Williams, Jeffrey T. Phylogenetic Relationships and Revision of the Blenniid Fish Genus Scartichthys. Smithsonian Contributions to Zoology, number 492,30 pages, 20 figures, 4 tables, 1990.—Blenniid fishes of the genus Scartichthys Jordan and Evermann comprise a group of marine shore fishes restricted to the tropical and subtropical coasts of western Panama and western South America. Scartichthys comprises four species: S. crapulatus, new species (northern Chile and vicinity of Valparaiso), 5. gigas (Panama to northern Chile), S. variolatus (San Felix, San Ambrosio, and Juan Fernandez Islands), and S. viridis (vicinity of Valparaiso to southern Peru). The four species are quite similar ecologically in being herbivores and detritivores, and inhabiting rocky areas. The salariin genera Cirripectes Swainson, Scartichthys, Exallias Jordan and Evermann, Ophioblennius Gill, Pereulixia Smith, Stanulus Smith, Entomacrodus Gill, and Istiblennius Whitley form a monophyletic group within the tribe Salariini. My hypothesized phylogeny indicates that each of the following genera is the sister genus to the combination of all preceding genera: Scartichthys, Ophioblennius, Cirripectes, Exallias, Pereulixia, Stanulus, Entomacrodus, and Istiblennius (including at least the /. gibbifrons species complex). OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution's annual report, Smithsonian Year.

Phylogenetic relationships of the commercial marine shrimp family Penaeidae from Persian Gulf
Phylogenetic relationships among all described species (total of 5 taxa) of the shrimp genus Penaeus, were examined with nucleotide sequence data from portions of mitochondrial gene and cytochrome oxidase subunit I (COI). There are twelve commercial shrimp in the Iranian coastal waters. The reconstruction of the evolution phylogeny of these species is crucial in revealing stock identity that ca...

The genus Fritillaria comprises of 165 taxa of medicinal, ornamental and horticultural importance. Evolutionary relationships in this genus is an interesting research area, attracting many researchers. In this study, phylogenetic relationships among 18 native to endemic species in Iran belonging to four subgenera Petilium, Theresia, Rhinopetalum and Fritillaria, are assessed using chloroplast t...

Pseudocercospora species are plant pathogenic fungi occurring on a wide range of herbaceous and woody plants. Since its early description of the genus, its taxonomy has always been challenging. In recent years, Multi-gene DNA sequence data have provided sig...

Members of Nemacheilidae Family, Turcinoemacheilus genus were subjected to molecular phylogenetic analysis in this study. This genus was reported in 2009 to inhabit in Karoon River drainage, in contrary to previous assumption that it was the endemic species in the Basin of Tigris River. It was sampled from three stations placed in different tributaries in Karoon drainage and evaluated to unders...
