Glenognatha patriceae Cabra-García & Brescovit, 2016, new species

Glenognatha patriceae new species

(Figs. 56 –59, 132)

Types. Male holotype from Hacienda San Pedro, Alto Queremal, Dagua, Valle del Cauca, Colombia, 3º29´N, 76º42´W, elev. 1800m, 21.ix.2009, J. Cabra leg., deposited in ICN 5987; Paratypes: same data as the holotype, 4♂ 19♀ deposited in ICN 5986; 1♂ 1♀ deposited in IBSP 163858.

Etymology. The species epithet is in memory of the first author’s mother, Patricia García Pinilla. The name is a noun in genitive.

Diagnosis. Males of G. patriceae resemble those of G. gaujoni and G. globosa by the presence of thin pleural bars between coxae II–III (Fig. 56C) and by the slender palpal tibia (longer than 1.5 times the maximum tibia width) (Figs. 58 A, E). It can be distinguished from the former by the absence of scale-like projections in the embolus (Figs. 58D, 59B–C) and from the latter by the thin distal projection of the conductor lamina (Figs. 58B–C, 59B–C). Females can be easily distinguished from all other Glenognatha species (except G. gaujoni) by the presence of cheliceral ectal apophysis (Figs. 57D–F); distinguished from G. gaujoni by the absence of anterior tooth (Fig. 57D).

Male (holotype). Habitus as in Figures 56 A –D. Carapace pale brown, darker along furrows. Sternum pale brown, darker on sides. Abdomen oval, dorsally with irregular pattern of two longitudinal dusky bands on sides. Silver guanine spots scattered in two median longitudinal bands and on lateral surfaces. Venter with a pale black median band and two lateral lighter bands with scattered silver guanine spots. Legs yellow-brownish. Tracheal spiracle well-sclerotized. Pleural bars between coxae I–II, II–III and III–IV. Total length 3.6. Cephalothorax 1.75 long, 1.30 wide, 0.90 high. Abdomen 2.15 long, 1.55 wide, 1.45 high. Sternum 0.90 long, 0.90 wide.
