Nine previously unrecognized species of Phaneta Stephens (Tortricidae) are described from western North America: P. browni, P. arenana, P. labiata, P. goblinana, P. cibolana, P. parvula, P. clementeana, P. baloghi, and P. vogelana. Reviewed are: Phaneta corculana (Zeller) and Phaneta mormonensis (Heinrich), which have male genitalia similar to those of P. browni and P. arenana; Phaneta indagatricana (Heinrich) and Phaneta misturana (Heinrich), due to similarity in forewing pattern with P. labiata and P. goblinana; Phaneta stramineana (Walsingham), Phaneta parvana (Walsingham), and Phaneta grindeliana (Busck), close relatives of P. clementeana; P. minimana (Walsingham), a species misidentified in North American collections for more than eighty years; and Phaneta latens (Heinrich), which is similar in male genitalia to P. labiata. Phaneta verecundana Blanchard is recognized as a synonym of P. indagatricana. Adults and genitalia are illustrated for each species.

A new riodinid species in the tribe Symmachiini, Lucillella arcoirisa Hall & Willmott n. sp., is described from the eastern Andes of Ecuador. All five true members of the genus Lucillella Strand, 1932, are figured, and their known geographic ranges are mapped. Lucillella is hypothesized to be monophyletic with the exclusion of suberra Hewitson, 1877, and the sister genus is hypothesized to be Esthemopsis C. & R. Felder, 1865. The new Lucillella species was discovered in the forest canopy using the single rope technique. The equipment and procedures used in this canopy access method are described and illustrated.

The new genus Chiricahua is described from moths collected in the Chiricahua Mtns., Cochise Co., Arizona. Two species are recognized: the new species C. lichenaria, the type species for the genus, and C. multidentata. previously placed in Biston. Adults and genitalia are illustrated.

A 10-year survey was conducted within the pine rocklands of Everglades National Park to study the status, phenology and natural history of Strymon acis bartrami (W. Huntington and Comstock). The response of populations of this species to prescribed fires and hurricane activity within the Everglades was also noted. Strymon a. bartrami (n = 77 adults) was encountered throughout the survey, most often in the spring, but was generally uncommon. The species was slow to re-colonize recently burned pine rocklands. However, prescribed fires conducted in a cyclic pattern as well as near appropriate hostplant-bearing refugia may have aided S. a. bartrami in post-burn re-establishment. In addition, the species appeared to recover quickly after hurricane events in the Everglades.

The widely reported isolate population of Oeneis chrysus from Mt. Withington, Socorro County, New Mexico, is formally described as Oeneis chryxus socorro.

I here describe Satyrium titus carrizozo, the third of three endemic hairstreaks, and of five endemic Lycaenids occurring in the Sacramento Mts. of southern New Mexico. This is the only mountain range in New Mexico isolated long enough to have evolved endemic subspecies of Lepidoptera—my Antiquity Formula places its time of separation from the nearest area of potential gene-exchange as about 8000 years ago. The new taxon differs from other known Coral hairstreak populations by having both the VHW namesake coral and the inner coral whitecapping in the “thecla-spot” greatly reduced.

A new subspecies of Eueides lampeto Bates, 1862 (Nymphalidae: Heliconiinae), E. l. brownsbergensis, is described from Suriname; its sexual dimorphism and involvement in mimicry complexes in Suriname is discussed.
