Redingtonia alba

Redingtonia Barnes and McDunnough 1912

Redingtonia Barnes and McDunnough, 1912, Can. Ent., 44: 91.
Type species: Redingtonia alba Barnes and McDunnough, 1912. Original designation.

The genus Redingtonia contains the single species alba. The genus is readily recognized by the combination of;

1) The fore-shortened prothoracic tibia and tarsal segments,

2) The structure of the frontal process. The frontal process is similar to that of species currently placed in the Azeniini. The outer ring is absent. There is a lower tridentate plate. The medial process of this tridentate plate is much longer and more triangular than the two lateral projections. This central projection is connected by a medial lamina to an elongate, almost nose-shaped, dorsal process. The outer ring is absent.

3) A combination of the strongly developed frontal process and a mass of shaggy hair-like scales on the occiput of the head given the head a large, protuberant quality difficult to describe in words.

4) The rectangular, pure white forewings

5) Valve of male genitalia rectangular, elongate; corona absent, but spines strongest near apex of valve; digitus absent; clasper present, rectangular, about three times longer than wide, apex blunt, not pointed; basal process of sacculus absent.

6) base of vesica thickly covered with hair-like cornuti; two major groups of spine-like cornuti present, a long linear row and a shorter group of five or six setae opposite the longer group; smaller spine group not located on a distinct diverticulum; both spine groups located in heavily rugose portions of the vesica.

7) Female genitalia with heavy corrugations present in ventral ovipositor neck between ovipositor lobes; caudal margin of eighth abdominal segment with long spines; ostium a concave depression in the the eighth abdominal segment, covered with minute denticules; ductus bursae about six times longer than wide, membranous, but internally corrugated and with minute denticules along the corrugations of its apical fourth; junction of ductus bursae and corpus bursae broad and continued as a projection of the corpus bursae; corpus bursae globular with its largest portion projection caudally; appendix bursae present as a triangular projection of the corpus bursae directed to the right and toward in the head in a ventral view; corpus bursae without internal sclerotizations.

The larvae and foodplants are unknown.
