NEOTROPICAL NABIDAE (HETEROPTERA), 3: SPECIES OF THE GENUS ARACHNOCORIS FROM COSTA RICA

A. panamensis (Dist.), A. eberhardi, n. sp. and A. setosus, n. sp. are found in Costa Rica in the webs of pholcid spiders. Species of the neotropical genus Arachnocoris live in spider webs. Nine species were known prior to this study. In 1985 Dr. R. T. Schuh (American Museum of Natural History, New York) kindly sent me a tube with alcohol preserved specimens of the genus Arachnocoris labelled "Costa Rica, Heredia, La Selva-Ca. Pto Viejo, 100 m, in webs of pholcids, 111. 1983, W. Eberhard." The material contains 3 species, two of which are new and the third represents a new record for Costa Rica. Holotypes and paratypes of new species are in the American Museum of Natural History, one paratype of each species is retained in the Zoological Institute, Academy of Sciences of the USSR.
