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.
