ETYMOLOGY: The specific name is a noun in apposition taken from the
type
locality.
DIAGNOSIS: This species seems closest to
G. marengo
but can be distinguished by the basally enlarged median prong on the median apophysis (fig. 546) of males, and the longer epigynal ducts (fig. 549) of females.
MALE: Total length 5.8. Coloration as in
G. marengo
. Leg spination: tibiae III v222. Retrolateral tibial apophysis bifid, with ventral prong hookshaped (fig. 547); median apophysis with long, basally widened medial prong (fig. 546).
FEMALE: Total length 6.5. Coloration as in
G. marengo
. Leg spination typical for genus. Epigynum wide, anterior onethird divided by septum (fig. 548); spermathecae each with anterior accessory lobe situated posterior of their tip (fig. 549).
