P. longicaudatus sp. n. is characterized by 1.78–2.14 mm long female body, lip region slightly set off by adepression, odontostyle 30–32.5 μm long and 2.0–3.5 µm wide; pre-rectum 1.3–2.3 anal body diameters long in female and 2–3.5 in male; paravulval papillae absent; spicules 44.5–62.5 µm long; 11–13 ventral supplements; female tail elongate-filiform,11–16 anal body diameters long; male tail short, 0.8–0.9 cloacal body diameters long, convex conoid, with blunt terminus. P.flagellicaudatus sp. n. is characterized by 1.65–1.73 mm long female body, lip region continuous, odontostyle 19–24 μm longand 2–2.5 µm wide; pre-rectum 1.8–2.6 anal body diameters long in female and 2.4 in male; spicules 45 µm long; 10 ventralsupplements; female tail elongate-filiform, 25–26 anal body diameters long; male tail short, conoid, 0.8 cloacal body diameterslong.

Three New Species

Stomopogon Malloch (Diptera, Muscidae) is a Neotropical genus recorded from Argentina, Bolivia, Brazil, Chile and Peru. In this contribution, the genus is revised, and three new species are described, one from Bolivia (Murillo, La Paz), one from Brazil (Palmas, Paraná) and one from Peru (Wayqecha, Cuzco). The descriptions include color images, illustrations and ultrastructural morphology of the terminalia of the adult. We provide an identification key to the species of Stomopogon and an updated map with species’ distributions. Stomopogon acuta (Malloch, 1934) is proposed as a new junior synonym of S. inculta Stein, 1911.

AbstractThe genus Synosis Townes, 1959 (Hymenoptera: Ichneumonidae: Metopiinae) currently comprises 18 described species. A redescription of the genus is presented and three new species are described and illustrated: S. diaguita new species, S. nigra new species, and S. zezei new species. Two previously known species, Synosis rubinus Alvarado and Rodriguez-Berrios, 2013 and S. townesi Alvarado and Rodriguez-Berrios, 2013 are recorded for the first time in Ecuador. The genus is recorded for the first time for Ecuador and Argentina. An identification key to the New World species is presented.

A taxonomic revision of the species-group related to M. filiformis (Saussure 1854) is presented along with an identification key to species. After Richards (1978) and following the rearrangement of the subgenus Omega de Saussure by Silveira (2008), the species-group considered herein included three species in addition to M. filiformis; i.e. M. buyssoni (Ducke 1906), M. napoensis Richards 1978 and M. omicron Richards 1978.  In the present work, three new species are added: M. nazgul sp. nov.; M. asahi sp. nov.; M. kallindusfloren sp. nov.; the male of M. filiformis is also described here in detail for the first time, and new distributional records are provided for the included species.
