A new species of the genus Chiromyza Wiedemann (Diptera, Stratiomyidae) from Rio de Janeiro, Brazil

Seven species of the genus Chiromyza Wiedemann are recorded in Brazil: C. brevicornis (Lindner, 1949), C. enderleini (Lindner, 1949), C. leptiformis (Macquart, 1838), C. ochracea Wiedemann, 1820, C. stylicornis (Enderlein, 1921), C. viridis Bezzi, 1922 and C. vittata Wiedemann, 1820. Herein I describe a new species, Chiromyza raccai sp. nov., based on 88 specimens (41 males, 47 females) from the Atlantic Rain Forest mountains of State of Rio de Janeiro, Brazil, in the city of Miguel Pereira. The new species is distinguished from the related species C. ochracea and C. vittata by the structure of male terminalia. Chiromyza raccai sp. nov. has the distal region of the phallus rounded with two conspicuous apical setae, C. ochracea has the distal surface of the phallus wide and flatness, and C. vittata has the distal surface of the phallus rounded with outer margin rugose.

Description of the puparium of Manotes plana (Diptera: Stratiomyidae: Pachygastrinae) from the Ilha da Marambaia, Mangaratiba, state of Rio de Janeiro, Brazil

The puparium of Manotes plana Kertész, 1916 is described based on the exuviae of six larvae collected under the bark of a plant in early state of decomposition in the Ilha da Marambaia (23°04'15"S, 43°53'59", at sea level), state of Rio de Janeiro, Brazil. The external morphology and chaetotaxy is compared with the previously described puparium of Manotes crassimanus James, 1980. The texture and shape of the setae of M. crassimanus are plumose and some setae are claviform while M. plana are setiform. In M. plana the ventro-craneal furrow extends from the posterior region of the mouthparts until the median region of the head. In M. crassimanus, the furrow extends until the posterior third of the head. No diferrence occurs in position in the puparia of both species in relation of pupal respiratory spiracles.
