description
Muma,
1986: 12-13, figs 30-34:
male holotype:
Total length, 22.0 mm.
LENGTH WIDTH
Chelicerae 5.2 mm
2.3 mm.
Propeltidium 2.3
4.2
Palpi
19.0
CL/CW=2.26
1st legs
10.0
PW/PL=1.83
4th legs 17.0
A/CP=7.60
Coloration in alcohol pale to rusty yellow with indistinct purplish
brown markings as follows: eye tubercle dark; propeltidium lightly dusky
except for a large, median, ovate, pale area; mesopeltidium,
metapeltidium and abdominal tergites reticulate dusky; abdominal pleura
pale; chelicerae, palpi and legs pale except for extreme distal end of
palpal metatarsus and tarsus which are lightly dusky; venter and
malleoli pale.
Structure similar to that of E.
andreasana but specifically different as indicated in measurements and
rations given above, figures 30 and 31 of the chelicera, and figure 32
of the abdominal ctenidia. There is no mesal tooth on the movable
finger of the chelicerae, the setal articulation area of the fixed
cheliceral finger occupies two-thirds of the length of the finger.
There is no palpal scopula, the ventral spine-like setae of the palpus
are too slender to count, and the palpal metatarsus is 3.3 times the
length of the tarsus.
female allotype:
Total length, 21.0 mm.
LENGTH WIDTH
Chelicerae 5.5 mm
2.1 mm.
Propeltidium 2.2
3.9
Palpi
15.0
CL/CW=2.62
1st legs
11.5 PW/PL=1.77
4th legs 19.5
A/CP=6.00
Coloration in alcohol similar to that of male but much more distinct.
Structure similar to that of E.
andreasana with specific differences as indicated in the measurements
and rations given above, figure 33 of the chelicerae, and figure 34 of
the opercula. There is no mesal tooth on the movable cheliceral
finger and there are 2 trace ctenidia on the first post-stigmatic
abdominal sternite.
