E-mail: [email protected] Abstract Four new species and one new subspecies of Arctiinae (Lepidoptera: Erebidae) are described. Aphyle niedmandi sp. nov., Evius ocassus sp. nov., Paranerita maculata sandeepani ssp. nov., Paranerita kotolnuki sp. nov. and Baritius flexuosus sp. nov. were collected in the Tambopata River region, Madre de Dios (Peru), as part of a Citizen Science Project, in mu- tual collaboration between the Natural History Museum (Lima–Peru) and Rainforest Expeditions. External morphological descriptions, morphology of male genitalia, and geographic distributions in Peru are given for all taxa as well as their barcoding. Key words: citizen science, Neotropical, Phaegopterina, taxonomy Introduction Advances in the last decades in the knowledge of Neotropical Arctiinae are based on phylogeny studies (Jacobson & Weller 2002; Zaspel et al. 2014; Zenker et al. 2017), revisions of some genera (Dietz & Duckworth 1976; Dietz 1994; Simmons & Weller 2006; Pinheiro & Duarte 2010; Pinheiro & Mey 2015), morphological studies (Weller et al. 2000), faunistic studies (e.g., Grados 1999, 2001; Piñas et al. 2000; Piñas & Manzano 2003; Teston & Corseuil 2004; Cerda 2008; Teston & Ferro 2016), new species descriptions (e.g., Grados 2004, 2015; Vincent 2011, Vincent et al. 2014; Coenen & Gibeaux 2014; Pinheiro 2016) and the publication of some synonyms (e.g., Grados 2002; Pinheiro & Duarte 2013; Beccacece & Zapata 2017). Systematists have always faced a great problem to correctly identify species. In the case of Arctiinae, these are partly related to the lack of sufficient material to study and to analyze in depth the traits that delimit species. It is possible to mention that at present, after 250 years of the initiation of systematists work at the world level (Linnaeus 1758; ICNZ 1999), in many species only the type specimen or the type series specimens are known. This lack of material has become more critical in the last decades, due to the innumerable demands and documents that the different governments request to make collections of biological specimens for scientific research purposes, including the loan of material among institutions dedicated to research, without getting into details on the total restrictions that some countries have. Estimates on the number of species that inhabit the planet vary depending on the authors and what groups they work on. The more conservative estimates indicate that there would be more than 5 million species (Wilson 1988; Stork 1993). With the current rate of new species descriptions, the estimate of having more than 1,500 systematic specialists worldwide and the need to have 25,000 full–time professionals to fully know the diversity of the planet, considering also that actually there is a global level reduction of resources in the formation of taxonomists, which requires years of preparation and specialization, entering the whirlpool without exit of the need, yet in turn, no investment, getting to extents such as that in many museums of the world, curators, are barely supplied for their basic tasks, the taxonomy crisis is evident, some having called this the "taxonomic impediment" to get to know the true biodiversity of the planet (Wilson 1988, Mallet & Willmott 2003, Wheeler et al. 2004, Agnarsson & Kuntner 2007). Against this background, the use of the sequencing a small 600–base pair fragment of a gene, the Accepted by L. Pinheiro: 4 May 2018; published: 14 Jun. 2018 29 Licensed under a Creative Commons Attribution License http://creativecommons.org/licenses/by/3.0 Cytochrome Oxidase subunit 1 (COI) known as "barcoding", has been proposed as a molecular universal alternative for solving the taxonomic identification problem for the rapidity, low cost and reliability, and that in the future it could replace the experience and knowledge of the traditional systematic (Hebert et al. 2003). However, some critiques have been swift to show up (Mallet & Willmott 2003), due to the limitations it presents in view of the results obtained (Rubinoff et al. 2006; Meier et al. 2006; Johnsen et al. 2010). We can mention one of the emblematic cases in Lepidoptera. The species Astraptes fulgerator has been considered as a single one, variable and with broad geographic distribution: from the southern United States to northern Argentina. By means of barcoding studies it has been proposed that it would actually be a set of 10 cryptic species (Hebert et al. 2004). However in the same study, the authors point out that with the information they have about host plants, larval coloring pattern and adult phenotype, Astraptes fulgerator would actually be composed of a complex of six or seven species. Just a controversial position is provided by Brower (2006), in relation to the molecular approach of Hebert et al. (2004). By reanalyzing the data obtained and proposing that it would be seven species instead of ten. In another study of the Ithomiinae (Nymphalidae) butterfly community of the tropical forest in Ecuador (Elias et al. 2007) it has been shown that barcoding success in species identification barely reached 77%. More and more work mentions that reliability in species identification through barcoding has serious limitations. This implies that DNA barcoding only cannot support the diagnosis of valid species, being essential to find other characters, either morphological at different stages in insects (Yassin et al. 2010), ecological, ethological or biogeographic (Dayrat 2005; Rubinoffet al. 2006; Burn et al. 2008; Yassin et al. 2010; Whinnett et al. 2005). For these reasons, I have used barcoding as one in set tools for diagnosing new species (Mallet & Willmot 2003) and not as a unique and irreplaceable tool. On the other hand, it is necessary to point out the existence of complexes of species, which have a very similar external morphology and, after doing taxonomic revisions, with studies of genitalia, have revealed the existence of complexes with greater number of species than what was known. In