Guinotia is a monotypic genus of freshwater crabs in the family Pseudothelphusidae,[1] containing only the species Guinotia dentata,[2] commonly known as cyrique.[3] They have few predators.[4] Found in the West Indies, they are easily caught[3] and thus are used locally as a food source.[5]
Description
Guinotia dentata is almost oval in shape and the teeth on its carapace are very small. It is a yellow-brown colour and its shell can grow to Шаблон:Convert long; it is about 3/5 long as wide.[3][5] The eyestalks are yellow whilst the corneas are black,[3] but they are probably best identifiable by their large yellow claws with straight sharply pointed fingers.[6]
The species sometimes has almost an entire dorsal surface of carapace yellow with submarginal brown.[7]
Its shell has a cervical meandering curve which does not quite touch the edge of the shell. About 24 cubicles are well defined. The forehead is low, excavated and depressed and of uniform height.[8] Its pereiopods are fairly average and its chelae are without prominent, swollen protuberance on outer surface near the base of the fingers.[7]
Distribution and habitat
The species is native mostly to Dominica, Guadeloupe, Martinique and Saint Lucia.[9] Its distribution is fragmented because of its presence on multiple islands, but it is plentiful in the regions it inhabits.[9]
Guinotia dentata lives mostly in streams (particularly shady ones)[4] and ponds and may sometimes be seen on land, though it avoids areas that are excessively dry.[1] It has not yet been observed in estuaries.[4] It lives in streams and rives in the highlands of the Lesser Antilles, not including the Virgin Islands.[9][10] They are known to hide under roots of trees, rocks and rotten wood where they dig shallow burrows which are oval in shape.[5][11] They have been spotted at altitudes of Шаблон:Convert.[3] They certainly inhabit the Boeri Lake and may inhabit Freshwater Lake.[12]
The largest threat to the species is habitat destruction, and a protected area has been established on Dominica to conserve them.[9]
Reproduction
Reproduction takes place entirely in fresh water, and breeding takes place all year round; there does not seem to be a breeding season.[4] The young undergo direct development, hatching as juveniles, without passing through any larval stages. The females carry the eggs and protect the young[5] who stay with their mother for a period after hatching.[4]
Diet
Guinotia dentata is a mainly carnivorous (though partially herbivorous)[5] animal which sometimes also acts as a scavenger or detritivore.[4] It has been observed to eat minnows, prawns, and aquatic algae-like vegetation.[13]
Taxonomic history
Guinotia dentata was first described in 1825 by Pierre André Latreille.[2] The specific epithet Шаблон:Lang means "toothed" in Latin.[4] In 1965, Gerhard Pretzmann erected the genus Guinotia (a tribute to Danièle Guinot) and made Latreille's species the type species.[14]
The following species were previously considered members of Guinotia:[2]
- Guinotia pestai Pretzmann, 1965 (now Eudaniela pestai)
- Guinotia rodriguezi Pretzmann, 1968 (now Microthelphusa rodriguezi)
