Etymology.

We name this species after Vernon A. Brou, Jr. in recognition of his impressive and tireless efforts in collecting and researching the Lepidoptera of Louisiana.

Diagnosis.

This species occurs with Doryodes latistriga , Doryodes reineckei , and Doryodes tenuistriga in coastal salt marsh habitats from Alabama to southern Texas. Doryodes broui is superficially indistinguishable from Doryodes spadaria , but differs from it in male genitalia, barcodes, and occurs far to the west of the known range of Doryodes spadaria . It can be distinguished from Doryodes reineckei in having a sharply-defined longitudinal dark stripe on the forewing, and from Doryodes latistriga by the narrower forewing stripe in Doryodes broui . It is most likely to be confused with Doryodes tenuistriga , which typically is larger, but because of variation in both species, some specimens must be dissected or barcoded, for positive identification. The male genitalia of Doryodes broui are most similar to those of Doryodes latistriga , but the diverticula and cornuti are smaller, especially the terminal diverticulum (# 5), which is short and rounded, not elongated as in Doryodes latistriga .

Description.

Forewing length: 13.0-15.5 mm (males), 13.5-17.0 mm (females), Forewing buffy brown to whitish gray with faint buffy streaks, darker forms in colder months; longitudinal stripe dark brown, similar in width to that of Doryodes spadaria , narrower than for Doryodes latistriga , wider than for Doryodes tenuistriga . Male genitalia. Aedeagus 8 × as long as mesial width; vesica with dorsolateral toothed triangular cornutus on left side of basal part of vesica distal to end of aedeagus; a sclerotized plate in anterior 90° bend in vesica at position of ductus seminalis; posterior curve in vesica extended posteriorly into rounded diverticulum 1 with toothed preapical cornutus; diverticulum 2 on left side reduced to low bulge with large conical cornutus in middle; preapical posterior diverticulum (# 4) tapered with conical cornutus at distal base and also at base of short rounded apical diverticulum 5. The female genitalia are similar to those of Doryodes latistriga , but the appendix bursae is rounded posteriorly and only lightly sclerotized.

Distribution and biology.

Doryodes broui occurs from Alabama to southern Texas. Nothing is known of its biology. Adults occur throughout the year, but concentration of collecting dates suggests a primary brood between mid-March and mid-June and a secondary protracted brood between late July and mid-October (V.A. Brou Jr. pers. comm.).
