The Sri Lankan species of the genus Carrhotus Thorell,1891 have remained taxonomically unrevised. The present study reviews all species of the genus in the island. Here we describe and diagnose three new species: Carrhotus albosetosus sp. nov. (♀), C. atratus sp. nov. (♂♀) and C. lobatus sp. nov. (♂). Further, C. silanthi Caleb, 2020 is reported in Sri Lanka for the first time. Carrhotus taprobanicus Simon, 1902 and C. viduus (C.L. Koch, 1846) are redescribed based on material from Sri Lanka. A key to the Carrhotus species in Sri Lanka is given.
A new genus of jumping spiders, Bavirecta gen. nov. is proposed to include the type species B. flavopuncta gen. et sp. nov. and Bavirecta exilis (Cao et al., 2016) gen. et comb. nov. Distinguishing characters of Bavirecta gen. nov. include: 1) tubular abdomen, 2) enlarged front legs, 3) straight and
pointed embolus, broadest proximal lobe with black blotches, 4) prolateral tegular lobe, 5) widely separated anterior atria. Furthermore, two new species, Schenkelia aurantia sp. nov. (♂♀) and Brancus calebi (♂) sp. nov., are described and diagnosed. Mogrus frontosus (Simon, 1871) is redescribed based on a male collected from Mandaitivu Island of Jaffna District in Sri Lanka. The genera Brancus Simon, 1902, Mogrus Simon, 1882 and Schenkelia Lessert, 1927 are reported for the first time from Sri Lanka
(Brancus and Schenkelia are recorded for the first time outside Africa).
