| Distribution | Mexico (México, Morelos) Type locality: approx. 4 km E Ocuilan (approx. 15 km W Cuernavaca City limits) on dirt road Curenavaca-Chalma, near Rancheria Tlaltizapán, Municipality of Ocuilan, state of Mexico, Mexico (99° 23’ 25” N, 18° 57’ 16” W, 2350 m elevation). |
| Reproduction | ovoviviparous |
| Types | Holotype: MZFC 9580, adult male; paratypes (23): MZFC, EBUM |
| Diagnosis | Diagnosis (n = 23-24): Barisia herrerae may be distinguished from all other species and subspecies of the genus (Table 3) by having two anterior gulars between the second chinshields (one anterior gular in -92% of the specimens in the other taxa) and usually (in 78.3% of the specimens) five scales in the first temporal row, three of them between the levels of the dorsal and ventral margins of the orbit (four scales in the first temporal row, two of them between the levels of the dorsal and ventral margins of orbit, in -95% of the specimens in the other taxa). Barisia herrerae also differs from all the other taxa in the genus, except B. rudicollis, in having the rostral in contact with the nasal (in 96% of the specimens); cantholoreal series divided vertically (two loreal scales, the anterior one smaller than the posterior); usually (in 89.6% of the specimens) four superciliaries; three occipitals; 4-6 nuchals, the lateral ones strongly keeled, projecting laterally; 29-33 (x = 31) transverse dorsal scale rows; and 14 longitudinal ventral scale rows. In the other taxa, the rostral is always separated from the nasal; the cantholoreal series is not divided (one loreal scale) or is divided horizontally (one canthal and one loreal scale); there are usually three or less superciliaries (four superciliaries in '9% of the specimens); one occipital (-95%); and 8-10 nuchals, the lateral ones only weakly keeled, not projecting laterally; and there are 34 or more transverse dorsal scale rows and 12 longitudinal ventral scale rows. In addition to the above characters, B. herrerae may be distinguished from B. rudicollis in having no dark marks on the subocular region, immaculate ventral surface and olive-green dorsum in adults, and each scale on the dorsal surface finely stippled with white in adult males. In B. rudicollis, there is a dark, vertical stripe on the posterior subocular and adjacent supralabial; dark, short irregular spots on the gular region and sides of chest and abdomen (more abundant in largest males); a pale to dark brown to brownish gray dorsum; and much larger, irregular white marks restricted to the dorsal and lateral surfaces of the head and limbs and posterior margins of the dark transverse bands in adult males.
