Hydatothrips canavaliae sp. n.

( Figs 3 , 9–11 )

Female macroptera. Colour: body yellow, with brown on ocellar area, pronotal blotch, lateral thirds of metanotum, antecostal ridges, and anterolateral areas of abdominal tergites II–VII; fore wing yellowish brown, with paler subbasal area; legs yellow with femora shaded brown; antennal segments I–II yellow, III brownish yellow, IV with basal half yellowish brown and apical half brown; V with basal tip yellowish brown and the rest brown, VI–VIII brown.

Structure: Occipital apodeme not touching posterior margin of eyes, ocellar area reticulate, ocellar setae pair III on external margins of ocellar triangle, three pairs of postocular setae ( Fig. 3 ). Pronotum broadly reticulate, blotch well-defined, blotch reticles with weak internal markings ( Fig. 3 ); mesonotum reticulate with median setae far ahead of lateral setae; metanotum reticulate with two pairs of setae on anterior margin ( Fig. 9 ). Metasternal plate with anterior margin deeply emarginated ( Fig. 10 ). Fore wing second vein with no setae. Tergites I–VIII with closely spaced rows of fine microtrichia on lateral thirds, posterior margin of tergites II–V with comb of microtrichia incomplete medially, VI with minute microtrichia medially, comb complete on VII–VIII; tergite IX with 4 pairs of mid-dorsal setae. Sternites with discal microtrichia not extending mesad of setae S2, posteromarginal comb present lateral to setae S2.

Larva II. Clear with dark markings all over the body; abdominal segments IX and X brown. Antennae 7- segmented, segment I yellow with brown shadings, II brown, III–IV yellow, V–VI brown. Thorax with brown sclerotized areas. Body with several brown setae ( Fig. 11 ), with broadly expanded and fringed apices (apex about 4 times as long as base) arising from well-developed brown rings.

Measurements (holotype female in microns): Body length 980, Head, length 58, width 150; ocellar setae III length 10. Pronotum length 165, width 178. Fore wing length 650. Antennal segments I–VIII length 17, 30, 49, 46, 36, 36, 10, 9.

Material studied. Holotype female, BRAZIL, Piauí State, Teresina , on Canavalia brasiliensis , 7.vii.2010 (E.F.B.Lima) ( ESALQ).

Paratypes: from same locality and host as holotype, 3 females, 9.vii.2010 ; 8 females and 4 larvae, 17.vii.2011 (E.F.B.Lima) (UFPI, UFRGS, USNM, CAS and ANIC).

Comments. Named after its host plant on which larvae and females have been collected commonly, this new species is unique in having pronotum, mesonotum and metanotum boldly reticulate. Males were not collected.
