(Tribe Smiliini)
Overview • Description • Distribution • Taxonomy
Description |
Females are usually less than 5⁄16″ (8 mm) in length, but there are several exceptions. The upper margin of the head is straight or very slightly curved. The plate covering the thorax (pronotum) is very long, extending back over the abdomen. When at rest, much of the forewing is concealed beneath it. The front corners (humeral angles) are not enlarged. It does not have a distinct projection (horn) at the front in the middle. The surface is not covered with longitudinal wrinkles. The longitudinal ridge in the middle (median carina) is complete, extending from the front margin to the tip, in all genera except Ophiderma. On the forewings (hemelytra), the R, M, and Cu veins are separated near the base. Large cells separate the veins near the base, so that they do not appear crowded. The R4+5 vein is merged with the M1+2 vein toward the base before the M fork. On the hindwing, the R4+5 vein is merged with the M1+2 vein for a great distance except in some tropical species. With few exceptions, it is not possible to identify Smiliini nymphs to the species level. |
