A new species of jumping spider Neonella Gertsch, with notes on the genus and male identification key (Araneae, Salticidae)

Abstract

The American genus Neonella Gertsch, 1936 consists of very small jumping spiders whose biology is not well known. The genus currently includes eleven valid species, of which eight are known from both sexes and two are only known from one sex. This paper describes and illustrates a new species Neonella acostae sp. n., demonstrates male palpal variation in Neonella montana Galiano, 1988, and provides some information on the ecology of three sympatric species. New records of Neonella montana and Neonella minuta Galiano, 1965 are reported. Because the previously described species of Neonella were well illustrated and diagnosed, a dichotomous key to males is given along with genital illustrations of both sexes for all known species.

Description of the female of Lyssomanes miniaceus, with a new distribution record for L. belgranoi (Araneae: Salticidae)

“…A number of sources were used for this contribution; eight arachnological collections with specimens and records of ten different species of Lyssomanes were revised: Sección Description formats and morphological terms follow Rubio et al (2015) and Zhang and Maddison (2015). Female genitalia were dissected as in Levi (1965), examined after digestion in hot ~15% KOH solution (Ramírez 2014) and clarified in clove oil to study the internal structures.…”
