ETYMOLOGY: The Mexican slang terms chingón (masculine) and chingona (feminine) have a variety of meanings, including to denote something of high quality, and is here applied as an adjective.

DIAGNOSIS: The male is unknown. Females can be distinguished from other species lacking sclerotized bars by the unsclerotized spermathecae with glandular pores grouped into several small patches (instead of a single, large patch) (fig. 78).

DESCRIPTION: Female holotype from 6 miles S of Arteaga, Michoacán Mexico (CAS 9057614). Coloration brown. Carapace light orange-brown, densely stippled with brown. Labium endites and sternum light orange. Ster- num not particularly hirsute. Legs brown, with yellowish-brown longitudinal stripes on coxae, femora, and tibiae; femora and tibia I and II hirsute, with long setae. Abdomen dorsum brown. Anterior margin of the carapace unmodified. Sternum oval, with two pairs of sigillae. Total length 12.77. Carapace length 5.31, width 3.94, clypeus length 0.73. Eye diameters and interdistances: AME 0.295; PME 0.32; ALE 0.293; PLE 0.328; AME–AME 0.07; PME– PME‰.391. Sternum length 2.4, width 2.23.

Palp: femur length 2.97, height 1.08; tibia length 1.8, height 0.88. Leg I: femur (fe) 5.84; patella (pa) 2.05; tibia (ti) 5.32; metatarsus (mt) 4.71; tarsus (ta) 2.6. II: fe 4.68; pa 1.72; ti 4.01; mt 3.67; ta 2.03. III: fe 3.76; pa 1.52; ti 3; mt 3.19; ta 1.77. IV: fe 5.05; pa 1.65; ti 4.23; mt 3.93; ta 2.12. Abdomen: length 7.84, width 5.54. Palp macrosetae on ventral surface of tibia and tarsus. Leg macrosetae present on ventral surfaces of tibiae, metatarsi, and tarsi; all femora and metatarsi III with 2–4 dorsal macrosetae. Calamistrum with three rows with 9–12 setae each. Interpulmonary fold large, rounded, covering the spermathecae dorsally. Sclerotized lateral bars absent; spermathecae unsclerotized, with sparse patches of glandular pores in its base and an unsclerotized rounded apex lacking glands. State of the specimen: good, genitalia dissected, right leg IV disarticulated from tibia, left leg III missing from tibia.

Male unknown.

INTRASPECIFIC VARIATION: Females (N = 2): total length 8.41–12.77 (10.59), carapace length 3.63–5.31 (4.47), femur I length 4.16–5.84 (5), tibia I length 3.75–5.32 (4.54), femur/carapace ratio 1.1–1.15 (1.13). The genitalia do not vary noticeably (fig. 78).

NATURAL HISTORY: Unkown; the few specimens in collections do not have natural history data associated with them.

DISTRIBUTION: Western Mexico, in Guerrero and Michoacán states. The record from Nayarit is based on a subadult female and thus should be taken with caution (fig. 4C).

ADDITIONAL MATERIAL EXAMINED: MEXICO. Nayarit: 5 miles NE San Blas (N21.34°, W105.12°), W.J. Gertsch and W. Ivie, 14.v.1963, subadult♀ (AMNH IFM-1636).
