Gothus is a genus of crab in the family Xanthidae, known from the Indo-West Pacific. The genus comprises two species, Gothus consobrinus and the type Gothus teemo .

Contents

Etymology

Gothus is named after the game of Go, referencing the similarity of the carapace patterns and granules with a Go board and stones. The suffix -thus is common in xanthid genera. [1]

Description

Individuals of Gothus are small crabs of less than 10 millimetres (0.39 in) of carapace width. The carapace is vibrantly colored, [2] and covered in small, round granules and tufts of setae. The regions of the carapace are clearly defined, with the front divided by a V-shaped notch. The anterolateral margin of the carapace bears four teeth on each side, where the first is flattened and not always clearly defined. [3] Gothus has been described as closest morphologically to Rhizaltus , although the latter's carapace does not show defined teeth. [4]

Taxonomy

The genus Gothus comprises two known species. The type species, Gothus teemo, was described alongside the genus. The other species, Gothus consobrinus, was originally described as Actaea consobrina in 1873, [5] before being transferred to Actaeodes in 1967. [6] Molecular phylogeny confirms that the two species form a clade. [2]

Inside Xanthidae, the genus has tentatively been placed in the subfamily Euxanthinae, although molecular phylogeny has questioned the monophyly of the subfamily. The position of Gothus is not stable, with the genus variously clustering with Liomerinae or with Xanthias and parts of Euxanthinae depending on the analysis. [2]

Distribution and habitat

Species in the genus are known to inhabit crevices inside shallow coral reefs. G. consobrinus was originally described from Upolu in modern-day Samoa, [5] and is widely known from the Indo-West Pacific. [7] Specimens have been reported in Japan, the Philippines, Vietnam and Australia, among other places. [6] G. teemo has only been found in the Paracel and Spratly Islands of the South China Sea. [8]

<span class="mw-page-title-main">Xanthidae</span> Family of crabs

Xanthidae is a family of crabs known as gorilla crabs, mud crabs, pebble crabs or rubble crabs. Xanthid crabs are often brightly coloured and are highly poisonous, containing toxins which are not destroyed by cooking and for which no antidote is known. The toxins are similar to the tetrodotoxin and saxitoxin produced by puffer fish, and may be produced by bacteria in the genus Vibrio living in symbiosis with the crabs, mostly V. alginolyticus and V. parahaemolyticus.

<i>Dyspanopeus sayi</i> Species of crab

Dyspanopeus sayi is a species of mud crab that is native to the Atlantic coast of North America. It has also become established outside its native range, living in Swansea Docks since 1960, the Mediterranean Sea since the 1970s, the North Sea since 2007 and the Black Sea since 2010. It can reach a carapace width of 20 mm (0.8 in), and has black tips to its unequal claws. It feeds on bivalves and barnacles, and is in turn eaten by predators including the Atlantic blue crab, Callinectes sapidus. Eggs are produced from spring to autumn, the offspring reach sexual maturity the following summer, and individuals can live for up to two years. The closest relative of D. sayi is D. texanus, which lives in the Gulf of Mexico; the two species differ in subtle features of the genitalia and the last pair of walking legs.
