Studies on African Agama III. Resurrection of Agama Agama Turuensis Loveridge, 1932 (Squamata: Agamidae) from Synonymy and Elevation to Species Rank
Th e status of Agama agama turuensis SALAMANDRA 44 1 35-42 Rheinbach, 20 February 2008 ISSN 0036-3375 Studies on African Agama III. Resurrection of Agama agama turuensis Loveridge, 1932 (Squamata: Agamidae) from synonymy and elevation to species rank Philipp Wagner, Patrick Krause & Wolfgang Böhme Abstract. New material of Agama agama Linnaeus, 758 from Mount Hanang, Tanzania is indistingu- ishable from the type material of Agama agama turuensis Loveridge, 932, a taxon which is so far con- sidered to be a synonym of Agama lionotus elgonis Lönnberg, 922. Our comparative morphological study demonstrates turuensis is most similar to Agama mwanzae Loveridge, 923 and Agama kaimosae Loveridge, 935, and distinct from both A. agama and A. lionotus Boulenger, 896. Agama turuensis can likewise neither be assigned to A. mwanzae nor A. kaimosae but has to be rather considered as a dis- tinct species. Key words.

HERPETOLOGICAL JOURNAL, Vol. 11, pp. 101-108 (2001) • EFFECTS OF INCUBATION TEMPERATURE ON EMBRYONIC DEVELOPMENT AND SEX DETERMINATION IN THE NORTH AFRICAN AGAMID LIZARD, AGAMA IMPALEARIS EL HASSAN EL MOUDEN 1 , MOHAMMED ZNARI1 AND CLAUDE PIEAU2 1 Department of Biology, Faculty of Sciences, Cadi Ayyad Un iversity, PO Box 2390, Marrakech, Morocco 2lnstitut Jacques Monad, UMR 7592 CNRS et Un iversites Paris 6 et 7, 2, Place Jussieu, F- 75251 Paris Cedex 05, France The effects of temperature on incubation time, embryo survival, sex ratio , embryo growth and size at hatching were investigated in the north AfricanAgamid lizard, Agama impalearis. Seven constant temperature treatments (spanning 20-36°C) were employed and a split clutch design was used to assign eggs from the same clutch to the different treatments. Incubation time varied significantly with temperature treatments. Embryos incubated at 32°C, 34°C and 36°C hatched between 41 and 46 days, whereas embryos incubated at 26°C and 28°C hatched at 83 and 67 days respectively. Hatching success was higher at 28°C, 30°C, 32°C and 34°C, but much lower at 26°C and 36°C; hatching did not occur at 20°C. Eggs incubated at 26°C and 36°C produced only females. At 28°C, 30°C, 32°C and 34°C, the percentages of males were 9%, 53.5%, 32%, and 58% respectively. These sex ratios can be explained by a temperature-dependent mechanism of sex determination. The relative growth rates are highest early in incubation and lower for several days prior to hatching. -

