Synemosyna aurantiaca and S. nicaraguaensis are recorded for Bolivia for the first time and the previously unknown male of S. nicaraguaensis is described and illustrated. The habitus and the genitalia of the female of S. myrmeciaeformis are illustrated for the first time. Synemosyna aurantiaca occurs in semi-deciduous forests south of 18° S and S. myrmeciaeformis in the Bolivian Yungas forest and ecoregions of the Amazon biome north of 16° S. Synemosyna nicaraguaensis is possibly an Andean species that enters into the moist Isthmian forests of Central America. Several potential mimicry complexes with two broad patterns were observed: sex-specific polychromatic mimicry (S. nicaraguaensis), and transformational mimicry involving smaller orange and larger brown to dark-brown forms (S. aurantiaca and S. myrmeciaeformis).
Three new jumping spiders of the genus Hypaeus Simon, 1900 are described and illustrated from Colombia, two of which are sympatric: H. arhuaco sp. nov. and H. proszynskii sp. nov., from Sierra Nevada de Santa Marta, Magdalena department. 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).
Edwardsya, a new genus of jumping spiders from South America (Araneae: Salticidae: Freyina)
Zootaxa, 2016
Edwardsya gen. nov. is proposed to include the type species Attus simoni Taczanowski, 1871 from lower Amazon River, and E. igapo sp. nov. from upper Amazon River, both known only from Brazil. The male of Edwardsya simoni comb. nov. is redescribed and the correct female is described for the first time. Both sexes of the second species are described and illustrated. A modified endite apophysis is described, and a stimulatory role in copulation is proposed for it.
Species of Scopocira (Araneae: Salticidae) can be recognized by the presence of one apophysis on the prolateral face of the male chelicerae and embolus arising from the retrolateral side of the tegulum in the male palps. While comparing material from Colombia to the illustrations of the revision (Costa & Ruiz 2014), it was possible to identify a new species and the undescribed female of one species described in that paper. The new species is described here, based on specimens collected in the Amazonian department of Vaupés, Colombia. Also, the female of S. crotalica Costa & Ruiz, 2014 is described and illustrated for the first time, based on material from the Amazonian state of Guainía, Colombia. Additionally, S. dentichelis Simon, 1900 and S. tenella Simon, 1900 are also newly recorded from this country.

The spider genera Mystaria Simon, 1895 and Paramystaria Lessert, 1919 are revised (Mystarini: Thomisidae). About 400 individuals were studied. The approach followed was classical taxonomy using illustrated sexual dimorphic copulatory characters and described morphological characters, photographed or measured. Paramystaria is considered a junior synonym of Mystaria, based on similarity to the type M. rufolimbata Simon, 1895 but with the exclusion of M. unicolor Simon, 1895, a species last studied in 1895. Mystaria unicolor is re-described and placed in a new genus, Leroya gen. n., together with L. silva sp. n. (♂♀, DRC) which is recognised as the type species. Mystaria now contains 13 well-defined species, four of which are in new generic combinations. Four males are described for the first time, and eight new species. Re-described species include M.