fact, in several of these groups, where reviews have not been carried out, mainly due to the lack of specialists, is where barcoding analysis has led to the revision and confirmation of a greater number of species. This implies that barcoding can become an alert tool for taxonomic revisions in species complexes and, in cases of twin species, to find the characters that differentiate species (De Salle 2006; Burns et al. 2008; Beccacece & Vincent 2014). It has been 14 years since Hebert et al. (2003) proposed that the COI database could be developed for the 5–10 million species of animals. For now, the information gaps are huge. The identification of species based on barcoding is limited, in addition to the factors pointed out by Rubinoff et al. (2006) and several others, by the existence of the sequencing in the database. If the sequencing does not exist, identification is not feasible and much less it is adventuring to claim that it would be an unknown species. Another important factor is who identifies the species, since the database is the starting point for other users to take this as a reference. Just as in the morphological systematics, it is essential and necessary in order to have objectivity, to review the primary sources, that is, to analyze the types. In the same way the barcode would need to be nourished from the same sources. The usefulness of the databases will increase to the extent that they are more complete for the respective groups to be analyzed. In this work, for each species is provided a diagnosis, external morphological descriptions, internal anatomy characters of males genitalia, geographic distributions and the sequencing of the mitochondrial gene, Cytochrome C Oxidase subunit 1 (COI). Materials and methods The descriptions of the four new species and one new subspecies are the result of daily collections at Refugio Amazonas Lodge (ARA), located at the right bank of the Tambopata River (Madre de Dios, Peru), as part of a Citizen Science program, whom direct participants were guests of the Lodge, with the mutual collaboration between the Natural History Museum (MUSM) and the company Rainforest Expeditions. A light trap with a mixed light bulb of 250 V was used to capture the specimens. The samples were sacrificed using a butyl acetate lethal jar, and were processed at the Museo de Historia Natural, Universidad Nacional Mayor de San Marcos. The sequencing of the mitochondrial gene, Cytochrome C Oxidase subunit 1 (COI), was carried out in the Biodiversity Institute of Ontario, University of Guelph, according to the protocol described in Vaglia et al. (2008). All samples (tissue from right hind legs) submitted for sequencing were from Tambopata River (Madre de Dios, Peru). The 30 · Zootaxa 4434 (1) © 2018 Magnolia Press GRADOS distance was calculated using MEGA7 (Kumar et al. 2015), using Kimura 2-parameter model. The abdomens and genitalia of the male specimens were dissected and prepared using hot KOH solution (10%). Photographs of adults were taken with a Nikon D80 and the photographs of the genitalia with a Canon EOS Rebel T6. The entomological collections revised for the elaboration of this work were: (MUSM) Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima, Peru; (NHMUK) Natural History Museum, London, United Kingdom; (USNM) United States National Museum, Smithsonian Institution, USA. All specimens have been deposited in the Museo de Historia Natural, Universidad Nacional Mayor de San Marcos (MUSM). Wing venation terminology follows Comstock & Needham (1898, 1899), Miller (1970) & Common (1990). Genitalia terminology follows Sibatani et al. (1954), Kuznetsov (1967) and Klots (1970).

The new species has a color pattern and external morphology similar to A. cuneata, differing from it in the black spots on the wing base: The spot at very base of the wing and the largest proximal patch are continuos in A. cuneate, while in A. niedmandi are discontinuous, with tiny spots. The genitalia morphology is very similar in both species; the most notorious differences are in the antennae and eighth tergite and sternite. Antennae are bipectinated in both taxa, but the rami have almost the same length of the shaft in A. cuneata, giving it a pentagonal shape (Fig. 15), while in A. niedmandi they are shorter, so the flagellomeres are rectangular shaped (Fig. 16). The eighth tergite of A. cuneata has large lateral apodemes, one quarter the length of the entire tergite (Fig. 11). FOUR NEW SPECIES AND ONE NEW SUBSPECIES FROM PERU. Zootaxa 4434 (1) © 2018 Magnolia Press · 33 In A. niedmandi the tergite is wider, and the apodemes are small (Fig. 12). In the eighth sternite, the apodeme of A. cuneata is broad and has lateral extensions (Fig. 13), whereas in A. niedmandi the apodeme is narrow and continuous along the anterior border (Fig. 14). Aphyle cuneata occurs in Guyana, French Guiana (MHNP), Ecuador (Piñas et al. 2000), and Peru. For the latter country, there are records from the departments of Loreto, Cusco and Madre de Dios. Aphyle niedmandi, on its turn, has been recorded from Loreto, Ucayali, Junín, Cusco and Madre de Dios. The genetic distance between both species is 5.52%. FIGURES 11–16.

The new species differs from it in the reddish brown spot on the junction of R 4 and R, going up to the middle area of cell R-M , which is not observed in E. roseosimulans. Both species also 5 5 1 differ in the genitalia, where the proportion of the sizes of ventral and dorsal processes of the valvae. While in E. roseosimulans the dorsal process is less than double the size of the ventral one, in Evius ocassus n. sp. the dorsal process is three times that of the ventral. Another species resembling E. ocassus is E. cochenouri Schaus, 1910, described from Juan Viñas, El Sitio (Costa Rica). This species is easy to tell apart from E. ocassus because E. cochenouri has yellow patagia, while they are reddish yellow; in E. cochenouri has a reddish brown area not reaching tornus of forewings, whereas in E. ocassus it does.
