- Pteromalidae: The pteromalids are minute, metallic-bronze
insects with greatly reduced wing venation and triangular-shaped abdomens.
- Dinotiscus dendroctoni (Ashmead) (figs. 57, male; 58, female;
59A): The sexes of D. dendroctoni differ markedly. Both sexes
are metallic green-black with clear wings having greatly reduced venation.
Also, the thorax is densely punctate. Females (3.8 mm) have long, pointed
abdomens. Males (2.7 mm) appear similar to males of Roptrocerus
(fig. 59), but have a distinctly rectangular stigma in the forewing
(fig. 59A).

- Roptrocerus Ratzeburg (figs. 59B, 60, male; 61, female):
Both sexes of Roptrocerus have a finely punctate thorax. They
are usually smaller than D. dendroctoni; females are 3.0 mm,
males 1.8 mm long. Males and females have a rounded stigma in the forewing
(fig. 59B). Their wings have short hairs.
- Heydenia unica Cook and Davis (fig. 62): H. unica
adults (2.84.2 mm) are usually reddish brown and have large front femora.
There is a spot on the forewing. The pronotum is bellshaped, and gives
it a "necklike" appearance.
