New cavernicolous Millipeds of the Family Cambalidae (Cambalidae: Spirostreptida) from Texas (U.S.A.) and Mexico., 1964,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Causey Nell B.
The cavernicoles include: (1) Cambala speobia (Chamberlin), troglobitic in central and southwest Texas; (2) C. reddelli reddelli n. sp. and subsp., troglophilic in west Texas and epigean in New Mexico; (3) C. reddelli inornatus n. subsp., troglobitic in northwest Texas; and (4) Mexicambala russelli n. gen. and sp., troglobitic in southern San Luis Potosi. They are described and figured, and a key is given.

The author examines two specimens of Nicoletia texensis Ulrich from the Quintero caves, Tamaulipas (Mexico). Among the most important characteristics of this species the exaggerated lengthening of the legs, cerci, antennae and other appendages has to be mentioned. Among Diplura, nearly the same degree of lengtheneing of the appendages may be observed in Plusiocampa dargilani (Moniez), a troglobitic Campodeidae of France. The structure of the median claw, completely different form other Nicoletia, probably will allow the institution of a new Genus for N. texensis.

Temperate preference responses of some aquatic, cave-adapted Crustaceans from Central Texas and Northeastern Mexico., 1973,

The temperature preference responses of five species of troglobite crustaceans were studied in a 15-30C gradient. Stygonectes hadenoecus, S. russelli and Asellus reddelli had no discernible temperature preferenda. Speocirolana bolivari had a weak preference for 20-30C. Cirolanides texensis had a pronounced preference for 20-30C, temperatures much warmer than that of its habitat. The lack of temperature preferenda in three species agrees with the hypothesis that imprisoned troglobites tend to lose responses to those environmental variables which are constant in caves. S. bolivari may retain its temperature selectivity because of a slow rate of cave-adaptation. It is hypothised that C. texensis is recently descended from a tropical, epigean, freshwater ancestor.

Description of the male of the Mexican cavernicolous Stenasellid Mexistenasellus parzefalli Magniez, 1972, from Huizache Cave, San-Luis Potosi State, Mexico. In the female with a brood pouch, the coxopodit of the maxilliped contains two provisional, oostegit-like plates, whereas the ovigerous female of european Stenase1lids have only the inner one. This temporary sexual female character is known in other Isopods, such as the cavernicolous Caecosphaeroma burgundum Dollfus.

During the past several years, members of the Association for Mexican Cave Studies have made some surprising additions to the knowledge of the invertebrate fauna of Mexico. None of their finds is more exciting than the species described here, a millipede much larger than the nearest epigean relative in an order outstanding for its scarcity of troglobitic adaptations. The absence of ocelli and the reduction of body pigment in the known epigean typhlobolellids suggest that they are deep humus dwellers preadapted for cave life.

Holsinger John R.
Paramexiweckelia, new genus, is described from a groundwater outlet in Cohauila, Mexico. The type-species, by monotypy, is Mexiweckelia particeps Holsinger. Based on the number of its plesiomorphic (ancestral) characters, this genus is the most primitive member of the family Hadziidae from the North American mainland.
