Biology. The species is arboreal, and collected from trees in secondary forests or plantation areas.
Diagnosis. Blackish species; total length approximately 3.0 - 4.0 mm in males and 3.5 - 5.1 mm in females. Males distinguished from other species by structure of chelicera, which is anteriorly swollen and posteriorly narrow (Fig. 2); further distinguished from other species by first and second apical prolateral teeth of chelicera, which are long compared to other teeth (Fig. 5), and fang bearing short tooth-like apophysis submedially on its venter and weak protuberance on dorsum at its base (Fig. 6). Females distinguished from other species except Myrmarachne macrognatha (Thorell, 1894) by shape of dorsum of cephalic and thoracic parts, which are roundly convex (Fig. 11); Myrmarachne acutidens distinguished from Myrmarachne macrognatha by shape of proximal part of sclerotized copulatory ducts of epigyne, which is narrower in Myrmarachne acutidens (Figs 13 vs. 44).
Etymology. The specific name is derived from the second prolateral tooth counted from the apex in males.
