Scale bars: 2 mm (A, B), 0.1 mm (C–D) Proszynskia is a small genus of south Asian jumping spiders erected by N. Kanesharatnam and Benjamin in 2019 after a molecular phylogenetic study of south Asian spiders showed the relationship between two species previously belonging to Marpissa and Phintella. They are large for jumping spiders, growing up to long. The thin abdomen has a yellow stripe between two black stripes.
The genus is named after Jerzy Prószyński, a major contributor to the knowledge of jumping spiders, and it contains only two species: P. anusuae and P. diatreta. The single most likely cladogram shows that Phintelloides is sister to Phintella, with Proszynskia sister to both:
