Nopsides ceralbonus Chamberlin

Figures 1–84

Nopsides ceralbona Chamberlin, 1924: 602 , figs. 38–41 (juvenile holotype from Isla Cerralvo, Baja California Sur, Mexico, in CAS; examined, and determined to be juvenile, by R. Schick; juvenile paratypes from the same locality, in MCZ; examined).

Nopsides ceralbonus: Bonnet, 1958: 3115 (emendation, to match the gender of the generic name).

DIAGNOSIS: With the characters of the genus, male palps with a large, rounded bulb and a ventrally situated embolus with a curved tip (figs. 3, 5, 6, 8, 9), and female genitalia sclerotized only along the anterior margin of the receptaculum (figs. 83, 84).

MALE (figs. 1–49): Total length 7.1–8.9 (n = 10). Carapace 3.0–3.5 long, 2.0–2.7 wide. Femur I 1.7–2.8 long, 0.7–0.9 wide. Bulb large, relative to size of cymbium; embolus long, narrow, membranous prolaterally near apex; in ventral view broad throughout length.

FEMALE (figs. 50–84): Total length 7.1–9.5 (n = 10). Carapace 2.8–3.2 long, 2.2–3.0 wide. Femur I 0.9–2.3 long, 0.6–0.8 wide. Internal genitalia with sclerotized anterior margin, sclerotization strongest near midline.

DISTRIBUTION: Northern and central Mexico.

NATURAL HISTORY: During the day, these spiders hide under large stones in xeric shrubland; they apparently become active at night, as most specimens have been taken in pitfall traps. Adult males have been taken from April through November, females from March through November.
