| Summary: | Gulocosa gen. n. Type species: Gulocosa eskovi sp. n. Etymology. We continue the tradition of naming wolf spider genera by combining the name of a predatory vertebrate as the first element and ending with –cosa (or -osa) (cf. Cameron 2005; Marusik & Kovblyuk 2011), typical for lycosid genera (e.g. Arctos - Arctosa, Mustela - Mustelicosa, Lynx - Lynxosa, Pantera pardus - Pardosa). The generic name is derived from the scientific name of the wolverine (Gulo gulo) and ends with -cosa. The gender is masculine. Diagnosis. Gulocosa gen. n. differs from most Acantholycosa species (exception A. baltoroi (Caporiacco, 1935)), all Sibirocosa and Melecosa gen. n. by having 4 pairs of ventral spines on leg I (Fig. 3). Acantolycosa baltoroi differs from G. eskovi sp. n. by having no epigynal fovea, longer embolus and shape of fovea. Gulocosa gen. n. differs from Mongolicosa, which have 4 pairs of ventral spines on tibia I. The new genus can be distinguished by a thick embolus (Figs 9, 14, 16, 23‒ 27), high apical arm of the tegular apophysis (Figs 7 ‒8, 13, 22), septal stem, in which the anterior part extends the epigynal fovea (Figs 28, 30); thin embolus (Figs 51‒53); apical arm of tegular apophysis not larger than basal arm (Fig. 51); entire septal stem within epigynal fovea (Figs 54‒55) in Mongolicosa and undivided apical pocket (one apical pocket in Gulocosa gen. n. but two hoods or two apical pockets in Mongolicosa). Male palps in the new genus differ from similar Sibirocosa by the tegular apophysis with a well-developed apical arm (Aa; reduced in Sibirocosa) and short and wide (as long as wide) embolus (Em; longer than wide in Sibirocosa) (Figs 8, 10). Females of the new genus are most similar to those of Mongolicosa glupovi Marusik, Azarkina & Koponen, 2004 (Marusik et al. 2004: 136, figs 201, 208 ‒ 212) by having a similar septum (Se). These two species can be separated by the apical pocket (undivided in G. eskovi sp. n. and with two hoods in M. glupovi) and the shape of the fovea (wider than long in the new ... |
