Abdomen. Tergites and sternites light brown. Terminalia (Figs. 8, 10, 12). Hypandrium not observed. Pre- and postgonites connected, aligned; postgonite elongated, acute distally, with one bristle and sensorial pores; pregonite long, thin; basiphallus rounded; phallapodeme short. Epandrium rounded; surstylus truncated, apically divided in two, pilose, with some bristles and a row of spines at apex; proctiger moderately developed, flap-shaped; mesolobus trapezoidal, slightly bilobed apically. Female. Unknown. Etymology. The specific epithet of this species refers to the type ���locality, the railroad station Eugenio Lefevre, inaugurated in 1916. It was named after the engineer who projected the railroad reaching that spot at the altitude of almost 1,200 m above sea level in the Serra da Mantiqueira. Comments. The male genitalia of the holotype had already been prepared when the specimen was examined. The genitalia was in the vial, but the hypandrium was unfortunately not in the vial. Campos do Jord��o, in the State of S��o Paulo, the type-locality of the species, is more to the north than the known distribution of I. trilineatus. Nevertheless, it is an area of considerable altitude and with occurrence of Araucaria, indicating that the genus may be restricted to southern parts of the Atlantic Forest. Both species of Ischnochlorops have the scutum considerably flattened and covered with delicate, scattered scutal setation. The notopleurals are also delicate and it is hard to discern between scutal setae and the notopleurals. Key to the species of Ischnochlorops 1.

General color yellow, slightly wider than thorax, longer than broad in dorsal view, almost twice as long as high in lateral view; frontal triangle brown, margins convex at apical third, reaching anterior margin of frons; occiput dark, bare; gena yellow, about 0.2 eye height, postgena short; eye oval, bare, long axis horizontal; facial carina incomplete, present only on dorsal fourth; clypeus indistinct, with two brownish spots; labella reduced, yellow; palpus short, clavate, yellow.

Epandrium trapezoidal; surstylus truncate, pilose; proctiger well developed, flap-shaped; mesolobus almost square, slightly bilobed apically. Female. Unknown. Comments. The holotype of I. trilineatus is referred to be deposited in the Canadian National Collection in Ottawa (Paganelli 2002: 38). Unfortunately the specimen was never sent to the depositary collection (Paganelli, pers. com.) and could not be found at the MZUSP collection. The paratype, from Umuarama, state of Paran��, was found and examined. The phallapodemic sclerite could not be observed in the paratype, though the original description (Paganelli 2002, Fig. 114) states that this structure is present, similarly to the structure seen in I. lefevrei sp. nov. The occurrence of I. trilineatus in the west of the State of Paran�� is not surprising. In both areas we find Atlantic Forest with Araucaria angustifolia (Bertoloni) Otto Kuntze (Conifera, Araucariaceae), which has typically more temperate elements of the Diptera fauna (see, e.g., Oliveira & Amorim 2010 a,b)., Published as part of Raile, Riccardi Paula & Souza, Amorim Dalton De, 2013, The Neotropical chloropine genus Ischnochlorops Paganelli 2002 (Diptera: Chloropidae), with the description of a new species, pp. 289-294 in Zootaxa 3750 (3) on pages 290-292, DOI: 10.11646/zootaxa.3750.3.8, http://zenodo.org/record/219744
