Abstract

The genus Rhagosmittia gen. n. is described based on Spaniotoma (Smittia) maculiventris Edwards, originally collected and described from the Marquesas Islands in French Polynesia. The genus differs from all other chironomids by having a fissured tergite IX, with spatulate median acrostichals and clypeus with long and dense microtrichia. The genus apparently belongs in the Pseudosmittia complex of genera. Rhagosmittia maculiventris (Edwards) comb. n. is redescribed. The genus Trondia gen. n. with the single included species Trondia anderseni is described based on a specimen from Western Australia. The genus combines features found in Ionthosmittia Andersen et Sæther with characters found in Pseudosmittia Edwards.
