ABSTRACT
The genus Hoplonannus McAtee Malloch, 1925 is composed of H. brunneus, H. paenebrunneus, H. craneae, and H. australis, all previously recorded from Central and South America. In this paper, we describe Hoplonannus bifidus sp.n. and Hoplonannus robustus sp.n. based on several specimens collected in the Brazilian Amazon, representing the first record of the genus from northern Brazil. We provide diagnoses, photographs of habitus, scanning electron micrographs of male genitalia, and illustrations of female genitalia. A key to species based on males of Hoplonannus is also presented.

The genus Hypsohapsis Hoey-Chamberlain Weirauch was erected based on only one male specimen from southern Brazil (São Paulo). Hypsohapsis amazonica sp.n., described herein from the Brazilian Amazon, is based on a male and two females collected in pristine tropical forest. The female of Hypsohapsis is described for the first time. In addition, an updated key to the genera of Hypselosomatinae is provided.

The genus Plagaedessa gen. n. is proposed to accommodate four species: Edessa celsa Distant and three new species: P. distanti sp. n., P. nigrovittata sp. n. and P. maranhensis sp. n. The new genus is characterized by the antennae black with the antennomer I showing a yellow spot on ventral surface, legs yellow with femora and tibiae showing two or three longitudinal black stripes, gonapophysis 9 with a sclerotized area bearing a protuberance close to gonocoxites 9 and pygophore with black posterolateral angles strongly developed. Diagnosis, illustrations of the metasternal process and external and internal genitalia, photographs of the dorsal and ventral view, and a distribution map are provided. A key to the genera of Edessinae and subgenera of Edessa, and a key to the species of Plagaedessa are also provided. Male and female genitalia of Plagaedessa celsa n. comb. are described for the first time. Distribution of P. celsa is extended to Costa Rica and Mexico. The lectotype of Edessa celsa is here designated.

The nomen nudum Liriomyza flagellae is formerly described in this paper as Liriomyza valladaresae sp. nov., based on male and female specimens collected in the Brazilian Amazon and reared from leaves of Alternanthera tenella and Amaranthus viridis (Amaranthaceae). Information on the puparium and the biology of this new species are provided. The species Liriomyza blechi, previously recorded from the U.S.A., Guadeloupe and Dominican Republic, is newly recorded from Brazil, reared from leaves of Blechum pyramidatum (Acanthaceae) and Spigelia anthelmia (Loganiaceae).
