For the first time a hypothesis of homology is proposed for the macrosetae which compose the armature of the distal truncus penis of the Gonyleptoidea. Previous attempts to name them in the literature have not been continued because they started by referring to macrosetae based on their position, which may change widely, and all of them were very narrow in scope. The present project instead names groups of macrosetae that do not mandatorily refer to their position, thus compensating for their hypothesized secondary position shifts. Using criteria of topology, shape and exclusion, six groups of setae are recognized, A–E, and their topological and phylogenetic distribution is studied and described in all families of Gonyleptoidea and two other related families of Grassatores. A cladistic analysis is performed, providing the following results: (1) the Microsetata are recovered including Metasarcidae/Cosmetidae sister to an expanded Gonyleptidae; (2) the genera Quindina (Cranaidae) and Zygopachylus (Manaosbiidae) are transferred to Nomoclastidae rank nov., hitherto regarded as a subfamily of Stygnidae, now a sister group of the Microsetata; (3) Zamorinae, currently placed in Cranaidae, is the sister group to Nomoclastidae, and it is therefore transferred to this family; (4) an expanded Gonyleptidae is recovered, including Manaosbiidae and Cranaidae, but the independence of these families is also recovered because the Gonyleptidae stricto sensu form a clade; (5) the Ampycinae, in spite of many particularities, are recovered inside Gonyleptidae; (6) the zamorine‐less Cranaidae are recovered as a monophyletic sister group to Gonyleptidae, but not nested inside it. Jabbastygnus gen. nov. is described in Stygnidae along with its type species J. huttorum, from Colombia. © 2015 The Linnean Society of London

A new species belonging to the schizomid genus Piaroa Villarreal, Giupponi and Tourinho, 2008 is described from north-western Venezuela. A complementary description of Piaroa guipongai Villarreal and Garcia, 2012 is provided including SEM pictures of relevant structures of both sexes. A key for males of Piaroa and Colombiazomus Armas and Delgado-Santa, 2012 is included. The presence of Dm3 setae on Hubbardiidae is discussed.

A new genus, Calima, and two new species, C. bremensis and C. valenciorum, of Hubbardiidae are here described,respectively from Bremen Forest, Filandia, Quindio department and Andinapolis, Trujillo, Valle del Cauca department,both localities located in the Colombian Andes. A comprehensive map of the South American species with a four-segmented female flagellum is presented, tables with characters of New World Hubbardiidae genera are provided. The relationships of the new genus within neotropical Hubbardiidae fauna is discussed.

The Cranaidae genus Phalangodus Gervais, 1842 is revisited and its species are diagnosed. An identification key for the males of Phalangodus is provided. Four Colombian species are described as new: Phalangodus briareos sp. nov. from a cave in Zapatoca, Santander department, P. cottus sp. nov. from Villavicencio, Meta department, P. gyes sp. nov. from Ibagué, Tolima department and P. kuryi sp. nov. from Sierra Nevada de Santa Marta, Magdalena department. SEM images of the penis of Phalangodus, including the type species of the genus, P. anacosmetus Gervais, 1842, are provided for the first time. Sexual dimorphism and the morphology of stylar caps and ovipositor in Cranaidae are discussed. Additionally, we revised the geographical distribution of P. anacosmetus, including a map with the geographical records of the genus.
