“…Additional work describing the sperm ultrastructure of the families Corytophanidae, Crotaphytidae, Hoplocercidae, Iguanidae, Opluridae, and Phrynosomatidae (Frost & Etheridge, 1989) are warranted and may cast light on the phylogenetic relationships of iguanians.…”

A detailed description of the sperm ultrastructure of Tropidurus semitaeniatus and T. torquatus is provided. Mature spermatozoa of T. semitaeniatus and T. torquatus are filiform and characterized by: apical portion of acrosome depressed; perforatorium single; epinuclear lucent zone well developed; midpiece short; mitochondria columnar; midpiece with three sets of alternating ring structures and mitochondria (rs1/m1, rs2/m2, rs3/m3); nuclear shoulders rounded; nucleus elongate; fibres 3 and 8 enlarged; and fibrous sheath in midpiece. Spermatozoa ofTropidurus are unusual in possessing a unilateral electron-lucent ridge at the surface of the acrosome and an epinuclear electron-lucent zone. The two species are very similar, differing in details such as degree of acrosome flattening, presence of bulging at nuclear base, and arrangement of microtubules in the endpiece. Comparisons between Tropiduridae and other families of iguanian lizards are made.

“…Iguania is a monophyletic assemblage of nine families of squamate reptiles whose phylogenetics relationships are poorly understood (Frost & Etheridge, 1989). Studies on the sperm ultrastructure have been carried out in five families of iguanians: Chamaeleonidae, Iguanidae, Phrynosomatidae, Polychrotidae, and Tropiduridae.…”

Comments: Hoplocercinae (Macey et al, 1997a) was selected over several older names for the same clade: hoplocercines (Smith et al, 1973), morunasaurines (Estes and Price, 1973), morunasaurs (Etheridge and de Queiroz, 1988), and Hoplocercidae (Frost and Etheridge, 1989).…”

Hoplocercinae includes 11 currently recognized species assigned to three taxa traditionally ranked as genera: Enyalioides cofanorum, E. heterolepis, E. laticeps, E. microlepis, E. oshaughnessyi, E. palpebralis, E. praestabilis, Hoplocercus spinosus, Morunasaurus annularis, M. groi, and M. peruvianus.…”

“…It is possible that a related genus of anole, Phenacosaurus, also may be derived from within the genus Anolis (Williams, 1989) but we are unable to address that question with the present data set. Morphological data do not support the recognition of Chamaelinorops as a valid genus, and Chamaeleolis is supported by only two characters (Frost and Etheridge, 1989).…”

Abstract-The realization that the present day positions of continents and island arcs are a result of continental drift led to the proposal that the extant West Indian fauna reflect an ancient (Cretaceous) land connection between the proto-Antilles and North and South America. Movements of the Antillean islands throughout the Cenozoic are hypothesized to have further fragmented the fauna present on the protoAntilles when it separated from the mainland 70-80 million years ago. This proposed vicariant origin of the West Indian fauna challenged the previous theory that some or most of the fauna arrived in the Antilles by overwater dispersal from mainland sources. The virtual absence of appropriate fossils in the West Indies has hampered testing these alternative hypotheses for the origin of the present day West Indian fauna.We present evidence from two types of molecular data, one providing indirect estimates of amino acid sequence divergence for the protein serum albumin, and the other direct DNA sequence information from a mitochondrial ribosomal RNA gene. Our new data provide insights into the origin and relationships of two enigmatic lizard genera, Chamae/eo/is and Chamae/inorops, and suggest they are recent derivatives within' the genus Ana/is. These data, along with molecular data presented elsewhere, strongly implicate an origin by overwater dispersal for most of the Antillean vertebrate fauna.
