Type material. Female holotype from Guatemala, 1930, Peckham coll., deposited in MNHN AR222 About MNHN ; female paratype from Sabanetas, near Barberena [14°17’38.3”N, 90°17’22.1”W], Santa Rosa Department, Guatemala, deposited in MCZ GoogleMaps .
Etymology. The species name is derived from the Maya word Alux and means “sprite” or “spirit” in the Mayan mythological tradition, generally associated with natural features such as forests.
Diagnosis. Females of Acanthoctenus alux ( Figs 35 View FIGURE 35 , 36D View FIGURE 36 , 37 View FIGURE 37 ) resemble those of A. virginea stat. res., comb. nov. ( Figs 32 View FIGURE 32 C–D, 33C–D) by the median sector subpentagonal, and the lateral sectors’ anterior border straight, forming a 60° angle with the median sector’s longitudinal axis. It can be distinguished by the atrium subtriangular, and the copulatory ducts relatively smaller. A. virginea stat. res., comb. nov. presents a suboval, slightly sclerotized atrium, and relatively longer copulatory ducts.
Description. Male. Unknown.
Female (holotype MNHN AR222). Total length 10.94. Carapace 4.26 long, 4.33 wide. Clypeus 0.20 high. Eye diameters: AME 0.28, ALE 0.18, PME 0.37, PLE 0.39 Leg measurements: I: missing; II: femur 5.06/ patella 2.41/ tibia 5.68/ metatarsus 3.78/ tarsus 1.36/ total 18.29; III: 4.10/ 1.80/4.12/ 3.40/ 1.51/ 14.93; IV: 5.78/ 2.12/ 5.74/ 7.41/ 2.23/ 23.28. Leg spination: I absent, tibia II v-2-2-2-2-2-2-2-2-2, p-1-1-0-1-1, r-1-0-1-1-1, III and IV v-2-2-2, p-1-1, r-1-1; metatarsus II v-2-2-2-2-2, p-1-1, r-1 III v-2-2-2, p-1-1-1, r 1-1-1, IV v-1-1-1-1-1, p-1-1-1, r-1-1-1. Epigynum ( Figs 35 View FIGURE 35 A–B, 36D, 37A–B): median sector subpentagonal, short, wide anteriorly extending into the atrium, projected posteriorly; anterior border of the lateral sectors straight; atrium subtriangular; copulatory ducts S-shaped, small; spermathecae head quote-shaped, with apical glandular openings, spermathecae base curled; fertilization ducts tubular, slanting outwards.
Variation. Two females: total body length 10.94–14.24, carapace length 4.26–6.18.
Distribution. Guatemala ( Fig. 10A View FIGURE 10 ).
