Euplocania (Psocodea: Ptiloneuridae) in Peru, description of six new species.

Based on a review of specimens from Peru, six new species of the Euplocania (Ptiloneuridae) were found and assigned to species groups. The new species, here described and illustrated are: Euplocania alfonnerii n. sp., E. amarui n. sp., E. garcialdretei n. sp., E. katarii n. sp., E. matsiguenka n. sp. and E. wchipere n. sp. An identification key for Euplocania from Peru is included.

New species of Myopsocidae (Insecta: Psocodea: Psocoptera) from Colombia.

To broaden the knowledge of the diversity of Myopsocidae (Psocomorpha: Psocetae) in the neotropical region, a review of specimens collected in the last 12 years by the Entomological Research Group (GIE) was carried out. Twenty-six species belonging to the genera Lichenomima and Myopsocus were found, of which 22 are new to science and are here described and illustrated, they are: Lichenomima bonaverensis n. sp., L. gorgonaensis n. sp., L. guapiensis n. sp., L. huilensis n. sp., L. iscuande n. sp., L. lienhardi n. sp., L. occidentalis n. sp., L. pearmani n. sp., Myopsocus amacayacu n. sp., M. amazonensis n. sp., M. andaquies n. sp., M. caliensis n. sp., M. caquetensis n. sp., M. chocoensis n. sp., M. colombianus n. sp., M. garcialdretei n. sp., M. inga n. sp., M. insularis n. sp., M. katios n. sp., M. panchei n. sp., M. putumayensis n. sp. and M. tukunare n. sp. Four species, L. onca Mockford, L. ariasi (New), M. minor (New & Thornton) and M. minutus (Mockford), are also recorded from Colombia. A key for the determination of South American species is also presented.

Changes in the genus Euplocania (Psocodea: Ptiloneuridae): invalidation of the species group Marginata and establishment of the species group Uariniensis, with description of two new species.

The recent examination of the morphology of the wings, hypandrium and phallosome, of Brazilian and Colombian species of Euplocania, initially assigned to the species group Marginata, suggested that the group was wrongly established and therefore, must be removed. As a consequence, the new species group Uariniensis is proposed to include E. atlantica Silva-Neto, E. uariniensis Silva-Neto, Garca Aldrete Rafael and E. macuxi Pereira, Silva-Neto Boldrini, in addition to the two species described in this paper: E. guticortesorum n. sp. and E. wilsoni n. sp. The number of species in Euplocania is raised to 53. A key for the determination of the species (males) of the group Uariniensis is also included.

The genus Ptiloneura (Psocodea: Ptiloneuridae) in Valle del Cauca, Colombia, altitudinal distribution, new records, and description of two species.

From recent collections of psocids in natural areas of Valle del Cauca, Colombia, new records and two new species of the genus Ptiloneura were found. The latter are described and illustrated: P. elduende n. sp., and P. pichindensis n. sp., that correspond to a subclade previously named as genus Loneuroides. A map with the geographical and altitudinal distribution of the species in the department of Valle del Cauca, and a key for the determination of the species (males) in this subclade are presented.

New species of Triplocania Roesler (Psocodea: Psocoptera: Ptiloneuridae) from Colombia and Peru.

Based on a survey of species of the genus Triplocania (Psocodea: Psocoptera) in forests of natural areas of Colombia and Peru, 18 species (14 from Colombia and 4 from Peru) were found, 16 of which are new to science and two correspond to males of Colombian species originally described from females (T. matildae Gonzlez et al., 2017, and T. sarriae Gonzlez et al., 2017). The new species, here described and illustrated are: T. altamira n. sp., T. antioquensis n. sp., T. antisuyuensis n. sp., T. atratoensis n. sp., T. caguanensis n. sp., T. caquetensis n. sp., T. einsteini n. sp., T. fabridiazi n. sp., T. galileii n. sp., T. hawkingi n. sp., T. mancocapaci n. sp., T. molanoi n. sp., T. nerudai n. sp., T. roesleri n. sp., T. tahuantisuyuensis n. sp., and T. yupanquii n. sp. The number of species of Triplocania is now raised to 118. To date, the highest number of species are found in Colombia, Brazil and Peru, with 59, 34 and 9 species respectively. An updated identification key to the species of Triplocania (males) is included, as well as a classification of the species in the genus.

A new genus of Ptiloneuridae, its position within the family, and descriptions of five species (Psocodea, 'Psocoptera').

Upon examination of ptiloneurid specimens recently collected in forests of natural areas and Natural National Parks in Colombia, ten males and seven females were found that represent five species of an undescribed ptiloneurid genus. It differs from the other genera in the family by characters of the wings, hypandrium, phallosome, epiproct, female gonapophyses, and sternum IX. An identification key to the males of the genera of Ptiloneuridae, and a key to the species of the new genus are presented. A test on the validity and monophyly of the new genus, and its position within the family was also conducted.

New species of Colombian Triplocania Roesler (Psocodea: 'Psocoptera': Ptiloneuridae).

Based on a survey of the genus Triplocania (Psocodea: 'Psocoptera') in forests of natural areas and Natural Parks in Colombia, 46 species were found, 42 of which are new to science and are here described and illustrated. Added to T. colombiana García Aldrete, the number of species of Triplocania now known in Colombia is raised to 47. To date, 40 species described in this paper are recorded only in Colombia, and seven species are shared with neighboring countries, three with Brazil, one with Venezuela, two with Ecuador, and one with Ecuador and Brazil. Females of three previously known species are also described. An identification key to the species of Triplocania present in Colombia is included.
