Material examined. 1♂, 2♀ [ Figures 20-26 View Figures 20-26 ], Colombia, Córdoba, San Antero: Caño Mocho [9°24'38.6" N 75°47'31.3" W], [2m] 23 Apr 2017, mangrove forest, Rhizophora mangle L . tree, shaking foliage, E. Bedoya – Roqueme coll . ( LEUC; OARA –144). Type material deposited in the AMNH, BMNH, MCZ not examined .

Diagnosis. According to F. O. Pickard-Cambridge (1901), Chickering (1946) and Maddison (1996), the females of Gastromicans levispina can be identified by their small epigynal plate, about as long wide, with a fairly deep posterior notch ( Figure 22 View Figures 20-26 ). The anterior half of the epigyne is occupied by two elongated depressions separated by a low septum about as wide as each depression ( Figures 22-23 View Figures 20-26 ; see Chickering 1946, fig. 224; Maddison 1996, figs. 93-95). The males can be identified by an embolus that originates on the prolateral side of bulb ( Figure 24 View Figures 20-26 ), completes more than 3/4 of a circle and terminates in a slender filament which lies transversely across the cymbium ( Figures 25-26 View Figures 20-26 ; see Chickering 1946, figs. 222-223).

Comparative description of specimens. Carapace long, wide at level of PLE, the dorsal surface, especially the interocular area, finely granulate, rather robust in general with lateral sides well rounded from ALE to prolateral corners, and a very short, broad, median longitudinal, thoracic groove in a shallow depression extending half way from the posterior eye row to the beginning of steep posterior declivity, which in turn extends about half way to the posterior margin of the carapace ( Chickering 1946; Maddison 1996). The male and female specimens from Colombia described here have cheliceral teeth as described by F. O. Pickard-Cambridge (1901), Chickering (1946) and Maddison (1996). Abdomen ovoid, longer than wide. Femur of male pedipalp strongly curved ventrally ( Figure 25 View Figures 20-26 ), covered dorsally with white lanceolate hair. Patella and tibia of male pedipalp both short, RTA a simple, robust spur directed forward ( Figure 26 View Figures 20-26 ), tarsal bulb constricted posteriorly, embolus originating on prolateral side of bulb ( Figure 24 View Figures 20-26 ), completing more than three fourths of a circle and terminating in a slender filament which lies transversely across cymbium ( Figure 24 View Figures 20-26 ; see Maddison 1996, fig. 93). The epigyne of the female is small, about as long as wide ( Figure 22 View Figures 20-26 ; see Maddison 1996, figs. 94-95), with a fairly deep posterior notch ( Figure 22 View Figures 20-26 ; see Maddison 1996, figs. 94-95), an anterior half occupied by two elongated depressions separated by a low septum about as wide as each depression ( Figures 22-23 View Figures 20-26 ; see Maddison 1996, figs. 94-95).

Spines (specimen from Colombia): Male: Leg I: F= d 0-0-1-1-1, p 2; P= p 0-2-0, r 0-1-0; T = p 0-0-1-0, r 0- 1-0, v 2-2-2; M= v 0-2-2 (same as in Chickering 1946, Leg right: v 1-2-2). Leg II: F= d 0-0-1-1-1, p 2, r 0-0- 1; P= p 0-1-0, r 0-1-0; T = p 0-1-1-0, r 0-1-1-0, v 1r-1-2; M= p 1-1, r 1-1, v2-2. Leg III: F= d 0-0-1-1-1, p 2, r 0-0-1; P= p 0-1-0, r 0-1-0; T = p 0-1-1-0, r 0-1-1-0, v 0-0-2; M=p1-2, r 1-2, v0-2. Leg IV: F= d0-1-1-1, p 1, r 1; P= 0; P= p 0-1-0, r 0-1-0; T = p 1-0-1, r 0-1-1-0, v 0-2; M= p1-2, v0-2. Two females: Leg I: F= d 0-0-1-1- 1, p 2; P= p 0-1-0; T = v 2-2-2; M= v 2-2. Leg II: F= d 0-0-1-1-1, p 2, r 0-0-1; P= p 0-1-0, r 0-1-0; T = p 0-1, v 1r-1r-2; M= p 1-0-1, v2-2. Leg III: F= d 0-0-1-1-1, p 2, r 0-0-1; P= p 0-1-0, r 0-1-0; T = p 0-1, r 1-1, v 0-0-2; M=p1-2, r 1-2, v0-2. Leg IV: F= d0-1-1-1, p 1d, r 1d; P= r0-1-0; T = r 0-1, v 0-0-2; M= p1-1, r0-1, v0-2.

Measurements (mm; specimens from Colombia). Male: TL= 5.14-5.2; CL= 2.28-2.31; CW= 2,06-2.1; AL= 2.67-2.7; AERW = 1.56-1.61; PERW = 1.69-1.72; LOQ= 1.57 9-1.59; PMEP = 0.29-0.3; eyes of the second row separated from the ALE by 0.31 mm and from the PLE by 0.46-0.48 mm. Two females: TL= 5.39-5.41; CL= 2.15-2.17; CW= 2.08-2.1; AL= 3.4-3.6; AERW = 1.5-1.7; PERW = 1.74-1.75; LOQ= 1.4-1.5; PMEP =0.30-0.31; eyes of the second row separated from the ALE by 0.27 mm and from the PLE by 0.52-0.55mm.

Distribution. Gastromicans levispina is known from Colombia (Deparment of Cordoba) and Panamá.
