description: <i>Sparianthina rufescens</i> (Mello-Leitão, 1940) comb. n. Figs 34-49 <i>Anaptomecus rufescens</i> Mello-Leitão, 1940: 180, fig. 8-9 (description &amp;female;; holotype &amp;female; [PJ 1662], Guyana, Essequibo River [6°21’53.25”N, 58°37’52.36”W], 1930.1164, No. 3491, A.W. Richards (c.), Oxford University Expedition K.B.G., NHM, examined). Roewer 1954: 712. Platnick 2009. <b>Notes.</b> Mello-Leitão (1940: 181) listed “type no. 2491”. Although the label shows “3941” it is considered the holotype female according to the match of other data. A juvenile (PJ 1663) apparently of the same species was in the same vial, as well as one male Salticidae. The juvenile is not considered to be a syntype, as Mello-Leitão wrote “type” in singular. <b>Further material examined.</b> GUYANA. 1 ♁ (PJ 1665), Guest, Maraballi River, Essequibo River, 15 miles above Bartica, Bottle I, No. 68, 1.II.[19]29, R.W.G.
