Type species. Psalmopoeus cambridgei Pocock, 1895 by monotypy.
Diagnosis. The species of Psalmopoeus can be distinguished from Ephebopus by lacking a urticating setae pad on the prolateral distal femur of palp. They differ from Tapinauchenius and Amazonius n. gen. by the presence of a maxillary lyra with one row of thick bristles in conjunction with a row of long filiform setae strikers on the base of the ventral chelicera, before the teeth row (Figs 156–157); presence of short coverage setae densely grouped and smooth setae on the retrolateral side of the trochanter palp and femur, and on the prolateral and retrolateral sides of the same articles of leg I (Figs 1–2, 8–13).
Distribution. Mexico, Belize, Guatemala, Honduras, Nicaragua, Costa Rica, Panamá, Colombia, Venezuela, Trinidad and Tobago, Guyana, Ecuador and Brazil.
Composition. Psalmopoeus cambridgei Pocock, 1895, Psalmopoeus ecclesiasticus Pocock, 1903, Psalmopoeus emeraldus Pocock, 1903, Psalmopoeus irminia Saager, 1994, Psalmopoeus langenbucheri Schmidt, Bullmer & Thierer-Lutz, 2006, Psalmopoeus plantaris Pocock, 1903, Psalmopoeus pulcher Petrunkevitch, 1925, Psalmopoeus reduncus (Karsch, 1880), Psalmopoeus victori Mendoza, 2014.
Redescription. Carapace longer than wide, cephalic region slightly raised. Cephalic and thoracic striae conspicuous. Fovea straight, deep. Chelicerae without rastellum. Retrolateral side of chelicerae with densely grouped short and ordered coverage setae (Fig. 4). Strikers:1–3 lines of 4–9 spaced, long filiform setae disposed on ventralbasal portion of chelicera before the teeth row (Fig. 157). Eye tubercle slightly raised or raised, wider than long. Clypeus absent. Anterior eye row straight. Labium wider than long, with ca. 87–195 cuspules concentrated on anterior third center. Maxillary lyra well-developed, formed by a line of thick setae (Fig. 156). Maxilla sub-rectangular, anterior lobe distinctly produced into conical process, inner angle bearing ca. 105–240 cuspules. Labiosternal groove shallow, flat, with two slightly separate sigilla. Sternum longer than wide, posterior angle acute, not separating coxae IV. Sigilla: three pairs, posterior oval, anterior small, all one diameter or less from margin, some pairs sometimes not evident. Leg formula: I=IV II III (most species), or I = II = IV III (P. cambridgei and P. irminia males). Laterally directed setae on metatarsi and tibiae in males. Clavate trichobothria on distal 2/3 of tarsi. Scopula of tarsi and metatarsi I–II very extended laterally giving them a spatulate appearance. Femora IV without retrolateral scopula. Stridulatory setae absent on coxae of legs. Short and ordered coverage setae densely grouped on the retrolateral side of the maxillae/coxae, trochanter and proximal part of femur of palp and prolateral side of the same articles of leg I (Figs 1–2). Legs with spines on ventral apical tibiae and metatarsi, without central spines. ITC absent; STC with small denticles. Posterior lateral spinnerets digitiform. Urticating setae lacking. Male tibiae I with tibial apophysis with two processes, retrolateral longer than prolateral, metatarsi I folds on retrolateral side of tibial apophysis. A protuberance behind retrolateral process.Tibiae II lacking apophysis. Globose bulb with small subtegulum; prominence on prolateral tegulum weakly developed (P. ecclesiasticus) or developed (other species). Embolus not flattened, lacking keels, long, ending in curved tip (P. reduncus and P. victori) or straight (other species). Embolus proximal portion straight in frontal view. Cymbium sub-triangular in retrolateral view, with almost equal lobes, without developed rounded process on retrolateral lobe. Spermathecae straight, completely separated, elongate with well defined projections or lobes on apical and middle area (except P. reduncus and P. victori). All species showing ontogenetic changes on abdominal pattern. Brownish juveniles lacking metallic green or blue sheen, with black tarsi contrasting with other lighter articles.
