Neohydatothrips humberto Mound & Marullo, 1996: 169 .

Female macroptera. Colour: brown, except for tibiae and fore wing sub-basal pale band and apex; antennal segments I–II yellow, III light brown, IV–VIII brown.

Structure: Occipital apodeme not confluent with posterior margin of eyes, ocellar area weakly reticulate with faint markings between the striae (Fig. 22); pronotum transversely reticulate with internal markings, pronotal blotch distinct; mesonotum transversely striate; metanotum with striae transverse on anterior half and longitudinal on posterior half; metasternal plate with shallow emargination (Fig. 57); fore wing second vein with one seta; comb of microtrichia with sparse minute teeth on tergites II–VI, medium-sized teeth on VII and complete on VIII; tergite IX with 2 pairs of mid-dorsal setae; sternites II–VI with microtrichia medially, VII with microtrichia medially.

Material studied. Paratype female, COSTA RICA, Poas Volcano, on grasses by road, 30.vi.1983 (BMNH) . GUATEMALA, Solola, 3 females on Phaseolus vulgaris, 21.iii.1997 (ANIC) .

Comments. This species was described based on 5 females from Costa Rica . It is very similar to other dark brown species such as N. mirandai and N. lassatus . It is particularly similar to N. tibialis, from which it is tentatively distinguished based on the characters in the key. These two possibly represent the same species, but the poorly mounted type specimens of N. tibialis do not permit firm conclusions on their identities. Previously known only from Costa Rica, 3 females have been identified from Guatemala .
