Current Work in Herpetology:

Liolaemus qalaywa • An Endemic New Species of Andean Lizard of the Genus Liolaemus (Iguania: Liolaemidae) from southern Peru and Its Phylogenetic Position

J. C. Chaparro, A. J. Quiroz, L. Mamani, et al.

Abstract:

Integrative evidence of several external morphological characters and molecular phylogenetic analyses of mitochondrial DNA (12S, cyt-b) are used to place a new species of Andean lizard of the genus Liolaemus (Iguania: #Liolaemidae) in the Liolaemusmontanus group and as sister group of the clade formed by L. signifer. The new species is characterized by a unique combination of morphometric characteristics, scalation, and color pattern. The L. montanus group now contains seventeen species in southern Peru, distributed along the eastern and western slopes of the Andes.

Pterygosomatidae mites and Geckobia.

The mite family Pterigosomatidae are parasites of Arthropods and of lizards including geckos. The family are obligate parasites meaning they can’t survive independently of hosts and they’re ectoparasites because they live on the outside of their hosts.

These mites like other arachnids have appendages other than legs called chelicerae and pedipalps and can have 8 legs as well. Pterygosomatid mites can have bristles called setae and bodies that can be put into three parts called tagma. The Gnathosoma contains the mouth chelicerae and pedipalps. The podosoma/ contains the legs and the opisthosoma is at the posterior end.

In this family, Living mites in the genus Pimeliaphilus are parasites of Arthropods and the other genuses are parasites of lizards. There is an early Cretaceous amber fossil of a Pterygosomatid from France that is thought to belong to the genus Pimeliaphilus and this fossil mite may have fed on cockroaches. It is unknown if the family originally fed on Arthropods or lizards so they may have been feeding on lizards for over 100 million years.

One species Geckobelia stomii appears to be a parasite of iguanas. However G. stomii eggs have been found on a tick that is also a parasite of iguanas. It may be the case that this species is a parasite of the tick that is a parasite of green iguanas. This would make G stomii a hyper parasite (a parasite of a parasite). It may instead be the case that the mite is phoretic on the tick meaning that it is getting a lift on it.

Geckobia is a genus of Pterygosomatid mites that affects geckos in all three superfamilies (Gekkonoidea, Eublepharoidea and Pygopodoidea). Other genera can affect geckos though and Geckobia can also affect the Iguania family Liolaemidae and has ocassionly been found on tortoises. Geckobia mites feed on blood and lymph and can be red or orange. Geckobia mites can be found around the eyes ears and between the toes as well as around the groin area.

Some lizards can have folds in their skin called mite pockets where mites can be found. So lizard can have pockets. For example New Caledonian geckos can have mite pockets on their distal thighs. This just means on the part of their thighs closer to the knee than the start of their limb. Pterygosomatid mites in the genus Pterygosoma have been found in mite pocket like structures of a lizard in Agamidae a family that also includes bearded dragons and the Uromastyx.

NUEVA ESPECIE DE LAGARTIJA PARA CHILE CENTRAL

Descubierta por el Jaime Troncoso-Palacios, investigador de la U. de Chile, la nueva especie de lagarto fue encontrada en el sector cordillerano de la región de Valparaiso, a más de 3.000 m sobre el nivel del mar,

 Denominada Lioalaemus uniformis por la falta de un patrón dorsal y color uniforme encontrados para hombres y mujeres. La nueva especie podría haber sido confundida por varios años con Liolaemus monticola y Liolaemus belli. 

Vista de la localidad tipo de Liolaemus uniformis, un ambiente andino alto.

Liolaemus representa uno de los géneros de lagartos vivientes más diversos que se conocen, superando las 200 especies. Con una distribución que abarca gran parte de la superficie de Sudamérica, sus especies están adaptadas a una extraordinaria variedad de hábitats.
