Scaphoideus quangtriensis sp. nov.

( Figs 15, 16 , 18 )

Length: ♂, 4.2 mm (x 1 specimen)

Yellow marked with orange on vertex and disc of pronotum and scutellum; a narrow brown band on face below ocelli and three laterally on pronotum. Forewing with a small brown spot in third apical cell.

External features as in S. dellagiustinai ( Figs 1–3 ). Head relatively narrow in dorsal view with vertex slightly longer than basal width; fore margin of the head truncate in lateral view; clypeus narrow dorsally and antennae situated relatively high on face. Forewing with two recurved costal veins from outer subapical cell.

Male genitalia with pygofer, subgenital plate and connective as in S. dellagiustinai ( Figs 5, 8–9 ): pygofer without processes, broadly rounded apically in lateral view with a group of very long setae apically and a few shorter setae subapically. Subgenital plate distinctly shorter than pygofer, broad basally with distal two thirds very narrow in ventral view; a uniseriate row of macrosetae subbasally and a few short fine setae distally. Connective with a pair of slender paraphyses, each paraphysis tapering distally. Style as in S. dellagiustinai ( Fig. 4 ) but apical process more elongate. Aedeagus disassociated from connective; shaft elongate, slightly longer than basal apodeme, with a pair of short apical processes and a dorsal serrated flange basally on each side, gonopore apical on posterior surface; basal apodeme compressed anteroposteriorly, produced into a lobe on each side at midlength ( Figs 15, 16 ).

Material examined. Holotype ♂, VIETNAM: 1 mile N. of Quang Tri, 11.vii.1970, A. R. Gillogly , white light ( BMNH).

Remarks. This species is similar to S. rubroguttatus and S. unimaculatus in the male genitalia but can be distinguished by its slightly more robust aedeagal shaft in lateral view with basal flanges less well developed.
