Diagnosis. See the generic diagnosis.

Description. Male. COLORATION. Dorsum dark brown to black with distinct yellowish and orange areas ( Fig. 5A, C ). Head. Black; vertex with two yellow patches each contiguous with inner margin of eye; maxillary plate, clypeus, gula, and buccula weakly tinged with yellow; antennal segment I dark brown; segment II dark brown, fuscous subapically, medial portion with small yellow patch on inner surface, apex with yellow annulation; segments III and IV fuscous; labium fuscous ( Figs 5A, C ). Thorax. Pronotum. Black with two relatively large yellow to contrastingly orange patches contiguous with medial part of posterior margin ( Figs 5A, C ). Scutellum. Black ( Fig. 5A ). Thoracic pleura. Dark brown to black, sometimes weakly tinged with yellow on metepisternum. Hemelytron. Dark brown to black with two contrastingly orange, contiguous, rather small patches, one situated on embolium apically and other localized on cuneus basally; membrane fuscous ( Figs 5A, C ). Legs. Dark brown with yellow and orange areas; femora sometimes weakly tinged with yellow, always with narrow, orange annulation apically; tibiae with rather broad, yellow annulation apically; tarsi dark yellow ( Figs 5A, C ). Abdomen. Dark brown to black ( Fig. 5C ).

Biology. Unknown

Distribution. Central east Madagascar ( Fig. 9 ).

Etymology. It is named after the type locality, Madagascar.

Remarks. In his catalogue, Gorczyca (2006) listed eight Cylapinae species from Madagascar. In addition to the two newly described species, we found a specimen of Fulvius anthocoroides ( Reuter, 1875) in the collection of the Moravian Museum in Brno bearing the following label data: “West MADAGASCAR \ nr. KIRINDI N.P., Andranomena \ Spec. Res.; 27m (Andranovory \ nampela); S20°08'52'' E44°30'52'' \ 1–4.ii. 2013; M. Trýzna lgt.”. Currently, a total of 11 species (including eight endemic) are known from Madagascar.
