Abstract Two new species of plume moths from Atacama Desert, Chile, are described: Lioptilodes karinupponeni Ustjuzhanin, Kovtunovich & Pototski sp. nov. and Hellinsia haverineni Ustjuzhanin, Kovtunovich & Pototski sp. nov.

Key words: Biodiversity, Lepidoptera, Pterophoridae, plume moths, Chile, Atacama, new species, new data.

Introduction

Plume moths of Chile are relatively well studied, there are over 50 known species of them (Gielis 1991, 2003, 2006, 2011, 2012, 2013, 2014; Vargas 2010, 2020; Vargas & Parra 2005; Vargas et al. 2020), but for Atacama Desert our data are published for the first time. The material was collected during January–February 2017 in the course of a Finnish–Estonian expedition in the narrow low belt between the Andes Mts. and the Pacific in the Central Chile (Figs. 6-7). The collected species came at night to various UV-lights. The habitats were semi-march and bushlands. The holotypes and part of the paratypes are deposited in the Institute of Agricultural and Environmental Sciences, Estonian University of Life Sciences, Tartu, Estonia (IZBE), the paratypes – in the Zoological Institute of Russian Academy of Science St. Petersburg (ZISP), Research collection of Kari & Timo Nupponen, Espoo, Finland (NUPP) and the Collection by P. Ustjuzhanin and V. Kovtunovich (CUK).

Figure 1. Lioptilodes karinupponeni Ustjuzhanin, Kovtunovich & Pototski sp. nov. Adult, male, holotype.

Description: External characters. Head, thorax and tegulae brown. Labial palpi light-brown, directed upwards, distally extended, 1.5 times longer than longitudinal eye diameter. Antennae brown. Wingspan 11-12 mm, in holotype – 11.2 mm. Fore wings greyish-brown. Brown spot in base of cleft, longitudinal brown stroke in medium part of wing. Hind wings unicolorous, color the same as of fore wings. Fringe on all wings light-grey. Hind legs light-brown, spurs basally darkened with dark-brown scales. Male genitalia: Valves symmetric, distally narrowing. Uncus extended from base to apex, distally noticeably narrowing. Tegumen broad, W-shaped. Anellus arms relatively wide, of equal length. Saccus wide, rectangular. Aedeagus 1.5 times shorter than valve, with process in medium part, distally thick, apically narrow.

TWO NEW PLUME MOTHS FROM ATACAMA DESERT

Female genitalia: Papillae anales oval. Posterior apophyses long, thin. Lamina vaginalis wide, bi- lobed. Antrum tubulate, sclerotized. Ductus short, membranous, directly passing into oval bursa copulatrix. Two short needle-like signa on sides of bursa copulatrix.

Figure 2. Lioptilodes karinupponeni Ustjuzhanin, Kovtunovich & Pototski sp. nov. Male genitalia, holotype (IZBE gen.pr. Nr. 3042358).

Differential diagnosis. In the male genitalia, in the wide rectangular saccus, the new species is similar to Lioptilodes gualaceo Gielis, 2014, but clearly differs in the distally narrow uncus, distally narrow valves and the shape of the aedeagus. Externally, the adult is similar to Lioptilodes aguilaicus Gielis, 1991, from which it differs in the much smaller size and the genital structure.

Distribution: Chile, Atacama.

Flight period: January - February.

Etymology: The species Lioptilodes karinupponeni is named in honor of a Finnish lepidopterologist Kari Nupponen, a member of the Estonian Society of Lepidopterologists and member of many other countries lepidopterologists societies, who is a dedicated to study of moths and a member of many joint expeditions with Aleksander Pototski and Risto Haverinen.

Type material: Holotype, male, (IZBE gen.pr. Nr. 3042360), CHILE ATACAMA, Huasco River valley by Huasco Bajo vill. 31.i.2017, 28°28'S, 71°09'W, 31m, K. Nupponen & R. Haverinen leg.; Paratypes: 9 males, same data as holotype, K. Nupponen, R. Haverinen & A. Pototski leg. (IZBE, NUPP, ZISP, CUK).

Description: External characters. Head with collar of brown scales and white hairs on forehead. Thorax and tegulae ocher-yellow. Labial palpi thin, light-yellow, equal to longitudinal eye diameter in length. Antennae light-brown. Wingspan 16-19 mm, in holotype – 17.5 mm. Fore wings yellowish-brown, interspersed with tiny brown scales. Brown spot in base of cleft. Small brown strokes along inner margin of first and second lobe distally. Hind wings unicolorous, color the same as of fore wings. Hind legs pale-yellow, with spurs of different length.

TWO NEW PLUME MOTHS FROM ATACAMA DESERT

Figure 4. Hellinsia haverineni Ustjuzhanin, Kovtunovich & Pototski sp. nov. Adult, male, holotype.

Male genitalia: Valves asymmetric, left valve significantly wider than right valve. Saccular process on left valve thin, slightly concave, reaching middle of valve. Sacculus on right valve distally extended, long longitudinal fold in medium part of valve. Anellus arms of different length, right arm slightly longer, both arms apically acute. Saccus arched. Uncus narrow, thin, in length equal to saccular process of left valve. Tegumen short, v-shaped. Aedeagus almost twice shorter than valve, slightly concave, with narrow long cornutus. Female: unknown.

Differential diagnosis. In the external characters of the adult and in the male genitals, the new species is most close to Hellinsia angulofuscus (Gielis, 1991), from which it differs in the absence of the long brown stroke on the costal margin on the fore wing above the cleft. The new species has a small round point in the cleft base, while in H. angulofuscus there is a long stroke there. The left valve in the new species is wide, significantly more extended than the right one, while in H. angulofuscus the left valve is narrow. The aedeagus in H. angulofuscus is swollen apically, while in the new species it is narrow.

Distribution: Chile, Atacama.

Flight period: January.

Etymology: The species Hellinsia haverineni is named in honor of a Finnish lepidopterologist Risto alias Ripa Haverinen, who is a member of the board of the Estonian Society of Lepidopterologists and member of many other countries lepidopterologists societies, always a helpful friend and member of dozens joint expeditions with Aleksander Pototski and Kari Nupponen.

Additionally, in the studied territory we have collected the following Pterophoridae species previously known for Chile but found in Atacama Desert for the first time:
