RESUMO
Lachesilla is the most species-rich psocid genus, with 341 species grouped into 19 species groups (with at least 100 undescribed species), plus an additional undescribed species group. We present the first phylogenetic analysis of Lachesilla and a discussion on the relationships of sister genera of the subfamily Lachesillinae. We codified a matrix of 60 morphological characters (16 multistate and 44 binary) formed by 44 terminals: 37 ingroup species and seven outgroup species. A phylogenetic analysis was performed using Maximum Parsimony (MP) as optimality criterion, under equal weights and implied weights approaches. Monophyly of Lachesilla is not recovered, showing a polyphyletic genus divided in two major clades: clade A, composed of the pedicularia species group + Nadleria, and clade B, including the remaining species groups. The implied weights analysis produced a hypothesis with Hemicaecilius as sister group of clade B, nesting seven subclades mainly with low branch support values (symmetric resampling and bootstrap). These results suggest that all species groups, included in this analysis, can be considered monophyletic clades based on several synapomorphies, despite the andra species group was split up showing that L. punctata + L. dentata cluster together with high branch support values, but L. tehuautlensis and L. falcicula were recovered in different subclades.

Two species of Waoraniella from Valle del Cauca, represented by both sexes, are here described and illustrated. The new species were found in the Andean region, between 1000-2000 m above sea level, constituting the first record of the genus outside the Amazon Basin. An identification key and a distribution map of the known Waoraniella species is included.

Two species of Lachesilla, in the pedicularia species group, from the Colombian Amazonia, are here described and illustrated. Also, a record of L. asymmetriproctus García Aldrete, for the Colombian Department of Putumayo is provided. An identification key to Lachesilla species in the pedicularia group with a single male clunial apophysis is presented, together with a diagnosis of this assemblage of species. A table is included indicating the distribution of Lachesilla species with one and two male clunial apophyses. The species treated in this paper constitute the first lachesillids known from the Department of Putumayo, Colombia.

Acantholachesilla saltoensis gen. et sp. n. is described from Valle del Cauca, Colombia, in the Lachesillidae, tribe Graphocaeciliini (Eolachesillinae). The genus is related to Dagualachesilla and Dagualachesilloides that occur in the same area, differing from them in the male clunial projection, phallosome, and female subgenital plate and gonapophyses.

The results of a survey of the psocid family Ectopsocidae in Valle del Cauca and NNP Gorgona, are here presented. Fifteen species were identified, in the genera Ectopsocus (14 species), and Ectopsocopsis (one species); four of the Ectopsocus species are new to science and are here described and illustrated. The male of E. thorntoni García Aldrete is here described. Records of Ectopsocopsis cryptomeriae (Enderlein), Ectopsocus briggsi McLachlan, E. californicus Banks, E. columbianus Badonnel, E. maindroni Badonnel, E. meridionalis Ribaga, E. pilosus Badonnel, E. richardsi Pearman, E. titschacki Jentsch, and E. vilhenai Badonnel, are provided. Ten species were found only in Valle del Cauca, two species were found only in the NNP Gorgona, and three species were found at both sites. The specimens studied are deposited in the Entomological Museum, Universidad del Valle, Santiago de Cali, Colombia (MUSENUV).
