Neohydatothrips dosulis  sp. n.

( Figs 20View FIGURES 15 – 23, 55View FIGURES 50 – 66, 70View FIGURES 67 – 79)

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. 20View FIGURES 15 – 23); 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. 55View FIGURES 50 – 66); fore wing with sub-apical lobe; second vein with no setae ( Fig.70View FIGURES 67 – 79); 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) ( UFRGSAbout 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) ( UFRGSAbout 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.