Stellio' in Herpetology and a Comment on the Nomenclature and Taxonomy of Agamids of the Genus Agama (Sensu Lato) (Squamata: Sauria: Agamidae)
©Österreichische Gesellschaft für Herpetologie e.V., Wien, Austria, download unter www.biologiezentrum.at HERPETOZOA 8 (1/2): 3 - 9 Wien, 30. Juli 1995 A brief review of the origin and use of 'stellio' in herpetology and a comment on the nomenclature and taxonomy of agamids of the genus Agama (sensu lato) (Squamata: Sauria: Agamidae) Kurzübersicht über die Herkunft und Verwendung von "stellio" in der Herpetologie und Kommentar zur Nomenklatur und Taxonomie von Agamen, Gattung Agama (sensu lato) (Squamata: Sauria: Agamidae) KLAUS HENLE ABSTRACT The name 'stellio' has received a wide and variable application in herpetology. Its use antedates modern nomenclature. The name was applied mainly to various agamid and gekkonid species. In modern usage, confu- sion exists primarily with its use as a genus, i. e., Siellio. To solve this problem, STEJNEGER (1936) desig- nated Siellio saxatilis of LAURENTI, 1768 which is based on a figure in SEBA (1734) as the type species. This species is unidentifiable. In an unpublished thesis, MOODY (1980) split the genus Agama (s. 1.) into six genera. He overlooked STEJNEGER's (1936) designation and reused Stellio for the stellio-group of agamid lizards. Many authors followed MOODY (1980). Recently, some authors pointed out that Siellio is unavailable but did not fully dis- cuss the implications for agamid nomenclature. It is argued that a satisfactory nomenclature is difficult with current knowledge of agamid taxonomy. It is suggested to restrict Laudakia to L. tuberculata and to use Ploce- denna for the stellio-group (sensu stricto). KURZFASSUNG Der Name "stellio" sah eine breite und vielfältige Verwendung in der Herpetologie, die weit über die moderne Nomenklatur zurückreicht. -
The Herpetofauna of the Cubango, Cuito, and Lower Cuando River Catchments of South-Eastern Angola
Official journal website: Amphibian & Reptile Conservation amphibian-reptile-conservation.org 10(2) [Special Section]: 6–36 (e126). The herpetofauna of the Cubango, Cuito, and lower Cuando river catchments of south-eastern Angola 1,2,*Werner Conradie, 2Roger Bills, and 1,3William R. Branch 1Port Elizabeth Museum (Bayworld), P.O. Box 13147, Humewood 6013, SOUTH AFRICA 2South African Institute for Aquatic Bio- diversity, P/Bag 1015, Grahamstown 6140, SOUTH AFRICA 3Research Associate, Department of Zoology, P O Box 77000, Nelson Mandela Metropolitan University, Port Elizabeth 6031, SOUTH AFRICA Abstract.—Angola’s herpetofauna has been neglected for many years, but recent surveys have revealed unknown diversity and a consequent increase in the number of species recorded for the country. Most historical Angola surveys focused on the north-eastern and south-western parts of the country, with the south-east, now comprising the Kuando-Kubango Province, neglected. To address this gap a series of rapid biodiversity surveys of the upper Cubango-Okavango basin were conducted from 2012‒2015. This report presents the results of these surveys, together with a herpetological checklist of current and historical records for the Angolan drainage of the Cubango, Cuito, and Cuando Rivers. In summary 111 species are known from the region, comprising 38 snakes, 32 lizards, five chelonians, a single crocodile and 34 amphibians. The Cubango is the most western catchment and has the greatest herpetofaunal diversity (54 species). This is a reflection of both its easier access, and thus greatest number of historical records, and also the greater habitat and topographical diversity associated with the rocky headwaters. -

It is referred to (1) the aequatorialis series based on its moderate size and narrow toe lamellae, and (2) the eulaemus sub-group based on having a typical Anolis digit, in which the distal lamellae of phalanx III distinctly overlap the proximal subdigital scales of phalanx II. The new species is most similar morphologically to A. otongae and A. gemmosus, both from similar elevations on the western Andean slopes of Ecuador, but differs from these species in morphology and color patterns. We present a phylogeny based on DNA sequence data as additional evidence supporting delimitation of the new species. The new species and A. gemmosus are sister taxa within the “western Dactyloa clade.” Key words.

(Squamata: Iguania) from the Central Andes of Colombia
HERPETOLOGICAL JOURNAL 20: 231–236, 2010 A new species of Anolis of the aequatorialis group (Squamata: Iguania) from the central Andes of Colombia Julián Andrés Velasco1, Paul David A.

The new species, Anolis anoriensis, is similar to A. eulaemus Boulenger, which occurs in both the western and central Andes, and was positioned in the eulaemus subgroup of the aequatorialis group. Anolis anoriensis differs from A. eulaemus in having smaller interparietal scales and a green body coloration with a darker anterior part of the dewlap. We also for the first time describe the coloration of Anolis eulaemus, which is almost exclusively brown with a diffused light brown dewlap.
