Etymology.—Refers to the type locality, In Ko
Diagnosis.—This member of the
group is a member of the kraepelini series as defined by Muma &
Brookhart (1988). It is the only member of this group without
ctenidia. Most members of this series are pale but have some dusky
to dusky purple markings.
inkopaensis is entirely pale in both the male and female.
holotype: total length 21, cheliceral length 5.4, cheliceral
width 2.2, propeltidium length 2.6, propeltidium width 5.2, palpus
length 14, first leg length 16, fourth leg length 27. Ratios: A/CP
7.04, CL/CW 2.6, PL/PW 0.5, FL/FW 1.0, CW/FFW 5.2. Coloration cream
yellow in all aspects of chelicera, propeltidium and appendages.
Malleoli white. Cheliceral FF with low, inconspicuous ridge on basal
aspect of FF. No teeth ventrally. MF with large PT but only a low
ridge anteriorally, small posterior IT separate from PT, tiny AT,
MST absent (some paratypes have tiny MST). Fondal teeth graded I,
III, II, IV. Fondal notch equal length to width. Mesoventral groove
deep, median in position expanding ventrally near the tip (Figs. 6 &
7). Flagellum complex typical of group, no ctenidia, no palpal
papillae. Male paratypes (6): total length 20–26, cheliceral
length 5.5–6.4, cheliceral width 2.2–2.9, propeltidum length
2.3–3.1, propeltidium width 4.4–4.9, palpus length 17.5–22.0, first
leg length 16.0–18.0, fourth leg length 22.0–29.0. Ratios: A/CP
6.5–8.0, CL/CW 2.2–2.9, PL/PW 0.52–0.67, FL/FW 0.7–1.0, CW/FFW
Female allotype: total length 22, cheliceral length
6.2, cheliceral width 2.2, propeltidium length 2.1, propeltidum
width 3.9, palpus 16.5, first leg length 12.5, fourth leg length
21.0. Ratios: A/CP 4.3, CL/CW 2.8, PL/PW 0.74 GOL/GOW 0.82.
Coloration is the same as the males. Chelicera typical of the group,
FF with large PT and MT, smaller AT, two IT between PT and MT, one
IT between IT and AT, MF with large PT and medium AT, two smaller
IT, MST absent (Fig. 8). Genital opercula with broad anterior arms,
recurved medial margin, short, curved wings, posterior margin
straight (Fig. 9). The allotype but not the paratype with four tiny,
thin ctenidia. Female paratype (1): total length 31,
cheliceral length 6.8, cheliceral width 2.2, propeltidium length
3.7, propeltidium width 5.5, palpus length 19.5, first leg length
16.5, fourth leg length 26.0. Ratios: A/CP 5.96, CL/CW 2.6,
PL/PW 0.65, GOL/GOW 0.76.
nine specimens of Eremobates inkopahensis were collected in
mid-March to early April indicating an early maturity. Eremobates
gracilidens Muma 1951 is also found in southern California in
Inyo and San Bernardino counties. The two females are shorter legged
then E. gracilidens based on the A/CP ratio. The genital
opercula are typical of the group although the anterior arms are
broader than in other members of this group.
