Neohydatothrips gaucho sp. n.

( Fig. 24 )

Female macroptera. Colour: body yellow, but brown on ocellar area, mesonotum, metanotum, antecostal ridges of tergites II–VII, lateral thirds of tergite II and anterolateral areas of III. Antennal segments I–II yellow, III yellow with apex brown, IV–V yellow with apical third brown, VI–VIII brown. Pronotal blotch light brown. Fore wing bicoloured with basal, median and subapical brown bands in contrast to pale areas.

Structure: occipital apodeme distant from posterior margin of compound eyes, ocellar setae pair III near margins of ocellar triangle, ocellar triangle smooth with very week striae ( Fig. 24 ); pronotum striate with blotch pale ( Fig. 24 ); mesonotum striate, median setal pair anterior to the lateral; metanotum anterior half transversely striate, posterior half longitudinally striate, two pairs of setae on anterior margin; metasternal plate with very shallow anterior emargination; fore wing second vein with no setae; tergites II–V with posteromarginal comb of microtrichia incomplete medially, VI with irregularly spaced small teeth medially and VII–VIII with comb complete; tergite IX with 2 pairs of mid-dorsal setae; sternites III–VII with no microtrichia medially, few laterally.

Measurements (holotype female in microns): Body length 1020, Head length 93, width 150; ocellar setae III length 18. Pronotum length 105, width 163, pa setae 37. Fore wing length 650. Antennal segments I–VIII length 23, 35, 46, 45, 38, 53, 8, 10.

Material studied. Holotype female, BRAZIL, Rio Grande do Sul State, Cambará do Sul, Parna Aparados da Serra , on Baccharis cf. trimera 27.i.2013 (A. Cavalleri) ( UFRGS) .

Paratype. BRAZIL, Rio Grande do Sul State, Eldorado do Sul , 1 female from net sweeping, 15.xii.2010 (L. Podgaiski) ( UFRGS).

Comments. This bicoloured species has a colour pattern that resembles N. flavicollis , from which it can be distinguished easily by its yellow head with the ocellar area brown and weak sculpture lines, and the greater distance of the occipital apodeme from the compound eyes.
