Diagnosis. Of the three species with subconnate claws, only P. roeselii occurs in Cuba. The elytral vestiture consists of three fasciae, at the base, middle and apex, with the median fascia composite and occasionally surrounding an obsolete, dark macula ( Fig. 9 ). The other two species, P. decipiens and P. fuscosignum , are restricted to Hispaniola and have a different colour pattern.

Material examined. Holotype of H. roeselii , labeled “ Typus ”, “ Roeseli / Sch Cuba ”, white disk “69”, “351/ 82”, “Riksmuseum/ Stockholm”; 2 other specimens mentioned by Chevrolat (1883: 82] probably no types ( NHRS, Chevrolat Collection). 3 syntypes of P. maculatus , labeled as holotype, allotype and paratype ( NHRS, Schönherr Collection). CUBA. Cienfuegos: Soledad ( CWOB 2). Granma: upper Yara valley ( USNM 1). La Habana: Baracoa ( USNM 3). Pinar del Río: San Blas ( USNM 1). Sancti Spiritus: Mina Carlota, Trinidad Mts. ( CWOB 1, USNM 3); Topes de Collantes ( JPPC 1); Pico Potrerillo ( CWOB 10). Site unspecified ( CWOB 1, DEI 1, NHRS 4, USNM 3, MNHUB 8). Total 39 specimens.

Distribution. Peridinetus roeselii is endemic to Cuba. The type locality, given as “ Brasilia ” and questioned by Schönherr (1843: 89), is erroneous. The records from Puerto Rico ( Wolcott 1924, 1936, 1951; O’Brien & Wibmer 1982) refer to P. concentricus .

Plant associations. Piper peltatum [as Caisimón] ( Gundlach 1891).

Discussion. This species was described erroneously in duplicate by Schönherr’s co-workers, as Heilipus roeselii by Boheman (1836) and as Peridinetus maculatus by Rosenschöld (1837). Schönherr (1845) synonymised these names under P. maculatus and credited the authorship to Sturm (1843), who had proposed this epithet in litteris as early as 1826 ( Sturm 1826). The superficial similarity with other West Indian Peridinetus species caused further confusion regarding its name and distribution. Gundlach (1893) mentioned P. maculatus (with Heilipus roeselii as a synonym) in his faunal list of Puerto Rico, but noted that the species occurs only in Cuba. Wolcott (1924, 1936) considered P. poeyi as a synonym of P. concentricus and mentioned Puerto Rican specimens deposited in the AMNH, but later he suggested that P. concentricus and P. maculatus are synonyms of P. signatus , no longer referring to P. poeyi ( Wolcott 1951) . Wolcott was correct in that all his Puerto Rican specimens are one and the same species, i.e., P. concentricus , but erroneously included therein two other species from Cuba. O’Brien & Wibmer (1982) were the first to give P. roeselii precedence over P. maculatus but repeated Wolcott’s erroneous record from Puerto Rico.
