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 View Figure 25 ). Dorsum of head with broad red brown bands narrowly separated (Fig. 4L View Figure 4 ). Fastigium yellow-brown mottled with brown (Fig. 4L View Figure 4 ). 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 View Figure 5 ). Pronotal disk brown with faint light-colored patterns laterally (Fig. 4L View Figure 4 ). Lateral lobes distinctly darker than pronotal disk, dark brown except red brown near ventral margin (Fig. 6L View Figure 6 ). 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 View Figure 25 ). FW slightly surpassing second tergite, not clearly overlapping. Dorsal field with a very faint cream-colored rounded spot at base (Fig. 9I View Figure 9 ).

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 View Figure 10 ).

Measurements. -

See Table 1 View 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.
