Glenognatha patriceae  new species

( Figs. 56View FIGURE 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 5987View MaterialsGoogleMaps  ; Paratypes: same data as the holotype, 4♂ 19♀ deposited in ICN 5986View MaterialsGoogleMaps  ; 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. 56CView FIGURE 56) and by the slender palpal tibia (longer than 1.5 times the maximum tibia width) ( Figs. 58 A, EView FIGURE 58). It can be distinguished from the former by the absence of scale-like projections in the embolus ( Figs. 58DView FIGURE 58, 59B –C) and from the latter by the thin distal projection of the conductor lamina ( Figs. 58B –CView FIGURE 58, 59B –C). Females can be easily distinguished from all other Glenognatha  species (except G. gaujoni  ) by the presence of cheliceral ectal apophysis ( Figs. 57D –FView FIGURE 57); distinguished from G. gaujoni  by the absence of anterior tooth ( Fig. 57DView FIGURE 57).

Male (holotype). Habitus as in Figures 56 A –DView FIGURE 56. 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.

Chelicerae slightly lighter than the cephalothorax and anteriorly projected ( Fig. 56BView FIGURE 56). Six promarginal and eight retromarginal teeth. Ret1 on the posterior surface ( Figs.View FIGURE 57
