ABSTRACT

Quindina Roewer, 1914 is a nomoclastid genus with 11 described species behaviourally characterised by its remarkable nest-building behaviour. In this paper we describe two new Colombian species of the genus from the western range of the Northern Andes, based on genital morphology and external characters. In addition, we explore their phylogenetic relationships using a phenotypic matrix with 96 characters, three newly proposed, and 55 terminals including all described species of Quindina and a wide outgroup sample across the suborder Laniatores. Quindina sanantonio sp. n. (type locality: Valle del Cauca, Santiago de Cali, San Antonio Forest) can be diagnosed by having two olive-green patches behind the ocularium and on the lateral portion of areas II and III, connected on the posterior margin of area III. Quindina horologium sp. n. (type locality: Risaralda, Santuario, Planes de San Rafael) can be diagnosed by having an hourglass-shaped dorsal pattern, beginning as two emerald-green patches next to the ocularium and continuing to the posterior margin of area III. Both species build nests without walls on the underside of leaves (ie flattened nest type), a previously unknown nest architecture for the genus. The phylogenetic analysis confirmed the monophyly of Quindina. The two new species, herein described, were recovered as basally branching within the genus. The inferred ancestral state for the nest architecture was the flattened nest type. We provide an updated key for the Colombian species of the genus Quindina and an updated distribution map.
