The Virgin Islands (except St. Croix) are geologically part of the Puerto Rico Bank and biologically related to Puerto Rico, but their cockroaches (Dictyoptera: Blattaria) were not yet as well studied as those on Puerto Rico. To elucidate the number of species, life history, range distribution, and seasonal abundance of these cockroaches, we have c...

... those of Puerto Rico ( Heatwole et al. 1981). Politically these islands are divided into the British Virgin Islands (BVI) and U. S. Virgin Islands (USVI). There are two annual rainfall peaks in the Virgin Islands (Lazell 2005). Guana Island is a small, privately owned, BVI island located off the northeast end of Tortola at 18º28'N by 64º35'W ( Fig. 1). Its rugged topography of 297 hectares features exceptionally well-preserved subtropical dry forest that covers most of the island from sea level to its highest elevation (Sugarloaf Peak at 246 m). Since 2000 we have been studying the ecology and diversity of Virgin Island cockroaches (Dictyoptera: Blattaria), using Guana Island as our ...

Another unique feature is that the tegmina meet in a straight line down the back, overlap less than other cockroaches. Plectoptera infulata is a new record and second species in the genus from the Virgin Islands.

The world species of the genus Exoryza (Hymenoptera, Braconidae, Microgastrinae) are revised. Ten species are recognized, including five new, authored by Fernandez-Triana: mariabustosae, richardashleyi, ritaashleyae, rosamatarritae and yeimycedenoae. The species Dolichogenidea oryzae Walker, 1994 is considered as related to Exoryza - although is no...

To study the species number, habitat, behaviour, and life history, phasmids were collected either with a sweep net from vegetation, handpicked at white or ultraviolet lights, or searched for at night with flashlights. Additionally, a Malaise trap was set up on the leeward Quail Dove Ghut of Guana Island since 1999 (Lu et al., 2014), as well as another one on the windward North Bay since 2009 when we began quantitatively checking for the total number of stick insects every month by species and trap location in five annual periods of XI.2009-X.2010, XI.2010-X.2011, ...

The typical body pattern of many cockroaches is functionally related to their natural history, but it has variations reflecting the characteristics of their environment. The goal of this work is the evaluation of the relationship between morphological characteristics and climatic ecological niche in 10 species of the genus Eurycotis, all endemism of Cuba. I used 68 photographs of individuals on which 16 landmarks were placed in the left wing, pronotum and epiprocto, as well as in 10 locations of the main body. For the analysis of body shape, the Procrustes distances, centroid size, sum of Euclidean distances and sum of weight matrix were used as variables. For body sizes, length and width of pronotum, distance between wings, length of thorax, length and width of abdomen, and total body length were measured. Values of bioclimatic variables related to temperature and precipitation were also obtained, using the coordinates of the locality of collection of each individual. Each morphometric and climatic niche variables were described and correlated. It was found that the warmest climates species were E. taurus and E. cribosa, while E. torquinensis inhabits zones of lower temperature. The most distinct species from the rest in terms of absolute linear dimensions were E. taurus, as the largest, and E. perezassoi, as the smallest. In the analysis of the shape, a group of species with marked similarities was shown, except in the shape of the epiprocto. In addition, an association was found between the size of the species and the climatic niche, however, the environmental variables and the shape did not present any statistical association.

Blaberoidea, comprised of Ectobiidae and Blaberidae, is the most speciose cockroach clade and exhibits immense variation in life history strategies. We analysed the phylogeny of Blaberoidea using four mitochondrial and three nuclear genes from 99 blaberoid taxa. Blaberoidea (excl. Anaplectidae) and Blaberidae were recovered as monophyletic, but Ectobiidae was not; Attaphilinae is deeply subordinate in Blattellinae and herein abandoned. Our results, together with those from other recent phylogenetic studies, show that the structuring of Blaberoidea in Blaberidae, Pseudophyllodromiidae stat. rev., Ectobiidae stat. rev., Blattellidae stat. rev., and Nyctiboridae stat. rev. (with "ectobiid" subfamilies raised to family rank) represents a sound basis for further development of Blaberoidea systematics. Relationships in Blaberidae are widely incongruent with current classification, but more congruent with geographic distribution, with large Afrotropical, Neotropical, and Indo-Malayan clades. We further investigate evolutionary trends and correlations of various life history traits: wing development, body size, microhabitat, mating pattern, ootheca handling, and clutch size.
