Materiales sobre la fauna de Lepidoptera del Parque Natural Ecoportal de Piedra (Provincia de Jujuy, noroeste de Argentina). Parte I. Pterophoridae (Lepidoptera)

Introduction

The studied area is located in the Subtropical Montane Cloud Forests of Northwestern Argentina or Southern Yungas. In Argentina the Southern Yungas covers an extension of 700 km long and less than 50 km wide (from 22º 11’ S 64º 37’ W to 28º 51’ S 65º 51’ W). Along the latitudinal range three sectors can be distinguished, i.e., northern, central, and southern. The area is located within the central sector of the Southern Yungas (24º 06’ S to 64º 26’ W). This ecoregion is characterized by an elevational gradient where different vegetation types can be recognized from 600 to 2200 m above sea level (a.s.l.). The vegetation communities can be divided into: piedmont forests (from 600 to 900 m a.s.l.), montane forests (from 900 to 1400 m a.s.l.), cloud forests (from 1400 to 2000 m a.s.l.), and Polylepis forests with high altitude grasslands (from 2000 to 2500 m a.s.l.). The first three forest types have a canopy height of about 20 to 30 m, while the latter is more a shrubland (less than 10 m in height). Mean annual rainfall is 1395 mm with 85% of the rainfall concentrated in the Austral summer (November to March). There is also a high input of humidity provided by fog even in the dry season that ensures that watersheds are supplied with water year-round. Many research studies highlight the importance of the Southern Yungas as harboring a high diversity of environments that allows high species richness. The area contains important habitat and populations of species of high conservation value. For example, several endemic bird species of the Southern Yungas, such as, Tucuman parrot (Amazona tucumana (Cabanis, 1885)) categorized as Vulnerable by the IUCN and included in CITES I, Mountain Cracidae (Penelope dabbenei Hellmayr & Conover, 1942), Blue-fronted Hummingbird (Eriocnemis glaucopoides D’Orbigny & Lafresnaye, 1838), Yellow-striped Brush-finch (Atlapetes citrinellus (Cabanis, 1883)), White-browed Tapaculo (Scytalopus superciliaris Cabanis, 1883) and Slaty Elaenia (Elaenia strepera Cabanis, 1883), raptors, such as: King vulture (Sarcoramphus papa (Linnaeus, 1758)), Andean condor (Vultur gryphus Linnaeus, 1758), and two very rare species Plushcap (Catamblyrhynchus diadema Lafresnaye, 1842) and Rufous-bellied saltator (Pseudosaltator rufiventris (D’Orbigny & Lafresnaye, 1837)). Among the mammal species: the tapir (Tapirus terrestris (Linnaeus, 1758)) categorized as Vulnerable by the IUCN and collared peccari (Dicotyles tajacu (Linnaeus, 1758)) are frequently seen. Tree species, such as, the Austral Pine (Podocarpus parlatorei Pilg.) included in CITES I, Polylepis hyeronymii Pilger, Southern Ceders (Cedrela lilloi Sessé & Moc. Ex DC. and C. balansae C. DC.), Myroxylon peruiferum L., Quebracho (Schinopsis haenkeana Engl.), among many other (estimated to be 128 species woody species). The property falls within an Important Bird Area (IBA) - Reserva Natural Las Lancitas (AR021) and a Key Biodiversity Area (KBA) - Reserva Natural Las Lancitas.

The Pterophoridae of Argentina are relatively well studied. According to publications, 63 species of them are known (BERG, 1885; STAUDINGER, 1899; MEYRICK, 1908, 1931, 1932; GIELIS, 1989, 1991, 1996, 2003, 2006, 2011, 2012, 2013; PASTRANA, 1989). For the Jujuy province only 6 species were given: Michaelophorus dentiger (Meyrick, 1916), Oidaematophorus praenigratus (Meyrick, 1921), Singularia alternaria (Zeller, 1874), Hellinsia glaphyrotes (Meyrick, 1908), and Emmelina jason (Meyrick, 1930) (GIELIS, 2011, 2013). Hellinsia navarroi Gielis, 2013, has been described from the Jujuy province in the vicinity of the region mentioned in this article.

In 2019, a Russian entomological expedition was conducted in North-Western Argentina (mostly, to the province Jujuy). The expedition members were: Vyacheslav Doroshkin (Chelyabinsk), Sergey Reshetnikov (Novosibirsk) and Roman Yakovlev (Barnaul). Two species of Cossidae (Uretiana silviae Yakovlev, Naydenov & Penco, 2020 and Psychonoctua diiorioi Yakovlev, Penco & Naydenov, 2020) collected from Eco Portal de Piedra was described (YAKOVLEV, NAYDENOV & PENCO, 2020; YAKOVLEV, PENCO & NAYDENOV, 2020). This publication opens a series of articles devoted to the local fauna of Lepidoptera in the private nature reserve Eco Portal de Piedra.

As a result of our studies, the Pterophoridae fauna of Argentina increased by 8 species and now includes 71 species.

