Holopothrips permagnus Hood

( Figs 212–217 )

Holopothrips permagnus Hood, 1938: 236 .

Diagnostic features. Body (except antenna) uniformly brown; head much longer than wide, about 400 µm long, maxillary stylets parallel; one pair of long setae on epimeral region; mesonotal sculpture with internal markings; metanotal sculpture striate anteriorly and with elongate reticles posteriorly, with internal markings; pelta with lateral wings basally, reticulation without internal markings; males with pore plates on sternites VII–VIII, two anteroangular plates and a transverse posterior band on VIII; female spermatheca not enlarged.

Comments. Described from Peru, collected from an unidentified plant. Holopothrips permagnus is one of the largest species of the genus, characterized by its dark brown colour, including all tibiae, very long head (observed specimen with head over 1.8 times longer than wide—Fig. 212). Pronotal am and aa setae are very reduced, while ml is long and dislocated closer to the anterior margin of pronotum ( Fig. 214 ). This species is comparable to other species with elongate head, such as H. claritibialis , H. hambletoni (whose metanotal reticulation is equiangular and lack internal markings), H. inversus (a much smaller species), H. orites (whose metanotal sculpture is finely striate thoroughly) and H. oaxacensis (which was recorded only from Mexico).

Material studied. 1 female paratype; Peru, Cajamarca, vicinity of Celendin , 1–3.vi.1936 (Woytkowski, F.), at NMNH. Slide with code “ Hood No. 1187”.
