First registry of parthenogenesis in Centruroides gracilis (Latreille, 1804) (Scorpiones: Buthidae) Rolando Teruel Summary: Two cases of parthenogeneses observed in Centruroides are reported gracilis (Latreille, 1804) coming from the city of Santiago of Cuba. These represent the first registries of the occurrence of this reproductive strategy in this species of Buthidae. Key words: Scorpiones, Buthidae, Centruroides, parthenogenesis, Cuba. First record of parthenogenesis in Centruroides gracilis (Latreille 1804) (Scorpiones: Buthidae) Abstract: Two record of parthenogenesis plows herein given for Centruroides gracilis (Latreille 1804) from Santiago of Cuba City. These plows the first record of the occurrence of this reproductive strategy in this species of Buthidae. Key words: Scorpiones, Buthidae, Centruroides, parthenogenesis, Cuba. Introduction Between the species of American scorpions with ampler geographic distribution gracilis is without Centruroides doubts (Latreille 1804), knowing within the American continent established populations in Cuba, the USA, Mexico, Guatemala, Honduras, Panama, Colombia and Venezuela (Arms, 1988; Arms & Maes, 2000; Fet & Lowe, 2000; González-Sponga, 1996; Hoffmann, 1932; KovaÍík, 1998; Lourenço & Méndez, 1984; Sissom & Lourenço, 1987; Unpublished Teruel, 1997 []; Teruel & Stockwell, 2003). This scorpion exhibits sinantrópicos habits markedly, being in great abundance as much in cities and towns occupying the interior of the houses and the areas abiertas like waste baskets and barren lots (Teruel, 1997 [unpublished]) and thanks to which it has been introduced accidentally by the man in sites very separated from his natural area of distribution, like Canary Islands (Arms & Báez, 1988) and western Africa (Belfield, 1956). As far as its reproductive ecology, its postembryonic development and mating in captivity they have been studied by Arms & Hernandez (1981) and Francke & Jones (1982), but until the present has not registered the occurrence of parthenogenesis in this scorpion. Recently two cases of parthenogeneses have been observed that represent the first observations of the occurrence of this phenomenon in C. gracilis, whose details and meaning are discussed in the present note. Material and methods In captivity, the units were maintained in capsules of Petri of 50? 150 mm of diameter, in direct dependency as large as each scorpion. It was used as substrate paper of humid filter and the proportionate food ad libitum exclusively consisted of nymphs and adults of cockroaches (American Periplaneta, P. australasiae, germanic Blattella and Pycnoscellus surinamensis). The units are deposited in the personal collection of the author (RTO). Results First case: A youthful female of C. gracilis was captured in Caymans (western suburbs of the city of Santiago of Cuba) the 13 of January of 1988 by the author, brought to the laboratory and maintained it lives in captivity. This individual realised its last ecdisis by the end of October of that own year and having itself maintained isolated without contact with other scorpions, a litter of 19 larvae give birth the 15 of December of 1989 that realised his first dumb one to the six days (21 of December). As they became independent from the mother (who died 20 days after the childbirth), separated and they were maintained individually in capsules of Petri; 15 of them realised his the second dumb between the 3 of February and 9 of March of 1990 (the other four nymphs I died before carrying out this ecdisis). Only three nymphs II did his third and fourth ecdisis (of the 6-20 of April of 1990 and of the 3 of May to the 2 of June of 1990, respectively) and two of them carried out their villa and sixth dumb (17 of July to the 10 of August of 1990 and 3 of September from 1990 to the 13 of June of 1991, respectively), after which they emerged like adult females. The duration in days of each ninfal stage was the following one: nymph I (44-78), nymph II (34-56), nymph III (45-57), nymph IV (52-69) and nymph V (48-276); the complete subadult period lasted 262 and 514 days in cases both studied. Both females died in captivity few days after to have reached the adultez.
NOTE: In this case the female was a young adult and wild caught
