RESUMO
Lamprospilus stegmaier Prieto & Faynel sp. nov. is described from five specimens collected in sympatry with L. nicetus C. Felder & R. Felder on the northern central range of the Colombian Andes. Lamprospilus bicolor Faynel & Prieto sp. nov. is described from specimens collected in Colombia, Peru and Bolivia. Lamprospilus bicolor mirador Faynel & Prieto ssp. nov. is described from specimens collected in Peru and Bolivia. Lamprospilus decorata valluna Prieto & Faynel ssp. nov. is described from specimens collected in Western Colombia. Male and female phenotypes are associated, and we present morphological and molecular diagnostic characters for the new species. We also evaluate the congruence between a priori morphology-based species identifications and Molecular Operational Taxonomic Units (MOTUs) delimitations based on Barcode Index Numbers (BINs) in the genus. DNA barcodes are in perfect agreement with morphology in 64% of the species. Interspecific distances were found to range from 3.22% to 8.42% (average 5.48%), whilst their mean intraspecific variation ranges from 0.0% to 4.30% (average 1.78%). Based on DNA barcodes evidence of topotypic individuals, the study of original descriptions and illustrations of the holotypes, we consider here that Lamprospilus occidentalis Johnson & Salazar 2004 is a new junior subjective synonym of L. draudti Lathy, 1932.

The Catasticta poujadei group, within the subgenus Hesperochoia Reissinger, is revised. Two new species, C. copernicus Pyrcz & Fhraeus sp. nov., and C. buszkoi Boyer & Pyrcz sp. nov. occurring near the timberline in Junn and Apurmac are described. Catasticta eximia Rber is reinstated as a species separate from C. poujadei, and a new subspecies, C. eximia tapuna ssp. nov., is described. The affinities of the species of the C. poujadei group are evaluated based on COI barcodes. Their distribution and habitats are described.

The Transandean-Andean genus Johnsonita Salazar Constantino, 1995 is revised on the basis of wing and genitalia morphology. Apart from eight species formerly placed in Johnsonita (Thecla assula Draudt, 1919; Thecla auda Hewitson, 1867; Thecla catadupa Hewitson, 1869; Thecla chaluma Schaus, 1902, Thecla chlamydem Druce, 1907; Thecla pardoa d'Abrera, 1995; Johnsonita johnsoni Salazar Constantino, 1995 and Johnsonita johnbanksi Bálint, 2003), seven new species are described: Johnsonita carpia Bálint, Boyer Pyrcz, sp. n. (Ecuador), Johnsonita iacinta Bálint, Boyer Pyrcz, sp. n. (Peru), Johnsonita ianusca Bálint, Lorenc-Brudecka Pyrcz, sp. n. (Ecuador), Johnsonita oxalida Bálint, Boyer Pyrcz, sp. n. (Peru), Johnsonita subcunicula Bálint, Cerdeña Pyrcz, sp. n. (Peru), Johnsonita turquisca Bálint, Boyer Pyrcz, sp. n. (Ecuador) and Johnsonita zubkova Bálint, Boyer Lorenc-Brudecka, sp. n. (Peru). One species, erroneously recorded from Bolivia under the name Thecla chaluma Schaus, 1902, is not formally described due to insufficient material. An identification key, type material revision, descriptions or redescriptions, and diagnosis for all the taxa recognized are given. Lectotypes for the nominal species Thecla assula Draudt, 1919 and Thecla chlamydem Druce, 1907 are designated. Male secondary wing characters are tabulated. A brief discussion on classification, life-history and male secondary characters of Johnsonita is presented.

The validity of the monobasic neotropical butterfly genus Cheimas Thieme (Nymphalidae, Satyrinae, Satyrini, Pronophilina) is discussed, and confirmed based on morphological and molecular data. Cheimas opalinus (Staudinger), endemic to the Venezuelan Cordillera de Mérida, and considered prior to this study to be monotypic and restricted to the central part of the range, is demonstrated to be polytypic and more widely distributed. Five subspecies are recognised, differing mostly in their dorsal patterns, in particular the shape and colour of hindwing greenish-blue patch. Mitochondrial DNA sequences (COI) were obtained for three of them. The nominate subspecies is found in the central part of the range, in the Sierra Nevada and La Culata. The other subspecies are found as follows: C. opalinus dominici n. ssp.; in the Santo Domingo valley in the centre-north; C. opalinus cristalinus n. ssp. in the north; C. opalinus iosephi n. ssp. on the eastern slopes, and C. opalinus rosalinus n. ssp. in the southern Páramo El Batallón massif. A hybrid zone between the latter two subspecies was detected in the northern part of the Batallón massif based on unusual individual variation and intermediate phenotypes. All the populations of Cheimas opalinus occur in the forest-paramo ecotone at 2800-3400 m a.s.l., with the notable exception of C. opalinus cristalinus n. ssp. found also in mid-elevation forests down to 2300 m a.s.l.

A preliminary assessment of barcode data for the genus Rhamma suggests the presence of several cryptic species in Colombia. Based on morphology and barcodes, we were able to diagnose one of these lineages as a new species that is described herein as Rhamma dawkinsi, sp. nov. Adult specimens and the genitalia of both sexes are illustrated and compared with R. adunca (Draudt, 1919) and R. comstocki (Johnson, 1992), the most closely related species based on phenotypic appearance.
