Primary types are designated with the words Holotype and Allotype in black text on red labels; paratypes are designated with the word Paratype in black text on yellow labels. <b>Etymology.</b> The epithet is derived from the type locality near which all of the known Louisiana specimens have been taken, the town of Abita Springs, St. Tammany Parish, Louisiana, USA. <b>Diagnosis.</b> <i>Lithophane abita</i> is a medium-sized species of <i>Lithophane</i> with a gray forewing and pinkish-fuscous hindwing. Th e forewing maculation tends to be pale and muted, except for a contrasting black line in the fold connecting the deeply zigzagged antemedial and postmedial lines. In these superficial characters, it has the appearance of some species in the <i>Lithophane lepida</i> Grote species-group of which only <i>Lithophane adipel</i> (Benjamin) (Fig. 3) occurs in southeastern United States. It is even more similar to <i>Lithophane thaxteri</i> Grote (Fig. 4), which like <i>L</i>. <i>abita</i>, has a brown flush to the area around the reniform spot and a black line defining the lower edge of the reniform spot, but <i>L</i>. <i>thaxteri</i> occurs in the boreal zone of Canada and in eastern United States as far south as New Jersey, but probably will not be found within the range of <i>L</i>. <i>abita</i>. The male genitalia of <i>L</i>. <i>abita</i>, however, are unique within the genus and the characteristic shape of the apices of the valves can be seen by brushing away some scales from the end of the abdomen. Th e digitus of the right valve projects beyond the apex of the valve as a long, curved, saber-like spine that is almost &amp;frac23; as long as the valve (Fig. 5); that of the left valve is short, stout, and apically blunt with the part of the digitus extending beyond the valve about ¼ of the length of that of the right valve. Th e spine-like process at the apex of the right valve can often be seen with the naked eye protruding from the end of the abdomen. The association of <i>L. abita</i> with bald cypress (<i>Taxodium distichum</i> Rich.), the probable larval host, is also unique within <i>Lithophane</i>. <b>Description.</b> Males and females similar in all external characters except size. <i>Head</i>: color usually light to medium slate gray, occasional specimens dark gray; pronounced frontal tuft; a wide lateral black band of scales on center of head between eyes defined above and below by a bright white line of scales, upper line at a position above eye and below antenna: antenna filiform, simple, slender, and acuminate, similar gray in color, more so dorsally and near base of shaft; labial palp with black scales laterally and gray scales ventrally and dorsally; labial palp peppered with either black or gray scales with white tips; ventral surface of palp with long scales forming a pointed tuft projecting anteroventrally slightly beyond apex of palp. <i>Thorax</i>: dorsal color similar to that of head and forewing ground color except for wide transverse dark brown band on prothoracic collar with upper margin defined by distinct black line with upper scales forming a bright white line; anterior part of thorax with dorsal partially divided tuft of scales; ventral color of thorax light pinkish brown, gray, or fuscous, with area between legs and wings entirely black; outer side of foreleg coxa a mixture of black and white scales (appearing gray to naked eye), with a short group of longitudinal black scales emanating from base; scales on the inner side of coxa brownish gray with a fine longitudinal line of black scales; femur covered with black and white scales (appearing gray to naked eye) with black scales more concentrated near trochanter; scales on coxa of midleg a mixture of gray and white, except near trochanter, where scales form a band of black followed by a band of white; similar black and white bands continue along remainder of midleg femur, tibia, and tarsus; hindleg similar in color and appearance to midleg. <i>Abdomen</i>: dorsal color fuscous with pink suffusion throughout; ventral color same as dorsal. <i>Forewing</i>: dorsal ground color matching that on dorsum of head and thorax; maculation varying from strongly marked to barely distinguishable; weakly marked specimens appear to have been on the wing longer, but do not necessarily appear exceptionally worn; most specimens with very faint, sometimes barely distinguishable, bifurcating black basal dash; antemedial (am) line mostly faint, deeply zigzagged, defined in paler gray and partly bordered on outer edge by black, except in area of fold where am line sharply defined in black forming an outward projecting “V” that extends into prominent, black dash in fold parallel to lower margin of wing and extends to postmedial (pm) line; pm line deeply serrated but faint, partly defined by pale gray and dark gray scales; subterminal line also faintly defined in pale and dark gray but usually bordered in subterminal area by series of diffuse, dark-gray, wedge-shaped spots; terminal area concolorous with medial area, or very slightly darker with wing veins partly defined in black; terminal line incomplete, dark gray, usually stronger between veins; orbicular spot a rounded or slightly oblong paler gray shade defined mainly by the darker gray shading surrounding it; a prominent crescentic black line extends from outer lower edge of orbicular spot and around lower margin of reniform spot; reniform spot barely distinguishable as a paler gray outline above black line on lower margin of spot; forewing with fuscous-brown scales in area between reniform and orbicular spots, and in lower part of reniform. Ventral color of forewing pale luteous brown on basal half of wing, pinkish brown on distal half and forming a darker marginal shade; reniform spot diffuse, dark brown, usually crescent-shaped; terminal line defined by faint black scales accentuated with conspicuous black scales forming v-shaped wedges between veins; fringe gray. Wing length: male: 16.7 mm (15.7–18.0, n = 25); female: 17.1 mm (15.6–18.4, n = 25). <i>Hindwing</i>: dorsal color fuscous with pinkish suffusion throughout; fringe contrastingly lighter slate gray, especially at base of fringe; terminal line usually expressed as diffuse darker brown lines most often only between veins on outer margin of wing; discal spot crescentic, darker than ground color but barely discernable.
