Diagnosis. Peridinetus concentricus is widespread in the Greater Antilles and has been confused frequently with P. roeselii , a slender species with a sexually dimorphic rostrum and subconnate claws. Peridinetus poeyi , a poorly known Cuban species, has a slightly different colour pattern ( Fig. 8 ).

Distribution. The species occurs on the Greater Antillean islands except Jamaica.

Plant associations. Piperaceae : Piper aduncum , P. amalago , P. medium , P. nigrum , P. peltatum ( Wolcott 1924, 1936, 1951; Marcano & Abud 1995; Alvarez Puente & Grillo Ravelo 2003). Records from Blechum pyramidatum (Acanthaceae) , Chamissoa altissima (Amaranthaceae) , Clidemia hirta (Melostomataceae) , Guarea guara (Meliaceae) , Hedychium coronarium (Zingiberaceae) , Heterotrichum octonum (Melostomataceae) , Odontonema cuspidatum (Acanthaceae) , Pavonia fruticosa (Malvaceae) , Spathodea campanulata (Bignoniaceae) , Syngonium podophyllum (Araceae) , Syzygium jambos (Myrtaceae) , Thelypteris tetragona (Thelypteridaceae) , Triunfetta rhomboidea (Tiliaceae) [all Alvarez Puente & Grillo Ravelo 2003] are probably accidental associations, as Piper and Peperomia species are confirmed hosts for 19 Peridinetus species (Prena, in prep.).

Discussion. Chevrolat (1876) transferred Rhynchaenus concentricus Olivier to Peridinetus and remarked that Schönherr and Lacordaire apparently overlooked this species. However, Schönherr (1837: 457; 1845: 56) had listed it under Conotrachelus (thereby following Dejean 1835, 1836) and the resulting dual identity has been maintained in catalogues ever since. The synonymy of P. concentricus and P. signatus was first recognised by Gundlach (1893: 323), though with reversed precedence. Wolcott (1924: 131) followed priority but lumped P. concentricus with P. poeyi . Later, Wolcott (1951: 409) changed priority again and confused P. concentricus with P. m a c u l a t u s, a synonym of P. roeselii .
