Figs 22A–B , 23A–B , 24

Type material. Holotype ♀: COLOMBIA: Meta Puerto Gaitan , ca. 20 km N Rio Muco, 20 km S El Porvenir [N4.02°, W73.76783°, 546 m] ( MCZ).

Etymology. The specific name is a patronym after the late Colombian arachnologist Andres Felipe García Rincón, a young scientist who did a lot for the field of arachnology, considering the short time he had.

Diagnosis. Females of F. andresi sp. nov. share with those of F. crassipalpis and F. brignolii sp. nov. the posterior vulvar plate extremely projected posteriorly, with a large portion visible in ventral view and rectangular in dorsal view ( Figs 22B , 23B ). They are easily distinguished by the inverted U-shaped median notch on the posterior margin of the epigynal plate ( Figs 22A , 23A ).

Description. Female (MCZ) Carapace reddish-brown, smooth. Chelicerae, endites, and labium reddish-brown. Sternum orangish-brown. Legs reddish-brown, with femora dark brown. Abdomen dark brown, elongated, with two pairs of white spots in middle, first pair three to four times larger than the second. Total length 5.798. Carapace 2.896 long, 2.248 wide. Clypeus height 0.216. Eye diameters AME 0.147, ALE 0.140, PME 0.119, PLE 0.101. Interocular distances AME-AME 0.097, AME-ALE 0.060, PME-PME 0.170, PME-PLE 0.138, ALE-PLE 0.059, PME-AME 0.104. Chelicera with three promarginal teeth, the second two times longer, and six retromarginal teeth, the most proximal to fang three times smaller than others. Sternum 1.389 long, 1.334 wide. Leg measurements I—2.392, 0.827, 2.384, 1.744, 1.477, 9.824; II—2.116, 0.779, 1.953, 1.745, 1.631, 8.224; III—Both missing; IV—1.963, 0.723, 1.467, 1.967, 1.115, 7.235.

Epigyne. Epigynal plate oval; copulatory opening positioned near posterior margin of epigynal plate; posterior margin of epigynal plate with inverted U-shaped median notch ( Figs 22A , 23A ); dorsally, vulva with well-developed posterior vulvar plate, trapezoid, with anterior margin extremely projected posteriorly, with large portion visible in ventral view; fertilization ducts short, secondary spermathecae posteriorly placed in relation to primary spermathecae ( Figs 22B , 23B ).
