Small to medium-sized insects, 1 to 6 mm., body color black, ferrugineus, fuscous, brownish, or yellowish, smooth and polished, without sculptures. Antenna of female usually 13-segmented, terminal segments in most cases forming a club. Antenna of male usually 15-segmented, filiform. Scutellar cup elevated, of various sizes and shapes. Pronotum touching tegula (fig. 1). Fore wing without true stigma; radial cell either open or closed on frontal margin. Abdomen laterally compressed with ovipositor ventrad at apex.

In the classification of the subfamily, the number of antennal club segments in the female is used to separate the different subgenera. The males cannot be assigned to subgenera unless they are reared and associated with the females. The outstanding morphological character of Eucoilinae is the elevated scutellar “cup” (see fig. 2, d). The “cup” varies in characters and is of aid in separating genera and species. The Micronesian species have the wing surface pubescent and wing margin ciliate. The body length as given in this paper is measured at the side from the anterior end of the head capsule to the tip of the abdomen.
