Chen, Fangying, Dai, Wu & Zhang, Yalin, 2015, Review of species of the Scaphoideus albovittatus group (Hemiptera, Cicadellidae, Deltocephalinae) from China, with a checklist and distribution summary for Chinese species in the genus, Zootaxa 3904 (3), pp. 334-358 : 335

Scaphoideus Uhler

Scaphoideus Uhler, 1889: 33 . Type species: Jassus immistus Say.

Hussa Distant, 1908: 68 . Type species: Hussa insignis Distant , by original designation.

Bolanus Distant, 1918: 18 . Type species: Bolanus baeticus Distant , by original designation. For the relationships and diagnosis of Scaphoideus see Oman (1949), Barnett (1977) and Viraktamath & Mohan (2004).

Remarks. As mentioned in the description given by Viraktamath and Mohan (2004), the species of Scaphoideus differ widely in colour and male genitalia, and can be divided into three groups according to coloration: (1) body ochraceous to brown with a median longitudinal yellowish or whitish stripe extending to folded front wings; (2) body with transverse bands on vertex, pronotum and scutellum; (3) body with dark brown spots or bands on vertex, and longitudinal bands on pronotum and scutellum. In the first group, here referred to as the Scaphoideus albovittatus group, species are very similar in coloration and difficult to distinguish externally. Based on the number of spots on vertex and male genitalia, they can be divided into two morphotypes: 1) Vertex pale with four spots; style with preapical lobe not developed; subgenital plate with blunt distal end; and aedeagus without process, including S. rostratus sp. nov., S. albovittatus Matsumura and S. katraini ; 2) Vertex pale with three spots; style with preapical lobe well developed; subgenital plate with round distal end and aedeagus with pair of processes; including other nine species as in checklist.

The known females of Chinese species of the Scaphoideus albovittatus group can be distinguished from each other mainly by the following characters: the posterior margin of sternite VII is well produced medially and forms a median lobe in S. coniceus ( Fig. 4 B, F), S. maai ( Fig. 4 D, H), S. intermedius and S. kumamotonis ( Fig. 4 C, G), and the former species has the projection slightly elongated ( Fig. 4 B, F), the last species has the projection conspicuous more elongated with a notch in the middle ( Fig. 4 C, G); in S. albovittatus ( Fig. 4 A, E), the sternite VII is broadly convex and lacks a distinct median lobe, and deeply incised in the middle. Other characteristics are similar among females.
