( Figs 37 , 52 , 106 )

Hydatothrips (Neohydatothrips) samayunkur Kudo, 1995: 169 .

Female macroptera. Colour: body bicoloured ( Fig. 106 ), head brown, pronotum with anterior area yellow but blotch brown, mesonotum and metanotum brown, tergites I–II light brown, III–VI brown laterally but increasingly yellow medially with antecostal ridge dark brown, VII–IX dark brown, X brown; fore wing with 3 dark and 3 pale bands, apex pale, clavus dark with brown setae; antennal segment I pale, II with brown shadings, III pale with brown base and apex, IV–V pale with apex brown; hind tibiae yellow with external margin shaded, femora brown. Structure: Occipital apodeme well separated from posterior margin of eyes, ocellar area with reticulate markings ( Fig. 37 ); antennal segments III & IV constricted to short apical neck; pronotum anterior area with transverse reticulation but no internal markings, blotch striate and bearing transverse row of setae ( Fig. 52 ); mesonotum and metanotum striate ( Fig. 52 ); metasternal plate with shallow emargination; fore wing second vein with no setae distally; tergite VIII with complete comb of microtrichia on posterior margin, VII with comb interrupted medially, no comb on remaining tergites; tergite IX with 2 pairs of mid-dorsal setae; sternites III–VI with microtrichia, VII without microtrichia medially.

Male macroptera. Similar to female but smaller, tergites II–VII and X yellow; sternite VII with small circular pore plate.

Larva II. Pale with microtrichia on dorsal surface. Antennae 7-segmented, segment I yellow, II–VII yellowish brown. Thorax with brown sclerotized areas on mesonotum and metanotum. Body with several brown setae with fringed, expanded apices, about 10 microns long medially and 20 microns laterally on thorax and abdominal tergites I–IV; sternal setae acute.

Material Studied. BRAZIL, Paraná State, Curitiba , 18 females flowers of Tagetes patula , 30.i.2015 (A.S.

Poltronieri & E.F.B. Lima) (UFPI). Several specimens from MEXICO, SOUTH AFRICA, KENYA, MAURITIUS and EASTERN AUSTRALIA ( ANIC) .

Comments. This species has been recorded from several countries around the world as a pest of garden Tagetes plants. It was misidentified by Mound and Marullo (1996) and Mound et al. (1996) under the name N. pseudoannulipes Johansen , based on a specimen purporting to be a paratype of this species on loan from Roberto Johansen. Nakahara (1999) subsequently recognized this specimen as N. samayunkur , and this pest of marigold plants ( Tagetes spp.) has also been found in southern Brazil ( Monteiro et al. 1999).
