Viraktamath, C. A. & Mohan, G. S., 2004, A revision of the deltocephaline leafhopper genus Scaphoideus (Hemiptera: Cicadellidae) from the Indian subcontinent, Zootaxa 578, pp. 1-48 : 16-17

Scaphoideus consanguineus Distant

Fig. 46

Scaphoideus consanguineus Distant 1908b: 375 . HOLOTYPE Ψ, INDIA [BMNH, examined].

Coloration as in S. coloratus and as described by Distant (1908b). Claval veins close together but not connected by a cross vein. Three spots on clavus and apex of front wing dark brown.

Female genitalia: Hind margin of seventh sternum slightly concave medially with a median V­shaped notch.

Material examined: INDIA: Holotype Ψ, “ Type, H.T. (on a circular disk with red margin)” “ 2­8­06, N. Annandale, Calcutta” “ Scaphoideus congsanguineus Dist. type ” ( BMNH).

Remarks: S. consanguineus is known only by the type and belongs to Scaphoideus . However, its relationship with other species cannot be established until the discovery of the male.

Scaphoideus decoratus Rao and Emiliyamma Figs 47–53 .

Scaphoideus decoratus Rao and Emiliyamma, 1995: 80 –81. HOLOTYPE ɗ, INDIA [ZSI, examined]

Coloration as described by Rao and Emiliyamma (1995) and similar to that in S. coloratus .

Male genitalia: Pygophore without process, height to length ratio 1:1.25. Subgenital plate triangular, with distal end acutely pointed, 2.5 times as long as basal width, with three long stout setae arranged in an oblique row. Style with apophysis short, 0.33 as long as total length, laterally curved, with bird­headlike apex. Connective with arms as long as stem; paraphyses strongly converging at basal 0.33 then parallel, each paraphysis slightly twisted at apical 0.33 and then tapering to apex. Aedeagus compressed, with lateral ridges, dorsal apodeme well­developed, dorsal connectives well­developed, and stout, gonopore elongate on ventral margin.

Material examined: INDIA: Holotype ɗ, Madumalai, 13.ii.1992, G. Thirumalai coll. (ZSI). Paratype: 1 ɗ, data as holotype (ZSI).

Remarks: S. decoratus is similar to S. colorata and S. sabourensis Rao and Ramakrishnan as they all share an apically twisted apophysis. S. decoratus differs from the two species in having a compressed aedeagal shaft.
