Type-species by monotypy. Male lectotype designated from Colonia 
Tovar, Venezuela (probably in Aragua State) ; in Museum national 
dTlistoire naturelle, Paris, examined. 
Although Simon described the genus Psellocoptus as new in his 
Histoire naturelle des Araignees (1897), the species bearing the 
generic name had been described a year earlier and so both genus 
and species name should be dated “1896.” 
Generic Characteristics: Moderately large castianeirine ground 
running spider (7.5 to 11.5 mm. in length). Carapace dark with a 
wide, domed cephalic region tapering to a flatter thoracic region 
having moderate depressions and lateral indentations between coxae II 
and III and coxae III and IV, ending in a short petiole (Fig. 4). 
A small but distinct thoracic groove. Carapace with a distinct and 
complex pattern of white plumose hairs (Figs. 4 and 8) and some long 
thin simple setae on the cephalic region. Eyes arranged in two rows, 
the posterior row about one and one-half times as wide as the ante- 
rior row, the anterior row straight, the posterior row slightly re- 
curved; the posterior eyes equal, the anterior medians slightly larger 
than the posterior eyes, the anterior laterals much smaller (Figs. 2 
and 3). 
Abdomen elongate ovoid, generally brown dorsum with some lighter 
pigmentation markings and an anterior dorsal sclerite. Whole dor- 
sum slightly shiny as if weakly sclerotized. A pattern consisting of
