Diagnosis. This species can be readily recognized from other Tityus (Archaeotityus) species by the following combination of character states: Total length: 28.16–39.11 mm (males) and 28.16–39.11 mm (females). General body coloration (Figure 21) dark yellow background moderately covered with dark brown variegated spots; metasomal segment V completely dark reddish-brown with three ventral black stripes and with a dorsomedian area without spots (Figure 6B, E). Metasomal segments II–III (Figures 15B, 16C, D) each has a distoterminal small acute granule on the DL carinae. Metasomal segment IV (Figures 15B, 16C, D) with a distoterminal medium-sized blunt, and coarse granule on the DL carinae. Metasomal segment V with the VSM2 macrosetae slightly distal or at the same level of the VL2 macrosetae (Figures 17B, 18B). Subaculear tubercle medium-sized pyramidal, flat, and triangle-like with an acute and coarse apex in lateral view (Figures 19B, 20B). Dorsal margin of the subaculear tubercle with a pair of ventrodistal small rounded granules with apices pointing to the middle portion of the aculeus. Vesicle and subaculear tubercle with VM carina composed of coarse granules and strongly crenulate in lateral view (Figures 19B, 20B). Telson with well-marked (female) (Figure 19B) or moderately marked (male) carinae (Figure 20B). Metasomal intercarinal areas densely covered with coarse granules (Figures 15B, 16C, D). Pectinal tooth counts and movable finger oblique rows of denticles: 11–15/ 11–13 (females) and 13–15/ 12–14 (males) (Table 2, 3). Metasomal segments II–V (Figures 15B, 16C, D), female pedipalp (Figure 11 D–F), and male pedipalp femur and patella (Figure 10C, D) short and of a medium-width. Chela (Figure 22 A–C) and metasomal segment V (Figure 16C, D) incrassate in large males.
Affinities with other Colombian species. Tityus columbianus is most similar to T. parvulus, sharing with it the presence of a subaculear tubercle that is medium-sized pyramidal, flat, and triangle-like with an acute and coarse apex in lateral view (Figures 19B, 20B). Tityus columbianus can be readily distinguished by the presence of a general body coloration with a dark yellow background moderately covered with dark brown spots (Figure 21); metasomal segment V completely dark reddish-brown with three ventral black stripes, a dorsomedian area without spots (Figure 6B, E) and with the VSM2 macrosetae; metasomal segments II–III each with a distoterminal small and acute granule on the DL carinae (Figure 15B, 16C, D) and metasomal segment IV with a medium-sized blunt, and coarse granule on the DL carinae (Figures 15B, 16C, D); metasomal intercarinal areas densely covered with coarse granules (Figures 15B, 16C, D); subaculear tubercle with VM carina composed of coarse granules and strongly crenulate in lateral view (Figures 19B, 20B); metasomal segments (Figures 15B, 16C, D) and male pedipalp femur and patella short and of a medium-width (Figure 10C, D).
Conversely, in T. parvulus the general body coloration is with a dark yellow background slightly covered with dark brown variegated spots (Figure 31); the metasomal segment V is dark yellow slightly covered with dark brown variegated spots and a pair of distal VL dark brown spots, but does not have dorsal spots neither the VSM macrosetae (Figure 33A, C); the metasomal segments II–IV do not have conspicuous distoterminal granules on the DL carinae (Figures 39A, 40A, B); the metasomal intercarinal areas are densely covered with fine granules (Figures 39A, 40A); the subaculear tubercle has a VM carina composed of fine granules and is feebly crenulate in lateral view (Figures 19D, 20D); the metasomal segments are slender in both sexes (Figures 39A, 40A, B) and the male pedipalp femur and patella are slightly elongated and slender (Figure 10G, H).
Remarks. Lourenço (2000) provided records for Tityus erikae from Vereda Miralindo, Medina, Cundinamarca department (ICN-As-194) and Santuario de Flora y Fauna Los Colorados, Bolívar department (ICN-As-188). These specimens were examined and we consider that they correspond to adult males of Tityus columbianus. Also, we examined two adult males, seven adult females and one juvenile female from Reserva Natural La Planada, Nariño department (ICN-As-712); and they also correspond to Tityus columbianus.
The records from Santuario de Flora y Fauna Los Colorados, Bolívar, and Reserva Natural La Planada, Nariño are unusually far away from the known distribution range of T. columbianus which is in the Eastern Cordillera in Cundinamarca and Boyacá departments. However, only new collections from these localities could explain whether these records are due to mislabeling errors or introduced populations.

Hemispermatophore capsule: the basal hook of the capsule exhibited different shapes in anterior view: (1) elongated with a thick and rounded apex, curved lateral margin, and forming ‘’U’’-shaped curve with the stem (Figure 23C) and (2) short with an acute apex, curved lateral margin, and forming a ‘’U’’-shaped curve with the stem (Figure 23D).
Male intrasexual variations: adult males exhibited different body sizes ranging between 28.16–39.11 mm, but despite this they did not show discrete size-classes, but rather a progressive increase in their total lengths (Figure 21 C–F, Table 9). However, as the total body size increases among males the following: (1) Carapace and tergites: the number of coarse granules on intercarinal surfaces increases; (2) Pedipalp femur: intercarinal areas have coarser and finest granules (Figure 9C); (3) Chela: the DI carina is more obsolete (Figure 22 A–F); the manus is more incrassate without apparently exhibiting isometric growth (n= 14; Cl/Cw= 3.1–4.7; Cl/Ch= 3.0–4.0) (Figure 22 A–F); (4) Metasomal segments II–IV: the DL carinae exhibit coarser distoterminal granules (Figure 16C, D); and (5) Metasomal segment V: segment is more incrassate without apparently exhibiting an isometric growth (n= 14; Msl-V/Msw-V= 1.8–2.1; Msl-V/Msh-V= 1.6–2.1) (Figure 16C, D), and the granules associated with carinae and intercarinal areas are less marked (Figure 16C, D).
