Abstract Some contributions to the knowledge of the buthid scorpion genus Ananteris Thorell, 1891 in Colombia are herein presented, based upon the examination of over 100 specimens. Ananteris ochoai sp. nov. and Ananteris solimariae sp. nov. are described from Nariño and Santander departments, respectively. The recently described Ananteris hasshy Teruel & Roncallo, 2008 is synonymized under Ananteris columbiana Lourenço, 1991 based on several evidences from morphology. The males of Ananteris dorae Botero-Trujillo, 2008, Ananteris ehrlichi Lourenço, 1994 and Ananteris myriamae Botero-Trujillo, 2007, and the female of Ananteris arcadioi Botero-Trujillo, 2008 are described for the first time. Ananteris meridana González-Sponga, 2006 is reported for the first time for Colombia and the genus Ananteris for the departments of Cundinamarca, Santander and Norte de Santander. Likewise, new locality records are given for A. arcadioi, A. dorae and A. myriamae. Revised diagnoses and data on intraspecific variability are provided for A. arcadioi, A. columbiana, A. dorae, A. ehrlichi, A. meridana and A. myriamae. Hemispermatophore morphology is described for the first time for A. arcadioi, A. columbiana, A. dorae, A. ehrlichi, A. meridana, A. myriamae, A. ochoai sp. nov. and A. solimariae sp. nov., providing evidence of this structure’s taxonomic usefulness and revealing a paramount need to describe it in further taxonomic works on Ananteris. Some notes on the use of the fixed finger trichobothria for the definition of Ananteris species

are provided. A distribution map plotting the known locality records of the thirteen Colombian species of Ananteris and a key to their identification are also included. Finally, the name ‘Ananteris antioquensis’, used by Otero et al. (2004) but never published, is herein deemed a nomen nudum. Key words: Ananteris ochoai sp. nov., Ananteris solimariae sp. nov., Ananteris hasshy syn. nov., Ananteris antioquensis nomen nudum, hemispermatophore, trichobothria, Colombia

Resumen Se presentan algunas contribuciones al conocimiento del género Ananteris Thorell, 1891 en Colombia, con base en el estudio de más de 100 especímenes. Se describen Ananteris ochoai sp. nov. y Ananteris solimariae sp. nov. de los departamentos de Nariño y Santander, respectivamente. La recientemente descripta Ananteris hasshy Teruel & Roncallo, 2008 es sinonimizada con Ananteris columbiana Lourenço, 1991 con base en diversas evidencias morfológicas. Se describen por primera vez los machos de Ananteris dorae Botero-Trujillo, 2008, Ananteris ehrlichi Lourenço, 1994 y Ananteris myriamae Botero-Trujillo, 2007, así como la hembra de Ananteris arcadioi Botero-Trujillo, 2008. Se reporta por primera vez a Ananteris meridana González-Sponga, 2006 para Colombia y al género Ananteris para los departamentos de Cundinamarca, Santander y Norte de Santander. Asimismo, se dan nuevos registros de localidades para A. arcadioi, A. dorae y A. myriamae. Se proveen diagnosis revisadas e información sobre variabilidad intraespecífica para A. arcadioi, A. columbiana, A. dorae, A. ehrlichi, A. meridana y A. myriamae. Se describe por primera vez la morfología del hemiespermatóforo para A. arcadioi, A. columbiana, A. dorae, A. ehrlichi, A. meridana, A. myriamae, A. ochoai sp. nov. y A. solimariae sp. nov., mostrando evidencias de la utilidad taxonómica de esta estructura y revelando una imperante necesidad de describirla en futuros trabajos taxonómicos en Ananteris. Se presentan algunas notas acerca del uso de las tricobotrias del dedo fijo para la definición de especies de Ananteris. Se incluyen un mapa de distribución con todas las localidades donde han sido registradas las trece especies Colombianas de Ananteris y una clave para su identificación. Por último, el nombre ‘Ananteris antioquensis’, utilizado por Otero et al. (2004) pero nunca publicado, es aquí considerado un nomen nudum. Palabras clave: Ananteris ochoai sp. nov., Ananteris solimariae sp. nov., Ananteris hasshy syn. nov., Ananteris antioquensis nomen nudum, hemiespermatóforo, tricobotrias, Colombia

Introduction Ananteris Thorell, 1891 is a group of small-sized buthid scorpions with a primarily Neotropical distribution. This genus currently consists of 72 species known from Costa Rica southward through tropical South America to Paraguay, with the greatest number of species occurring in Venezuela (31 spp.), Brazil (20 spp.) and Colombia (11 spp.) (González-Sponga 2006; Kovařík 2006; Lourenço et al. 2006; Botero-Trujillo 2007, 2008a, 2009; Teruel & García 2007; Rojas-Runjaic et al. 2008; Teruel & Roncallo 2008; Giupponi et al. 2009; Lourenço et al. 2009; Lourenço & Duhem 2010; Botero-Trujillo & Noriega 2011). This genus also includes the species Ananteris feae (Borelli, 1911) from Guinea, Guinea-Bissau and Ivory Coast in tropical West Africa, originally assigned to the monotypic genus Ananteroides Borelli, 1911 but transferred to this genus by Lourenço (1985), who considered Ananteroides to be a synonym of Ananteris. A checklist of the species of Ananteris described up to 2007 and the countries where they are known from was made available by Rojas-Runjaic et al. (2008). Ananteris was first recorded in Colombia by Hummelinck (1940), who mentioned the collection of a juvenile female Ananteris cussinii Borelli, 1910 in the northern city of Riohacha—specimen that Flórez (2001a) and Botero-Trujillo (2008a) considered in need of revision. Subsequently, this genus was subject of various contributions that led to the eleven species that are known to date from this country (Lourenço & Flórez 1989; Lourenço 1991, 1994, 1999a; Botero-Trujillo 2007, 2008a, 2009; Teruel & García 2007; Teruel & Roncallo 2008), a number that may still be far from complete. Contrasting with the situation dominating Colombian scorpion collections some 10 years ago, when only very few specimens of Ananteris were known to exist, today many specimens are available, due to intensive fieldwork and recent revisions to different collections that have recovered previously undetected samples of this genus. The large number of Ananteris specimens now housed in Colombian collections and the continuous increment in the number of species occurring recently were the motivations for the present paper. This contribution is based on the examination of 119 specimens; among the material examined are the types for two new species, the first males known of Ananteris ehrlichi Lourenço, 1994, Ananteris myriamae Botero-Trujillo, 2007 and Ananteris dorae Bot-
