Gamasomorpha vianai Birabén, 1954: 196  , fig. 21a (Male holotype from Tigre, Buenos Aires, Argentina, 6-XI-1952, M. J. Viana, deposited in MACN PBI_ OON 25567View Materials, examined).

Diagnosis. This species can be recognized by the elongated abdomen, with the abdominal ventral scutum as long as wide ( Figs 10DView FIGURES 10, 11DView FIGURES 11, 14BView FIGURES 14). Males of the species resembles C. simplex  comb. rest. in the shape of the male palp, with the embolar distal process ending into an elongated tip bearing a short and broad undulate lamella ( Figs 13View FIGURES 13 G- I) but differs by the absence of strong paired hairs in the inner paturon of chelicera ( Figs 13AView FIGURES 13 ̅C). Females of this species can be recognized by the internal genitalia with narrow and triangular antero-lateral area ( Fig. 14HView FIGURES 14).

Description. Male ( PBI _ OON 25567View Materials). Carapace length 0.63; abdomen length 0.86. CEPHALOTHORAX: Carapace orange-brown, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, surface of elevated portion of pars cephalica granulate, sides granulate; lateral margin without denticles. Clypeus straight in front view, high, ALE separated from edge of carapace by their radius or more, around ALE diameter. Eyes ALE, PLE largest than PME; ALE separated by more than their diameter, PLE-PME separated by less than PME radius. Sternum orange-brown, fused to carapace, furrow with rows of small pits, surface finely punctuate, microsculpture medially and in furrows, anterior margin with semicircular depression in the middle half, posterior margin not extending posteriorly of coxae IV; setae originating from surface. Mouthparts: Chelicerae, endites and labium orange-brown. Chelicerae anterior face unmodified; retromargin without teeth; fangs without tooth-like projections; paturon inner margin with brush, laminate groove absent. Labium anterior margin indented at middle. Endites anteromedian part forming a groove between serrula and the apical portion. ABDOMEN: rounded posteriorly; dorsum soft portions pale white. Pedicel scuto-pedicel region with straight scutal ridge, plumose setae absent, with short weak ridge. Dorsal scutum orange-brown, middle surface reticulate, sides reticulate. Epigastric scutum anterior spiracles secondary openings at level of epigastric furrow on an indent. Postepigastric scutum orange-brown, almost semicircular, fused to epigastric scutum, with short posteriorly directed lateral apodemes, with clear seam at furrow. Spinneret scutum large. LEGS: orange-brown. GENITALIA: Epigastric region with sperm pore circular, situated in front of anterior spiracles, rebordered. Palp proximal segments orange-brown. Conductor narrowing towards end; distal tip with lamellar structure, subdistally downwards curved ( Figs 13H, JView FIGURES 13). Embolar tip with short embolar distal process; embolar prolateral process narrow with short and broad translucent dorsal area ( Figs 13HView FIGURES 13 ̅J).

Female ( PBI _ OON 25545View Materials). As in male except as noted. Total length: 1.56. CEPHALOTHORAX: Mouthparts: paturon inner margin with short inter-digitating setae. GENITALIA: internal genitalia V shaped, whit narrow and triangular lateral apodemes, protruding and narrow central area, receptaculum small and rounded ( Fig. 14HView FIGURES 14).
