( Figs 53–54 )

Holopothrips chaconi Zamora, Hanson & Mound, 2015: 1038 .

Diagnostic features. Body (except antenna) uniformly brown; maxillary stylets parallel; pronotal am and aa setae very small, two pairs of long setae on epimeral region; metanotal sculpture formed by slightly elongate reticles, some with faint internal markings; pelta apparently without campaniform sensilla, or with short stout setae instead of sensilla; males with pore plates on sternites VII–VIII; female spermatheca enlarged medially.

Comments. This light brown species was recently described from Costa Rica, breeding in abandoned cecidomyiid galls in Piper spp. leaves. Males have irregular transverse pore plates on sternites VII–VIII, usually complete medially on VIII but broader laterally, always interrupted medially on VII. Larvae are pale yellow and lack red internal pigmentation.

Material studied. Paratypes: 1 male, Costa Rica , San José Province, Zurquí de Moravia , in Piper bredenmey gall, 8.xi.2013 (Zamora, S.) ; 1 female, same locality, in Piper lanosibrae gall, 7.viii.2013 (Zamora, S.); both at BMNH .
