Ctenomys dorsalis Thomas 1900

Holotype

“Female. Original Number 255. Collected 7th May, 1900” by John Graham Kerr ( Thomas 1900:285) ( Figures 1 and 2 ). The specimen is housed at the British Museum [Natural History Museum, London]. The date of collection was questioned by Contreras and Roig (1992), who suggested that J. G. Kerr had captured this species during his travels in 1889–1891 or 1896–1897. Contreras and Roig (1992) argued that the time period between the date of collection (7th May, 1900) and publication (before the year 1900 ended) was too short for the specimen to have made the trip from Paraguay to London. An additional fact is that J. G. Kerr was in London throughout 1900.

Type locality

Imprecisely as “Northern Chaco of Paraguay ” by Thomas (1900:285) in the original description; Contreras and Roig (1992), based on the itineraries of its collector, J. G. Kerr, suggested that its type locality is presumably located at the Department of Presidente Hayes (see discussion below) ( Figure 3 ).

Figure 3: Map of Paraguay and surroundings, showing the newly documented localities for CtenomYS dorSaliS (1 – Paraguay: Boqueron; Colonia Fernheim, 16 km W Filadelfia; and 2 – Paraguay: Boqueron; Colonia Mennonita, Orloff). Localities discussed by Contreras and Roig (1992) as possible type localities of this species include: 3 – Misión Inglesa, Waikhtlatingmalyalwa and 4 – a point between Las Juntas and Fortín Page. The dotted line corresponds to the limit between Bolivia and Paraguay according to the Treaty of Benítez-Ichazo (23th November 1894). The suggested distribution for this species proposed by Bidau (2015) is indicated in light blue (??). Landscape cover represents the ecoregions according to Olson et al. (2001).