Material and methods

The Pterophoridae were collected at twilight and at night on the territory of the private nature reserve Eco Portal de Piedra (Figs. 1-4) from 20-X to 05-XI-2019 using light traps. The studied specimens are deposited in the collection of the Zoological Institute St. Petersburg, Russia (ZISP) and in the Collection of P. Ustjuzhanin and V. Kovtunovich (Novosibirsk and Moscow, Russia, ÑUK). The holotypes and part of the paratypes of the new species are deposited in the collection ZISP.

Type material: Holotype: 1 ♂, ARGENTINA, Jujuy Prov., Santa Barbara Mts., 12 km SW Palma Sola, Eco Portal De Piedra NP, 24º05’42,6” S 064º23’56,9” W, H-1045 m, 29-X-02-XI-2019, R. Yakovlev, V. Doroshkin, S. Reshetnikov leg. (ZISP, gen.pr. Nr.1926). Paratypes: 7 ♀♀, same data as holotype, (ZISP, 1927, CUK), R. Yakovlev, V. Doroshkin and S. Reshetnikov leg.

Description: External characters. Head, thorax and tegulae light-grey. Labial palpi thin, short. Antennae thin, light-brown. Wingspan 17-19 mm (holotype - 17 mm). Fore wings yellowish-grey. Dark-brown elongated spot along costal edge, above cleft. First lobe apically sharp, ending with small brown point. Distinct rectangular dark-brown spot before cleft. Less expressed brown spot basally. Second lobe lanceolate, apically sharp, interspersed with small brown scales. Hind wings unicolorous, light-grey. Hind legs light-brown, with portions of darker brown scales at bases of spurs.

Male genitalia: Valves symmetric. On both valves, sclerotized saccular processes arcuately curved distally. Uncus simple, thin, curved almost at right angle. Anellus arms thin, almost straight. Vinculum long, distally widened. Aedeagus thin, slightly curved, twice shorter than valve.

Female genitalia: Papillae anales triangle. Posterior apophyses long, slightly curved distally. Antrum narrow, tubulate. Ductus bursae quite long, thin, membranous. Ductus seminalis thin, passes into bursa copulatrix together with ductus bursae. Bursa copulatrix oval, membranous.

Diagnosis: The new species is similar to Emmelina jason (Meyrick, 1930) in the long vinculum, but clearly differs by its saccular processes on both valves, the curved uncus and the curved aedeagus.

Distribution: Argentina.

Flight period: October-November.

Etymology: the species is named after Vyacheslav Doroshkin (Chelyabinsk, Russia), an entomologist-naturalist, a member of the expedition to North-western Argentina.

Emmelina reshetnikovi Ustjuzhanin & Kovtunovich, sp. n. (Figs. 8-9)

Type material: Holotype: 1 ♂, ARGENTINA, Jujuy Prov., Santa Barbara Mts., 12 km SW Palma Sola, Eco Portal De Piedra NP, 24º 05’ 42,5” S 064º 23’ 56,8”’ W, H-1045 m, 19-22-X-2019, R. Yakovlev, V. Doroshkin and S. Reshetnikov leg. (ZISP, gen.pr. Nr. 1928).

Description: External characters. Head, thorax and tegulae light-brown. Labial palpi thin, straight, slightly longer than longitudinal eye diameter. Antennae thin, light-brown. Wingspan 22 mm. Fore wings light-brown. Narrow dark-brown elongated spot along costal edge, above cleft. First lobe apically sharp. Small dark-brown spot before cleft. Second lobe apically sharp. Fringe inside cleft noticeably darker than basic background of wing. Hind wings unicolorous, light-brown. Hind legs light-brown, with portions of darker brown scales at bass of spurs.

Male genitalia: Valves asymmetric, left valve significantly wider than right. Harpe on left valve of a complicated structure: in lower inner part, on wide sclerotized plate, an apically sharp process shaped as slightly curved spike. Short undulated apically sharp outgrowth extending from base of this process. Dense spiky bristles on outer distal part of the said above plate. Arched saccular process on right valve. From it, harpe shaped as wide plate, extends. Its top ending with small thin finger-like process. Uncus short, apically sharp. Anellus arms thin, long. Vinculum wide, short. Aedeagus thin, slightly concave.

Diagnosis: In the male genitalia, in the shape of the right valve and its structural elements, the new species is similar to the African species Emmelina amseli (Bigot, 1969) and Emmelina bigoti Gibeaux, 1990, but clearly differs in the shape and structure of the left valve and the aedeagus, and also in the wide vinculum.

Distribution: Argentina.

Flight period: October

Etymology: The species is named after Sergey Reshetnikov (Novosibirsk, Russia), an entomologist-naturalist, a member of the expedition to North-western Argentina.

Discussion

The collected material is just a small fragment of Eco Portal De Piedra fauna. Basing on the material studied, it is impossible to carry out a detailed arealogical analysis of the fauna or to publish a list of species claiming to be complete. We think that the private reserve Eco Portal De Piedra is a reference site for subtropical forests of Northern Argentina, which can be the basis for promising projects for the study of the biota in Northern Argentina.
