Costa (Mauro), Grishin (Nick V.), Lamas (Gerardo), Viloria (Ángel L.), Benmesbah (Mohamed), García (Marcial) and Neild (Andrew F. E.). New Pieridae (Dismorphiinae) from northern Venezuela. [22 p.]
A new species and a new subspecies of Lepidoptera (Papilionoidea) are described from two isolated mountain ranges in northern Venezuela: Lieinix lamasi Costa, Grishin & Neild, n. sp. from the Serranía del Turimiquire, and Lieinix nemesis falconiana Neild & Costa, n. ssp. from the Sierra de San Luis (Pieridae, Dismorphiinae). An annotated list of endemic butterflies from the aforementioned still little explored mountain ranges is presented for the first time, with considerations on endemism and biogeographic characterization. A hypothesis is proposed, based on current evidence, regarding the identity and type locality of Lieinix nemesis nemesis (Latreille, 1813), whose type material is lost. The hitherto unknown female of Lieinix christa christa (Reissinger, 1970) is illustrated.
Herbin (Daniel). New species of Zanola Walker, 1855 (Lepidoptera Apatelodidae). [5 p.]
In preparation for a revision of the genus Zanola Walker, 1855, some new species are described, mainly from the Witt collection in ZSM. This is the first part of the preparatory work. Habitus and male genitalia are figured.
Page (Nino) and Leroy (Maeva). A new species of Mesosemia Hübner, [1819], from submontane cloud forests in French Guiana (Lepidoptera Riodinidae). [15 p.]
A short expedition to the ridgetop of Bellevue de Maripasoula (640 m asl) and another to Kotika Mountain (710 – 740 m asl) one year later, both organized by the Parc Amazonien de Guyane (PAG), enabled the discovery of a new and distinctive species of Mesosemia Hübner, [1819]. Mesosemia lermytei n. sp. is described in this article, based on a series of twenty-seven male and two female specimens, which association is confirmed by direct observation of mating, morphology and COI barcoding. This new species appears moderately related to M. ephyne (Cramer, 1776) and M. lycorias Stichel, 1905.
M. lermytei n. sp. is so far believed to be very local and most probably restricted to submontane « cloud forests » in Central-Western French Guiana, a peculiar habitat appearing from 500 m asl upwards in a region where lowland terra firme forest is otherwise predominant. Field observations on male territorial behaviour and candidate habitat are provided. The larval biology of this new species remains unknown. If indeed associated with submontane forests, M. lermytei n. sp. should be considered patrimonial given the scarcity of that habitat across oriental Guianas.
