Eremobates becki Muma 1986

Eremobates becki ►Muma, 1986: 7-8, fig. 16; ► Muma, 1987*: 8, fig. 16; ► Vázquez Rojas, 1995: 31; Vázquez Rojas, 1996e: 76; ►Brookhart and Brookhart, 2006: 305.

HOLOTYPE: MÉxico. Chihuahua: Colonia Garcia, 19 July 1931 (D. Eldon Beck), 1 male (holotype). Deposited in the collection of Brigham Young University, Provo, Utah. 

ORIGINAL DESCRIPTION:
Muma, 1986: 7-8, fig. 16:

male holotype: Total length, 18.5 mm.

                            LENGTH         WIDTH
Chelicerae         5.5 mm.            2.9 mm.
Propeltidium    2.9                     3.9
Palpi                   18.0                  CL/CW=1.90
1st legs               13.5                  PL/PW=1.34
4th legs              24.5                     A/CP=6.66

        Coloration in alcohol obscure.  The specimen has dried out at one time had has been recovered.  There are no distinct markings on the appendages or the abdomen.  The propeltidium is dark along the anterior margin and apparently distinctly dusky on the anterior half. .
       Structure essentially the same as that of E. angustus Muma and E. cruzi Muma except that the anterior tooth of the movable cheliceral finger is distinctly tooth-like, the fondal notch is quadrangular, slightly wider than long, and only slightly narrower or wider than the fixed finger.  Figure 16 shows the cheliceral dentition.  The above measurements and ratios are also distinctive except for that of length; the abdomen is shriveled.

Fig. 16,  Eremobates becki Muma, left chelicera of male,ectal view.  Redrawn from Muma (1986).

SUBSEQUENT ACCOUNTS:
 Muma, 1987: 8, fig. 16: Duplicates  above decscription, without added content.

DISTRIBUTION: Mexico. Chihuahua: Colonia Garcia.

PUBLISHED RECORDS: Known only from the type.

nOTES: Muma (1986,1987) noted that there is no scopula on the male palpus, and no discernable ctenidia on the first post-stigmatic abdominal sternite of the male.  He noted that E. angustus and. E. cruzi, the two previously described species of this group, have the fondal notch triangular in form, distinctly longer than wide, and much wider than the base of the fixed cheliceral finger. He reported that the ECCS have been broken off of both chelicerae of the holotype and cannot be illustrated. Vázquez Rojas (1995) included this species in a list of the solifuges of Mexico. Brookhart and Brookhart (2006) included this species in their annotated checklist of continental North American Solifugae, noting that it was known only from the type.
