ABSTRACT. Two new taxa, Andasibeacla Gorochov, gen.n. and A. tianasoai Gorochov, sp.n., probably belonging to the tribe Phalangopsini, are described from the Toamasina Province of Madagascar. A new species is type and alone species in this genus; it is found on bark of tree trunks in tropical forests. The new genus is characterized by the following features: the body is rather small, spotted and almost apterous; the head has a narrow and well separated rostral part; the thoracic segments lacks any notal gland, but the male abdominal dorsum is with a characteristic transverse keel (this keel is low and rounded in profile, possibly it is an abdominal gland); the legs are long, rather thin, without tympana and denticles on hind tibiae; the structures of the abdominal apex in the both sexes are rather simple and do not allow us to establish а subtribal position of this genus.
KEY WORDS: Taxonomy, Orthoptera, Gryllidae, Phalangopsinae, Madagascar.
