Tylopsis bilineolata Karsch, 1893

( Fig. 5 )

MADAGASCAR: Ranomafana , rain forest, Soarana trail, 920 m a. s. l., - 21.256813° S, 47.422720° E ; 25 iii 2015, leg. Anton Krištín, CH 8596, male.

From Madagascar, two species of the genus Tylopsis are known: T. bilineolata Karsch, 1893 (see Ragge 1964) and T. irregularis Karsch, 1893 (see Massa 2017c). From the shape of the cerci ( Fig. 5A ) and the pronotum ( Fig. 5B ), our specimen belongs to T. bilineolata , and here to the larger and more common morph (length of hind femur 25 mm; see Ragge 1964). Its stridulatory file ( Fig. 5C ) is quite similar to that of T. lilifolia (Fabricius) (compare Heller 1988, fig. 110).

Habitat. The specimen was found in a bush within tall tropical rainforest with many palm species and several tree fern species.
