The new genus and species of Polyancistrini katydids Tainacanthus ferox gen. nov., sp. nov. is described from specimens collected in the highest mountains of the Dominican Republic, island of Hispaniola. This is the third genus of Polyancistrini known from Hispaniola and the seventh genus of the tribe. Tainacanthus is distinctive due to the unique architecture of its pronotum, which is a large and bulbous shield with an extended metazona that covers and protects the stridulatory apparatus surrounded by a relatively small number of large and sharp spines. Additionally, all legs are armed with larger and more robust spines than those of Polyancistrus Audinet-Serville, 1831, its most likely closest relative. Tainacanthus inhabits the highest mountains of the Dominican Cordillera Central at over 2,400 m above sea level, living among hard-leaf evergreen vegetation interspersed with pine forests. The type locality is included within the Armando Berm\údez National Park, one of the most important protected areas in the Dominican Republic.

In this paper a combination of characters by which Poecilimon species (Orthoptera: Tettigonioidea: Phaneropteridae) can be recognised as members of the P. sanctipauli group are described. Most important are the wide fastigium, short ovipositor and song characters. The morphological characters are figured and described (Table 1), and the song patterns illustrated by oscillograms. The proposed phylogenetic relationships of the members of this group are written as [P. mytilenensis (P. pulcher, P. lodosi, P. sanc- tipauli)]. All species of the group are known from southwest Turkey and some east Aegean islands. The three species P. pulcher, P. lodosi and P. sanctipauli are morphologically and bioacoustically quite similar. P. sanctipauli and P. pulcher are distinct species, P. lodosi, however, possesses a combination of the key characters of the other two species. It may be a relict species or, in our opinion more probably, a species of hybrid origin.

The species of the Poecilimon heroicus-group occur around the Caucasus (from north-eastern Turkey to south-eastern Ukraine). We describe the diagnostic morphological characters of all these species and the male calling song of three of the four spe- cies. Based on this data the following phylogenetic relationship is derived (P. tschorochensis (P. tricuspis (P. heroicus, P. bifenes- tratus))). Within the genus Poecilimon, the species can be recognised by a relatively wide pronotum and large tegmina. In one species, Poecilimon tschorochensis Adelung, 1907 (type species of the monotypic genus Artvinia Karabag, 1962, syn. n.; P. rammei Miram, 1938, syn. n.), the tegmina are very large and the song has unusually low spectral components. This species produced di- syllabic echemes at intervals of about 10 s. In two other species of the group, P. heroicus and P. bifenestratus, the calling song of males consists of an uninterrupted dense sequence of long syllables (syllable duration around 0.5 s; ca. 1 syllable/s at 20\°C). In these species the auditory spiracles are reduced in size in both sexes, and the females have extremely small tegmina and are unable to respond to the male song acoustically, which would be typical for Phaneropteridae. The change in communication from acoustically responding to mute females has not been previously documented within a group of closely related species.
