Diplocentrus keyserlingii   group: Francke, 1977: 147, 148; 1978: 5, 23, 32, 33, 55; Sissom, 1994: 257–266.

DIAGNOSIS: Species of the keyserlingii   group may be distinguished from other species of Diplocentrus   by the following characters (fig. 1C–F). The length of the cheliceral movable finger is greater than the length of the manus and the length of the fixed finger is greater than the width of the manus in the keyserlingii   group, whereas the length of the movable finger is less than the length of the manus and the length of the fixed finger is less than the width of the manus in other species of Diplocentrus   . The height of the pedipalp femur is greater than its width and the dorsal surface of the femur is slightly to markedly convex in the keyserlingii   group, whereas the height of the femur is less than its width and the dorsal surface of the femur is flat or shallowly convex in other species of Diplocentrus   . The pedipalp chela ventrointernal carina is weakly to moderately developed, and not infuscated in the keyserlingii   group, but moderately to strongly developed and densely infuscated in other species of Diplocentrus   . The ventral surfaces of the basitarsi of legs III and IV each possess three terminal and one subterminal spiniform macrosetae in the keyserlingii   group (fig. 2C), but three terminal, one or two subterminal, and one medial spiniform macrosetae in other species of Diplocentrus   (fig. 2A, B).

INCLUDED SPECIES: Ten species are included in the keyserlingii   group as defined above: Diplocentrus coylei Fritts and Sissom, 1996   ; Diplocentrus formosus Armas and Martín-Frías, 2003   ; Diplocentrus hoffmanni Francke, 1977   ; Diplocentrus keyserlingii Karsch, 1880   ; Diplocentrus kraepelini   , n. sp.; Diplocentrus mitlae Francke, 1977   ; Diplocentrus rectimanus Pocock, 1898   ; Diplocentrus sagittipalpus   , n. sp.; Diplocentrus sissomi   , n. sp.; Diplocentrus tenango   Santibáñez- López and Francke, 2008.

DISTRIBUTION: Species of the keyserlingii   group are recorded from four states of central Mexico: Estado de México, Guerrero, Morelos, and Oaxaca (fig. 3)   .
