Evolutionary transitions from terrestrial to aquatic life modify selective forces on an animal's coloration. For example, light penetrates differently through water than air, and a new suite of predators and visual backgrounds changes the targets of selection. We suggest that an aquatic animal's coloration may also affect its susceptibility to algal fouling. In a colour-polymorphic field popula...

Using a combination of fixed morphological character differences, mitochondrial DNA sequence data, and an estimate of phylogeny as our guide, we describe a new species of bent-toed gekkonid lizard (Genus: Cyrtodactylus) from southwestern Mindanao Island, and northeastern portions of the Sulu Archipelago, southern Philippines. The new species resembles C. annulatus, but differs from this and all...

background : the aim of this study was to investigate the ‘acaricidal effect' of zataria multiflora and ar­temisia annua essential oils on rhipicephalus (boophilus) annulatus . methods: this study was carried out in 2009 in the laboratory of parasitology of the faculty of veteri­nary medicine of shahrekord  university, west central iran. six dilutions (5, 10, 20, 40, 60 and 80 µl/cm 3 ) of both...

A new species of Stenolemus Signoret, 1858, Stenolemus annulatus sp. nov. (Reduviidae: Emesinae) is described from India. This new species is closely related to S. susainathani Wygodzinsky from Nilgiri Hills, South India and S. larat Wygodzinsky from Moluccas, Larat, by sharing common characteristics such as the ratio of distance between eyes and their width, long antennal first segment, slight...

A revision of the genus Thyreocephalus Guérin-Méneville, 1844 of Africa south of the Sahara is presented. A new genus Afrus gen. nov. was described with the type species Thyreocephalus spegazzinii Bernhauer, 1915, which resulted in following new combination: Afrus spegazzinii (Bernhauer, 1915), comb. nov. Eulissus collarti (Cameron, 1932) was transferred to Afrus. Based on a revision of types a...
