Comparisons of specimens from the Gulf of Oman and India reveal consistent differences in the live colour of material from the rest of the Indo-West Pacific region, carapace (general form, shape of lateral teeth, position of longitudinal gastro-cardiac grooves, structures of posterior region), pterygostomian lobe, chela, male abdominal somite 6, male telson and Gl. Calappa exanthematosa is here recognised as a distinct species, redescribed, and illustrated.

In addition, one new genus and two new species of Diptilomi-opidae, namely Rhyncadicrus asperulus n. sp. et n. gen. from banana, Musa acuminata Colla x Musa balbisiana Colla (genomic group AAB) (Musaceae) and Catarhinus granatus n. sp. from Heliconia bihai L., are described and illustrated. The mites were collected in the State of Pernambuco, Northeastern Brazil. All were vagrants on the lower leaf surfaces of their host plants and no visible damage symptoms were observed.
查看更多>>摘要：The phylogenetic relationships of the Western Atlantic species of Bathygobius are inferred from DNA sequence data from two mitochondrial genes (cytochrome b, cytochrome c oxidase-I) and one nuclear gene (Recombination Activating Gene I). The phylogenyinferred from the concatenated dataset of the three genes uncovered the following major findings: (i) the Western Atlantic species of Bathygobius as a whole are not monophyletic; (ii) a well-supported monophyletic group containing B. soporator, B. lacertus and the Eastern Pacific B. andrei was recovered (termed the B. soporator group); (iii) a well-supported monophyletic group was recovered that contains B. curacao, the Eastern Pacific B. ramosus and B. lin-eatus, and B. antilliensis (termed the B. antilliensis group); (iv) the relationships between the several lineages of new world Bathygobius and some species of old world Bathygobius could not be resolved, and monophyly of a clade of all new world species could not be determined. The evolutionary history of the Western Atlantic species involves periods of diversification that occurred both before and after the closure of the Isthmus of Panama.
查看更多>>摘要：The Hemidactylus brookii group taxon has received increased attention in recent years from systematists and taxonomists attempting to unravel the complicated issues of its synonyms. In this study, a morphological approach is adopted to re-examine the syntypes of Hemidactylus brookii and Hemidactylus subtriedroides. The syntype series of H. brookii is found to be composed of two morphologically distinct species. A Borneo syntype is designated as lectotype and redescribed in detail to provide taxonomic and nomenclatural stability for the species. A syntype of H. subtriedroides is designated lectotype and also redescribed in detail, along with additional populations, which includes the Australian paralectotype of H. brookii sensu lato. Hemidactylus subtriedroides is morphologically distinct from H. brookii sensu stricto, but indistinguishable from the recently elevated synonym Hemidactylus tenkatei with which it is here considered a junior subjective synonym. Neotypes are designated for the two Pakistan synonyms, Hemidactylus kushmorensis and Hemidactylus gleadowi, which are redescribed and their specific validity proposed based on morphological characters. The four species are distinguished from all South and Southeast Asian congeners. The taxonomic status and complications of the remaining Asian H. brookii synonyms are discussed based on their original descriptions and other published literature. Furthermore, the literature and known specimens of Hemidactylus subtriedrus are reviewed, revealing a long history of taxonomic confusion associated with the name. It is here proposed to be a junior subjective synonym of Hemidactylus triedrus. The difficulties associated with relating morphological based taxonomy to previous molecular phylogenetic studies are discussed for this group.
