Neohydatothrips clavisetis sp. n.

( Figs 19 , 48 , 69, 78 )

Female macroptera. Colour: body dark brown, yellowish only on tergite X, lateral areas of VI (cf. Fig. 78 ), and anterior margin of pronotum; fore wing dark with pale sub-basal band and diffusely paler median area, clavus with stout black setae; antennal segment I light brown, II pale, III pale medially but base and apex light brown, IV basal half pale apical half brown, V–VIII brown; femora dark brown, tibiae and tarsi yellowish; major setae on wings and pronotum stout and black.

Structure: Occipital apodeme confluent with posterior margin of eyes, ocellar area striate; antennal segments III & IV slender with apex not constricted to a neck; pronotum transversely striate, blotch well-defined with anteromarginal setae irregularly arranged, posteroangular paired setae long and dark ( Fig. 19 ); mesonotum and anterior part of metanotum closely striate; metasternal plate with shallow anterior emargination; fore wing second vein with no setae ( Fig. 48 ); clavus with 4 long veinal setae and one long discal seta ( Fig. 69 ); tergites II–VI with comb of microtrichia absent medially, VI with minute teeth, VII–VIII with comb of long microtrichia; tergite IX with 2 pairs of mid-dorsal setae; sternites apparently with discal microtrichia medially.

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; clavus setae 75. Antennal segments I–VIII length 17, 30, 49, 46, 36, 36, 10, 9.

Material studied. Holotype female, BRAZIL, Santa Catarina State, Nova Teutônia [Seara], on Solanum , 25.v.1949 (JDH 2044) ( USNM).

Paratype female, BRAZIL, São Paulo State, São Carlos , on vine, 15.vi.1948 (JDH 1633) ( USNM).

Comments. This is one of the darkest species of Neohydatothrips in South America and, although known only from 2 females collected by Fritz Plaumann in the 1940’s, it is remarkable for the unusually stout black setae on the fore wing clavus and the slender antennae.
