discussion
Remarks. The resurrection of the genus Omalacantha from the synonymy of Microphrys was underpinned by molecular data combined with less obvious morphological support (Windsor & Felder 2014). Clearly, the morphological differences between the two genera need to be more intensively investigated. Omalacantha as understood by Windsor & Felder (2014) consists of four species, namely: O. antillensis (Rathbun, 1920) [Microphrys], type locality: off Montego Bay Point, Jamaica; O. bicornuta (Latreille, 1825) [Pisa], type locality: “ Nouvelle Hollande ” – could be either Dutch Guiana, Saba, Saint Eustace, St. Martin’s or Tobago, at that time under Dutch control (Boone 1930 a: 111); O. garthi (Lemos de Castro, 1953) [Eucinetops], type locality: Barra de Guaratiba, state of Rio de Janeiro; and O. interrupta (Rathbum, 1920) [Microphrys]. The species in Omalacantha are in need of a thorough taxonomic review, including better descriptions and illustrations.
