Guyalna flavibasalis ( Distant, 1905) n. comb.

Fidicina flavibasalis Distant 1905d: 317 . (Ecuador)

Remarks. I found a similar problem with the generic assignment of Fidicinoides flavibasalis while trying to identify specimens for this study. The species was transferred to Fidicinoides based on the small lateral metascutellar pltes, te small dorso-lateral opening to the timbal cavity, the smooth lateral surfaces of the cruciform elevation, and the eyes not exceeding the breadth of the suprahumeral lobes of the pronotum ( Sanborn et al. 2008). However, this species also possesses tripartite tarsi meaning it should be classified in the Guyalnina and not the Fidicinini . Therefore, based on the tripartite tarsi, the head being wider than the mesonotum with eyes protruding beyond the anterior pronotum, the pronotum shorter than the mesonotum, partially visible metanotum laterally by the wing groove, a arched posterior cruciform elevation, triangular opercula not meeting along midline, a timbal cover that conceals only the lateral portion of the timbal with a concave anteromedial margin and semicircular anterior apex, the ventral timbal cover margin parallel to the long body axis, a rounded pygofer distal shoulder, the lack of a dorsal beak, large upper pygofer lobes separated from pygofer, indistinct basal pygofer lobes, horseshoeshaped uncus when viewed from the posterior and a tubular aedeagus, the species should be calssified in the genus Guyalna based on the current characteristics of the genus ( Sanborn 2016a). The species is reassigned to Guyalna to become Guyalna flavibasalis ( Distant, 1905) n. comb.

Distribution. The species has been recorded from Colombia and Ecuador ( Metcalf 1963a; Sanborn 2013).
