Diagnosis. Perinetella flavomarginata sp. nov. differs from P. nigroflava and P. fiedleri sp. nov. in the following characters: coloration, tegmen with its sutural angle acute and slightly produced, male terminalia with apical part of anal tube rounded and lower part of posterior margin of stylus widely rounded.

Description. Measurements. Total length: 15.3–16.3 mm. Vertex: A/B 7.00–7.83. Frons: C/ E 0.66 –0.69; D/ E 0.86 –0.88. Pronotum: F/B 3.67–4.17. Mesonotum: G/F 5.08–5.95; G/ B+F 4.10–4.68; G/H 1.06–1.14. Tegmina: sutural angle acute and slightly produced, I/J 1.73–1.80.

Coloration. General coloration milky white. Tegmen with costal, apical and postclaval margins yellow; black dot at the base ( Figs 64–66 View Figs 64–66 ).

Male terminalia. Anal tube, in lateral view, with apical part tapering apicad ( Fig. 58 View Figs 55–63 ); in dorsal view, with apical part rounded ( Fig. 59 View Figs 55–63 ). Genital style with strongly convex dorsal margin, lower part of posterior margin widely rounded, ventral margin weakly arcuate; capitulum long and sharp ( Fig. 58 View Figs 55–63 ). Periandrium with ventral margin of dorsal part with weakly developed lobe; apical process of dorsal periandrium with two arms; anterior arm single and distinctly shorter than posterior one, oriented dorsad; posterior arm bifurcate, oriented ventro-basad, lower process shorter than upper one ( Figs 60–61 View Figs 55–63 ). The specimen from MNHN has partly damaged genital capsule with right apical process of dorsal periandrium missing; left apical process with posterior arm not bifurcated and slightly more widened than in specimens from Andobo.

Female. Unknown.

Etymology. The specific epithet comes from a combination of the Latin adjectives: flavus – yellow and marginatus – bordered, referring to the coloration of the tegmen.

Distribution. Madagascar: former Toamasina and Mahajanga provinces ( Fig. 67 View Fig ).

Remark. After the examination of the holotype (female) of Phyma basipunctata Schmidt, 1906 from the collection of the Musée royal de l’Afrique Centrale in Tervuren, we can confirm the statement of MEDLER (1993b) that Ph. basipunctata is a junior synonym of Flatopsis nivea ( Signoret, 1860) . However, the specimens from Andobo (collection of IRSNB) determined by Medler as Flatopsis nivea were wrongly assigned to this species and in fact represent Perinetella flavomarginata sp. nov.
