1. Lyssomanes unicolor ( Taczanowski 1871)

Jelskia unicolor Taczanowski 1871, 1878 ; Lyssomanes unicolor Peckham, Peckham & Wheeler 1889 ; Galiano 1962, 1980; Logunov 2002.

Material examined. 2♂ [ Figures 2-4 ], Colombia, Córdoba, San Antero: Caño Mocho [N9.4143°, W75.8017°], [2m] 22 Apr 2018, estuary, mangrove forest, Rhizophora mangle L . tree, shaking foliage, E. Bedoya – Roqueme coll . ( LEUC; OARA –120). Type material deposited in the MCZ, AMNH not examined .

Diagnosis. According to Galiano (1962, 1980) the male of L. unicolor is easily distinguished by two dark bands on the opisthosoma ( Figure 2 ), by the shape of the RTA, with a truncated apex and the quadrangular shape of the retrolateral upper border ( Figures 3-4 ; see Galiano 1962, figs. 1-3). The tarsus bears a tubercle in a lower, retrolateral position. The embolus is short, thick and black in color, located in the prolateral part of the bulb; it appears somewhat flattened and rolled ( Figure 3 ), twisted on its axis in a helical shape, which is more evident at the apex on the retrolateral part of the bulb, with a highly developed median process ( Figure 4 ). The embolus is long, conical, with a sharp apex and black in color. The fan-shaped conductor protects the apex of the embolus ( Figures 3-4 ). The specimens from the Department of Córdoba, Colombia, agree with the descriptions of Chickering (1946) and Galiano (1962), and show no marked differences in the dentition of the chelicerae.

Measurements (mm; specimens from Colombia). Two males: TL= 4.97-5.11; CL= 1.84-1.86; CW= 1.63- 1.65; AL= 3.18-3.21. Width of eye rows, first: 1.03-1.05; second: 0.98-1.02; third: 0.57-0.59; fourth: 0.65- 0.69; eyes of the second row separated by 0.11-0.13, eyes in the third row separated from the eyes in the fourth row by 0.28-0.31. Diameter AME: 0.48-0.51; ALE: 0.25-0.27; PME: 0.09-0.10; PLE: 0.24-0.26.

Distribution. Lyssomanes unicolor is known from Brazil, Colombia, Ecuador, French Guiana, Guyana, Mexico, Panama, Peru, Suriname, Tobago, Trinidad, and Venezuela.
