Holopothrips erianthi (Hood)

( Figs 66–68 )

Homorothrips erianthi Hood, 1954: 52 .

Diagnostic features. Body (except antenna) uniformly brown; head slightly longer than wide, maxillary stylets parallel, retracted to posterior margin of eyes; one pair of long setae on epimeral region; mesonotal sculpture without internal markings; metanotal sculpture striate thoroughly; pelta with irregular reticles covering the whole structure, without internal markings; males with two anteroangular pore plates on sternites VI–VIII, and a widely interrupted posterior transverse plate on VIII.

Comments. Originally described in the monotypic genus Homorothrips , based on individuals collected from a species of grass in Southeastern Brazil. In the UFRGS collection there are several specimens from different areas of Brazil, from a variety of plants (including Myrcia splendens , the apparent host plant of H. conducans galls), which are believed to belong to this species. No type specimens could be observed in this work.

Material studied: 2 non-type specimens; Brazil, Minas Gerais (?), in Lithraea brasiliensis , at ANIC. Slide with code “9Mg57-2”.
