A new species of stygobitic cirolanid (Isopoda: Cirolanidae) from an anchialine cave on Abaco, the Bahamas (original) (raw)

A new genus of stygobitic/troglomorphic cirolanid (Isopoda: Cirolanidae) from a 'blue hole' cave in the Bahamas

2003

From an inland "blue hole" cave on Norman's Pond Cay (Exumas, Bahamas) one female specimen of a remarkable new stygobitic/ troglomorphic cirolanid has been caught, which is here described as Exumalana reptans n.g. n.sp. A combination of numerous characters, especially of antenna!, pereiopodal, pleopodal, and tail-fan morphology, distinguishes the new genus from all hypogean cirolanids already described, its affinities being for the time being unclear. Moreover, the behaviour of the new species seems to be original.

A new genus for Cirolana troglexuma Botosaneanu & Iliffe, 1997, an anchialine cave dwelling cirolanid isopod (Crustacea, Isopoda, Cirolanidae) from the Bahamas

Subterranean Biology, 2017

Cirolana troglexuma Botosaneanu & Iliffe, 1997 is redescribed and a Lucayalana Bruce & Brix, gen. n. established for the species. In total 38 specimens were collected from Hatchet Bay Cave, Eleuthera. Specimens on which previous records of L. troglexuma (from Exuma Cays, Cat Island, and Eleuthera) were based have been reexamined when possible. The diagnostic identifying characters and purported apomorphies for Lucayalana gen. n. are: frontal lamina short, narrow, less than 7% width of labrum, not extending to anterior margin of head; pleonite 3 extending posteriorly to posterior of pleonite 5, laterally overlapping pleonites 4 and 5; ventrally broad, forming a strong ventrally directed blade; pereopods 1-3 merus inferior margin RS not molariform. Mitochondrial COI and 16S loci and the nuclear 18S locus data show that all specimens are the one species. Comparison to additional cirolanid COI sequence data

Discovery of a third stygobitic species of Gnathostenetroididae (Isopoda Asellota), and additional information on some other stygobitic isopods (Cirolanidae) from the Caribbean

Neostenetroides magniezi, sp. nov. (male, female) is described from an unusual subterranean aquatic habitat, possibly anchialin, on the island of Mayaguana, Bahamas. This 3 rd described subterranean adapted species of a small family of Asellota, is compared with two previously described species from anchialine caves, respectively on San Salvador Island, Bahamas and on Cuba. Unpublished information (morphology, distribution) is made available for several Caribbean stygobiont Cirolanidae: Metacirolana mayana, Bahalana geracei, B. abacoana, B. yagerae, Cirolana (C.) troglexuma. RÉSUMÉ Neostenetroides magniezi, sp. nov. est décrit (mâle, femelle) d'un curieux habitat, peut-être anchialin, de Mayaguana, Bahamas. Cette 3 ème espèce stygobie connue d'une petite famille d'Asellota, est comparée avec les espèces congénériques déjà décrites d'une grotte anchialine de l'ile San Salvador (Bahamas) et, respectivement, d'une grotte anchialine de Cuba. On présente des données inédites (morphologie, distribution) sur plusieurs espèces de Cirolanidae stygobies des Caraïbes: Metacirolana mayana, Bahalana geracei, B. abacoana, B. yagerae, Cirolana (C.) troglexuma.

Four new stygobitic cirolanids (Crustacea: Isopoda) from the Caribbean - with remarks on intergeneric limits in some Cirolanids

1997

Four new stygobitic and troglomo phic cirolanids are described from various parts of the Caribbean. Cirolana (C.) troglexuma n. sp. is described from a cave on one of the Exuma Cays, Bahamas; two subgenera are recognized in g. Ciro/ana : sg. Cirolana including troglexuma as only presently known stygobitic species, and sg. Anopsilana equally well represented by subterranean and by epigean species. Hapto /ana bowmani n. sp. and H. belizana n. sp. inhabit caves of Yucatan and Belize, respectively; interesting ly, they are both abundantly different from the Cuban species of this stygobitic genus, showing more similarity with the species from Somalia a nd W. Australia. Jamaica/ana pleoscissa n. g. n. sp. was discovered in a cave from Jamaica; the new genus has affinities with Anopsilana and Bahalana, but a combination of characters-some of them highly orig inal-renders definition of a new genus necessary. Bahalana may ana BOWMAN should be removed from that genus, whereas Dodecalana yagerae Carpenter is an interesting species of Bahalana.

