Psammodesmus calius : Jeekel 1963 : 90 (combination); Martínez-Torres 2016 : 66 , Anex. 7 figs 26, 37C, 38C, 39C, 40C, 41C, 42C, 43C, 44C, 45C (description; distribution). Types: ♂ holotype from Colombia: Cali; H. Dybas leg., 30-VI-1947 . Deposited at the FMNH, cat. no. FMNH- INS-916 ( Sierwald et al . 2005 ; Martínez-Torres 2016 ). Distribution: Colombia , Dep. Valle del Cauca . Comments: In the original description the species names appears both as Platyrrhacus calius (P. 579) and Platyrhacus callius (p. 581). The second combination seems, as indicated by Jeekel (1963) , an obvious misprint, as could be the different spellings of the genus. Curiously, Chamberlin's handmade label for the holotype uses a different specific name, " orthogon ".
