Doina paralagneia Clarke 1978

Doina paralagneia

Alar expanse 18–20 mm.

The description of the following, D. lagneia, will suffice for D. paralagneia except spot at middle of costa of forewing D. paralagneia more conspicuous than in D. lagneia and forewing with more of an orange tinge. Foretibia brownish or fuscous. Abdomen with ventromedian pocket containing scale tuft on first and second segments of male.

Male genitalia slides USNM 24122, 24124, 24125. Harpe broad, stubby, simple, scarcely longer than tegumen; cucullus rounded. Gnathos a transverse, oval, spined knob. Uncus as long as tegumen, somewhat truncated distally. Vinculum U-shaped. Tegumen about as broad as long. Anellus a strongly sclerotized subrectangular plate; from each corner, basally, a strongly sclerotized lobe, dilated distally; opposite corners, each with a papilla directed anteriorly. Aedeagus C-shaped; vesica armed with cluster of slender cornuti.

Female genitalia silde USNM 24123. Ostium very small, protruding lamella antivaginalis sclerotized, cupped. Antrum not differentiated. Inception of ductus seminalis from slightly before ostium. Ductus bursae long, looped, and reversed on itself. Bursa copulatrix oval, membranous; appendix bursae present, membranous. Signum a long, branched, sclerotized plate extending full length of bursa copulatrix.

HOLOTYPE.—USNM 73700.

TYPE-LOCALITY.—Centro-Austral.

Described from the male holotype, 2 male paratypes, Centro-Austral (Jan–Mar 1898, V. Izquerdo); male paratype, Arauco, Caramavida (1–6 Jan 1954, L. E. Peña): and one female paratype, Province Cautin, near Pucon (4 Jan 1966, O. Flint and Cekalovic).

This and the following fly together and are, for all intents and purposes, indistinguishable in the field. Even when one has the two side by side the only superficial character that can be used to separate them is the color of the foretibia, which is carmine or carmine-tinged on outer side in D. lagneia and brownish or fuscous in D. paralagneia. Moreover, the male of D. paralagneia has a ventromedial pocket, containing a scale tuft, on the first and second abdominal segments that is lacking in D. lagneia. Unfortunately, this character can only be seen in dissected specimens. The male genitalia present excellent characters for separation as can be seen from the figures. The differences between the aedeagi are so striking that there is no difficulty in distinguishing between them. Unfortunately, there is only one female specimen that I have placed with D. paralagneia on the color of the foretibia, so no comparison between the two species, based on females, can be made.

Doina paralagneia is a moth in the family Depressariidae. It was described by John Frederick Gates Clarke in 1978. It is found in Chile.

The wingspan is 18–20 mm. Adults are similar to Doina lagneia, except for a spot at the middle of the costa of the forewings, which is more conspicuous than in D. lagneia and the forewings have more of an orange tinge.
