PROC. ENTOMOL. SOC. WASH. 95(2), 1993, pp. 152-162 THE ANTHONOMUS CAVEI SPECIES GROUP (COLEOPTERA: CURCULIONIDAE) Wayne E. Clark and Horace R. Burke (WEC) Alabama Agricultural Experiment Station, Department of Entomology, Auburn University, Alabama 36849-5413, U.S.A.; (HRB) Department of Entomology, Texas A&M University, College Station, Texas 77843, U.S.A. Abstract. —Three new species of neotropical Anthonomini, A. cavei (El Salvador, Hon-duras, Mexico, Panama), A. ironia (Colombia) and A. praetextum (Brazil), are assigned to the Anthonomus cavei group. Adults, larvae and pupae o{ A. cavei were collected on Byrsonima crassifolia (L.) H.B.K. (Malpighiaceae), and adults of A. praetextum were collected on an unidentified Malpighiaceae. Characters diagnostic of the A. cavei group and of each of the species are described and some are illustrated. A key to the species is presented. The A. cavei group appears to be most closely related to the A. furcatus group. Key Words: Neotropical Anthonomini, Malpighiaceae, Byrsonima, immature insects The assertion ". . . not found in BCA . . ." is part of a label on a Panamanian weevil in the collections of the U.S. National Mu-seum of Natural History (USNM). Made with a lead pencil on folded yellow paper, the inscription is in the hand of the U.S. Department of Agriculture scientist in charge of the weevil collections at the USNM between 1929 and 1949, L. L. Buchanan. The statement alludes to the fact that the specimen represents a species that is not among the Central American Anthonomini treated in the Biologia Centrali-Americana (Champion 1903, 1906, 1910). The aforementioned label also states ". . . Anthonomus of flavirostris group . . . ," but the species does not belong with the species presently assigned to the A. flavirostris group (Clark 1990). Nor does the species fit con-veniently in any of the other previously rec-ognized Anthonomus species group. Thus it is placed along with two additional, related, likewise previously undescribed species, in the A. cavei group. Descriptions, illustrations, and a key to adults of these three species in the A. cavei group are presented in this paper. Descrip-tions of the larval and pupal stages of one of the species are also provided.
