Nocloini New Genus 2 cordova (Barnes)

"Nocloa cordova"

Xanthia cordova Barnes, 1907, Canad. Ent., 39: 65.

Diagnosis: The basic forewing coloration of Nocloini New Genus 2 cordova is yellow with dull yellow-brown patches in the median area, particularly around the reniform. The basal area is yellow. The antemedial line is orange-yellow, and is sharply inwardly angulate near the orbicular spot. The orbicular spot is defined by a orange-yellow outer line and it rests in a patch of dull brown except along its ventral side. The reniform mark is large and completely surrounded by the dull brown patch of the outer and upper median area, and is generally more distinct than the orbicular mark. The patch of dull brown following the orbicular mark surrounds the reniform mark and accents the inner side of the postmedial line down to the vein Cu2. There is an obscure, dark brown dash along Cu2 from the postmedial line to the very vague medial line. The bottom half of the median area from the medial line to the antemedial line is of the same yellow color as the outer third and basal area. Both the subterminal and terminal areas of the forewing are yellow. The subterminal line consists of a series of dull red-brown dots. The male and female hindwings are light yellow without any maculation. The clasper of the valve in the male genitalia is completely absent and the valve is linear without a arcuate costa. The lateral diverticulum of the vesica has four or five spines. Wing length: mean = 10.96 mm, standard deviation = 0.47 mm, n = 10.

Adults have been collected in July, August, and September.

Distribution: Nocloini New Genus 2 cordova is not a particularly variable species. There is variation in the distinctness and shape of the forewing orbicular mark and whether the dark patch of the median area exists between the orbicular mark and the antemedial line. This species has a restricted distribution in the United States and is so far known only from Santa Cruz and Pima counties in southern Arizona. It has also been collected in southern Sonora in Mexico and probably occurs throughout the intervening region.

Identification Quality: Excellent.

Nocloini New Genus 0002 cordova

Nocloini New Genus 2 cordova is most likely to be confused with nanata. The maculation of nanata, however, is more obscure and the yellow of the forewing slightly lighter than that of cordova. The reniform mark is distinct and completely surrounded by dull brown in cordova. In contrast the reniform mark in nanata is open dorsally. The antemedial and postmedial lines, although not prominent, are both present in cordova, but are both absent in nanata. Both the male and female hindwing of nanata have some dull brown suffusion along the upper half of the outer margin. There is no such suffusion in either the male or female hindwing of cordova. The clasper of the valve in the male genitalia is completely absent in cordova, but there is a small clasper present in nanata. The costa of the valve is straight in cordova, but slightly arcuate in nanata.
