Neohydatothrips plaumanni sp. n.

( Figs 35 , 66 )

Female macroptera. Colour: body brownish yellow, postoccipital region of head light brown, pronotum with three light brown areas laterally that fuse medially in some specimens; tergites II–VI with antecostal ridge dark brown and associated light brown areas anterolaterally, VIII–IX with shaded area medially; fore wing uniformly pale brownish grey; antennal segment I pale, II–IV light brown; hind femora and tibiae yellow with light brown markings.

Structure: Occipital apodeme distant from posterior margin of eyes ( Fig. 35 ); ocellar area with sculpture lines weak or apparently absent, setal pair III on or near anterior margins of ocellar triangle; antennal segments III & IV with short constricted neck apically ( Fig. 66 ); pronotum striate, blotch indistinct with irregular transverse row of setae ( Fig. 35 ); mesonotum striate with median setae almost in a transverse row; metanotum with irregular longitudinal striae; metasternal plate with anterior margin almost straight; fore wing second vein with 2 setae distally; tergites II–VI with comb of microtrichia incomplete medially, VII–VIII with comb of long microtrichia; tergite IX with 2 pairs of mid-dorsal setae; sternites without discal microtrichia medially.

Measurements (holotype female in microns): Body length 1139, Head, length 85, width 130; ocellar setae III length 28. Pronotum length 116, width 170. Fore wing length 700. Antennal segments I–VIII length 20, 33, 53, 45, 38, 45, 8, 10.

Male macroptera. Male similar to female; sternites without pore plates.

Measurements (paratype male in microns): Body length 920, Head length 78, width 143; ocellar setae III length 28. Pronotum length 100, width 145. Fore wing length 580. Antennal segments I–VIII length 20, 30, 48, 38, 33, 40, 8, 10.

Material studied. Holotype female, BRAZIL, Santa Catarina State, Nova Teutônia [Seara], 20.xii.1949, on Balfourodendron licanum , (JDH 2082) (F. Plaumann) ( USNM).

Paratypes: 9 females and 9 males collected with holotype; 1 female from same locality as holotype and without host data, 15.xi.1949 (JDH 2017A) ; 1 female from same locality as holotype and without host data, 20.v.1949 (JDH 2041) ; 1 female from same locality as holotype and without host data, 17.xi.1949 (F. Plaumann) ( USNM).

Comments. This species is one of the few members of this genus with the median pair of setae on the mesonotum almost in line transversely with the lateral pair.
