Etymology. The specific name is a noun in apposition in honor of the indigenous ethnic group, Apalai, who have remnants on the eastern side of Tumucumaque Mountains National Park, Almeirim, Pará, Brazil.

Diagnosis. Males of A. apalai are characterized by PA continuous to PI ( Fig. 15 View FIGURE 15 A–B); pronounced PA and BTA inconspicuous ( Fig. 15 View FIGURE 15 A–C); without serrated area, represented by the two cusps distal to PI ( Fig. 15 A, C View FIGURE 15 ). They differ from those of A. mairinquensis ( Fig. 18 View FIGURE 18 A–C) by BTA in the middle of the width of tegulum; PA more developed; serrated area reduced ( Fig. 15 A, C View FIGURE 15 ) and dorsal abdominal scutum divided in two parts, the basal larger and more rebordered than distal scutum ( Fig. 13 A View FIGURE 13 ). They differ from those of A. smuzikae by PA more pronounced and PS shorter ( Ríos-Tamayo & Goloboff, 2018, fig. 34 D–F).

MALE (holotype): Total length 14.55; Carapace, long 7.22; wide 6.66. Carapace anterior part slightly tapered. Anterior eye row slightly procurved, posterior row recurved ( Fig. 13 B View FIGURE 13 ). Few short bristles between posterior eyes, and between lateral eyes-edge of carapace; short bristles forming a row on edge of chilum. Sternum with eight sigilla fused medially, two distal sigilla more fused to each other than others ( Fig. 13 C View FIGURE 13 ). Rastellum protuberant, inverted V-shaped, hirsute, with 1–3 spines in prolateral part ( Fig. 13 View FIGURE 13 E–F). Chelicerae with denticles along prolateral row of teeth. Prolateral row decreasing in distal-proximal way. Teeth in retrolateral row subequal ( Fig. 13 D View FIGURE 13 ). Patella and tibia III with distal crown of welldeveloped thorns, not interrupted in middle ( Fig. 14 View FIGURE 14 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 14A, C View FIGURE 14 ). Patella IV with prolaterodorsal short spines along extension of article ( Fig. 14 D View FIGURE 14 ). Ventral pseudoscopulae occupying 75% of tarsi I and 100% of II, III and IV. Pseudoscopula compact only in 10% of distal part of tarsi I, 25% of II, and 100% of tarsi III and IV. Carapace and chelicerae reddish brown; sternum yellowish-brown; legs reddish-brown; tibia of palp and cymbium yellowishbrown; abdomen pale gray, with two dorsal scuta with points of insections of bristles more sclerotized than in rest of abdomen ( Fig. 13 A View FIGURE 13 ). Anterior scutum bigger and more rebordered than posterior.
