“…Methodology and taxonomic descriptions are based on the format of Benjamin and Kanesharatnam (2016), Kanesharatnam and Benjamin (2016), and Benjamin (2004, 2010). Sampling was primarily done by beating vegetation up to a height of approximately 1.5 m. Specimens for the morphological study were preserved in 70% ethanol and identified using an Olympus SZX7 stereomicroscope.…”

This study presents a systematic revision of South Asian members of the Tribe Chrysillini Simon, 1901. Genetic and morphological variations were analysed of a “similar-looking” group of species that were initially identified as members of the jumping spider generaChrysillaThorell, 1887 andPhintellaStrand, in Bösenberg and Strand 1906 to determine their phylogenetic relationships. Results suggest that the assessed morphospecies complex constitute of three evolutionary lineages, two previously unrecognised, which are described and diagnosed as two new genera:Phintelloidesgen. n.andProszynskiagen. n.The third lineage,Phintella, is sister to these proposed genera. The following new species are described:Phintelloidesalboreasp. n.,P.brunnesp. n.,P.flavovirisp. n.,P.flavumisp. n.,P.orbisasp. n.,Phintellaargenteasp. n., andP.jaleelisp. n.Sri Lanka is rich in biodiversity but currently has one of the highest rates of deforestation. Lack of clarity on diversity and distribution of the islands’ biodiversity can lead to underestimations during threat assessments and thus downgrading of conservation needs of individual species.

“…Taxonomic studies are necessary to document biodiversity and provide base data for effective nature conservation (Alvarez-Padilla et al 2015). Field work conducted by us during last few years have shown the presence of an abundant, largely unexplored spider fauna living in the forest patches of the island (Ranasinghe andBenjamin 2016a, b, c, 2018;Kanesharatnam and Benjamin 2016;Benjamin and Kanesharatnam 2016, in press;Batuwita and Benjamin 2014). This now concluded project on Sri Lankan Oonopidae was initiated to discover new species (Ranasinghe andBenjamin 2016a, b, c, 2018;Ranasinghe 2017) and as a result of this project, 19 new species were discovered from forest habitats across the island (Ranasinghe andBenjamin 2016a, b, c, 2018).…”

Jumping spiders (Salticidae) are a diverse group of non‐web‐building predators and the most species‐rich spider family. The Salticidae Tribe Nannenini consists of a small group of Oriental jumping spiders that are very poorly known. The use of explicit phylogenetic analyses to establish its affinities has so far remained limited. The Nannenini genus Epidelaxia has a peculiar morphology, making its systematic position uncertain. In this study, we present a comprehensive dataset combining molecular and morphological data for Nannenini, including exemplars from all genera. This dataset comprises DNA sequences of approximately 2400 bp, including nuclear genes (18S, 28S and H3) and the mitochondrial gene CO1, sequenced for 40 taxa (20 ingroups and 20 outgroups), along with 61 morphological characters. Notably, both DNA sequences and morphological traits were analysed separately and concurrently for the first time. The Nannenini clade is recovered with high support. Further, Epidelaxia is monophyletic and sister to Tubalaxia gen. n. This is the first hypothesis on the internal phylogenetic structure of Epidelaxia and its placement within the Tribe Nannenini. A new genus Tubalaxia gen. n. and the following new species are described: E. bharathi sp. n., E. somasundaram sp. n., T. castanea sp. n., T. aurea sp. n. The following new combination is proposed: Tubalaxia minuta (Prószyński, 1992) comb. n. Epidelaxia albostellata, E. albocruciata and E. obscura are redescribed. It is worth noting that the newly described species face endangerment due to their limited distribution and small population sizes.
