The micromoth fauna of the arid environments of the western slopes of central Andes remains poorly explored. Plants native to this area host overlooked species. A survey for micromoth larvae on the Chilean endemic Steviaphilippiana Hieron. (Asteraceae) was performed.
New information
The first records of plume moths (Lepidoptera, Pterophoridae) associated with S.philippiana are provided. Adults of Adainajobimi Vargas, 2020 and a new species of Oidaematophorus Wallengren, 1862 were reared from larvae collected on inflorescences and leaves, respectively. Oidaematophorusandresi sp. n. is described and illustrated. A phylogenetic analysis of mitochondrial DNA sequences clustered each of the two plume moths with the type species of its respective genus. These records expand the host plant range of A.jobimi and add a second species of Oidaematophorus to the Chilean fauna of plume moths.
Along the altitudinal gradient of the northernmost part of Chile, extending from sea level to the highlands of the Andes, the highest plant diversity occurs in a narrow altitudinal belt around 3500 m elevation (Arroyo et al. 1988, Rundel et al. 2003, Moreira-Muñoz et al. 2016). The micromoth fauna of this altitudinal belt remains poorly explored. However, recent studies revealed that native plants host previously overlooked species, including representatives of the family Pterophoridae (Vargas et al. 2020), suggesting that surveys for larvae on these plants could help to improve the understanding of the micromoth diversity of this area.
The Chilean endemic Steviaphilippiana Hieron. (Asteraceae) is a morphologically variable shrub or subshrub whose geographic distribution is restricted to two disjunct areas in the north of the country, one at high elevations on the western slopes of the Andes between 18 and 19°S, the other near sea level on the coast of the Atacama Desert between 22 and 26°S (Gutiérrez et al. 2016). Surveys for micromoth larvae in the Andes revealed that two species of plume moths belonging to two genera of the tribe Oidaematophorini (Pterophorinae) use S.philippiana as a host. The aim of this study is to provide these records, including the description of a new species of Oidaematophorus Wallengren, 1862. Furthermore, as some genera of Oidaematophorini have remarkably similar morphology (Gielis 2011), the generic assignment of the two species reared from S.philippiana was assessed using phylogenetic analysis of mitochondrial DNA sequences.
Materials and methods
The study site is about 2 km south of Socoroma Village (18°16’42’’S, 69°34’15’’W) in the Parinacota Province of northern Chile, at about 3400 m elevation on the western slopes of the Andes. It has a tropical xeric climate with seasonal rains concentrated mainly in summer (Luebert and Pliscoff 2006). Mature plume moth larvae were collected on S.philippiana in March 2021 and April 2022. The collected larvae were placed in plastic vials with inflorescences or leaves, depending upon which plant organ they were feeding on in the field with a paper towel at the bottom. The emerged adults were mounted following standard procedures. For genitalia dissection, the abdomen was removed and placed in hot 10% potassium hydroxide (KOH) for a few minutes. The genitalia were stained with Eosin Y and Chlorazol Black and mounted on slides with Euparal. Photos of the adults were taken with a Sony CyberShot DSC-HX200V digital camera. Photos of the genitalia were taken with a Leica MC170 HD digital camera attached to a Leica DM1000 LED light microscope. Each image of the genitalia was constructed with 3–10 photos assembled with the software Helicon Focus 8. The specimens studied are deposited in the “Colección Entomológica de la Universidad de Tarapacá” (IDEA), Arica, Chile.
