Neohydatothrips inversus (Hood) 

( Figs 28View FIGURES 24 – 31, 59, 61, 62View FIGURES 50 – 66, 77View FIGURES 67 – 79, 98, 99View FIGURES 92 – 103)

Sericothrips inversus Hood, 1928: 232  . Sericothrips geminus Hood, 1935: 146  .

Female macroptera. Colour: body yellow with light brown markings ( Fig. 98View FIGURES 92 – 103), pronotum with three pairs of light brown areas laterally that are not fused medially; mesonotum yellow, metanotum light brown; tergites II–VII with antecostal ridge brown and paired brown markings anterolaterally, VIII–X yellow; fore wing pale with faintly shaded area in basal third, clavus weakly shaded; antennal segment I pale, II with light brown markings, III pale at base, IV brown medially with apex sharply pale; hind tibiae yellow, femora lightly shaded.

Structure: Occipital apodeme not confluent with posterior margin of eyes; mouth cone long, extending between fore coxae; antennal segments III & IV with apex constricted into neck; pronotum transversely striate ( Fig. 28View FIGURES 24 – 31); mesonotum with four setae in transverse row, metanotum weakly reticulate; metasternal plate weakly developed, anterior margin almost transverse ( Fig. 59View FIGURES 50 – 66); fore wing second vein with no setae; tergites VII–VIII with complete comb of long microtrichia on posterior margin, no comb medially on remaining tergites; tergite IX with 4 pairs of mid-dorsal setae ( Fig. 77View FIGURES 67 – 79); sternites III–VII without discal microtrichia medially.

Male macroptera. Similar to female but smaller ( Fig. 99View FIGURES 92 – 103), sternites IV–VII with oval pore plate 25 microns wide ( Mound & Marullo 1996).

Material Studied. Holotype female of inversus  , DOMINICA, 13.iii.1915 ( USNMAbout USNM)  . Holotype female of geminus  , PANAMA, Barro Colorado Is., 9.viii.1933 ( USNMAbout USNM)  . BRAZIL, Piauí State, Bom Jesus , 3 females from weeds, 30.vii.2012 (E.F.B.Lima) ( UFPI)  . TRINIDAD, Curepe , 1 female from Coursetia arborea  leaves, 9.xi.1970 (L.A.Mound)  . MEXICO, Oaxaca State, La Ventosa , 1 female from? Citrus  , 29.iii.2014 (F. Infante) ( ANICAbout ANIC)  .

Comments. Described originally from Dominica and Trinidad, this species was recorded subsequently from Panama. Mound and Marullo (1996) synonymised geminus  with N. inversus  , these two having a very similar mesonotum and metanotum. We examined the type material of both species, and the types of geminus  differ from those of inversus  in having the sense cones on segment IV distinctly longer ( Figs 61, 62View FIGURES 50 – 66), also the anterior margin of the pronotal blotch completely coloured, with the pronotal discal setae in a transverse row. Nevertheless, in material from Brazil and Central America these character states are not constant, with specimens variably bearing morphological traits of both nominal species. Therefore, geminus  remains treated here as synonym of N. inversus  .
