DIAGNOSIS: The following character combination, updated from Francke (1977), is diagnostic for D. keyserlingii . Total length (adult), ca. 45 mm. Base coloration (adult) reddish brown to brown. Carapacial anteromedian notch moderately deep, V-shaped; frontal lobes and interocular surface moderately granular, other surfaces finely granular. Pedipalp femur, dorsal surface moderately granular. Pedipalp patella, dorsomedian carina strongly developed, crenulate to smooth (♂); dorsoexternal carina moderately developed, smooth to slightly crenulate (♂); externomedian carina weakly developed to obsolete, smooth (♂); ventromedian carina obsolete to weakly developed, slightly granular (♂, ♀). Pedipalp chela manus, dorsal surface markedly reticulate (♂; fig. 5A) or smooth (♀); digital carina strongly developed, smooth (♂) or obsolete, smooth (♀); dorsal secondary carina moderately developed, smooth to slightly crenulate; fingers gently curved (fig. 5A). Legs I–IV telotarsi, counts of spiniform macrosetae in pro- and retroventral rows, 4/5:5/5:5/5:5/6 (variation in table 1). Pectinal tooth count, 7–9, mode = 7 (♂) or 6–8, mode = 7 (♀) (variation in table 2).
Diplocentrus keyserlingii resembles D. kraepelini , n. sp., D. rectimanus , and D. sagittipalpus , n. sp., in adult size and coloration but can be distinguished as follows. The counts of spiniform macrosetae on the telotarsi of legs III and IV are lower in D. keyserlingii (5/5:5/6) than in D. kraepelini , n. sp. (6/6:6/6), D. rectimanus (6/6:6/6), and D. sagittipalpus , n. sp. (6/6:6/6). The pectinal tooth count (♂) is lower in D. keyserlingii (7–9) than in D. sagittipalpus , n. sp. (9–12). The pedipalp chela manus (♂) is rounded, the fingers shorter than the manus, in D. keyserlingii , but slender, the fingers longer than the manus, in D. rectimanus , and the manus, dorsal surface (♀) is smooth in D. keyserlingii but granular in D. rectimanus .
DISTRIBUTION: Diplocentrus keyserlingii is known only from the central valleys and adjacent mountains (part of the Sierra Norte) of Oaxaca in the following municipalities: Santa Catarina Ixtepeji, Santa Inés del Monte, Santa María Peñoles, and Santiago Tenango (fig. 3B).
ECOLOGY: This species was collected under logs and stones, and excavated from burrows constructed at an angle of ca. 20° to the ground surface, ca. 20 cm deep and fairly straight with some turns due to the presence of stones in the soil matrix. The dominant vegetation in the area was oak forest. Centruroides nigrovariatus ( Pocock, 1898) was collected in sympatry. The habitat and habitus of D. keyserlingii are consistent with the pelophilous ecomorphotype ( Prendini, 2001).

ETYMOLOGY: This species is dedicated to Karl Kraepelin for his contributions to scorpiology.
DIAGNOSIS: The following character combination is diagnostic for D. kraepelini , n. sp. Total length (adult), 50–55 mm. Base coloration (adult) brown to orange-brown. Carapace anteromedian notch moderately deep, U-shaped (fig. 7B). Pedipalp femur, dorsal surface finely and sparsely granular medially (fig. 9B). Pedipalp patella, dorsomedian carina moderately developed, crenulate (♂); dorsoexternal carina weakly developed to obsolete, smooth to slightly crenulate (♂); externomedian carina weakly developed, smooth (♂; fig. 11B); ventromedian carina moderately developed, smooth to slightly crenulate (♂, ♀). Pedipalp chela manus, dorsal surface markedly reticulate (♂; fig. 14A) or smooth (♀; fig. 14B); digital carina strongly developed, smooth to crenulate (♂) or weakly developed to obsolete, smooth (♀); dorsal secondary carina moderately to weakly developed, smooth (♂) or weakly developed to obsolete, smooth (♀); fingers markedly curved. Legs I–IV telotarsi, counts of spiniform macrosetae in pro- and retroventral rows, 4/5:5/5:6/6:6/6 (variation in table 2). Pectinal tooth count, 9–11, mode = 10 (♂) or 7–9, mode = 8 (♀) (variation in table 1).
Diplocentrus kraepelini , n. sp., D. keyserlingii and D. rectimanus possess similar counts of pectinal teeth and telotarsal spiniform macrosetae, but may be distinguished as follows. The pedipalp chela movable finger length is greater than the length of the carapace or metasomal segment V in D. kraepelini , n. sp., and D. rectimanus , but less than or subequal to the length of the carapace or metasomal segment V in D. keyserlingii . The counts of spiniform macrosetae on the telotarsi of legs I and II are lower (4/5) in D. kraepelini , n. sp., than in D. rectimanus (5/5), whereas the counts on the telotarsi of legs III and IV are higher (6/6:6/6) in D. kraepelini , n. sp., than in D. keyserlingii (5/5:5/6). The ventromedian carina is moderately developed, smooth to slightly crenulate in D. kraepelini , n. sp., but obsolete in D. rectimanus . The pedipalp chela fingers are markedly curved in D. kraepelini , n. sp., but straight to gently curved in D. rectimanus . The pedipalp chela manus, dorsal surface (♀) is smooth in D. kraepelini , n. sp., but granular in D. rectimanus .
Diplocentrus kraepelini , n. sp., resembles D. mitlae in size and coloration, but may be distinguished from the latter as follows. The pedipalp chela manus (♂), dorsal and external surfaces are reticulate and the digital carina strongly developed in D. kraepelini , n. sp., whereas the dorsal and external surfaces are smooth and the digital carina weakly developed in D. mitlae . The count of spiniform macrosetae on the telotarsi of legs I and II is higher in D. kraepelin i, n. sp. (6/6), than in D. mitlae (5/5).

ECOLOGY: This species was observed doorkeeping at burrow entrances at night with UV detection, and was excavated during the daytime. The burrows, constructed at an angle of ca. 30° to the ground surface, were ca. 30 cm long, and mostly straight with some turns around stones in the soil matrix. The dominant vegetation in the area was oak forest. An undetermined species of Centruroides Marx, 1890 , related to C. nigrovariatus , Vaejovis dzahui Santibáñez- López and Francke, 2010, and an undetermined species of Vaejovis were collected in sympatry. The habitat and habitus of D. kraepelini , n. sp., are consistent with the pelophilous ecomorphotype ( Prendini, 2001).
