Yucatan - Chichen Itza, at lights, 24 June 1951 (L. J. Stannard), 2
males (holotype, allotype). Deposited in the American Museum of
Muma, 1986: 16, figs 41-42:
HOLOTYPE: Total length, 12.5 to 16.5 mm. Chelicerae, 0.9
to 1.3 mm. wide and 3.2 to 4.2 mm.
long. Propeltidium, 2.2 to 3.0 mm. wide and 2.1 to 2.6 mm. long.
Holotype larger measurements. Chelicerae,
0.7 mm. wide and 2.6 mm. long.
Coloration in alcohol
pale to dusty yellow with purplish brown markings as follows:
venter, sternites, malleoli, and appendage coxae pale yellow; chelicrae
and propeltidium dusty yellow; palpi dark on tarsi and apical half of
metatarsi with other segments dusty yellow; leg 1 dusky on tarsus,
metatarsus, and tibia with other segments pale yellow; leg 2
indistinctly dusky on femur, tibia, and metatarsus with other segments
pale yellow; leg 4 dusky on femur, tibia, and metatarsus with other
segments pale yellow.
Structure similar to that of
other males of the genus. Dentition as shown in figure 41.
Palpi with 5 pairs of spine-like setae, as shown in figure 42.
Chelicerae 3.4 times longer than wide. Propeltidium 1.1 times
wider than long. Eyes separated by slightly less
than one diameter.
Flagellum attached to fixed finge behind principal tooth."

male palpus, tibia, metatarsus, and tarsus, mesoventral view.
(Yucatan). Known only from
PUBLISHED RECORDS: Known only
from the type series.
NOTES: Muma (1986,1987)
stated that this species appears to be closely related to A. stolli
[sic], but can be distinguished by its pale palpi, which are dark only on
the tarsi and apical ends of the metatarsi, and the obscure indentation on
the dorsal margin of the fixed cheliceral finger. He further noted
that it differs from A. nigrescens Roewer 1934 and A. chiapasi
Muma 1986 in having much paler and less extensive markings, and differs from
A. limbata (Lucas 1835) in possessing 5, rather than 4, pairs of
spine-like setae on the palpal metarsus.
Vázquez Rojas (1995) included the
species in a checklist of arachnids occurring in Mexico. Armas (2004)
listed the species in a catalog of the solifuges of Central America and the
Antilles, noting that it was known only from two males taken at a light at
the type locality. Brookhart and Brookhart (2006) included the species in their
checklist of North American solifugae, again noting that it was known
only from the
holotype and paratype mentioned above.
