Locality.- Argentina, Provincia de Entre Ríos, Departamento La Paz, RutaProvincial Nº 6, 8.5 km east from Colonia Máximo Castro (30°53'45'' S; 59°34'43'' W) (Fig. 1). An adult female found under fallen tree bark next to the route. Date: 23/08/2009. Col: Cajade R. and C. Falcione. Deposited in the Herpetological Collection of Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" (MACN 40270).

Comments.- The genus Taeniophallus Cope comprises a group of small terrestrial dipsadids, ranging from Guyana and Colombia to Argentina (Myers and Cadle, 1994). Taeniophallus poecilopogon occurs in southern Brazil, Paraguay, Argentina, and Uruguay (Koslowsky, 1898; Devincenzi, 1925; Peters and Orejas Miranda, 1970; Myers, 1974; Abalos and Mischis, 1975; Di Bernardo and Lema, 1987; Di Bernardo, 1992; Cei, 1993; Gonzáles and Hamilton, 1998; Achaval-Elena, 2001; Giraudo, 2001; Giraudo and Scrocchi, 2002; Achaval and Olmos, 2003; Carreira et al., 2005). Taeniophallus poecilopogon was rediscovered in Argentina after 143 years in the provinces of Buenos Aires (Nenda and Di-Pietro, 2009) and Corrientes (Etchepare and Zaracho, 2009). Additional reliable record for the country, also supported by voucher specimen deposited in a herpetological collection, comes from Buenos Aires province (Jan and Sordelli, 1866). There are three other records of the species for the country that are considered doubtful. Berg (1898) mentioned two specimens of T. poecilopogon of uncertain origin. One of these specimens possibly came from Entre Ríos (collected by Adolfo Doering 25 years before the publication of Berg´s paper) and apparently was housed in the Herpetological Collection of the Museo Argentino de Ciencias Naturales "Bernardino Rivadavia", MACN. The other specimen came from Corrientes or Misiones provinces, housed in the "Gabinete de Historia Natural de la Universidad". Unfortunately ongoing curatorial efforts on both collections failed to find the specimens and they should be considered lost for the time being (Nenda and Di-Pietro, 2009; and this study). Freiberg (1939) reported Taeniophallus poecilopogon for Entre Ríos province, without reference to a voucher specimen, and possibly referring to the material mentioned by Berg (1989).

In the present contribution we report the first specimen of Taeniophallus poecilopogon from Entre Ríos province, with voucher specimen and complete data. Bilateral scale counts are separated by a solidus as right/left. Specimen MACN 40270 (Fig. 2) has 485 mm of body length, 108 mm tail length representing 18% of total length, has 17 smooth dorsal scales without reduction and without apical pits, 168 ventrals, cloacal plate divided, 71+1 subcaudals, 6/7 supralabials 3th and 4th entering the orbit, 1/1 loreals in contact with second supralabial, nine infralabials in the right side (six of them in contact with chin shields) and eight infralabials in the left side (five in contact with chin shields), one preocular and two postoculars, and 1+2 temporal scales.


Figure 2. Taeniophallus poecilopogon (MACN 40270) in life from Entre Ríos province, Argentina. A: lateral view, B: dorsal and ventral view.

The collected specimen was kept in captivity for 38 days and during this period it fed on frogs, such as Pseudopaludicola falcipes and Scinax nasicus, and lizards, such as Cercosaura schreibersi. Di Bernardo and Lema (1987) reported that one specimen of Taeniophallus poecilopogon also fed on Cercosaura schreibersi, but it didn't show interest to eat offered frogs such as Scinax fuscovaria, Physalaemus lisei, and Elachistocleis bicolor. Etchepare and Zaracho (2009) also found skin and limbs that belonged to Dendropsophus sp. in the stomach of a road kill specimen from Corrientes province. The locality where specimen MACN 40270 was collected is a rural zone that belongs to the Ñandubay district in the Espinal phytogeographic province (Cabrera, 1976). This district is characterized by a semixeric forest, with Prosopis affinis (Ñandubay) and Prosopis nigra as predominating species, and also by palm trees such as Butia yatay and Thritrinax campestris. The ambient where the collected specimen was found, correspond to a patch of this semixeric forest modified by livestock activity.

ACKNOWLEDGEMENTS
