Holopothrips inversus Hood

( Figs 125–130 )

Holopothrips inversus Hood, 1955: 146 .

Diagnostic features. Body (except antenna) uniformly brown; maxillary stylets parallel; one pair of long setae on epimeral region; basantra weakly developed; metanotal sculpture formed by elongate reticles, looking almost striate anteriorly, and few equiangular reticles posteriorly, with internal markings; pelta with anterior margin forming a pointed tip, sculpture with few thin reticles medially, weaker or absent near lateral and anterior margins; males with three broad pore plates on sternites VII–VIII, the posterior plate on VIII extending towards tergite.

Comments. This is yet another Holopothrips species described from Southeastern Brazil, without the identification of its host plant. It has an unusually long head, about 1.6 times longer than wide ( Fig. 125 ). Mesonotum bears internal markings in the lateral reticles ( Fig. 127 ); the metanotal sculpture is formed by very elongate reticles with internal markings anteriorly, almost forming a striate pattern, which becomes almost equiangular posteriorly ( Fig. 128 ). This species is comparable to some other Holopothrips with elongate heads, such as H. claritibialis , H. hambletoni (whose metanotal sculpture is mostly equiangular) H. orites , H. permagnus (species with much larger bodies) or H. oaxacensis (which has minute am setae and maxillary stylets closer together in the head).

Material studied. 1 male paratype; Brazil, São Paulo, Itanhaém , 17.vi.1948 (Hood, J.D. and Lane, J.), at BMNH. Slide with code “ Hood No. 1637”.
