Thrips sumatrensis Priesner

Thrips (Isoneurothrips) sumatrensis Priesner, 1934: 254 Diagnosis: Body and femora brown to dark brown, tibiae yellow with brown shadings; antennal segment III yellow, IV–V yellow at base; forewings brown with base pale. Antennae 7­segmented; ocellar setae III long, arising anterolateral to ocellar triangle (Fig. 93); postocular setae I about twice length of setae II & III. Pronotum with transverse markings and about 20 small discal setae. Mesonotum with no lines of sculpture close to anterior campaniform sensilla. Metanotum transversely striate on anterior half, with longitudinal striations on posterior half, median setae arise at anterior margin, campaniform sensilla present. Forewing first vein with setal row irregular, commonly with up to 12 setae on basal half then about 5 setae variably spaced on distal half, clavus with terminal and subterminal setae subequal in length. Abdominal tergite II with 3 (or 4) lateral setae; tergite VIII comb complete but short and irregular; sternites III–VII with 9–16 discal setae. Male yellow, sternites III–VII with about 9 discal setae in row posterior to transverse glandular area.

Breeding: Recorded from the flowers of a wide range of plant species in Asian countries, the only record in Australia is from the flowers of a Solanum species near Brisbane in October 1985 .

Distribution: Widespread from South East Asia to the Pacific, including Thailand, Guam and Tahiti, this species is recorded from Australia on a single series of females taken in Queensland near Brisbane, and has also been seen from New Caledonia (in SMF).

Relationships: Closely related to T. hawaiiensis , this species has a more extensive, but irregular, row of setae on the first vein of the forewing, and ocellar setae III are unusually elongate.
