“…The genus, as currently recognised, comprises the following valid species: jugularis (Peters, 1865) (the type species), acetabulosus (Hermann, 1804), norfolkensis (Gray, 1839), planiceps (Peters, 1866), beccarii Peters, 1881, kalinowskii (Thomas, 1893), loriae (Thomas, 1897), minutus (Miller, 1899), doriae Andersen, 1907, phrudus (Handley, 1956, eleryi Reardon & McKenzie, 2008, and francoismoutoui Goodman et al, 2008(Simmons 2005Goodman et al 2008). Some authors have recognised 'species groups' within this suite of species that largely correspond to geographic regions, namely, the acetabulosus group (jugularis (Madagascar), acetabulosus and francoismoutoui (Mascarene Islands), and doriae (Sumatra)), the kalinowskii group (kalinowskii and phrudus (western South America), and minutus (Cuba)) and the norfolkensis group (beccarii, loriae, norfolkensis, planiceps (Indo-Australia)) (Koopman 1994;Simmons 2005).…”
