Male secondary sexual structures and the systematics of the Thereus oppia species group (Lepidoptera, Lycaenidae, Eumaeini).

Robbins RK, Heredia MD, Busby RC - Zookeys (2015)

Bottom Line: Diagnostic traits, especially male secondary structures, within the Thereus oppia species group are illustrated.Distributional and biological information is summarized for each species.Three species have been reared, and the caterpillars eat Loranthaceae.

ABSTRACT
The Thereus oppia species group includes species with and without a scent pad, which is a histologically and morphologically characterized male secondary sexual structure on the dorsal surface of the forewing. To assess the hypothesis that these structures are lost evolutionarily, but not regained (Dollo's Law), the taxonomy of this species group is revised. Thereus lomalarga sp. n., and Thereus brocki sp. n., are described. Diagnostic traits, especially male secondary structures, within the Thereus oppia species group are illustrated. Distributional and biological information is summarized for each species. Three species have been reared, and the caterpillars eat Loranthaceae. An inferred phylogeny is consistent with the hypothesis that scent pads in the Thereus oppia species group have been lost evolutionarily twice (in allopatry), and not re-gained.

Most parsimonious cladogram for of the Thereusoppia species group with unambiguous character state changes (22 steps, CI = 81, RI = 66). Hollow circles are homoplastic changes. Numbers to right of nodes in brackets are bootstrap values. The dorsal forewing scent pad (Character 12) was unambiguously lost twice. See text for further explanation.

Mentions: (Fig. 26). Costa Rica to the western slope of the Andes in Ecuador. It is allopatric with Thereusorasus, its hypothesized phylogenetic sister (Fig. 28). Their ranges overlap in Costa Rica and Panama, but in these countries, Thereuslomalarga is recorded below 1100 m and Thereusorasus at 1800 m.
