Revision and Phylogenetic Analysis of the Genus Phonoctonus Stal, 1853 (Heteroptera, Reduviidae, Harpactorinae).

ABSTRACT: This paper presents a taxonomic revision and phylogenetic analysis of nine known species of the genus Phonoctonus Stål, 1853, distributed exclusively in the Afrotropical region. The revision and phylogenetic analysis were performed using morphological data. A full redescription for all species is provided, taxonomical problems are clarified, and diagnostic characters are presented and illustrated. Based on the analysis, thirteen species are recognised as valid: Phonoctonus bifasciatus stat. nov., P. caesar, P. elegans, P. fairmairei stat. nov., P. fasciatus, P. grandis, P. immitis stat. rev., P. luridus, P. lutescens, P. nigrofasciatus stat. rev., P. picta stat. nov., P. picturatus stat. rev., and P. principalis. New synonymies are proposed: Phonoctonus nigrofasciatus= P. fasciatus var. poultoni syn. nov., P. picturatus = P. fasciatus var. discalis syn. nov., and P. principalis = P. validus syn. nov. An identification key to separate the species, drawings of dorsal habitus, and distribution maps of all valid species are presented. Performed morphological phylogenetic analyses indicate monophyly of the genus Phonoctonus.

Project description:Simple Summary The members of the Reduviidae family are generally known as “assassin bugs” due to their predatory habits. Peiratinae is one of the largest subfamilies of Reduviidae with a cosmopolitan distribution. Based on the morphological examination on type specimens and other peiratine material from New Guinea, as well as the result of a molecular phylogenetic analysis using COI, 16S and 18S genes, the subgenus Ectomocoris (Sigicoris) Miller, 1958 is elevated to genus level and revised. Four species are recognized and keyed, including three new combinations: S. brumalis comb. nov., S. gracilis comb. nov., S. sexguttatus comb. nov. and one new species, S. dominiqueae sp. nov. The lectotype is designated for Brachysandalus sexguttatus. Pirates concinnus syn. nov. is treated as the junior synonym of S. sexguttatus comb. nov. The systematic relationships, diagnosis, distribution and habitat of this genus are also discussed. Abstract Peiratinae is a cosmopolitan subfamily within Reduviidae with more than 300 known species in 34 genera. There are also some taxa endemic to islands, but their taxonomic status and biology require further study. After examining type specimens of the peiratine species distributed in New Guinea, we found that some of them share many morphological characters, though they were previously assigned in different genera. The phylogenetic analysis based on cytochrome oxidase I, 16S ribosomal RNA and 18S ribosomal RNA genes involving 38 species in 25 genera also supports the result of the morphological study that these species should be involved in a separate genus. In the present study, the subgenus Ectomocoris (Sigicoris) Miller, 1958 is elevated to genus level, Sigicoris stat. nov. Three new combinations, S. brumalis comb. nov., S. gracilis comb. nov., S. sexguttatus comb. nov. and one new species, S. dominiqueae sp. nov. are described or redescribed. The lectotype of Brachysandalus sexguttatus is designated, and Pirates concinnus syn. nov. is treated as the junior synonym of S. sexguttatus comb. nov. A key is provided to separate the four species of this genus. The systematic relationships, diagnosis, distribution and habitat of Sigicoris stat. nov. are briefly discussed.
