Robert S. ANDERSON Entomology-Canadian Museum of Nature, Ottawa NEW SPECIES OF SICODERUS VANIN FROM THE VIRGIN ISLANDS (COLEOPTERA: CURCULIONIDAE; CURCULIONINAE; OTIDOCEPHALINI) Anderson, R. S. 1999. New species of Sicoderus Vanin from the Virgin Islands (Coleoptera: Curculionidae; Curculioninae; Otidocephalini). — Tijdschrift voor Entomologie 141 [1998]: 129-135, figs. 1-1 2. [issN 0040-7496]. Published 1 March 1999. Three new species of the genus Sicoderus Vanin from the Virgins Islands of the Greater Antilles are described. The three new species are Sicoderus ivieorum sp. n., S. hirsutiventris sp. n., and 5. vanini sp. n. They are placed in the S. tinamus species group and compared with known West Indian Sicoderus. A key to all Sicoderus in the West Indies (including Florida) is presented. Robert S. Anderson, Entomology-Canadian Museum of Nature, P.O. Box 3443, Station D, Ottawa, ON. KIP 6P4, Canada. E-mail:
[email protected] Key words. -Weevil; biogeography; inventory; West Indies The genus Sicoderus is well-represented in the is-lands of the West Indies with ten recognized species in two species groups found there (Vanin 1986). The four members assigned to the S. delauneyi group are found on the islands of the Lesser Antilles as far north as Guadeloupe, whereas the six species of the S. tina-mus group are known from southern Florida and the Bahamas, Cuba and Hispaniola. Recent collections of Sicoderus from the British and U.S. Virgin Islands (and Puerto Rico) bridge the geographical gap be-tween the ranges of species in these two groups and represent three undescribed species in the S. tinamus species group. Descriptions of these new species follow the format used in Vanin (1986) to facilitate comparisons with species treated therein. A revised key to all Sicoderus species occuring in southern Florida, the Bahamas and the West Indies is presented. Specimens are deposited in the Canadian Museum of Nature, Ottawa, Ontario, Canada (cmnc), the col-lection of Charles W. O'Brien, Tallahassee, FL. (cwob), the collection of Michael A. Ivie, Bozeman, MT. (maic), and the United States National Muse-um, Washington D.C. (usnm). Sicoderus ivieorum sp. n. (figs. 1-5) Description Length male, 5.2-6.2 mm; female, 4.8-7.2 mm. In-tegument black, shining. Rostrum 0. 97-1. 00 X length elytra in male; 1.09-1.17X length elytra in female. Antennal insertion submedial in male and female. An-tenna with article II of funicle 1.49-1.57X length ar-ticle III in male; 1. 27-1. 29 X length article III in fe-male. Prothorax with length 1.17-1. 19 X width in male; 1. 23-1. 26 X width in female. Prothorax con-stricted anteriorly, globose, widest at anterior one-third; punctures well-separated, sparse, very fine and shallow on disk, slightly deeper and larger in anterior one-quarter and very slightly deeper on flanks; with scattered, erect setae along anterior constriction. Ely-tra with length 1. 86-1. 88 X width in male; 1.88-1.93X width in female; in dorsal view distinctly widest at midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; with isolated, erect but short (perhaps abraded or broken), setae in suturai region; apices con-jointly rounded. Strial punctures evident, shallow, moderately fine. Membranous wings lacking. Meta-sternum with punctures well-separated, moderately fine and shallow; first row of punctures alongside met-episternum consisting of 3 or 4 widely spaced, shallow punctures. Abdominal ventrite I of male moderately raised in middle near apical margin forming a moder-ately elevated tubercle with two small subcontiguous patches of setosity at tip; of female, moderately swol-len in middle near apical margin but not tuberculate, not setose. Ventrite V of male with rounded shallow impression in apical three-quarters; of female, uni-formly convex. Legs with all femora with distinct ven-tral tooth; tooth slightly larger on anterior legs; tarsal claws with small basal tooth. Aedeagus with shallow apical notch; slightly expanded laterally near apex; in-129
