1. Generic Revision of the Smaller Nasute Termites of the Greater Antilles (Isoptera, Termitidae, Nasutitermitinae)

   Yves Roisin, Rudolf H. Scheffrahn, Jan Křečk · 1996 · Annals of the Entomological Society of America

   Resumen

   The generic status of the Greater Antillean smaller nasutes (all genera except Nasutitermes) is revised, paying special attention to anatomical characters of the workers. Two new monotypic genera, Caribitermes and Antillitermes, are created. Terrenitermes Spaeth, 1967, is synonymized with Parvitermes Emerson (in Snyder 1949). The following new combinations are proposed: Parvitermes aequalis (Snyder, 1924a) (formerly in Obtusitermes), Parvitermes antillarum (Holmgren, 1910) (formerly in Velocitermes), Parvitermes toussainti (Banks, 1919) (formerly in Terrenitermes), Caribitermes discolor (Banks, 1919) and Antillitermes subtilis (Scheffrahn & Křeček, 1993) (both formerly in Parvitermes). The 2 mainland species formerly assigned to Parvitermes should be removed from this genus: one resulting new combination is Velocitermes laticephalus (Snyder, 1926), whereas the actual taxonomic position of the species described as Parvitermes bacchanalis Mathews, 1977, remains unclear. With the exception of a Constrictotermes species present in Cuba, the smaller nasute fauna of the Greater Antilles and adjacent Bahamas and Virgin Islands now appears endemic to this region at the genus level. We hypothesize that an ancestor related to Obtusitermes diversified in the Greater Antilles and gave rise to all Parvitermes, Caribitermes and perhaps Antillitermes species.

2. Diverse Rhinotermitidae and Termitidae (Isoptera) in Dominican Amber

   Kumar Krishna, David A. Grimaldi · 2009 · American Museum Novitates

   Resumen

   The most diverse and best-preserved paleofauna of the higher termites heretofore known, all found in Miocene amber of the Dominican Republic, is described. The imago of Coptotermes priscus Emerson is redescribed, and the soldier of C. priscus, the first known fossil soldier of this genus, is described. The fauna includes the following 29 new species, all in existing genera, with Krishna and Grimaldi as authors of each: in the Rhinotermitidae, two new species based on imagoes of each—Coptotermes hirsutus and C. paleodominicanus; in the Termitidae, 23 new species based on imagoes—Amitermes lucidus, Anoplotermes bohio, A. cacique, A. carib, A. maboya, A. naboria, A. nitaino, A. quisqueya, A. taino, Atlantitermes antillea, A. caribea, A. magnoculus, Microcerotermes insulanus, M. setosus, Nasutitermes amplioculatus, N. incisus, N. magnocellus, N. medioculatus, N. pilosus, N. seminudus, Subulitermes hispaniola, S. insularis, and Termes primitivus; in the Nasutitermitinae four new species based on nasute soldiers—Caribitermes hispaniola, Nasutitermes rotundicephalus, Parvitermes longinasus, and Velocitermes bulbus. This brings the total termite fauna in Dominican amber to four families, 17 genera, and 39 species, a number that exceeds that of the present-day fauna of Hispaniola. Biogeographical, paleoecological, and phylogenetic implications of the Dominican amber termites are discussed.

3. Taxonomy, Distribution, and Notes on the Termites (Isoptera: Kalotermitidae, Rhinotermitidae, Termitidae) of Puerto Rico and the U.S. Virgin Islands

   Rudolf H. Scheffrahn, Susan C. Jones, Jan Křeček, James A. Chase, John R. Mangold, Nan‐Yao Su · 2003 · Annals of the Entomological Society of America

   Resumen

   Termite surveys from Buck, Culebra, Mona, Puerto Rico, St. Croix, St. John, St. Thomas, and Vieques islands yielded 1,564 colony samples from 274 sites. Twenty-one species were recorded including: Cryptotermes brevis, Cryptotermes havilandi, Cryptotermes rotundiceps, Cryptotermes undulans, Glyptotermes liberatus, Glyptotermes pubescens, Incisitermes bequaerti, Incisitermes furvus, Incisitermes incisus, Neotermes intracaulis n. sp., Neotermes mona, and Procryptotermes corniceps (Kalotermitidae); Coptotermes havilandi, Heterotermes sp., and Prorhinotermes simplex (Rhinotermitidae); and Anoplotermes n. sp. undescribed, Caribitermes discolor, Nasutitermes acajutlae, Nasutitermes costalis, Parvitermes wolcotti, and Termes hispaniolae (Termitidae). Of these, twelve are West Indian endemics, six have endemic ranges that include the tropical American mainland, and three are nonendemic pests. Distribution maps and keys based on the soldier caste and the winged imago are provided. Neotermes intracaulis, a new species from St. Croix, is described from the imago and soldier. Additional descriptions or redescriptions are given for G. liberatus (imago), I. incisus (imago and soldier), Ca. discolor (imago and soldier), and Pa. wolcotti (imago). An understanding of West Indian termite biogeography relies on current faunal distributions and the few fossil termites available from Hispaniola. Over-water dispersal of termites on flotsam is the most plausible mechanism for contemporary distributions, however, vicariate speciation cannot be discounted for species that are poor dispersalists. Faunal composition of Puerto Rican and the Virgin Islands termites suggest a biogeographical origin that is derived from both western and southern mainland sources.
