Eremobates lapazi Muma 1986

Eremobates lapazi Muma, 1986: 8-9, figs 17-22; Muma, 1987: 9-10, figs 17-22; Vázquez Rojas, 1995: 31; Vázquez Rojas, 1996e: 76; Brookhart and Brookhart, 2006: 305.

HOLOTYPE: Male holotype and female allotype from 10 mi.NW of La Paz, Baja California, Mexico on October 6, 1941 by Ross and Bohart, deposited in the collection of the California Academy of Sciences, San Francisco, California.

Original description:
Eremobates lapazi Muma, 1986: 8-9, figs 17-22

MALE HOLOTYPE: Type length 34.0 mm.

  Length Width
Chelicerae 8.8 mm. 4.5 mm.
Propeltidium 4.7 6.5
Palpus 28.0  CL/CW=1.96
Leg 1 24.0 PW/PL=1.38
Leg 4 38.0 A/CP=6.66

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 mm.

  Length Width
Chelicerae 7.8 mm 4.7 mm.
Propeltidium 4.4 9.9
Palpi 23.0 CL/CW=1.66
Leg 1 21.0 PW/PL=2.25
Leg 4 32.0 A/CP=6.22

Coloration in alcohol almost identical with that of the male except that the pleura of the abdomen are also dusky.
Dentition as shown in figures 20 and 21. Mesal tooth distinct. Mesal setae of movable cheliceral finger plumose dorsally and simple ventrally.
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 22.

Figs. 17-22 (redrawn from Muma 1989): 17. Right male chelicera, ectal view; 18. Right male chelicera, mesal view.; 19. Male abdominal ctenidia, ventral view; 20. Right female chelicera, ectal view; 21. Right female chelicera, mesal view; 22. Female opercula, ventral view.

 SUBSEQUENT ACCOUNTS:
Muma, 1987: 9-10, figs 17-22: Re-publication of Muma (1986).

Vázquez Rojas, 1995: 31;

Vázquez Rojas, 1996e: 76;

Brookhart and Brookhart, 2006: 305.

DISTRIBUTION:

PUBLISHED RECORds:

nOTES: Muma (1986) 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".
