Thrips coprosmae Mound

Thrips coprosmae Mound, 1978: 618

Diagnosis: Colour variable, light to dark brown or bicoloured, forewing pale, antennal segments III–VII darker brown than I–II. Antennae 7­segmented; ocellar setae III relatively long and arising outside ocellar triangle ( Fig. 15 ). Pronotum almost without sculpture; fore tarsus with pre­apical claw. Metanotum with irregular reticulation ( Fig. 16 ), median setae behind anterior margin, campaniform sensilla absent. Forewing first vein with complete row of setae; clavus with 5 marginal setae, termina and subterminal setae sub­equal. Abdominal tergite II with 3 lateral setae; tergite VIII with marginal comb complete, microtrichia irregular and in groups; pleurotergites with 2 or 3 discal setae ( Fig. 17 ), sternite II with 3 pairs of marginal setae, sternites III–VII with 5 to 10 discal setae.

Breeding: Adults and larvae have been taken from the young leaf buds of Coprosma robusta , C. rotundifolia and C. pseudocuneata ( Martin & Mound, 2005) .

Distribution: A New Zealand endemic, this species is widespread in both North and South Islands.

Relationships: A member of the Thrips obscuratus group ( Mound, 2005), in which five species from New Zealand and three from New Caledonia share the unusual apomorphy of the second abdominal sternite bearing three pairs of marginal setae.
