Neohydatothrips sulcus  sp. n.

( Figs 41View FIGURES 41 – 49, 63View FIGURES 50 – 66)

Female macroptera. Colour: body mainly yellow with ocellar area shaded light brown, antecostal ridges on tergites II –VI brown with yellowish brown areas posterolaterally; antennal segment I yellow, II yellowish brown, III light brown with base and apex brown, IV light brown on basal half but brown on apical half ( Fig. 63View FIGURES 50 – 66), V brown with base light brown, VI –VIII brown; fore wing uniformly pale brownish grey.

Structure: Occipital apodeme not touching posterior margin of compound eyes; ocellar setae pair III on external margins of ocellar triangle, ocellar triangle smooth ( Fig. 41View FIGURES 41 – 49); pronotum closely striate with indistinct blotch ( Fig. 41View FIGURES 41 – 49); 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 two setae; tergites II –VI with comb of microtrichia incomplete medially, comb complete on VII –VIII; tergite IX with 2 pairs of mid-dorsal setae; sternites III –VII with no microtrichia medially.

Measurements (holotype female in microns): Body length 985, Head length 65, width 148; ocellar setae III length 20. Pronotum length 110, width 175. Fore wing length 600. Antennal segments I –VIII length 20, 33, 43, 38, 35, 38, 5, 8.

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

Measurements (paratype male in micros): Body length 720, Head length 53, width 130; ocellar setae III length 13. Pronotum length 98, width 135. Fore wing length 470. Antennal segments I –VIII length 15, 30, 40, 29, 24, 26, 3, 5.

Material studied. Holotype female. BRAZIL, Rio Grande do Sul State, Santo Antônio das Missões, 1 female from Vachellia caven  (labelled as Acacia caven  ) 3.ii.2013 (A. Cavalleri) ( UFRGSAbout UFRGS). 

Paratypes. BRAZIL, Rio Grande do Sul State, Santo Antônio das Missões, 2 males and 2 females collected with the holotype, 3.ii.2013 (A. Cavalleri), Barra do Quaraí , 1 female and 1 male from same host as holotype, 18– 19.ix.2003 (S.M.J.Pinent) ( UFRGSAbout UFRGS)  ; Piauí State, Teresina , 1 female from Caesalpinia pulcherrima  , 6.i.2012 (E.F.B.Lima) ( UFPI)  .

Comments. This new species is similar to N. luculentus  and N. zucchi  , but has shorter sense cones in antennal segments III and IV. It seems to be associated to Vachellia caven  flowers [ Fabaceae  ] in southern Brazil, although one specimen was collected from another Fabaceae  in the northeast.
