This taxon is placed in the nigrus species group by the presence of both a spike-like lateral subterminal apophysis (LSA) and a well-developed proximal retrolateral lobe (pRL) of the male pedipalp. A map with the known distribution of the nigrus species group of Pachomius is presented.

A distribution map is included with both new and previously published records.

This is the first record of the genus from the northern hemisphere of South America. A distribution map is included with both new and previously published records.

In this contribution the female of the jumping spider Lyssomanes miniaceus is described and its morphology is illustrated. Females are distinguished by having spherical, slightly oval spermathecae, the copulatory openings towards the back, and sparse white hairs ventrally on femora I and II; the last character could be a unique trait shared by both sexes. Additionally, a new southernmost record plus new illustration of the little-known species L. belgranoi are given.

A first record of the jumping spider genus Tanybelus (Salticidae: Salticinae: Sarindini) from Col... more A first record of the jumping spider genus Tanybelus (Salticidae: Salticinae: Sarindini) from Colombia is presented, with a new record of T. aeneiceps Simon, 1902 from the Cundinamarca department, in the municipalities of Albán and San Antonio de Tequendama. This is the first record of the species after its original description, more than 100 years ago. Additionally, diagnostic illustrations of the body and copulatory organs, a map with its known distribution and notes of its natural history are also given.

This is the first record of the genus Ceriomura from Colombia. A map is included to show the reported distribution of this South American genus.

Additionally, some interesting variations of the abdomen sculpturing and coloration are illustrated.

In a taxonomic study on jumping spiders from Colombia, nineteen new species of Amphidraus Simon, 1900 were found, all of which with small-scale endemic distributional patterns. Sixteen of these new species are described from the Andean region, eight of which being restricted to the Cundiboyacense high-Andean plateau (A. bochica sp. nov., A. guatavita sp. nov., A. mae sp. nov., A. pae sp. nov., A. sie sp. nov., A. sotairensis sp. nov., A. tisquesusa sp. nov. and A. tundama sp. nov.), in the Boyacá and Cundinamarca departments. The eight remaining Andean species are distributed out of this high-Andean plateau, in the Eastern Mountain Range of Boyacá (A. chie sp. nov., A. somondoco sp. nov. and A. sua sp. nov.), Cundinamarca (A. quinini sp. nov. and A. zaque sp. nov.), Huila (A. guaitipan sp. nov.) and Santander (A. zipa sp. nov.) departments, and in the Central Mountain Range of Risaralda department (A. quimbaya sp. nov.). Additionally, A. sikuani sp. nov. is described from the Eastern department of Meta, and A. colombianus sp. nov. and A. tanimuca sp. nov. from the Amazonian department of Vaupés. Finally, a map with these new records is included, along with a short comment about conservation of biota in the Andean region.

The third species, H. varzea sp. nov., is described from a várzea forest in the Amazonas department. The new species are diagnosed based on sexual characters, such as the retrolateral tibial apophysis, retroventral tibial apophysis and the embolus (male palp), and length and disposition of the copulatory ducts and digitiform glands (epigyne).

Both L. perafani n. sp. and S. felca n. sp. are described from the Narino department, Southwestern Colombia, and both of them are known only from males. Additionally given is the description of L. wiwa n. sp., which is based on the male and female specimens collected from a semi-preserved mountain ecosystem in the Magdalena department, Northern Colombia. Also, two new records of lyssomanines from Colombia, i.e. L. consimilis Banks from Cauca and Chocó departments, and L. unicolor (Taczanowski) from the Chocó department, are presented. Furthermore, new faunal data on lyssomanines from the Caribbean and Pacific coasts of the country are provided. A total of 12 species of Chinoscopus, Lyssomanes and Sumakuru are reported from these two regions of Colombia. Finally, distributional maps of lyssomanines from the Caribbean and Pacific coasts of Colombia with these new and previously published records are included.

Additionally, the genus Anasaitis is recorded for the first time from Colombia, with the species A. canalis, from the department of Chocó. Moreover, new records are presented for Maeota serrapophysis from the departments of Magdalena, Quindío and Valle del Cauca, Colombia, with individuals from the southern region presenting a slightly different pattern of coloration in which the prosoma, abdomen and legs have a reticulated brown and gray pattern. New faunistic data from Colombia are also presented for the species M. betancuri and Ilargus galianoae. Finally, a distribution map is presented, including new and previously published records for the taxa treated here.

The specimen reported here presents a telson with a double aculeus, the dorsal one functional. The specimen belongs to Opisthacanthus elatus (Gervais, 1843), a species with a distribution in Panamá and Colombia in low and humid forests.

New generic and specific records are presented from Brazil, Uruguay and Argentina.

These setae differ from others principally by having a small distal oval patch of lanceolate reversed barbs. Males of Kankuamo gen. n. additionally differ by having a palpal bulb organ very divergent from all known species, with many conspicuous keels dispersed across the median tegulum to the tip, mostly with serrated edges. Females differ by having spermathecae with a single notched receptacle, with two granulated lobes and several irregular sclerotized longitudinal striations. The new urticating setae, type VII, is characterized, illustrated and its releasing mechanism is discussed. It is hypothesized that these setae are the first in Theraphosinae subfamily whose release mechanism is by direct contact. Kankuamo gen. n. is described and illustrated on the basis of the type species Kankuamo marquezi Perafán, Galvis & Gutiérrez, sp. n., and their remarkable characteristics, morphological affinities and cladistic relationship are analyzed.

H. vulpinus is recorded from the Cundinamarca and Meta departments, both in urbanized or conserved ecosystems. S. quadratarius is recorded from a highly intervened Páramo ecosystem in the Serranía de Perijá, Cesar department. A map is included with the known distribution for both species.
