Aegialomys Weksler, Percequillo & Voss 2006 View in CoL

The genus Aegialomys comprises four species, A. baroni (Allen 1897) , A. galapagoensis (Waterhouse 1839) (that includes A. bauri (Allen 1892)) , A. ica (Osgood 1944) , and A. xanthaeolus (Thomas 1894) , that inhabit the northern Trans-Andean South America, in a region that extends from central–southern Ecuador to Southern Peru, including in its range the Galapagos Archipelago ( Weksler et al. 2006; Prado & Percequillo 2013; Percequillo 2015a; Prado & Percequillo 2016; Prado & Percequillo 2018). Gardner & Patton (1976) described the karyotypes of A. bauri and A. xanthaeolus as essentially identical in all aspects (2n = 56, FN = 58). However, the same specimens karyotyped and identified as A. xanthaeolus by Gardner & Patton (1976) were recently reviewed by Prado & Percequillo (2016), highlighting that these specimens belong to A. baroni and A. ica . Moreover, as Prado & Percequillo (2018) synonymized A. bauri under A. galapagoensis , the karyotype of the former was attributed tentatively to the latter.

Karyotype: 2n = 56 and FN = 58. Autosomal complement: two small metacentric and submetacentric pairs, and 25 acrocentric pairs (one distinctly large and the remaining large to small decreasing in size). Sex chromosomes: X, a large acrocentric; Y, a small acrocentric ( Gardner & Patton 1976, pp. 6, Fig. 2D View FIGURE 2 ). The karyotypes of A. xanthaeolus was currently unknown.
