pachymera (Williston), 1900: 224 (Ceratopogon; female; Mexico). Distr.- USA (Texas) to central Argentina (Entre Ríos: Santa Ana, 30°54'18.67''S, 57°56'32.17''W, 6 m. Buenos Aires: San Isidro, 34°27'44.33"S, 58°30'5.48"W; Magdalena, arroyo Zapata, 35°08'29.55''S, 57°26'32.17''W, 32 m).

latifemoris (Ingram & Macfie), 1931: 231 (Johannsenomyia). Type locality: Argentina, Buenos Aires, San Isidro, 34°27'44.33"S, 58°30'5.48"W. HT F (BMNH).
Is fully redescribed for Spinelli et al, 2016, with a modern criterium from material collected in Buenos Aires and Entre Ríos provinces in Argentina, and Uruguay. Exhibit elongated and thin anteromedial sensilla, typical of the Palpomyiini genera. Differences with the known pupae of the American species included in the Palpomyia tibialis group are noted for P. pachymera and differences with the remaining Palpomyiini genera are noted for C. dycei.
The pupae of the predaceous midges, Pachyhelea pachymera(Williston, 1900) and Clastrieromyia dycei Spinelli and Grogan, 1986, are redescribed and illustrated using modern terminology from specimens collected in Buenos Aires and Entre Rıos Provinces, Argentina, and Artigas Department, Uruguay. Both species exhibit elongated, thin anteromedial sensilla that are characteristic of other
genera in the tribe Palpomyiini. Character differences from known pupae of the New World species in the Palpomyia tibialis group are noted for P. pachymera and differences from other Palpomyiini genera are noted for C. dycei.