Two pupae reared from larvae collected on inflorescences and two legs from a female and a male adult reared from larvae collected on leaves were used for DNA extraction with the QIAamp Fast DNA Tissue Kit, following the manufacturer’s instructions. As genitalia morphology suggested that the adults reared from inflorescences belong to Adainajobimi Vargas, 2020, whose original description was based on specimens reared from inflorescences of Baccharisalinfolia Meyen & Walp. (Asteraceae) (Vargas 2020), DNA was also extracted from two pupae of A.jobimi reared from larvae collected on this plant in the Copaquilla ravine (18°23’55’’S, 69°37’49’’W) at about 2800 m elevation, 12 kilometres south of the study site. Genomic DNA was sent to Macrogen Inc. (Seoul, South Korea) for purification, PCR amplification and sequencing of the barcode region (Hebert et al. 2003) using the primers LCO1490 and HCO2198 (Folmer et al. 1994). The PCR programme was 5 min at 94°C, 35 cycles of 30 s at 94°C, 30 s at 47°C, 1 min at 72°C and a final elongation step of 10 min at 72°C. In order to assess the generic assignment of the plume moths reared from S.philippiana, the sequences obtained were submitted to a Maximum Likelihood (ML) phylogenetic analysis. As shown in Table 1, the alignment included sequences of the type species of the genera of Oidaematophorini represented in the Neotropical Region (Adaina Tutt, 1905, Emmelina Tutt, 1905, Hellinsia Tutt, 1905 and Oidaematophorus) and three outgroup genera of Platyptiliini (Lioptilodes Zimmerman, 1958, Platyptilia Hübner, [1825] and Stenoptilia Hübner, [1825]) downloaded from BOLD (Ratnasingham and Hebert 2007). The restriction of the taxon sampling of Oidaematophorini to the type species of each genus was due to generic definitions being unstable, as evidenced by frequent changes of some species between genera (Gielis 1991, Gielis 2011, Gielis 2014). The software MEGA11 (Tamura et al. 2021) was used to perform sequence alignment with the ClustalW method and to determine genetic distance using the Kimura 2-Parameter (K2P) method. Before the ML analysis, the substitution saturation of the alignment was assessed with the Xia test, using the software DAMBE7 (Xia 2018). The ML analysis was performed with the software IQTREE 1.6.12 (Nguyen et al. 2015) in the web interface W-IQ-TREE (Trifinopoulos et al. 2016). Data were partitioned to codon position. ModelFinder (Kalyaanamoorthy et al. 2017) selected TN+F+I, F81+F+I and HKY+F+R2 as the best-fit models for 1st, 2nd and 3rd partitions, respectively. Branch support was assessed with 1,000 replications of the Shimodaira-Hasegawa-like approximate likelihood ratio test (SH-aLRT, Guindon et al. 2010) and ultrafast bootstrap (UFBoot, Hoang et al. 2017). The unrooted tree was visualised in FigTree (Rambaut 2014) to root on Platyptiliini.

Diagnosis
Oidaematophorusandresi sp. n. can be distinguished from other Neotropical representatives of the genus by the dorsal surface of the fore-wing mostly grey, with a longitudinal yellowish-brown stripe along the anal margin from near the wing base to the complete second lobe. The male genitalia of O.andresi sp. n. resemble those of O.espeletiae, Hernández, Fuentes, Fajardo & Matthews, 2014 from Colombia (Hernández et al. 2014) in having a hooked tip on the apex of the spine of the saccular process of the left valva. However, the dorsal surface of the fore-wing of O.espeletiae is mostly grey at base and mostly cream apically. Furthermore, the saccular process of the left valva is straight along a great part of its length with a short curved portion near the base and the right valva has a single dentate process on the sacculus in the male genitalia of O.andresi sp. n. In contrast, the saccular process of the left valva has a great curved portion and the right valva has two dentate processes on the sacculus in the male genitalia in O.espeletiae. In the female genitalia, the posteriorly wider cup-shaped antrum of O.andresi sp. n. contrasts with the anteriorly wider antrum of O.espeletiae. Furthermore, the antrum of O.andresi sp. n. has an oval-shaped sclerite near the junction with ductus bursae, which is absent in O.espeletiae.
Etymology
The name of the species is dedicated to Dr. Andrés Moreira-Muñoz, for his remarkable contributions to the biogeography and systematics of the Chilean flora.
Distribution
Oidaematophorusandresi sp. n. is known only from the type locality, about 2 km south of Socoroma Village, at about 3400 m elevation on the western slopes of the Andes of northern Chile (Fig. 3).
Biology
The only host plant currently recorded for O.andresi sp. n. is S.philippiana (Fig. 3).
Taxon discussion
Species of Oidaematophorus are recognised by fore-wing venation with R1 absent, R2, R3, R4 and R5 separate, Cu1 from the posterior angle of the discal cell and Cu2 from the discal cell, mid-leg with scale bristles at base of spur pairs and female genitalia with bell- or widened funnel-shaped antrum (Gielis 2011). Ten described species of Oidaematophorus occur in the Neotropical Region (Gielis 2011, Gielis 2014, Hernández et al. 2014, Matthews et al. 2019, Ustjuzhanin et al. 2021b), only one of which, O.pseudotrachyphloeus Gielis, 2011, is known from Chile (Vargas 2021). Although eight species of the genus were recorded from this country earlier (Gielis 1991), these are currently included in Hellinsia (Gielis 2011). Accordingly, O.andresi sp. n. is the second representative of the genus confirmed from Chile. The two species from this country are easily recognised, based on wing pattern, as the fore-wing of O.pseudotrachyphloeus lacks the longitudinal yellowish-brown stripe along the anal margin typical of O.andresi sp. n. The genitalia also provide useful morphological characters in this case, as in O.pseudotrachyphloeus the male has the spine of the saccular process of the left valva strongly curved throughout its length and the female has asymmetrical anterior apophyses and ductus seminalis only slightly longer than the corpus bursae, in clear contrast to O.andresi sp. n. Although the host plant ranges of these two species must be explored further, the currently available records suggest that they use different host plants, because O.pseudotrachyphloeus has been reared only from Ambrosiacumanensis Kunth (Asteraceae) (Vargas 2021).

