguity.
