Prosaspicera uniformis Ros-Farré n. sp.

( Figs 27b & 28b)

Type material (1 ♂ & 2 ♀). HOLOTYPE: female ( NHMLAC), II-1987, Madre de Dios, Reserva de Tambopata ( PERU) D.W. Davidosn col. PARATYPES (1 ♂ & 1 ♀): BRAZIL: 1 ♂ ( USNM), VI-1961, Sta. Catarina, Florianapolis, Krauss col.; 1 ♀ ( NHM), nº 520 III- 1962, Sao Paulo, Ex. puparium of Syrphid. C.I.E. col.

Diagnosis. Prosaspicera uniformis is similar to P. dentata since they both have a very effaced median ridge, the anteroadmedian lines very short and confluent, and the scutellar spine long and thick. Nevertheless, P. dentata has a tooth in the mesoscutum ( Fig. 28a), absent in P. uniformis ( Fig. 28b). Moreover, in P. uniformis the frons is coriaceous with strong frontal carinae, vertex very incised, ocelli strongly prominent; mesoscutum coriaceous, notauli very wide and smooth; parascutal sulcus quite wide and ending in front of tegula. Marginal pubescence of wing absent.

Description. Length. Females and males: 2.5 mm.

Coloration. Head and mesosoma black except for scutellum, posterior part of mesopleurae and metapleurae dark. Metanotum dark to black. Scape and pedicellum brown, flagellomeres lighter brown. Legs light brown with exception of last tibia and trocanter, which are darker.

Head. Frons weakly coriaceous with frontal carinae. Lateral frontal carinae conspicuous area between them and eye coriaceous. Occipital carina sharply angled behind dorsal 1/3 of eye. Gena glabrous, expanded, coriaceous, almost smooth near occipital carina and with transverse carinae on ventral half. Vertex very incised, shining and weakly coriaceous, in posterior part smooth with one longitudinal carina on each side of median vertical groove, which is smooth. Ocelli strongly prominent. Occiput smooth, delimited with one strong transverse carina.

Antenna. FEMALE. Filiform. Antennal formula: 5(3.5): 2(2.2): 7(2): 5.9(2): 5.1(2): 5.1(2): 5(2): 4.5(2): 4(2): 4(2): 3.8(2): 3.5(2): 7.8(2). MALE. Filiform. Antennal formula: 4(2.6): 1.8(2): 6(1.9): 5(1.5): 5(1.5): 5(1.5): 4.5(1.5): 4(1.8): 4(1.8): 4(1.8): 4(1.8): 3.2(1.8): 3.1(1.8): 6(1.8).

Mesosoma. Lateral surface of pronotum coriaceous, sparsely pubescent. Subpronotal plate weakly coriaceous and glabrous. Mesoscutum with scattered setae, coriaceous. Antero-admedian lines prominent, reaching between 1/5 and 1/4 the length of the scutum 1/4 and 1/ 3 in male and strongly confluent. Median ridge only present near anterior margin of mesoscutum. Notauli very wide, smooth. Median mesoscutal furrow smooth. Area between notauli and end of median mesoscutal furrow strongly prominent. Parascutal sulcus quite wide smooth and glabrous, effaced from tegulae to anterior end of notauli. Mesopleura slightly alutaceous in anterior 1/5, smooth in posterior part, entirely smooth in male. Scutellum 2.41 to 2.60 times length of scutum. Scutellar foveae trapeze-shaped or longitudinally oval, deep, smooth and shining, with weak posterior margin; interfoveal line and lateral carinae continuing to last 1/3 of spine. Scutellar disc weakly coriaceous. Scutellar spine weakly striate, in lateral view, at same plane as scutellar foveae straight to last 1/3, downwards directed and curved in the posterior 1/3; almost reaching end of radial cell of wing.

Wings. Wing membrane hyaline or yellowish. Radial cell 2.08 to 2.50 times longer than wide. Marginal pubescence absent. R1 short to rather long, Rs straight.

Derivatio nominis: Refers to the extremely weak sculpture this species has on the head and mesosoma.

Biology. Obtained from puparium of a syrphid (species unknown), according to specimen references.

Distribution. Neotropical. Known only from Peru and Brazil.
