Mandibular formula 3:3. Clypeus sometimes faintly outlined by sutures, usually
not discernable. Transverse frontal groove V-shaped; scrobal grooves reaching transverse
groove separately, usually extending below toruli ventrally; interscrobal process reaching
transverse groove. Vertex sometimes carinate. Flagellum 6-segmented, including 1 anellus.
Pronotal collar sometimes carinate; mesoscutal midlobe with 2 pairs of setae; anterior
portion of notauli curving sharply laterad; upper mesepisternum without an extension
overlapping posterior edge of prepectus; no pit between axilla and scutellum. Postmarginal
vein length variable: from shorter than stigmal vein to over 2x its length. Propodeum
with modified median carina: either broadened and dorsally flattened, or
split posteriorly; plicae sometimes present. Petiole transverse or longer than
broad, sometimes sculpted, sometimes with a dorsal flange. Compare with: Chrysocharis
(Zaommomyia), Pediobius, Closterocerus,
Proacrias face (left), and gaster of female (right)
coffeae has been reared from coffee leafminer, Leucoptera coffeella
(Guérin-Méneville & Perrottet), Lyonetiidae. Other species have been reared from
agromyzid leaf miners.
Comments: A poorly
defined genus which may be misinterpreted because the type specimens of the type species, Proacrias
coffeae Ihering, have been missing since at least 1969. Under the current
interpretation, Proacrias is very similar to some Chrysocharis (Zaommomyia),
to the point that I cannot confidently place some species to genus. It is also very
similar to Pediobius and Closterocerus, from which it differs only in
characters that are usually not used to define genera. I suspect that this Proacrias is
closely related to Closterocerus, but not to Pediobius. This genus is
chiefly Neotropical, but I have found it from Nearctic Mexico (Jalisco).
(Zaommomyia): Median carina of propodeum not broadened or
First gastral tergite well-sclerotized and dorsal surface not collapsing or capable of
changing shape when drying, the other tergites tending to telescope inside the first
tergite in air-dried specimens; as opposed to the condition in Proacrias and
similar genera (such as Closterocerus), where the gaster is dorsally collapsed in
air-dried specimens and the first tergite does not hold a consistent shape. Upper
mesepisternum with an extension that can usually be seen to overlap the posterior margin
of the prepectus. First gastral sternite with a strongly sclerotized, densely punctulate
region below the petiolar base.
Closterocerus: Median carina of propodeum
not broadened or posteriorly split.
Chrysocharis s.s.: Scrobal
grooves uniting before reaching transverse frontal groove.
Ionympha: Mandbiles elongate and with many
small denticles. Gena with an incision for reception of mandibles. Ovipositor extremely
