Neohydatothrips dosulis sp. n.

( Figs 20 , 55 , 70 )

Female macroptera. Colour: body bicoloured, brown on head, pronotal blotch, metanotum, tergites VII–X and antecostal ridges of tergites II–VII; mesonotum anterior half brown but posterior half light brown; tergites I–IV laterally light brown, suffused with brown medially; femora brown with apex and base yellow, tibia brown with base yellow; anterior third of pronotum and tergites V–VI pale. Antennal segments I–II light brown, III yellowish brown, IV yellowish brown on basal half but brown on apical half, V–VIII brown. Fore wing bicoloured with basal, median and sub-apical brown bands contrasting with three pale areas, median pale area suffused with brown.

Structure: Occipital apodeme close to, but not confluent with posterior margin of compound eyes ( Fig. 20 ); ocellar setae pair III within ocellar triangle, ocellar triangle transversely striate with internal markings between the striae; pronotum striate with a few markings between the striae, pronotal blotch distinctively dark brown; mesonotum striate, median setal pair anterior to the lateral; metanotum anterior half transversely striate, posterior half longitudinally striate, with markings between the striae, two pairs of setae at anterior margin; metasternal plate with distinct anterior emargination ( Fig. 55 ); fore wing with sub-apical lobe; second vein with no setae ( Fig.70 ); tergites II–VI posterior margin with comb of microtrichia incomplete medially, VII–VIII with comb complete; tergite IX with 2 pairs of mid-dorsal setae; sternites III–VI with discal microtrichia medially, absent medially on VII.

Measurements (holotype female in microns): Body length 1140, Head length 55, width 168; ocellar setae III length 20. Pronotum length 128, width 205. Fore wing length 820. Antennal segments I–VIII length 20, 38, 58, 58, 48, 53, 8, 13.

Male macroptera. Similar to female, but smaller. Sternites without pore plates.

Measurements (paratype male in microns): Body length 785, Head length 38, width 142; ocellar setae III length 15. Pronotum length 100, width 173; pa setae 30. Fore wing length 590. Antennal segments I–VIII length 23, 34, 48, 54, 30, 45, 10, 10.

Material studied. Holotype female. BRAZIL, Rio Grande do Sul State, Cachoeirinha , sweeping net near rice crop, 3.xi.2004 (E.N. Rodrigues) ( UFRGS).

Paratypes. BRAZIL , Rio Grande do Sul State, Cachoeirinha , 1 female and 1 male collected with the holotype (E.N.Rodrigues) , Cachoeira do Sul , 2 females from rice, 11.x.2004 (E.N. Rodrigues) , Eldorado do Sul, 1 female from Pitfall trap, 17.ix.2009 (L. Pogdaiski) ( UFRGS).

Comments. This species is remarkable for the distinctive dark pronotal blotch in contrast to the pale anterior third of pronotum. Along with N. maculicolis , it is one of two species considered here that has a sub-apical lobe subtending the apical seta on the fore wing.
