Arango, Stephania Sandoval, Obando, Ranulfo González & Aldrete, Alfonso Neri García, 2016, New species of Graphocaecilius Enderlein (Psocodea: ‘ Psocoptera’: Lachesillidae) from Colombia, Zootaxa 4147 (4), pp. 421-432 : 422

Key to the species of Graphocaecilius

(Modified from Mockford & Sullivan (1986). G. enderleini Williner, (1949) , not included; the original description of this species is focused in body coloration and wing shape, not allowing for the comparisons of genital structures. It is a Bolivian species, that has not been recorded in other countries (GBIF secretariat 2013), suggesting it may be different from the ones here listed).
