A new species of Ananteris Thorell, 1891 from Cordillera Central in Colombia, with some notes on the taxonomy of the genus (Scorpiones: Buthidae)

Abstract

A new species of Ananteris Thorell, 1891 is herein described from a single locality placed in the Cordillera Central of Colombia, which represents the first record of this genus for Tolima department. This new taxon exhibits several singular features, and apparently represents a relict population inside an urbanized area. Also, some aspects on the taxonomy of the genus are briefly discussed, and its diagnosis is emended. With this addition, the total of Ananteris species described from Colombia is raised to six.

Rare or poorly known scorpions from Colombia. III. On the taxonomy and distribution of Rhopalurus laticauda Thorell, 1876 (Scorpiones: Buthidae), with description of a new species of the genus

“…As a part of a joint research project on the systematics of Colombian scorpions, the junior author and some collaborators undertook some field work in several areas of northeast Colombia. This effort has already yielded several important discoveries of both undescribed and poorly known species (Teruel & García, 2007, 2008a, 2008bTeruel & Roncallo, 2007), including a few of specimens of the genus Rhopalurus from Riohacha which were at first referred to R. laticauda in the latter paper.…”

Rare or poorly known scorpions from Colombia. II. Redescription of Tityus columbianus (Thorell, 1876) (Scorpiones: Buthidae)

“…As a part of a joint research project on the systematics of Colombian scorpions, one of the authors (LFGH) and some of his collaborators undertook extensive field work in several areas of Colombia; an effort that has already yielded several important discoveries of both undescribed and poorly known species (Teruel & García, 2007a, 2007bTeruel & Roncallo, 2007; R. Teruel, L. F. García & C. A. Roncallo, unpublished data). Among them, 22 specimens of T. columbianus were collected in a locality from Boyacá Department, which represents a new record for this species.…”

“…Comparisons (adult males only): Ananteris hasshy sp. n. shares four interesting characters with Ananteris tolimana Teruel et García, 2007, from the Cordillera Central range: (1) four pairs of lateral eyes; (2) dorsolateral and lateral supramedian carinae of metasomal segments II-IV with the terminal granule enlarged and spiniform; (3) sternites III and V with a posteromedian smooth patch; (4) pedipalp fingers with six principal rows of granules, the basalmost row more than twice longer than the preceding. This Andean species can easily be disting- uished from the former by its larger size (26 mm), higher pectinal tooth count (22-23), noticeably more slender telson and pedipalp chelae, different structure of the smooth patch on sternite V (bulky and white-colored), pectines comparatively much larger, and a different pattern of pigmentation (sternites and metasoma much more densely spotted, pedipalps with trochanter much darker and densely spotted, but femur and patella lighter and less densely spotted).…”

“…The genus Ananteris Thorell, 1891 in Colombia has been the subject of recent attention from taxonomists, and its number of species known from the country increased continuously in 25 years from zero to five (Lourenço, 1982(Lourenço, , 1991(Lourenço, , 1994(Lourenço, , 1999Lourenço & Flórez, 1989;Botero-Trujillo, 2007). More recently Teruel & García (2007) described a sixth species which possesses a combination of very unique morphological characters previously unknown in this genus, such as the presence of four pairs of lateral eyes, dorsolateral and lateral supramedian carinae of metasomal segments II-IV with the terminal granule enlarged and spiniform, sternites III and V each with a posteromedian smooth patch, and pedipalp fingers with six principal rows of granules of which the basalmost row is more than twice longer than the preceding, among others.…”

“…As a part of a joint research project on the systematics of Colombian scorpions, a research team is conducting field work in several areas of northeast Colombia, an effort that has already yielded several important discoveries of both undescribed and poorly known species (Teruel & García, 2007, 2008a, 2008bTeruel & Roncallo, 2007, 2008. Among the material obtained, there is a single specimen of Ananteris, which was captured in northern Bolívar Department and represents a very distinctive new species of the genus, the seventh known from Colombia.…”
