Glenognatha globosa (Petrunkevitch, 1925)

( Figs. 60–64 View FIGURE 60 View FIGURE 61 View FIGURE 62 View FIGURE 63 View FIGURE 64 , 132 View FIGURE 132 )

Cyrtognatha globosa Petrunkevitch, 1925a: 123 , fig. 42 (female holotype from San Lorenzo, Panama, 4.xii.1924, A. & W. Petrunkevitch leg., deposited in YPM, examined through photographs of the habitus and female genitalia). Glenognatha globosa: Dimitrov & Hormiga, 2009: 102 , figs. 66 A –F; Cabra-García et al. 2014: 1029, figs. 1I, 2J, 7H, 9G–H; World Spider Catalog 2015.

Diagnosis. Males of G. globosa resemble those of G. gaujoni and G. patriceae by the presence of thin pleural bars between coxae II–III ( Fig. 60C View FIGURE 60 ) and by the slender palpal tibia (longer than 1.5 times the maximum tibia width) ( Figs. 62 A, E View FIGURE 62 ). It can be distinguished from the former by the absence of scale-like projections in the embolus ( Fig. 64B View FIGURE 64 ) and from the latter by the absence of a thin distal projection in the conductor lamina ( Figs. 62B View FIGURE 62 , 64 A View FIGURE 64 ). Females can be easily distinguished from all other Glenognatha species (except G. gaujoni ) by the presence of anterior tooth ( Fig. 61D View FIGURE 61 ); distinguished from G. gaujoni by the absence of CFO ( Fig. 61D–E View FIGURE 61 ) and by having at least six retromarginal teeth ( Fig. 61F View FIGURE 61 ).

Description. Male ( ICN 5991) (Note: the male is here described for the first time). Habitus as in Figures 60 A – D View FIGURE 60 . Carapace brown, darker along furrows and with a well-marked fovea. Sternum brown, darker on sides. Abdomen oval, dorsally with irregular pattern of two longitudinal dusky bands on sides and thin transverse bands on the posterior region. Silver guanine spots scattered in dorsal and lateral surfaces. Venter with a pale black median band that ramifies towards lateral surface from the tracheal spiracle and the spinnerets. Silver guanine spots scattered in pale bands between the tracheal spiracle and the epigastric furrow. Legs yellow-brownish. Tracheal spiracle well-sclerotized. Pleural bars between coxae I–II, II–III and III–IV. Total length 3.70. Cephalothorax 1.70 long, 1.40 wide, 1.02 high. Abdomen 2.12 long, 1.45 wide, 1.35 high. Sternum 0.90 long, 0.85 wide.