Taxon discussion
Host plant records available for Adaina indicate that a single species may be able to feed on several Asteraceae belonging to one or more genera (Landry and Gielis 1992, Matthews and Lott 2005). Baccharisalnifolia Meyen & Walp. (Asteraceae) was the only host plant previously known for A.jobimi (Vargas 2020). Accordingly, rearing from S.philippiana adds a new host plant record and suggests that this plume moth is able to use distantly-related members of Asteraceae. As this plant family is well represented in the study area (Moreira-Muñoz et al. 2016), further surveys would be needed to know the complete host plant range of A.jobimi.
Analysis
Four identical DNA barcode sequences were obtained from the pupae of A.jobimi reared from larvae collected on S.philippiana (GenBank accessions OP281683, OP281684) and B.alnifolia (OP281685, OP281686), confirming the morphological identification. Two DNA barcode sequences (OP281687, OP281688) with 0.3% (K2P) distance between them were obtained from the adults of O.andresi sp. n. The alignment of ten sequences of 657 bp length was suitable for phylogenetic analysis, as no evidence of stop codons or substitution saturation (ISS < ISS.C; p < 0.001) was detected. The sequences of the two species were clustered with the type species of their respective genus, Adainamicrodactyla (Hübner, [1813]) and Oidaematophoruslithodactyla (Treitschke, 1833), in the ML tree (Fig. 4). Genetic distance was 9.6% between A.jobimi and A.microdactyla and 10.9–11.0% between O.andresi sp. n. and O.lithodactyla.
Discussion
Asteraceae is one of the main host families of Pterophoridae and even a single species of this plant family can support multiple lineages of plume moths (Matthews and Lott 2005). In the present study, surveys for lepidopteran larvae on the endemic S.philippiana in the Andes of northern Chile enabled the rearing of two species of the tribe Oidaematophorini, A.jobimi and O.andresi sp. n. This discovery highlights the importance of surveys on native plants to improve the knowledge of the micromoth diversity of the arid environments of the central Andes. As this study was restricted to the northern of the two disjunct areas inhabited by S.philippiana, further surveys in the southern part of its range would be helpful to assess if the two species collected in the highlands of the Andes are also found in the lowlands of the Atacama Desert.
Generic assignment for a given plume moth species can be a difficult task when it involves some morphologically similar genera of Oidaematophorini, as shown by several species that have moved amongst Adaina, Hellinsia and Oidaematophorus (Gielis 1991, Gielis 2003, Gielis 2011). Phylogenetic analysis of mitochondrial DNA sequences provides a valuable tool in cases like these, as shown in several families of Lepidoptera (e.g. Moreira et al. 2012, Corley et al. 2020, San Blas et al. 2021). In the present study, in agreement with morphology, the result of the phylogenetic analysis provides support for the generic assignment of the two species of Oidaematophorini reared from S.philippiana, because each grouped with the type species of its respective genus. However, a clade must have at least 80% SH-aLRT and 95% UFBoot support to be reliable (Minh et al. 2022). Although the SH-aLRT support values for Adaina and Oidaematophorus are higher than 80%, those of UFBoot are lower than 95%. Accordingly, further phylogenetic analysis, based on wider taxon sampling and additional molecular markers, would be useful to understand better the evolutionary relationships of Neotropical Oidaematophorini and to provide support for delimitation of its genera.
The knowledge of the Neotropical fauna of plume moths has significantly improved in the last thirty years (Gielis 1991, Gielis 2006, Gielis 2011) and recent contributions suggest that many environments of this region harbour additional undiscovered species (Ustjuzhanin et al. 2021a, Ustjuzhanin et al. 2021b, Ustjuzhanin et al. 2021c). As shown in several studies, surveys for adults and immature stages are fundamental to continue the improvement of the understanding of systematics, geographic ranges and host plant use of the plume moths of a given geographic area (Landry and Gielis 1992, Landry 1993,Landry et al. 2004, Matthews et al. 2012, Matthews et al. 2019). Accordingly, field work in under-explored environments should be encouraged to understand better the highly diverse Neotropical fauna of plume moths.
