039DB9326229FF807C66F9065838FA3D.taxon	description	Variation in male paratypes In some of the paratypes the thin thoracic middorsal stripe is connected to the thin antehumeral stripe; the “ W ” - shaped spot on the venter of the pterothorax varies, with some forming a “ U ” and others being parenthesis-shaped “ () ” (Figs 2 A, B). Sometimes the abdominal lateroapical stripe extends to S 4, sometimes there is a proximal spot on S 5. The wing’s white stripe exhibits variation in width and in the starting and ending points within it (Table 1, Fig. 5 A). Measurements. Total length 5.2 – 5.5 cm, abdomen 4.2 – 4.5 cm (Fig. 3 A), right wings see Table 1. Allotype description and variation in female paratypes Head. Anteclypeus similar to that of holotype, almost black. Legs as in the holotype. Thorax and abdomen. Body coloration as in the holotype (Figs 1 B, C), but the lateral stripe on the abdomen starts in S 1 and terminates in the distal quarter of S 5. The ventral coloration of the thorax varies from as in the holotype to a “ U ” - shaped spot (Fig. 2 C). Ovipositor almost black, with a series of small denticles ventrally. Ovipositor stylus tip is the most distal part of the body (Fig. 7). Wings. The pale band is variable in size and some females have hyaline wings (Figs 3 B, C, 4 B, 5 B). Measurements. Total length 4.9 – 5.3 cm, abdomen 3.9 – 4 cm, right wings see Table 1.	en	Bota-Sierra, Cornelio, Herrera, Melissa Sánchez (2023): A new species of bannerwing damselfly, Polythore albistriata sp. nov. (Odonata: Polythoridae). International Journal of Odonatology 26: 82-92, DOI: 10.48156/1388.2023.1917037, URL: https://doi.org/10.48156/1388.2023.1917037
039DB9326229FF807C66F9065838FA3D.taxon	diagnosis	Diagnosis Bick & Bick (1985, 1986) proposed six groups within the genus based mostly on their wing colorations, but the latest phylogenetic hypotheses show that these groups are not natural (Sánchez et al., 2018, 2020). They (Fig. 3) recovered P. albistriata sp. nov. (as Polythore sp. nov.) as closely related to P. conccina and P. procera. Males of these three species can be identified by their strongly contrasting wing coloration: Polythore concinna has smoky amber wings (Fig. 8 A), P. procera has a white band in its middle third followed by a black band in the distal area (Fig. 8 A), while P. albistriata has a white band in the middle third only (Figs 4, 5). Also, the shape of the genital ligula differs between these species: Polythore concinna has two very distinctive, enlarged processes on the apex, while P. procera and P. albistriata have similar ligula that can be differentiated by the apical lobes being more elongated in P. procera than in P. albistriata, and the lateral flagella in P. procera are two-segmented while in P. albistriata the apices of the flagella are thickened but not segmented into two (Figs 8 B, 6). The females can be distinguished by the color of their wings: Polythore concinna has amber-brown bands, P. procera sometimes shows a white band, but it is always followed by a black band that varies in size (Fig. 8 A), sometimes being very narrow and sometimes covering the entire apex of the wing, while P. albistriata may sport a white band or have totally hyaline wings (Figs 3, 8 A). The species P. williamsoni and P. mutata have similar wing colorations as P. albistriata, with transverse white bands, but they differ in their genital ligula. The ligula of P. mutata has angulate anterolateral lobes, extremely short flagella, and wider lateroapical processes than P. albistriata, while P. williamsoni has ear-shaped two-segmented, long lateral flagella and wider lateroapical processes as well (Sánchez et al., 2018). In addition, the geographical distributions of these two species are completely disjunctive from P. albistriata; P. mutata is mainly distributed in the Amazon foothills, and P. williamsoni in the southeastern Andes of Peru. DNA barcode identification Two mitochondrial gene sequences that belong to Polythore albistriata sp. nov. were previously published on NCBI GenBank (see Table 2 for Accession Numbers). In addition, the Minimum Spanning Networks reveal that the haplotypes of P. albistriata are divergent from the most closely related species (Fig. 9). However, it is important to highlight that the COI is highly diverse across all sampled haplotypes for all the species we compared. There may be more mutations between two specimens of P. albistriata coming from different geographic populations (18 mutational steps) than between some of the specimens from other species that are geographically closer to them (e. g., 6, 28 or 38 mutational steps between P. procera vs. P. albistriata haplotypes; see Fig. 8), suggesting that this gene fragment might be affected by introgression across close geographic populations, possibly indicating recent gene flow or incomplete lineage sorting across these species. The ND 1 locus seems more stable at species level, clearly merging all the haplotypes of P. albistriata and showing divergence from the haplotypes of P. concinna, P. procera and P. derivata (Fig. 9). Based on our results we suggest that for DNA identification in this genus NADH subunit I Dehydrogenase is a better barcode at species level, while Cytochrome Oxidase I can be a useful barcode for population-level signatures within a narrow geographical range.	en	Bota-Sierra, Cornelio, Herrera, Melissa Sánchez (2023): A new species of bannerwing damselfly, Polythore albistriata sp. nov.

039DB9326229FF807C66F9065838FA3D.taxon	distribution	Distribution This mew species occurs in the southeastern Colombi- an Andes between 1,500 and 2,300 m a. s. l .. It has been recorded mainly in the upper Magdalena Valley in both the Central and Eastern Cordilleras (Huila Department) and in some localities on the Amazon slope of the Eastern Cordillera (Caquetá and Putumayo Departments; Fig. 10). This distribution pattern concurs with the biogeographic limits determined by the Colombian Massif and the Las Cruces Pass found in a study on endemic Andean birds (Hazi et al., 2018).	en	Bota-Sierra, Cornelio, Herrera, Melissa Sánchez (2023): A new species of bannerwing damselfly, Polythore albistriata sp. nov.
