TYPE MATERIAL: MEXICO: OAXACA: DISTRITO DE TEHUANTEPEC: Municipio de San Miguel Tenango   : Holotype ♂ ( CNAN-T0273), 2 ♀ paratypes ( CNAN-T0274, 275), 2 juv. paratypes ( CNAN-T0276, 277), 2 ♀, 1 juv. paratypes ( AMNH), 1 ♀, 1 subad. ♀, 3 juv. ♀ paratypes ( AMCC [ LP 3693]), San Miguel Tenango   , 0.5 km W, 16°15.515′N 95°35.9533′W, 1571 m, 2. xi.2004, O. Francke, G. Villegas, and R. Paredes, UV light detection at night. GoogleMaps  

DIAGNOSIS: The following character combination, updated from Santibáñez-López and Francke (2008), is diagnostic for D. tenango   . Total length (adult), 40–50 mm. Base coloration (adult) dark brown to reddish brown. Carapace anteromedian notch moderately deep, V-shaped; margins weakly granular. Pedipalp femur, dorsal surface sparsely granular, especially medially.

Patella dorsomedian carina strongly developed, crenulate (♂); dorsoexternal carina moderately developed, smooth to crenulate (♂); externomedian carina weakly to moderately developed, smooth to crenulate (♂); ventromedian carina strongly developed, crenulate (♂) or weakly developed, smooth (♀). Pedipalp chela manus, dorsal surface reticulate (♂; fig. 6B) or weakly reticulate (♀); digital carina strongly developed, smooth (♂) or moderately developed, smooth to crenulate (♀). Legs I – IV telotarsi, counts of spiniform macrosetae in pro- and retroventral rows, 6/6:6/6:7/7:7/7 (variation in table 1). Pectinal tooth count, 12–13, mode = 13 (♂)   or 10–11, mode = 11 (♀) (variation in table 2).

Diplocentrus tenango   is most similar to D. keyserlingii   , D. rectimanus   , and D. sissomi   , n. sp., from which it may be distinguished as follows. The pedipalp patella ventromedian carina (♂, ♀) is strongly developed and crenulate in D. tenango   , obsolete in D. keyserlingii   and D. rectimanus   , and weakly developed and smooth to slightly granular in D. sissomi   sp. n. The pedipalp chela manus (♂) is rounded, with short, curved fingers in D. tenango   but slender, with long, straight fingers in D. rectimanus   . The counts of spiniform macrosetae on the telotarsi of legs III and IV are higher (7/7:7/7) in D. tenango   than in D. keyserlingii   (5/5:5/6), D. rectimanus   (6/6:6/6), and D. sissomi   , n. sp. (5/5:5/6). The pectinal tooth count is higher in D. tenango   (♂: 12–13; ♀: 10–11) than in D. keyserlingii   (♂: 7–9; ♀: 6–8) and D. sissomi   , n. sp. (♂: 8–10; ♀: 6–10).

DISTRIBUTION: Diplocentrus tenango   is known only from the type locality in the San Miguel Tenango   municipality of Oaxaca (fig. 3B).

ECOLOGY: This species was collected from burrows in road cuts along a logging track in pine forest. Centruroides hoffmanni Armas, 1996   , was collected in sympatry. The habitat and habitus of D. tenango   are consistent with the pelophilous ecomorphotype ( Prendini, 2001).
