Phenasurya daeng, a new genus and species of plexippine jumping spider (Salticidae, Plexippini, Plexippina) from Thailand

We describe a new plexippine genus and new species, Phenasurya daeng gen. et sp. nov., with a striking red face, from Thailand. Its placement within Plexippina is supported by ultraconserved element (UCE) - based phylogenomic analyses, supplemented with a broader four-gene analysis. Morphological evidence further justifies its generic status.

Phenasurya daeng is recovered near cf. Colopsus and Pancorius but is morphologically distinct from both. These findings reveal a new red-faced lineage and settle the identity of a perplexing jumping spider.
