Rugabinthus newguineae (Bhowmik, 1981) comb. nov.

(Figs 3 , 4N , 5N , 6N , 9K , 10M , 27)

Larandopsis newguineae Bhowmik, 1981[1979]: 39 - Desutter-Grandcolas and Jaiswara 2012: 31, according to Bhowmik’s descriptions and illustrations belonging to Lebinthus [but not moved to Lebinthus ] - Cigliano et al. 2021 ( Orthoptera Species Files Online).

Macrobinthus newguineae - Robillard et al. 2016: 178.

Material examined. -

Holotype: INDONESIA • ♀; Dutch New Guinea : Cyclops Mts, Sabron Camp 2; 2000 ft; July 1936; identified Larandopsis newguineae Bhowmik by H. K. Bhowmik, 1973; L. E. Cheesman leg; BMNH-1936-271.

Other material. -

INDONESIA • 1♀; N. New Guinea, “Boven-Jemomaissin” ca. 400 m; 4 April 1911; molecular sample L199; Dr P. N. v. Kampen, Ned. Nw. Guinea Exp leg; RMNH • 1♀; N. New Guinea; 1911; Dr P. N. v. Kampen, Ned. Nw. Guinea Exp leg; RMNH • 1♀; N. New Guinea; April-May 1911; Dr P. N. v. Kampen, Ned. Nw. Guinea Exp leg; RMNH.

Type locality. -

INDONESIA: Cyclops Mts.

Emended diagnosis. -

Among congeners, R. newguineae comb. nov. is characterized by its large size, FWs not reaching abdomen mid-length but well developed, coloration homogeneously dark brown, and very long ovipositor.

Description. -

See Robillard et al. (2016).

Remark. -

This species is known only by female specimens until now, which makes it difficult to place it in a genus among the Lebinthina because several genera share the same general shape, such as Rugabinthus and Macrobinthus , while being mostly characterized by male characters (FW venation and genitalia). A molecular phylogenetic study in preparation revealed that this species belongs to the clade corresponding to Rugabinthus , justifying the new combination proposed here.
