Diagnosis. Perinetella nigroflava is similar to P.fiedleri sp. nov. but differs in the following characters: process of periandrium with two arms oriented ventro-basad, anterior arm single and distinctly shorter than posterior one; posterior arm bifurcate, lower process shorter than upper one ( Fig. 37).
Redescription. Measurements. Total length: 12.60–14.50 mm. Vertex:A/B 5.43–8.00. Frons: C/ E 0.56 –0.65; D/ E 0.67 –0.88. Pronotum: F/B 3.14–4.40. Mesonotum: G/F 4.26–5.14; G/ B+F 3.38–4.07; G/H 0.88–1.05. Tegmina: sutural angle rounded, I/J 1.74–1.90.
Coloration. Head dark brown; frons black, lateral parts yellowish. Pronotum brownish-yellow, mesonotum and legs black. Abdomen with sternites black, tergites yellow. Tegmina yellowish with black dot at base ( Figs 1–4 View Figs 1–4 ).
Male terminalia. Anal tube, in lateral view, with apical part widely rounded ( Figs 31, 32 View Figs 29–34 , 35); in dorsal view, with apical part elongately oval ( Figs 29, 30 View Figs 29–34 , 36). Genital style with weakly arcuate or almost straight dorsal margin, lower part of posterior margin concave, upper part convex; ventral margin almost straight; capitulum short and wide ( Figs 32, 33 View Figs 29–34 , 35). Periandrium ( Figs 37, 38) with ventral margin of dorsal part bearing well-developed lobe; apical process of dorsal periandrium with two arms oriented ventro-basad, anterior arm single and distinctly shorter than posterior; posterior arm bifurcate, lower process shorter than upper; posterior arms in some specimens showing asymmetry (not bifurcated).
Female terminalia. Pregenital sternite with anterior margin slightly produced medially and posterior margin weakly arcuate; median part and margins well sclerotized ( Fig. 47 View Figs 47–54 ). Anal tube, in lateral view, with ventral margin distinctly rounded ( Figs 43, 44 View Figs 41–46 ). Gonoplac with weakly sclerotised, elongate area alongside ventral margin ( Figs 48, 49 View Figs 47–54 ).
Etymology. The specific epithet comes from a combination of Latin adjectives: nigrus – black and flavus – yellow, and reflects the coloration of the species.
Distribution. Madagascar: former Toamasina and Fianarantsoa provinces ( Fig. 67 View Fig ).
Remark. SYNAVE (1956) in his original description mentioned four paratypes; however, in his later paper concerning the types in IRSNB, he listed only two ( SYNAVE 1980). This information was confirmed by MEDLER (1993a). We also could examine only these two paratypes in our study.
