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. 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. FIGURE 19. Diplocentrus sissomi , n. sp. , habitus, dorsal ( A, C ) and ventral ( B, D ) aspect. A, B. Paratype ♂ (AMNH). C, D. Paratype ♀ (AMNH). Scale bars = 10 mm. 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 ).
