Etymology. The species name is a noun in apposition taken from the type locality.

Diagnosis. The male palpus of Cryptachaea pilar  new species differs from the other species of the genus by their very large, subquadrangular tegulum that ventrally covers all the embolus ( Figs. 1View FIGURES 1–4, 20, 22View FIGURES 20–25), and apex of the cymbium without projections ( Figs. 1, 2View FIGURES 1–4, 20–22View FIGURES 20–25). The female have two circular copulatory openings ( Figs. 3, 4View FIGURES 1–4, 25View FIGURES 20–25), as Cryptachaea cidae  Rodrigues & Poeta, 2015 (see Rodrigues & Poeta, 2015: fig. 1b), but differ from this species by the oval spermathecae ( Figs. 3, 4View FIGURES 1–4), more separated from each other and fertilization ducts inserted submedianally in the spermathecae ( Fig. 4View FIGURES 1–4), posteriorly in C. cidae  .

Embolus with two apical processes, one of them more robust ( Figs. 2View FIGURES 1–4, 21View FIGURES 20–25), the minor process serves as a hook, with prolateral coupling, in the concavity of the alveolus of the cymbium ( Fig. 2View FIGURES 1–4). Tegulum subquadrangular, large and robust ( Figs. 1View FIGURES 1–4, 20, 22View FIGURES 20–25). Cymbium oval ( Fig. 2View FIGURES 1–4), with tarsal organ circular and large ( Figs 21, 23View FIGURES 20–25), and with stridulatory ridges in the apex of cymbium ( Fig. 23View FIGURES 20–25).
