Holopothrips pictus Hood

( Figs 218–220 )

Holopothrips pictus Hood, 1942: 584 .

Diagnostic features. Body (except antenna) mostly brown, with abdominal segments II–III yellow; head with postocular setae well-developed, with capitate apex; maxillary stylets parallel; one pair of long setae on epimeral region; metanotal sculpture formed by longitudinally elongate reticles, bearing internal markings; pelta with reticulation bearing internal markings; males with pore plates on sternites VI–VIII; female spermatheca enlarged medially.

Comments. Originally described from Southeastern Brazil, this is one of four species of Holopothrips with mostly brown body but a few abdominal segments pale. In H. pictus only segments II–III are yellow ( Fig. 220 ), and the hind femora are uniformly brown. This species is similar to H. balteatus , being distinguished only by having the postocellar setae shorter than the diameter of an ocellus, having metanotal reticles more elongate and the third abdominal segment yellow. A series of two males and five females, collected from Southern Brazil together with the type series of H. punctatus sp. n., are very similar to H. pictus and believed to belong to this species; these two males have pore plates on sternite V besides VI–VIII.

Material studied. 1 female non-type; Brazil, Santa Catarina, Seara, Nova Teutônia , 300–500 m, on litter, vii.1957 (Plaumann, F.), at BMNH.
