Ferreira.   Diagnosis.Males of  Tropicosa baguala  sp. nov.are recognizable by the large, spoon-shaped tegular lobe with three marginal ridges ( Fig. 5a, b, g); the broad, triangular ventral process of median apophysis and by the absence of a subterminal apophysis ( Fig. 5e, h). Females can be recognized by the short, parallel triangular hoods of the epigynum ( Figs 1a, b, 2c) and by the wider median septum ( Fig. 1d).   Description. Male. Holotype(MCTP 18040).Color in ethanol ( Fig. 6a‒g): Carapace brown, covered by short white bristles except on the longitudinal median band. Longitudinal median band yellow, uniform towards the back ( Fig. 6a). Ocular area black, covered with dense white bristles; pars cephalicacovered by sparse, large white bristles ( Fig. 6b, d). Chillum membranous, divided by a sclerotized mesal portion. Cheliceral basal condyle large, cheliceral fang with no protrusion. Sternum yellow and longer than wide, covered by short, black, and sparse bristles ( Fig. 6e). Labium darker at the base, endites and labium clearer in their distal portion. Legs: all segments background yellow except femora, which have irregular stripes ( Fig. 6c). Opisthosoma all covered by tiny white bristles and sparse black bristles; dorsum olive with a yellow heart mark flanked by two dark, irregular stripes. Chevron marks among the heart mark and spinnerets ( Fig. 6a). Group of strong, curved, white and black bristles covering the dorsal anterior part, near the prosoma. Venter yellow, sparsely covered by black bristles and black dots; anterior spinnerets thicker and darker than posterior ones; all spinnerets cylindrical ( Fig. 5i). Cymbium piriform with a bunch of setae apically ( Fig. 5b). Subtegulum short and rounded, curved sperm ducts clearly visible. Ventral process of median apophysis triangular and pointed ( Fig. 4d); median apophysis curved apically ( Figs 4a, 5b). Terminal apophysis hyaline, curved and with almost the same width along its entire length ( Fig. 4b). Palea rounded, expanded, and partially sclerotized ( Fig. 5e, h). Embolus slender, tip hidden in ventral view, visible in apical view ( Fig. 5h). Tegular lobe broad, with three irregular protuberances ( Fig. 5g).   FIGURE 1.  Tropicosa baguala  sp. nov., female genitalia (MCTP 18025), aepigyne, ventral view, bvulva, dorsal view, cepigyne, lateral view, depigyne, anterior view, eepigyne, posterior view.
