—Key foundational elements of taxonomic description were omitted in the original naming of species-group taxa now recognized in the Malagasy genus Nesomys: N. rufus Peters, 1870, N. audeberti (Jentink, 1879), and N. lambertoni G. Grandidier, 1928. Based on our review of the material available to the authors, we identified the holotype by monotypy of N. rufus, designated lectotypes of N. audeber...

SYNOPSIS Suuwassea emilieae is a recently described dinosaur taxon discovered in the Upper JurassicMorrisonFormationof thewesternUnitedStatesand theonlynon-diplodocidflagellicaudatan (Dinosauria: Sauropoda) known fromNorth America. It retains sauropod symplesiomorphies that are unexpected in a Late Jurassic taxon and thus sheds light on the evolutionary origins of the Flagellicaudata. Despite b...

In the current study, we review the taxonomic status of Liolaemus nigromaculatus. Despite being the nominal species of the nigromaculatus group and being the second species of the genus Liolaemus that was described, this species is of uncertain type locality and its true identification is a matter of discussion. After carefully analyzing several digital pictures of the holotype (juvenile male),...

The male holotype of CuZex (CuZex) bihamatus Edwards 1926 is redescribed, the male genitalia illustrated and its affinity as determined from comparative studies of genitalia of related species in the Sitiens group is discussed. In the preliminary study of the type material of Oriental CuZex at the British Museum (Natural History), I have also examined for comparative purposes the types of a num...

Ityphilus calinus Chamberlin, 1957 (Chilopoda: Geophilomorpha, Ballophilidae), a poorly known centipede from Cauca Valley, Colombia, is herein redescribed and illustrated after the male holotype, revealing the condition of the forcipular tarsungulum (which is completely smooth), also giving new data on many other morphological features of specific value until now unknown. A new diminutive speci...

The recent discovery of a new species of land iguana in the Galapagos (Tzika et al. 2008; Gentile et al. 2009; Gentile & Snell 2009) is indeed an exciting novelty, of great interest to all zoologists and evolutionary biologists. This species being apparently represented only by a very small population with a very limited range, it was described as a new taxon following an unusual procedure: no ...

William John Macleay (1882) described Serranus magnificus from the holotype collected by Andrew Goldie in Port Moresby, Papua New Guinea. The holotype was originally in the Macleay Museum, but was subsequently transferred to the Australian Museum (AMS) in 1907, along with around 500 additional lots of mostly Goldie New Guinea and “Chevert” expedition fishes (AMS series I.9039–I.9198, I.9200–I.9...

Very little information exists relevant to the species grouping and phylogenetic relationships of the opossum genus Monodelphis Burnett. Of the clearly distinct named species, the least information is available for M. unistriata (Wagner), one of the world's most poorly known species of mammals. Extant specimens consist of the Brazilian holotype of a skin now without a skull and dating from almo...
