Chamäleons die unbekannten Wesen: Vorstellung von Rhampholeon acuminatus.

Chamaeleo, Mitteilungsblatt Nr. 37 der AG Chamäleons in  der DGHT. 18 (2): 30-33.

Volltext

Zusammenfassung:

Dieser skurrile Vertreter der kontinentalafrikanischen Stummelschwanzchamäleons wurde – nachdem er schon einige Jahre vorher im Internet und als „Montane  Pigmy Chameleon“ auf einem Poster von Joe BERADUCCI zu bewundern war – erst 2006 von Jean MARIAUX und Colin TILBURY als Rhampholeon acuminatus beschrieben und der Untergattung Rhinodigitum zugeordnet. Der Name leitet sich vom lateinischen „acuminare“ (schärfen) ab und bezieht sich auf die vielen spitzen, scharfkantigen Tuberkelschuppen auf Kopf und Körper der Tiere.

Es folgen Abschnitte über die Verbreitung, Merkmale, Fortpflanzung und Gefährdung.

MARIAUX, J. & TILBURY, C. R. (2006)

The pygmy chameleons of the eastern Arc range (Tanzania): Evolutionary relationships and the description of three new species of Rhampholeon (Sauria: Chamaeleonidae).

Herpetological Journal 16 (3): 315-331.

Volltext

Abstract:

The pygmy chameleons of the Eastern Arc Range forests in Tanzania are reviewed on the basis of  known  and newly  collected material. Two new species be longing to Rhampholeon (Rhinodigitum) and one to Rh. (Rhampholeon) from the Pare, Nguru and Mahenge Mountains are described. The status and distribution of the other species known in the area are reviewed, and an identification key is provided. The phylogenetic relationships between these taxa are discussed on the basis of small and large mt-rDNA subunits sequences and the relative importance of some morphological characters is evaluated. Hypotheses about the evolution of the group in the area are presented.

A review of  the systematics of the genus Bradypodion (Sauria: Chamaeleonidae), with the description of two new genera.

Zootaxa 1363: 23–38. ISSN1175-5334 (online edition) 

Abstract:

The taxonomic history and composition of the genus Bradypodion as construed by Klaver & Böhme (1986) and new morphological and molecular data relevant to the taxonomy of the group is reviewed. The combined evidence strongly supports a formal rearrangement of the group into three distinct genera. Bradypodion, type species Chamaeleo pumilus Daudin 1802, is retained for the southern African species. Two new genera are erected to accommodate additional well-diagnosed clades within central and east African species previously referred to Bradypodion. Species of the “fischeri complex” are assigned to Kinyongia gen. nova, whilst the endemic Mulanje chameleon is placed in the monotypic genus Nadzikambia gen. nova.

The two-horned chamaeleons of East Africa.

Zoological Journal of the Linnean Society 152 (2): 367–391, https://doi.org/10.1111/j.1096-3642.2007.00332.x

Abstract:

There have been numerous attempts to resolve the taxonomy of the two-horned chamaeleons of East Africa. However, the high levels of intraspecific variation and reported sympatry of morphologically distinct taxa indicate that their current classification is unsatisfactory. Tissue samples were collected from specimens from most mountain massifs (excluding the Nguu) where two-horned chamaeleons are known to occur and were used to sequence partial 12S and 16S rRNA, as well as ND2 mtDNA genes. These specimens and further museum material were used to review morphological variation and to define discriminating characters for each taxon. Phylogenetic analyses of gene sequences show clear genetic divergence between allopatric populations, although two lineages occur in sympatry in the East Usambara Mountains, and is supported by divergent morphology. In light of these results a formal revision of the taxonomy of all East African two-horned chamaeleons is proposed and seven species are recognized (Kinyongia boehmei, K. fischeri, K. matschiei, K. multituberculata, K. tavetana, K. uluguruensis and K. vosseleri). These taxa form a monophyletic group except for K. uluguruensis, which seems to be more closely related to one-horned species. Most of these taxa have been previously described and subsequently reduced to synonyms. Two other previously described two-horned taxa are not recognized as valid: Chamaeleo tornieri is considered species inquiriendae, and C. fischeri werneri is placed in synonymy with K. multituberculata. A dichotomous key is provided for the identification of these taxa and some aspects of their conservation, ecology and evolutionary origins are also discussed.

ROELKE, C. E. & SMITH, E. N. (2010)

Herpetofauna, Parc National des Volcans, North Province, Republic of Rwanda.

Check List 6 (4): 525-531. Jan. 2010. DOI: 10.15560/6.4.525

Abstract:

Herein is presented a list of the reptiles and anurans from the Parc National des Volcans (PNV)(01°43’ S, 29°52’ W), an area in the west and north provinces of the Republic of Rwanda in the Albertine Rift region of Africa.  Fieldwork was conducted between two and six days per week from June through August 2007 and 2008. We also conducted literature searches of all historical expeditions within the park for species records. Seventeen species of reptiles and anurans are recorded from the PNV. Nine of the species were anurans, distributed in five families: Arthroleptidae (3), Bufonidae (1), Hyperoliidae (3), Phrynobatrachidae (1), and Pipidae (1). Eight species of reptiles were recorded from five families: Chamaeleonidae (1), Lacertidae (2), Scincidae (2), Colubridae (2), and Viperidae (1). Eight of the seventeen species found in the PNV are endemic to the Albertine Rift.

A new bush anole (Iguanidae, Polychrotinae, Polychrus) from the upper Marañon basin, Peru, with a redescription of Polychrus peruvianus (Noble, 1924) and additional information on Polychrus gutturosus Berthold, 1845.

ZooKeys 141 : 79–107, doi: 10.3897/zookeys.141.1678.

Abstract:

We herein describe a new colorful species of Polychrus with a conspicuous sexual dimorphism from the dry forest of the northern portion of Región de La Libertad, Peru. The new species differs from all other Polychrus species, in that this species has very small dorsal scales and thus a higher number of scales around midbody and in the middorsal line from behind the occipital scales to the level of the posterior edge of the thigh. Furthermore, we redescribe Polychrus peruvianus whose original description is short and lacks information on intraspecific variation and sexual dimorphism. Also, we add some information on intraspecific variation and ecology of Polychrus gutturosus. Finally, we synonymize Polychrus spurrelli Boulenger with Polychrus gutturosus.

A new species of the Agama agama group (Squamata: Agamidae) from western Kenya, East Africa, with comments on Agama lionotus Boulenger, 1896.

Russian Journal of Herpetology 12 (2): 143-150

Abstract:

We describe a new species of Agama from westernmost Kenya. It is a member of the Agama agama species group characterized by small size (males up to 89 mm snout-vent length and 245 mm total length) and a unique male breeding coloration: flame- to scarlet-red head, neck and forelimbs, jet- or velvetly-black body, hindlimbs and tail root, and again a scarlet-red tail the terminal third of which is again black. Morphologically, the new species is similar to A. planiceps from southwestern Africa but has a much less depressed body. It also resembles typical A. agama from West and Central Africa, but is much smaller, less stoutly built and differently colored.

It is strikingly different from the two parapatric species of the Agama agama group, viz. A. caudospinosa and A. mwanzae, and differs also considerably from the sympatric representatives of the Agama agama complex itself: from the geographically neighboring A. a. elgonis and A. a. lionotus. We provide evidence that the latter taxon deserves full species rank and that the other East African subspecies of A. agama (i.e., elgonis, dodomae,  usambarae, ufipae) should be subordinated under a full species Agama lionotus.
