Paduniella ambra , new species

Figs 7–9

Paduniella ambra resembles P. nandra in the possession of a posterior projection of tergite IX. This species differs from P. nandra by having inferior appendages and sternal strips narrower, and superior appendages and apex of phallicata broader in lateral view.

Male genitalia ( Figs 7–9 ). Sternite IX narrowly club-shaped in lateral view; both ventral arms with almost straight posterior and anterior margins, 3 times longer than wide, about 0.1 mm long; without swelling at posterior apex; both dorsal arms narrowing dorsad, nearly needle-shaped, straight, oriented anterodorsad, joined with tergite IX at mid-height of genitalia, about 0.2 mm long. Ventral and dorsal arms forming right angle. Tergite IX long, smooth, in lateral view with nearly parallel-sided, straight dorsal and ventral margins; posterodorsad produced apex exceeding basis of superior appendages; dorsal margin nearly straight. Superior appendages originating from posteroventral corner of tergite IX; thick, straight, with nearly straight ventral margin and convex dorsal margin, slightly wider than widest part of sternite IX; setae present along entire length; apex rounded. Median branch of inferior appendages invisible in lateral view; originating proximally on main branch in ventral view; parallel-sided, apex bifurcate; mesal apical lobe longer than lateral apical lobe; covered by setae, especially along mesal margin; nearly 0.13 mm long. Ventral lobe of inferior appendages absent. Main branch of inferior appendages weakly narrowing distad along entire length; proximal part about as wide as widest part of superior appendages in lateral view; bending ventrad at midlength; about 0.45 mm long. Phallic apparatus connected to sternite IX and tergite IX by long, narrow, dorsally narrowing sternal strips; anterior four-fifths of strips weakly bow-shaped; strongly bent dorsad before pointed apex. Phallobase about 0.2 mm long; located above basis of phallicata, nearly straight, with convex ventral margin and irregular dorsal margin; wider than sternal strips. Median processes nearly 0.5 mm long, needle-shaped, weakly curved ventrad from mid-length; originating from anterior part of phallobase; each apex slightly exceeding phallicata. Phallicata strongly club-shaped; basal half slender, straight, parallel-sided; apex broad, nearly symmetrical, weakly concave ventral margin, dorsal margin slightly convex. Paramere separated from phallicata at mid-length of phallobase; needle-shaped along its length, running parallel with phallicata, exceeding phallicata and median process; nearly 0.4 mm long.

Holotype male, Mt. d’Ambre, Les Roussettes (no date) [Stuckenber] ( MNHN, alcohol).

Paratypes: Same data as holotype, 2 males. Mt. d’Ambre, xii.1949 [Paulian], 1 male ( NHRS, alcohol), 2 females ( MNHN, alcohol).

Distribution. Madagascar (Province Antsiranana).

Etymology. The name, ambra , is derived from Mt. d’Ambre, the type locality of this species.
