Sogalabana ochracea sp. nov.

( Figures 1–7 )

Etymology

The specific epithet comes from the Latin ochraceus, meaning ochre coloured, and refers to the colouration of the species.

Diagnosis

See Diagnosis of the genus.

Description

Total length 0.80–0.92 cm.

Head. Vertex: proportion A/B = 8.66–11.66; posterior and lateral margins straight, lateral almost parallel; disc of vertex almost flat ( Figures 1D ; 2A,B ). Frons: proportion C/E = 0.81–0.90; proportion D/E = 0.98–1.02; lateral margins of frons elevated and weakly arcuate. Clypeus in median portion weakly convex ( Figures 1E,F ; 2C,D ).

Thorax. Pronotum: proportion F/B = 4.66–5.66; anterior margin with median shallow incision ( Figures 1D ; 2A,B ). Mesonotum: proportion G/F = 0.97–1.02, proportion G/B + F = 2.35–2.40, proportion G/H = 0.80–0.96. Tegmina: proportion I/ J = 2.21–2.43; vein Sc ending with one terminal, RA and RP with one or two terminals; vein M ending with eight (female) and ten (male) terminals; vein Cu with five or six terminals ending at postclaval margin ( Figure 3B–F ).

Hind tibia apically with seven teeth ( Figure 2G,H ); basitarsomere with six apical spines in formula 2 + 4 (lateral distinctly larger than internal) ( Figures 2H ; 3A ); lateral spines of second tarsomere well developed, median lobe not exceeding level of spines ( Figure 2H ).

Male genitalia. Anal tube (in lateral view; Figures 3G ; 5A ) twice as long as wide; basal part rectangular, apical part tapered, apex rounded. Anal tube (in dorsal view; Figures 3H ; 5B ) with anterior and posterior margins almost straight. Pygofer (in lateral view; Figure 3G ) with dorsal margin concave. Genital styles (in lateral view; Figures 3G ; 5C ) with ventral margin arcuate and dorsal margin almost straight.

Phallic complex. Dorsal part of periandrium: ventral process narrow, arcuate, with four small dorsal teeth; dorsal process longer and more massive than ventral process, with denticulate upper margin and horn-like apex. Ventral part of periandrium: ventral surface with row of seven to nine denticles ( Figure 5D,E ). Aedeagus: dorsal part apically with deep rectangular incision ( Figure 5G ).

Female genitalia. Anal tube (in dorsal view; Figures 4C ; 6B ): anterior margin almost straight.

Gonoplac: posterior margin with row of five or six teeth ( Figure 6C,D ). Spermatheca: ductus receptaculi ribbed, long and widened subapically; diverticulum ductus smooth, basal part tubular, apical part elongated and widened apically in form of membranous bulla ( Figure 7A,B ).

Colouration. General colour ochre (yellow-reddish-brown), two black dots on lateral parts of pronotum.

Type material

Holotype, ♂: [ Madagascar Nord , Rég. Tsaratanana, N.M. Mangidrano], [Analabana, IV-1964, 1640 m. P. Soga], [Museum Paris] – MNHN

Paratype, 1♀: the same locality labels as in Holotype – MNHN

Note: According to the literature, locality data of type-specimens seems to be incomplete and written incorrectly. The only work with the same locality data is that of Montreuil (2010); however, in many other papers the locality is cited as follow: Madagascar Nord, Région du Tsaratanana, N.O. de Mangindrano, Analabana, 10/ 20-IV-1964, 1640 m, P. Soga.

Distribution

Madagascar: Mahajanga Province, Sofia Region, Bealanana district, Mangidrano commune.
