Ammotrechula borregoensis Muma 1962

Ammotrechula borregoensis Muma, 1962: 41, figs 50-51; Muma, 1970a: 53; Muma, 1976: 27; Vázquez, 1981b: 80; Muma, 1989: 48; Brookhart and Brookhart, 2006: 324.
Ammotrechula dolabra Muma, 1963: 5, figs 18-19; Muma, 1970a: 53; Muma, 1976: 27 (synonymized by Muma, 1976: 27).

HOLOTYPE: Ammotrechula borregoensis: United States: California: San Diego County - Anza-Borrego State Park, April 28, 1955 (R. Schuster), 1 female (holotype).  Deposited in the American Museum of Natural History.   Ammotrechula dolabra: United States: Nevada: Nye County - Cane Springs, 12 miles NNW. of Mercury.

Original description:
Ammotrechula borregoensis Muma, 1962: 41, figs 50-51:
"FEMALE HOLOТYPE: Total length, 15.0 mm. Chelicerae 1.0 mm. wide and 3.1 mm. long. Propeltidium 2.4 mm. wide and 1.9 mm. long.  Color and markings in alcohol somewhat faded but apparently as follows: chelicerae light yellow; propeltidium раlе, dusky, purplish brown except for а narrow, light yellow, median stripe, а small oval light area оп each side of еуе tubercle, а large, longitudinal, light, diamond-shaped area, two irregular median light areas near the posterior margin, and а light yellow posterior marginal band; mesopeltidium, metapeltidium, and abdominal tergites light except for narrow lateral and posterior dusky margins; аll legs раlе yellow except for first pair which are раlе dusky purple оп tarsi, metatarsi, tibiae, and femora; palpi dusky purple оп tarsi, metatarsi, tibiae, and apical ends of femora; еуе tubercle dark, malleoli white. Dentition of chelicerae typical of the Ammotrechinae (fig. 50). Peak of dorsal carina occurring over first fondal tooth of ectal row. Palpi clothed with long and short hairs, scattered cylinder bristles оп tarsi, metatarsi, and tibiae, and two rows of 10 or more short, unpaired, cylindrical spines оп ventral surface of metatarsi and tibiae (fig. 51). Chelicerae three times as 10ng as wide. Propeltidium wider than long Ьу а ratio of 1 to 1.2. Eyes slightly less than опе diameter apart. Genital plate typical of family, wider than 10ng Ьу а ratio of 1 to 1.5."

Ammotrechula dolabra Muma, 1963: 5, figs 18-19:
Diagnosis: This species is distinguished by the robust untoothed fixed finger of the chelicerae and the lack of serially arranged spines on the tibia and metatarsus of the palpus.
"Males: Total length 10.5 to 11.0 mm.  Chelicerae 0.7 to 0.8 mm wide and 2.3 to 2.7 mm long.  Propeltidium 1.9 to 2.0 mm wide and 1.7 to
1.7 mm. long.  Holotype larger measurement.  Color light yellow with purplish-brown markings as follows: chelicerae with one dorsal and one ectal diffuse dusky stripe; propeltidium dark except for a narrow median stripe and the bases of the spines; mesopeltidium, metapeltidium and abdominal tergites pale on anterior third and dusky for the remainder of their length, palpi and  legs dusky except on coxae, trochanters, and distal portion of tarsi; venter pale; eye tubercle dark; malleoli white.  Dentition as shown in Figures 18 and 19.  Fixed finger and fond with only an indication of the normal teeth.  Dental group of movable finger occupies less than one-third of the length of the finger, principal tooth slightly larger than anterior tooth, Flagellum as on A. mulaiki Muma except the lower curled margin is fringed, attachment disc over area normally occupied by the first fondal tooth of the mesal row.  Palpi with usual clothing of long hairs, short hairs and cylinder bristles but no distinguishable series of spines on femora, tibiae or metatarsi.  Chelicerae slightly more than 3 times as long as wide,  Propeltidium wider than long by a ratio of 1 to 1.1.  Eyes separated by less than a diameter."

Muma 1970a:  DIAGNOSIS: Females are disgtinguished by having the palpus and leg I dusky, the other legs pale, and 2 rows of 10 or more unpaired short, strong, cylindrical spinelike setae on the palpal metatarsi and tibiae. Males are unknown.  DISCUSSION: Males of this distinctive species should be readily recognized by the coloration  of the legs and palpi.
