Sangeeta linnavuorii sp. nov.

Figs 537–538.

Male (color). Pale brown. Antennal pits, two spots on hind margin of vertex closer to eyes than to each other, two spots on anterior shallow depressions of pronotum joined by marginal band, two spots behind eyes, two triangular spots on posterior half of pronotum, median stripe on scutellum anterior to median impressed line, and two small spots laterad of median impressed line, black. Submarginal band on frontoclypeus, inverted Y, circle surrounding each ocellus, median stripe on pronotum, two triangular spots on basal angles scutellum, forewing cells, first M, R and claval cells, fuscous.

Morphology. Anterior pronotal depressions shallow, pronotum shorter than median length of scutellum. Inner anteapical cell closed posteriorly, third apical cell stalked posteriorly.

Male genitalia. Pygofer caudodorsally broadly pointed, ventrally rounded, notched in middle. Styles as in Fig.537. Aedeagus with arms of dorsal apodeme narrower than in S. fyanensis , measuring 0.17 mm in width in cephalic view. Shaft curved anteriorly about middle, with pair of short horn-like processes directed anteriorly, almost reaching caudal margin of gonopore; processes appear finger-like in lateral view; width of aedeagal shaft at point of origin of process in lateral view 0.7 mm.

Female (color). Paler than male, lacking smaller black spots and fuscous markings. Scutellum longer than median length of pronotum. Inner anteapical cell of forewings open basally, third apical cell not stalked.

Measurements. 5.3 mm long 1.6 mm wide across eyes. Female 5.7 mm long, 1.8 mm wide across eyes.

Material examined. VIETNAM: HOLOTYPE ♂, Khontum, N. of Pleiku, 550m, 13.v.1960, L.W.Quate ( BPBM) . PARATYPE: 1 ♀, same data as holotype ( BPBM) .

Remarks. S. linnavuorii closely resembles S. fyanensis but can be distinguished from it by the dorsal horn-like projection of aedeagal shaft. This species is named after Dr R. Linnavuori, a well-known hemipterist.
