Nocloini New Genus dissimilis (Barnes and McDunnough)

"Nocloa dissimilis"

Nocloa dissimilis Barnes and McDunnough, 1910, Jour. New York Ent. Soc., 18: 157.

Diagnosis: The general color of dissimilis is rich brown. The forewing median area is darker than either the basal or subterminal regions. Vague, white scaling is present in the median area, particularly along vein A2 and CU. The antemedial line is scalloped and accented with black on its outer side. The claviform mark is absent. The orbicular mark is small and round with a distinctly lighter outer ring. The reniform mark is filled with dull white. The medial line is dark brown, but not strong, and runs very near the postmedial line ending at the bottom of the reniform mark. The postmedial line is weakly scallped and is dull white, preceded in the median area by black. The subterminal line is highly irregular, slightly lighter than the group color of the outer third of the forewing, and is never very strong. The hindwing is dull brown. A postmedial line is present. The frontal process is distinctive. The only visible portion not covered by scales is a small, round central protuberance. Wing length: mean = 14.83 mm, standard deviation = 0.69 mm, n = 10.

Adults have been collected in August and September.

Distribution: Nocloini New Genus 5 dissimilis has been most commonly collected in southeastern and south-central Arizona in Cochice, Pima, and Santa Cruz counties. A single female specimen from Los Angeles county, California exists in the USNM. This Californian specimen is different from all of the Arizona specimens because the median area is not distinctly darker than the basal and subterminal regions, the postmedial line is much more strongly accented with black, and the white of the antemedial and postmedial lines is nearly absent. The female genitalia of this single specimen are not significantly different from those of specimens from southern Arizona. However the corpus bursae is slightly more elongate and the ovipositor slightly longer and thinner. More material from California is needed to determine the status of this population. Some variation exists in the Arizona specimens in the darkness of the hindwing coloration. No significant variation exists in the forewing.
