Representatives of the Orthopteran suborder Ensifera (crickets, katydids, and related insects) are well known for acoustic signals produced in the contexts of courtship and mate recognition. We present a phylogenetic estimate of Ensifera for a sample of 51 taxonomically diverse exemplars, using sequences from 18S, 28S, and 16S rRNA. The results support a monophyletic Ensifera, monophyly of most...

Cardiodactylus is a speciose cricket genus belonging to the subfamily Eneopterinae. One new species of Cardiodactylus from Singapore is described: Cardiodactylus admirabilis Tan & Robillard n. sp. Acoustic analysis is also performed on the male calling song. A key to species of Eneopterinae from Singapore is provided.

Caconemobius are distributed on widely separated islands in the Pacific area. Wings are absent in these species. They live among the rocks along the seashore, including the Hawaii, Japan and Korea. This genus is presently represented by 14 species worldwide. We found the first species of Caconemobius from China on the coast of Guangzhou. One new species, Caconemobius dibrachiatus Ma and Zhang, ...

Pteroplistes Brunner von Wattenwyl, 1873 is an Indo-Malaysian cricket genus with only one species, P. platycleis Bolivar, 1899(1900) known from India. Here, we redescribe the genus Pteroplistes and P. platycleis and describe two new Indian species, Pteroplistes kervasae Jaiswara, n. sp. and Pteroplistes masinagudi Jaiswara, n. sp. from the Western Ghats, using morphology and genitalia. Identifi...

In the present study, we address Lebinthus cricket species from Luzon (Philippines) being sympatric in Mount Makiling. We describe Lebinthus puyos new species and redescribe the species Lebinthus sanchezi Bolivar, 1889 and select a neotype series. The species Lebinthus makilingus Otte, 2007 is synonymized under Lebinthus sanchezi. For each species we provide complete descriptions of morphology,...

Stalacris n. gen. (Insecta, Grylloidea, Phalangopsidae) is described from South Africa using characters of morphology and male genitalia. This taxon, known from only two species, Stalacris meridionalis n. gen., n. sp. and Stalacris sp, is characterized by the unique structure of its forewings. These are prolonged distally as long, acute and more or less articulated processes, forming a kind of ...

This study describes a new genus and species of Neoaclini cricket based on specimens collected in the Brazilian Atlantic forest. In addition to the morphological description, we also report karyotype. Ubiquepuella telytokous n. sp. represents the first recorded occurrence of parthenogenesis in Grylloidea. Although the exclusively parthenogenetic reproduction is rare in Orthoptera, we acknowledg...
