Sericothrips maculicollis Hood, 1954: 203.
Female macroptera. Colour: body bicoloured (Fig. 100), head light brown, mesonotal anterior margin and metanotum brown, tergites II–IV brown to light brown, VII–VIII dark brown, IX light brown, X yellow; fore wing with clearly defined sub-basal pale band, but median pale band weakly defined from surrounding brown areas, and small apical pale area weakly defined, clavus dark with brown setae; antennal segment I pale, II–III and base of IV mainly pale but with weak shadings; hind tibiae and femora yellow.
Structure: Occipital apodeme confluent with posterior margin of eyes (Fig. 33), ocellar area transversely striate with internal markings; antennal segments III & IV constricted to short apical neck; pronotum transversely reticulate to striate with a few weak internal markings, blotch with anterior striae more closely spaced, setae placed irregularly (Fig. 33); mesonotum and anterior part of metanotum striate (Fig. 33); metasternal plate with shallow Vshaped emargination; fore wing second vein with one seta distally; wing apex with small subapical lobe; tergites III–V with posteromarginal comb incomplete medially, VI sometimes with minute teeth medially, VII with small teeth medially, VIII with complete comb; tergite IX with 2 pairs of mid-dorsal setae; sternites with one or two rows of discal microtrichia medially.
Male macroptera. Similar to but smaller than female, with light brown tergite V and pale tergite VII (Fig. 101); sternite VII with very small circular pore plate.
Material studied. BRAZIL, Holotype female, São Paulo State, Franco da Rocha, 11.vi.1948 (USNM); Santa Catarina State, Nova Teutônia [Seara], 6 females, 3 males from Alchornea (or Trichilia), 14.xii.1949; 2 females, 1 male from Trichilia sp., xii.1949; 1 female, 2 males from Balfourodendron licanum, 20.xii.1949; 1 female, 1 male from Terminalia, 26.xi.1949; 1 male from Sapium, 1.xii.1949; 4 females, 2 males from dry branches, 1.i.1949 (F. Plaumann) (USNM); Rio Grande do Sul State, Jaquirana, 1 female from Myrcia lajeana, 1 male from Discorea cf. sublastatum, 1 female from Erythroxylum deciduum, 28.i.2013, São Francisco de Paula, 1 female from Lamanonia ternata, 26.i.2013 (A. Cavalleri) (UFRGS). TRINIDAD, St. Joseph, 1 female, 26.vi.1951 (USNM).
Comments. Described from 6 females collected near the city of São Paulo, further specimens examined are listed above, including 1 male recorded for the first time. The striae on the anterior area of the pronotum are more widely spaced in the type series than in any of the other specimens listed, but this is here interpreted as intraspecific variation. The wing colour is variable, with the two pale areas, medially and at apex, being poorly defined, as discussed below under N. paraensis.
