Terrestrial Isopods from Sri Lanka II: Exalloniscus brincki n. sp. (Crustacea, Malacostraca)

New Terrestrial Isopods of the Genus Miktoniscus from Eastern United States (Crustacea: Isopoda: Oniscoidea)

Wolbachia in Neotropical terrestrial isopods.

Despite Wolbachia being widespread among terrestrial isopods, studies on this symbiotic relationship are still incipient in the Neotropical region. The aims of the present study were to investigate the presence and prevalence of Wolbachia in natural populations of terrestrial isopod species in South America, and to analyze the diversity and phylogenetic relationships of Wolbachia strains. A tot...

Sri Lanka is a country with an approximate area of 66 thousand square kilometers (UNO, 2008). The population is 20,409,946 and the sex ratio (men per hundred women) is 98 (UNO, 2009). The proportion of the population under the age of 18 years is 28% and the proportion above age 60 is 8% (UNO, 2009). The literacy rate is 97% for men and 99% for women (UN Statistics, 2008). The life expectancy at...

Marine Isopods from the Lesser Antilles and Colombia (crustacea: Peracarida)

-Records of shallow-water marine isopods from Colombia, Tobago, and Dominica are listed. These are derived from recent collections as well as from published records. Several new species are described: Joeropsis tobagoensis, Munna caprinsula, Anopsilana sinu, Paraimene charlesae (the second known species in the genus), Pseudocerceis latistylis (the first record of the genus in the Atlantic), Sph...

Histological studies on the marsupium of two terrestrial isopods (Crustacea, Isopoda, Oniscidea)

The marsupium, a brood pouch in peracarid crustaceans (Crustacea, Malacostraca) has evolved in terrestrial environment for providing nutrition and optimal conditions for embryogenesis. In the present study we give details on the histology and ultrastructure of its constituting elements such as oostegites and cotyledons. Marsupia of two different eco-morphological types of woodlice, namely the n...
