Based on 18S-rDNA sequences of 97 isopods including 18 Sphaeromatidea, we show Sphaeromatidae, Valvifera, Serolidae, and Ancinidae is a well supported clade. The within clade relationships of these taxa are not as definitively demonstrated because taxon sampling for some groups is still limited. In our analyses the Sphaeromatidae are shown to be unequivocally monophyletic. This is contrary to t...

the materials of this study were collected from intertidal and shallow subtidal habitats of the hengam island coasts from may 2013 to may 2014. a total of 10 species representing eight genera and four families are reported as follows: sphaeromopsis persikolpos khalaji-pirbalouty and wägele 2009, s. sarii khalaji-pirbalouty and wägele 2009, sphaeroma khalijfarsi khalaji-pirbalouty and wägele 201...

Exosphaeromaamplicauda (Stimpson, 1857) from the west coast of North America is reviewed and redescribed and revealed to be a group of closely related species. A neotype is designated and the species redescribed based on the neotype and topotypic specimens. Exosphaeromaamplicauda is known only from the coast of California, at Marin, Sonoma and San Mateo Counties. Exosphaeromaaphrodita (Boone, 1...

Dynoides elegans (Boone, 1923) from southern California is reviewed, redescribed, and figured. The original species description did not include figures, making it difficult to attribute individuals to the species. Dynoides saldanai Carvacho and Haasmann, 1984 and Dynoides crenulatus Carvacho & Haasman, 1984 from the Pacific Coast of Mexico and Dynoides brevicornis Kussakin & Malyutina, 1987, fr...

Zoological collections are major treasures representing the history of animal biodiversity on Earth and an important resource for conservation research. The Canadian Museum Nature (CMN) has one oldest crustacean in North America. Here, we provide illustrated catalogue superfamily Sphaeromatoidea Latreille, 1825, deposited Nature’s Crustacea Collection (CMNC). In this paper, report 18 species, b...
