Genus Carrhotus Thorell, 1891 View in CoL View at ENA

Type species

Plexippus viduus C.L. Koch, 1846 .

Diagnosis

Carrhotus can be readily distinguished from other salticid genera by the combination of the following characteristics: RTA stout, tegulum with at least a retrolateral and/or proximal lobe, embolus broadbased, tip mostly stout ( Figs 6E–F View Fig 6 , 7A–B View Fig 7 , 8C–D View Fig 8 , 9A–B View Fig 9 , 11E–H View Fig , 12A–B View Fig 12 , 13E–F View Fig 13 , 14A–B View Fig 14 , 15E–F View Fig 15 , 16A–B View Fig 16 ) (C.L. Koch 1846; Simon 1902; Jastrzebski 1999; Caleb et al. 2020: 58, Figs 33–56). Females can be distinguished by the distinctive accessory glands on the external spermathecal walls and well sclerotized FD ( Figs 4A–B View Fig 4 , 7C–D View Fig 7 , 12C–D, 12C–D View Fig 12 , 14C–D View Fig 14 , 16C–D View Fig 16 ). Spermatheca one chambered, oval to kidney-shaped (C.L. Koch 1846; Simon 1902; Jastrzebski 1999; Caleb et al. 2020: 58, Figs 33–56).

Description

Medium sized spiders. Cephalothorax longer than wide, eye field shorter than 50% of total cephalothorax length. PME mid-way between anterior and posterior laterals. Abdomen egg-shaped, beige to brown with a lighter pattern. Chelicerae unident with 2 promarginal teeth and 1 retromarginal tooth. RTA not prominent; cymbium in some species with apical process; tegulum oval, expands beyond apical border of tibia (PLP); embolus stout, set laterally on top of tegulum, wider base. Female epigyne moderately sclerotized, strongly haired. CD well sclerotized, straight, curved or coiled. Spermatheca one-chambered, oval to kidney-shaped. FD is well sclerotized. Accessory glands on external spermathecal walls. Legs I and II robust with scopulae, III and IV more delicate. Hairs and bristles blackish. Leg formula: 1-2-4-3 ( Jastrzebski 1999).

Composition in Sri Lanka

Currently, the genus consists of 33 species worldwide [for a full list see World Spider Catalog (2022)]. The following species are now recorded from Sri Lanka: Carrhotus atratus sp. nov., C. albosetosus sp. nov., C. lobatus sp. nov., C. silanthi Caleb, 2020 , C. taprobanicus Simon, 1902 and C. viduus C.L. Koch, 1846 . Carrhotus silanthi and C. viduus are also known from India.
