A Synopsis of Nearctic Adelid Moths, with Descriptions of New Species (Incuhvariidae )
1969 Journal of the Lepidopterists' So ciety 211 A SYNOPSIS OF NEARCTIC ADELID MOTHS, WITH DESCRIPTIONS OF NEW SPECIES (INCUHVARIIDAE ) JERRY A. POWELL1 University of California, Berkeley Adelids are small, brightly colored, day£Iying moths with exceptionally long antennae. They comprise a group of about 250 species of worldwide distribution, which usually has been assigned family status. However, these insects are closely allied to the Incurvariidae according to structures of the adults and probably will be considered a subfamily of the Incurvariidae by future writers in general. Forbes (1923) accorded the adelids subfamily rank along with the Prodoxinae (yucca moths) and the typical incurvariids, and Davis (1968) has used the same classifica tion. The three groups share similarities in mouthpart structure, wing venation, and male genitalia, and are unique among primitive Lepidoptera in the possession of a well developed piercing ovipositor with which the eggs are inserted into plant tissue. From related moths, the adelids are most easily distinguished by the greatly elongated antennae, which are often two to three times the length of the forewing in the males. A few species, including one described here, have relatively short antennae, slightly longer than the forewing in the male, and slightly shorter than the forewing in the female. TAXONOMY Present classifications propose six or seven genera 10 accomodate the world fauna. These include three large genera: Ceromitia, which is primarily South African in distribution; Nemophora (including Nemotois), which is widespread over the Pale arctic, Indo-Malayan, and Australian Regions; and Adela, which is mainly Holarctic, being well represented in both the Old and New Worlds.
