Eupterote elisavetae sp. nov. from Flores Island, Indonesia (Lepidoptera: Eupterotidae)

Although the Odonata are common inhabitants of various extreme environments such as geothermal springs, brackish wetlands, mangroves, and volcanic lakes, the assemblages of this group associated with extreme habitats in Australasia are rather poorly known. Here, we combine museum collection data and published reports on Odonata from extreme habitats on Flores Island, Lesser Sunda Archipelago. The highly acidic Sano Nggoang Crater Lake (mean pH = 3.17) on Flores houses seven species as follows: Agriocnemis pygmaea, Xiphiagrion cyanomelas (Coenagrionidae), Neurothemis ramburii, Orthetrum pruinosum pruinosum, O. sabina, O. testaceum soembanum (Libellulidae), and Anax gibbosulus (Aeshnidae). A coastal marsh site with slightly brackish water on Flores harbors at least five dragonfly species as follows: Diplacodes trivialis, Neurothemis intermedia excelsa, N. terminata, Pantala flavescens, and Rhyothemis phyllis ixias (Libellulidae). The migratory dragonfly Pantala flavescens was a single species recorded on the waterless Kanawa Island near the western edge of Flores. Our findings suggest that extreme habitats in eastern Indonesia primarily colonized by widespread generalist Odonata species. Finally, an updated checklist of Odonata species recorded from Flores Island was compiled. Our survey of museum specimens recovered two species not found on existing species lists for Flores: Neurothemis intermedia excelsa and Pantala flavescens.

“…The type series of the new species and samples of Amerila astreus were studied in the Lepidoptera collection of the Russian Museum of Biodiversity Hotspots [RMBH], N. Laverov Federal Center for Integrated Arctic Research of the Ural Branch of the Russian Academy of Sciences, Arkhangelsk, Russia. The specimens and genitalia processing and photographing followed those described in our earlier works Spitsyn & Bolotov 2020;Spitsyn & Potapov 2020). Diagnosis.…”

“…This insular group harbors a largely endemic Lepidoptera fauna (e.g. Yakovlev 2015;Bolotov et al 2017;Spitsyn & Potapov 2020), revealing up to 90% of local endemic species in several families (Zolotuhin & Witt 2005;Zolotuhin 2009;Spitsyn & Bolotov 2020). In general, the fauna of tiger and lichen moths (Lepidoptera: Erebidae: Arctiinae) of the Lesser Sundas is still insufficiently known, while the insular endemism in this remote archipelago reaches relatively high levels, e.g.…”

The Flores Island is a part of the East Nusa Tenggara Group belonging to the Lesser Sunda Archipelago. The Lepidoptera fauna of this remote island comprises two species of the genus Amerila Walker, 1855, i.e. Amerila astreus (Drury, 1773) and Amerila rosenfeldae sp. nov. The first species is widespread from India and Southeast Asia to New Guinea, while the latter taxon appears to represent a lineage endemic to Flores.

“…The proportion of endemic species is higher in groups with low dispersal capabilities, e.g. Lasiocampidae (Zolotuhin & Witt 2005;Zolotuhin 2009;Spitsyn et al 2019;Spitsyn & Potapov 2020) and Eupterotidae (Nässig et al 2009;Nässig & Bouyer 2010;Spitsyn & Bolotov 2020).…”

Here, we describe Theretra makhrovi sp. nov., a new hawk moth species from Flores Island, East Nusa Tenggara, Indonesia. This species is most similar to Theretra acuta Vaglia & Liyous, 2010 and T. rhesus (Boisduval, [1875]) but can be distinguished from these taxa by the lack of several marking features such as narrow yellow stripes on the tegula, a large, triangular black spot on the underside of the forewing, and a clear zigzag curved band on the underside of the hindwing. The new species has pink shading on the underside of both wings that is absent in the two other species. It also has narrower and longer wings and specific male genitalia structure compared with the two similar taxa.
