Fine structure of the eggs of blowflies Aldrichina grahami and Chrysomya pacifica (Diptera: Calliphoridae)

We report here the fine structure of the eggs of blowflies Aldrichina grahami (Aldrich) and Chrysomya pacifica Kurahashi. For A. grahami, the plastron is wide and extends to almost the entire length of the eggs. The plastron near the micropyle is truncated. The polygonal patterns of chorionic sculpture bear a distinct swollen boundary. Regarding C. pacifica, the plastron is narrow and extends to almost the entire length of the eggs. The plastron near the micropyle bifurcates to a Y-shape, but the arms of the 'Y' are short. Information presented herein allows some distinctive features to differentiate among eggs of blowfly species.

Two new species of Euphumosia from Papua New Guinea (Diptera: Calliphoridae)

Two new species of the calliphorid blow flies are described from Papua New Guinea under the names of Euphumosia lopesi and E. robertsi. Body coloration and mesonotal pattern are characteristic and differ from those of the closely allied species, E. evittata Togerson & James, 1967.
