Psalmopoeus ecclesiasticus Pocock, 1903: 82, 84; Petrunkevitch 1911: 86; 1939: 289; Roewer 1942: 256; Schmidt, Bullmer & Thierer-Lutz 2006: 8, fig. 10; World Spider Catalog 2021.
Diagnosis. Males can be distinguished from those of all other species by slender embolus very curved distally, 5 or more times tegulum length in retrolateral view (Fig. 217). Females resemble those of P. cambridgei, P. irminia and P. pulcher by the elongated, non triangular spermathecae (Fig. 224). They differ by having the spermathecae apex curved toward center, and central area with 3–4 oval lobes weakly sclerotized (Fig. 224). Additionally, males and females have the stridulatory organ with curved line of thick setae (Figs 225, 227).
