Phylogeny and Taxonomy of the Neotropical Thepytus (Lepidoptera: Lycaenidae: Theclinae)
نویسندگان
چکیده
The Neotropical lycaenid hairstreak genus Thepytus Robbins and its eight species are revised. Species treatments summarize nomenclature, distribution, habitat, behavior, and diagnostic traits, as well as noting why each species is considered distinct under a biological species concept. An identifi cation key for males and a checklist are included. Beatheclus Bálint & Dahners new synonym is synonymized with Thepytus, and Thepytus beatrizae (Bálint & Dahners) is a new combination. Other nomenclatural actions include the description of Thepytus jennifer Busby & Robbins new species, Thepytus nancyana Busby & Robbins new species, and Thepytus carmen Robbins & Duarte new species. A lectotype is designated for Thecla thyrea Hewitson, 1867, to ensure stability of this name. A phylogenetic analysis based on 22 coded morphological characters yields one equal weight most parsimonious 39-step tree. Implied weighting does not change the tree topology. Unambiguous changes in elevation optimized on the cladogram show that a montane lineage of Thepytus colonized the lowlands in at least one instance. The use of T. echelta (Hewitson) as a biological control agent for Psittacanthus (Loranthaceae) is discussed.

Two new Aphnaeus (Lepidoptera: Lycaenidae: Theclinae) species from Liberia.
Two new butterfly species belonging to the genus Aphnaeus (Lycaenidae: Theclinae), A. mirabilis sp. n., A. nimbaensis sp. n. were found in the Nimba Mountains, Western Range, Liberia in February 2012. Both are illustrated and described in comparison with closely related species: A. flavescens Stempffer, 1954 and A. liberti Bouyer, 1996, respectively. Genitalia of the male holotype of A. nimbaen...
متن کاملImmature stages of Calycopis caulonia (Hewitson, 1877) (Lepidoptera, Lycaenidae, Theclinae, Eumaeini), with notes on rearing detritivorous hairstreaks on artificial diet
Details of egg, larval, and pupal morphology are described and illustrated for Calycopis caulonia (Hewitson). In particular, larval chaetotaxy is documented for the first time in Calycopis. Lab methods for inducing wild-caught Calycopis females to lay eggs and for rearing larvae on artificial diet are reported. These methods may be useful in several ways in resolving the basic taxonomy of Calyc...
متن کاملChromosomal evolution in the South American Riodinidae (Lepidoptera: Papilionoidea).
We give the haploid chromosome numbers of 173 species or subspecies of Riodinidae as well as of 17 species or subspecies of neotropical Lycaenidae for comparison. The chromosome numbers of riodinids have thus far been very poorly known. We find that their range of variation extends from n = 9 to n = 110 but numbers above n = 31 are rare. While lepidopterans in general have stable chromosome num...

Larval Biology of Anthophagous Eumaeini (Lepidoptera: Lycaenidae, Theclinae) in the Cerrado of Central Brazil
The biology and morphology of the early stages of 22 species of Eumaeini (Lepidoptera: Lycaenidae, Theclinae) are presented. Observations were collected through the inspection of inflorescences in the field and the rearing of 214 larvae in laboratory. Allosmaitia strophius (Godart) associated with Malpighiaceae species and the polyphagous Strymon mulucha (Hewitson) were the most frequently coll...
