Type material. Holotype ♁ and paratype ♀ from La Bodega (13°56’40.7”N 87°13’23.9”W), Santa Ana , Francisco Morazán, Honduras, June 20, 2021, leg. A. Cubas (IBSP 324813) GoogleMaps . Paratype: one ♁ with same data as holotype (IBSP 324814).

Other material examined. HONDURAS: Francisco Morazán: Santa Ana, La Bodega (13°56’40.7”N 87°13’23.9”W), 1♁ (IBSP 324816); 1♁ 1♀ (IBPS 324815, SEM) GoogleMaps .

Etymology. The specific epithet is in honor of Dr. David Chamé-Vázquez (CIBNOR, México), for his great contributions to the study of the Mexican spider fauna and his great importance as a mentor in spider research for the first author.

Diagnosis. The males of Strotarchus chamevazquezi sp. nov. resemble those of S. minor Banks, 1909 by the presence of a basal embolar fold that crosses the apical portion of the tegulum, by the long embolus that arises retrolaterally, and by an extremely long cymbium (see Bonaldo et al. 2012: figs 103–104). They are differentiated by the absence of either ppRTA and laRTA (see Bonaldo et al. 2012: figs 103–104), by the arrow-shaped retrolateral tibial apophysis apices in ventral view (square in retrolateral view), and by the balloon-shaped embolar base ( Figs 1D View FIGURE 1 , 3A, 3B View FIGURE 3 , 4C View FIGURE 4 ). Females resemble those of S. minor by the elliptical atrium (see Bonaldo et al. 2012: fig. 105) but differ by the parallel copulatory ducts, converging abruptly toward the spermathecae, and by the lateral margin of anterior atrium superposed to the atrial posterior margin ( Figs 3C, 3D View FIGURE 3 ).

Description. Male (Holotype). Carapace light brown ( Fig. 1A View FIGURE 1 ), labium, endites and sternum lighter than carapace, head region and chelicerae reddish-brown, legs light yellow, opisthosoma cream, striated with narrow yellowish-brown bands. Total length 5.19. Carapace 2.5 long, 1.74, wide. Eye diameters: AME 0.22, ALE 0.16, PME 0.19, PLE 0.20. Chelicerae with 3 promarginal teeth, the median largest, and 2 retromarginal teeth, separated by twice their width ( Fig. 4A View FIGURE 4 ). Leg measurements: femur I 1.71/ II 1.22/ III 1.49/ IV 2.05. Leg spination: I—femur d1-1-1, p0-0-1, r0; tibia d0, p0, r0-0-1, v2-0-2; metatarsus d0, p1-1-1, r0-1-1, v2-2-2. II—femur d1-1-1, p0, r0-1-1; tibia d0-0-1, p0, r1-1-1, v1-2-0; metatarsus d0-1-0, p1-1-1, r1-1-1, v2-1-2. III—femur d1-1-1, p0-1-1, r1-1-1; tibia d0-0-1, p0-1-1, r0-1-1, v2-2-0; metatarsus d0-1-0, p1-1-1, r1-1-1, v2-2- 1m. IV—femur d1-0-1, p0-0-1, r0- 0-1; tibia d0, p0-1-1, r0-0-1, v2-2-2; metatarsus d0-1-1, p1-1-1, r0-1-1, v2-1-2. Palpal tibia ca. 1/3 of cymbium length, cymbium long, curved medially and ovoid-shaped in basal third; retrolateral tibial apophysis flattened and enlarged, apex sharp or blunt ( Fig. 4B View FIGURE 4 ); ppRTA and laRTA absent. Tegulum rounded, proximal fold of reservoir thick, Vshaped; tegular apophysis inserted ventrally on prolateral side of tegulum; embolar base visible retrolaterally as concave area on expanded palp ( Fig. 1D View FIGURE 1 ); basal embolar fold not clearly visible ( Figs 1C View FIGURE 1 , 3B View FIGURE 3 ), connecting with small portion of tegulum but displaced obliquely; embolar process small, rounded ( Figs 1B View FIGURE 1 , 3A View FIGURE 3 , 4D View FIGURE 4 ).

Female (Paratype, IBSP 324813). Coloration as in male, except with darker carapace ( Fig. 2A View FIGURE 2 ). Total length 6.52. Carapace 2.62 long, 2.0. Eye diameters: AME 0.25, ALE 0.16, PME 0.20, PLE 0.24. Chelicerae with promarginal teeth as in male and 2 retromarginal teeth, separated by three times their width ( Fig. 4E View FIGURE 4 ). Leg measurements: femur I 1.61/ II 1.57/ III 1.41/ IV 2.10. Leg spination: I—femur d1-0-1, p0-0-2, r0; tibia d0, p0-0-1, r0-0-1, v2-2- 0; metatarsus d0, p0-0-1, r0, v2-2-0. II—femur d1-1-1, p1-1-0, r0; tibia d0, p0-0-1, r0-0-1, v2-2-0; metatarsus d0, p0-0-1, r0-1-1, v2-2-1. III—femur d1-1-1, p1-1-1, r0-0-1, v0; tibia d0-0-1, p1-1-0, r1-1-0, v1p-2-0; metatarsus d0, p1-1-1, r1-1-1, v2-2- 0. IV—femur d1-1-1, p0-0-1, r0-0-1; tibia d0-0-1, p0-1-1, r0-1-1, v2-0-2; metatarsus d0-2-2, p1-1-1, r1-1-1, v2-2-2. Epigynum with wide, narrow atrium with laterally projecting edges ( Fig. 2B View FIGURE 2 ); atrial pocket large, oval posteriorly, median slit without lateral notches, rounded anteriorly ( Figs 2D View FIGURE 2 , 3D View FIGURE 3 ). Copulatory ducts with helicoid folds; glandular knob small, nearly triangular, projected distally; spermathecae enlarged posteriorly, curved boot-shaped; spermathecae continuous with spermathecae stalk ( Figs 2 View FIGURE 2 C-D, 3E-F, 4F)

Variation. Three males: Total length 5.19 − 5.60, carapace 2.50 − 2.70, femur I 1.71 − 1.85.

Natural history. The specimens were captured manually in wild areas and inside houses in La Bodega. Distribution. Known only from the type locality, Santa Ana , Francisco Morazán, Honduras ( Fig. 5 View FIGURE 5 ) .
