TL;DR: Loranthomitoura, new genus, is described for five North American hairstreak butterflies which utilize Arceuthobium as a larval host and characteristics of the immature stages, especially first instar chaetotaxy indicate that Loranthom itoura may have greater affinity with Incisalia.
Abstract: Loranthomitoura, new genus, is described for five North American hairstreak butterflies which utilize Arceuthobium as a larval host. These species were previously placed in the genus Mitoura with other taxa which utilize hosts in the Cupressaceae. Separation of Loranthomitoura from Mitoura is based primarily on characteristics of the immature stages, especially first instar chaetotaxy. Larval and adult features indicate that Loranthomitoura may have greater affinity with Incisalia.
TL;DR: The eumaeine lycaenid Atlides halljasoni n.
Abstract: The eumaeine lycaenid Atlides halljasoni n. sp. is described from Ecuador and chacracterized by spectrography. Its intrageneric relationships are discussed. The genus Riojana is reinstated from the synonymy of Atlides.
TL;DR: Two species of hairstreak butterflies (Lepidoptera: Lycaenidae: Theclinae): Atlides gaumeri and Chalybs hassan have been rediscovered for the first time since the late 1800s or early 1900s in Guatemala.
Abstract: . We report two species of hairstreak butterflies (Lepidoptera: Lycaenidae: Theclinae) collected in Guatemala. Atlides gaumeri (Godman 1901) was recorded for the first time in the country, and Chalybs hassan (Stoll 1790) has been rediscovered for the first time since the late 1800s or early 1900s.
TL;DR: It is concluded that male secondary sexual organs in the Atlides Section function primarily for species recognition and thereby promote sympatric diversification.
