Material examined. Holotype: 1♀ Brazil, Goias, Anapolis: Reserva Ecolo 6gica e Cientifica Trilha do Tatu [16°23'2.69"S, 48°56'39.36"W], [1075 m], October 15, 2019, dry forest, agitation of foliage, E. BedoyaRoqueme, R. F. Ribeiro col. ( LECA; A2 B2-3 , CE B1-3) . Paratypes: 2 ♀ Brazil, Goias, Anapolis : Reserva Ecolo 6gica e Cientifica Trilha do Tatu [16°23'2.79"S, 48°56'38.25"W], [1070m], October 29, 2019, dry forest, agitation of foliage, E . Bedoya-Roqueme, R . F. Ribeiro col . ( LECA; A2 B2-3 , CE B1-3). All types are deposited in the arachnological collection of the Laboratory of Behavioral Ecology of Arachnids ( LECA), at the State University of Goias, Ana 6polis, Goias, Brazil .

Etymology. The species group name florenciae (gen.) is given to honor the arachnologist Lic. MarÍ6a Florencia Nadal who first taught me how to identify specimens of the family Salticidae .

Diagnosis. Lyssomanes florenciae is similar to L. similis Logunov 2014 , but can be easily distinguished from that species by the arrangement of the insemination ducts and the shape of the receptacles.

Description of female, based on the female holotype (LECA; A2 B2-3, CE B1-3). Color in alcohol: body pale yellow ( Figures 1‒3 ), with scattered orange scales on ALE and PME, with few white hairs scattered throughout the carapace, becoming more visible near the PLE ( Figures 7‒8 ), light-yellow endites and labium with slightly sclerotized edges ( Figures 9‒10 ), pale yellow sternum, all legs uniformly light-yellow, metatarsus and tarsus a little darker, abdomen dorsum and sides with scattered dark hairs ( Figures 1‒3 ), especially in the anterior part, clear ventral area, especially the region of the book lungs, where it is whitish, light-orange sclerotized epigynum ( Figures 1‒3 ).

Cephalothorax wider than long ( Figure 4 ), the ALE, PME, and PLE on dark-colored tubercules ( Figure 4 ), surrounded by intense orange scales, and scattered white hairs ( Figure 7 ), the AME surrounded by orange scales ( Figure 8 ), with evident thoracic lines and a straight posterior margin ( Figure 9 ); sternum octagonal in shape ( Figure 10 ). Chelicerae are light-yellow and vertical, with two large teeth on the prolateral margin and a conspicuous small tooth on the medial prolateral margin ( Figures 11, 14 ), five teeth on the retrolateral margin, which decrease in size, and a small conspicuous sixth tooth near the medial retrolateral margin ( Figures 12‒13, 15‒16 ).

Abdomen elongated, with scattered dark hairs ( Figures 2‒3 ), abundant on the anterior margin, with some evident depressions ( Figures 5‒6 ). The epigynum is sclerotized, reddish-brown, oval, with a clear aperture, gonopores on both sides (Go, Figures 17, 19 ); connected directly to a fossa (Fo, Figures 17, 19 ), where the copulatory ducts begin. These ducts immediately curve, and then connect directly to the spermathecae (Sp, Figures 18, 20 ), culminating in the fertilization ducts ( Figures 18, 20 ).

Spination: Leg I: F= d 1*-2-2-2, r1-1-0; P= d 0-1r; T= d 0-0-2, v 2-2-2-2; M= v 2-2-2. Leg II: F= d 0-2-2, r1- 1-0; P= d 0-1; T= d 0-2, v 2-2-2; M= v 2-2-2. Leg III: F=d 0-2—2, r 1-1-1; P= d 0-1; T= d 0-1-1, r1-1, p1; M= v 0-2-2, d 0-0-1.

Measurements for three females: TL= 4.83–4.91; CL= 1.92-1.97; CW= 2.13–2.15; AL= 2.83–2.85; AERW= 1.14–1.16; PERW= 0.89–0.91; LOQ= 1.37–1.39; PMEP= 0.35–0.37; eyes of the second row separated from the ALE by 0.14–0.16 mm and from the PLE by 0.26–0.28 mm. Legs: F: I= 2.59‒2.60/0.46‒0.48, II= 2.35‒ 2.40/0.44‒0.46, III= 2.14‒2.16/0.41‒0.43, IV= 2.08‒2.12/0.30‒0.31; P: I= 0.89‒0.90/0.37‒0.39, II= 0.89‒ 0.90/0.32‒0.34, III= 0.78‒0.80/0.34‒0.36, IV= 0.66‒0.68/0.27‒0.29; Ti: I= 2.31-2.33, II= 2.08‒2.10, III= 2.23‒2.25, IV= 2.18‒2.20; M: I=2.25‒2.27, II= 2.11‒2.13, III= 2.28‒2.30, IV= 2.372.39; Ta: I= 0.63‒0.65, II= 0.63‒0.65, III= 0.65‒0.67, IV= 0.65‒0.67.
