Material examined. 1♂ [ Figure 6 ], Colombia, Co ́ rdoba, San Antero: CanBo Mocho [9°24'53.3"N, 75°48'07.8"W], [2m] 23 Apr 2018, estuary, mangrove forest, Rhizophora mangle L . tree, shaking foliage, E. Bedoya – Roqueme coll . (LEUC; OARA-087). Type material deposited in the NMB, MIZ, MZUF not examined .

Diagnosis. According to Edwards (2015) males of P. dybowskii ( Figure 6A ) can be easily identified by the presence of a distinctive femoral organ on the distal prolateral femur of the pedipalp ( Figure 6B ), and a variably developed but mostly membranous, lobe-like to sclerotized spike-like lateral subterminal apophysis near the embolus, usually containing spicules ( Figure 6C ).

Measurements (specimens from Colombia). One male: TL= 5.27; CL= 2.24; CW= 2.78; AL= 2.85; AERW= 2.20; PERW= 2.23; LOQ= 2.24; PMEP=0.26; eyes of the second row separated from the ALE by 0.31 mm and from the PLE by 0.34 mm.

Natural history. According to Edwards (2015), specimens of P. dybowskii are frequently found in altered low vegetation, secondary growth, and along the forest margin. Some species of the genus are genus and may be generalized ant imitators. Here we report this species in association with the Rhizophora mangle L. tree in mangrove forests in the estuarine zone.

Distribution. Brazil, Colombia, Ecuador, French Guiana, Grenada, Guatemala, Guyana, Mexico, Panama, Trinidad, Venezuela.
