description: Cambalida tuma sp. n.
(Figs 4A–K, 5A–E, 6A–E)
Type material. Holotype: ♂ (ADSH 18101A), INDIA: Gujarat: Narmada: Dediyapada, 21°37'36.39"N, 73°35'09.29"E, 172 m a.s.l., D.A. Prajapati leg., 17 June 2015, by hand from the ground; Paratypes: 7 ♀ (ADSH 18101B), same data as holotype.
Etymology. The specific epithet is an adjective derived from the prominent apico-retrolateral bulging of the tegular tip, which is unique to the species. Latin tumes = bulging.
Diagnosis. Cambalida tuma sp. n. is most similar to C. loricifera (Simon, 1886), but can be distinguished by the following combination of characters: tegular tip with a prominent apico-retrolateral bulging (Figs 5A–C, 6A–C) (tegular tip of C. loricifera with less prominent apico-retrolateral bulging, see Haddad 2012: fig. 56); embolus with apico-prolateral origin (Figs 5C, 6C) (in C. loricifera, embolus originates apico-medially, see Haddad 2012: figs. 56, 91); median embolic turn long and transverse to the longitudinal axis (Figs 5C, 6C) (in C. loricifera, median embolic turn short and oblique to the longitudinal axis, see Haddad 2012: figs 56, 91); comparatively thick, blunt embolic tip (Figs 5C, 6C) (embolic tip in C. loricifera is narrow, angular, see Haddad 2012: figs. 56, 91); and copulatory ducts without median curve (Figs 5D, 5E, 6D, 6E) (in C. loricifera, copulatory ducts with median curve, see Haddad 2012: figs. 89, 90).
Description. Male in alcohol (holotype, Figs 4A–E): In colouration and general shape, like the male of Cambalida deorsa sp. n. except brownish segments of legs III and IV. Body length 4.01.

Pedipalp (Figs 5A–C, 6A–C): Palpal segments brownish; cymbium/tarsus apically with six stout setae on dorsal surface, arranged in three rows (2–2–2); apical cymbium unusually modified as a ‘thick cone’ (Figs 5A, 6A).
