Muma, 1986: 8-9, figs 17-22
MALE HOLOTYPE: Type length 34.0
Coloration in alcohol pale to dark
yellow with dusky purplish markings as follows: chelicerae with a
pair of dorsal dusky stripes; eye tubercle dark; propeltidium
reticulate dusky, darker at margins, a pair of light ovate areas
beside the eye tubercle, and a narrow, clear yellow mesal stripe;
mesopeltidium, metapeltidium, and abdominal tergites reticulate
dusky; palpal and leg markings somewhat faded but palpus apparently
pale on tarsus and dusky on metatarsus, and fourth leg apparently
dusky apically on femur and basally on tibia; malleoli white.
Dentition as shown in figures 17 and 18. Anterior tooth apparently
reduced to a low ridge; fondal notch sub-triangular in form, 1.6
times the basal width of the fixed finger, and with 2 to 4 minute
denticules; mesal tooth distinct.
Mesal groove of fixed finger typical of genus, narrow distally and
dilated basally. Flagellum complex typical of genus. Mesal setae of
movable finger plumose dorsally but simple ventrally. Palpal scopula
composed of about 200 small papillae, 10 on tarsus, and 190 on most
of metatarsus. Ctenidia on first post-stigmatic abdominal sternite
as shown in figure 19.
FEMALE ALLOTYPE: Total length 37.0
Coloration in alcohol almost identical
with that of the male except that the pleura of the abdomen are also
Dentition as shown in figures 20 and 21. Mesal tooth distinct. Mesal
setae of movable cheliceral finger plumose dorsally and simple
Structure typical of the genus and similar to that of the male except
that there is no palpal scopula and there are no ctenidia on the first
post-stigmatic abdominal sternite. Genital opercula as shown in figure

placed this species in its own species-group "because of its large size, the
absence or reduction of the anterior tooth on the male movable cheliceral
finger and the distinctive female genital opercula".
