Cambalida tuma View in CoL sp. n.

( Figs 4A–K View FIGURE 4 A – K , 5A–E View FIGURE 5 A – E. A , 6A–E View FIGURE 6 A – 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 View FIGURE 5 A – E. A , 6A–C View FIGURE 6 A – E ) (tegular tip of C. loricifera with less prominent apico-retrolateral bulging, see Haddad 2012: fig. 56); embolus with apico-prolateral origin ( Figs 5C View FIGURE 5 A – E. A , 6C View FIGURE 6 A – E ) (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 View FIGURE 5 A – E. A , 6C View FIGURE 6 A – E ) (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 View FIGURE 5 A – E. A , 6C View FIGURE 6 A – E ) (embolic tip in C. loricifera is narrow, angular, see Haddad 2012: figs. 56, 91); and copulatory ducts without median curve ( Figs 5D, 5E View FIGURE 5 A – E. A , 6D, 6E View FIGURE 6 A – E ) (in C. loricifera , copulatory ducts with median curve, see Haddad 2012: figs. 89, 90).