Two new stygobitic species of Cirolanidae (Isopoda) from deep cenotes in Yucatan

2000

Haptolana ytm ca n. sp. is the 6' 11 described species of an entirely hypogean-adapted genus. Cirolana (An opsilana) yucatana n. sp. is the 9' 11 described stygobitic and troglomorphic species in thi s subgenus. Both were discovered by diving in deep waters of cenotes in the Yucatan peninsul a, a region from whi ch five stygobitic cirolanid species were known. Jalllaicalana BOTOS ANEANU & ILIFFE, 1997, is sy nonymized with Ciro/ana (A nopsilana).

A new species of cirolanid isopod (Peracarida, Isopoda) collected from Cenote Aerolito, Cozumel Island, northwestern Caribbean

Crustaceana, 2015

A new species of Cirolana Leach, 1818, collected from Cenote Aerolito, Cozumel Island, Mexican Caribbean, is described. Cirolana (Anopsilana) adriani sp. nov. has a body 2.7× as long as wide, widest at pereonites 5-6; cephalon smooth, with small rostral point; pereonites without tubercles or ridges; antenna 2 not surpassing back of segment 2 of pereon; pleonite 4 lacking free ventrolateral margins; pleotelson as long as wide, smooth, with 9 distal robust setae; appendix masculina extremely long, 2× as long as endopod of pleopod 2. The main differences between the new species and the marine species Cirolana (Anopsilana) jonesi (Kensley, 1987) and C. (A.) sinu (Kensley & Schotte, 1994), as well as the stygobitic species C. (A.) yucatana Botosaneanu & Iliffe, 2000, the most similar known species of Cirolana (Anopsilana) in the region, are described. This is the second isopod of the genus Cirolana recorded from the karstic systems of the Yucatan Peninsula.

Arubolana Botosaneanu and Stock, 1979: a genus of stygobitic cirolanid isopods, with description of a new species from the Dominican Republic

Subterranean Biology, 2009

From Arubolana, a genus of entirely subterranean-adapted Cirolanidae, 3 species had been described, from subterranean aquatic habitats in Aruba, Bermuda, and Jamaica. A fourth species is described in the present paper (male, female) from a freshwater cave in the Dominican Republic. The species of Arubolana are well characterized by shared characters like the structure of the uniquely odd maxilla II and the subterminally inserted appendix masculina. From the ecological point of view, much diversity characterizes the species, which are either cave dwellers or interstitially living, marine, freshwater, or euryhaline. RÉSUMÉ 1 Dans Arubolana, genre de cirolanides entièrement adapté à la vie souterraine, 3 espèces ont été décrites d'habitats aquatiques souterrains d'Aruba, de Bermuda, et de la Jamaïque. Dans la présente publication une quatrième espèce est décrite (mâle, femelle) d'une grotte à eau douce de la République Dominicaine. Les espèces d'Arubolana sont toutes bien caractérisées par des caractères communs, comme la structure bien particulière de la seconde maxille et l'appendix masculina à insertion subterminale. Une grande diversité ećologique caractérise les espèces, qui sont cavernicoles ou interstitielles, marines, dulcicoles, ou bien euryhalines.

On a collection of stygobitic cirolanids (Isopoda: Cirolanidae) from Northern Mexico, with description of a new species

1998

From caves and springs in northern Mexico (Tamaulipas and Coahuila), mostly explored by diving, seven species of stygobitic and troglomorphic cirolanids were sampled: four species of Speocirolana BOLIVAR (one of them , interesting in several respects, described as new) , the two known species of Sphaerolana COLE & MI NCKLEY , and Cirolanides texensis BENEDICT. For all six already known species, • the localities are new, and additional information is provided on their morphology, variability, and relationships. With 15 described spec ies, Mexico has a quite remarkable and varied assemblage of subterranean Cirolanidae, pointing to quite diverse marine ancestors.
