Liolaemus chacoensis (Chaco sand lizard). Predation.

Herpetological Review 48, 193-193.

Liolaemus chacoensis is distributed in the Chaco ecoregion from Paraguay to Argentina (Cei 1993. Reptiles del Noroeste y Este de la Argentina Herpetofauna de las Selvas Subtropicales, Puna y Pampas. Museo Regionale di Scienze Naturali. Torino. 949 pp.). Its biology is poorly known (Fitzgerald et al. 1999. J. Herpetol. 526–535; Pelegrin and Bucher. 2015. J. Nat. Hist. 49:2693–2708; but see the following for reproductive season: Cruz and Ramírez Pinilla 1996. Rev. Esp. Herpetol. 10:33–39). Herein we report an observation of a L. chacoensis being preyed up on by a scorpion.

At 1900 h on 19 June 2016, in La Majadita, Valle Fértil, San Juan Province, Argentina (30.70014°S, 67.49906°W, WGS 84; 978 m elev.), we discovered a juvenile female Liolaemus chacoensis (SLV = 39 mm) being preyed upon by a scorpion, Urophonius brachycentrus. The two were under a log, with the lizard, undigested, clutched in the scorpion’s pedipalps.

Primeros registros de Tityus trivittatus Kraepelin (Scorpiones, Buthidae) en el oeste Argentino [First records of Tityus trivittatus Kraepelin (Scorpiones, Buthidae) from western Argentina].

Multequina 11, 75-78.

The first records of the synantropic scorpion Tityus trivittatus (Buthidae) from the Argentinean provinces of San Juan and La Rioja are provided, representing the westernmost known localities of the species. Specimens were collected either in urban or periurban areas; it is suggested that this scorpion may be involved in an ongoing expansion process.
