Damselflies of the genus Lestes Leach, 1815 are represented in India by 11 species. Using specimens collected over the last five years, we report on the rediscovery of Lestes nigriceps in India after 98 years, at two new localities in the Western Ghats. This species was observed at the Aarey Milk Colony, Mumbai, and in the Sindhudurg District, Maharashtra, India. The diagnosis of the subspecies Lestes patricia taamrpatti Bhakare, Bhoite & Pawar, 2020 is re-assessed, found insufficient for differentiation, and this taxon is synonymized with Lestes patricia Fraser, 1924, as a consequence. We present an updated key to the species of Lestes of the Western Ghats biodiversity hotspot.

Natural landscapes of Latin America, such as the Cerrado biome, are increasingly changing due to conflicting development models between economic growth and biodiversity conservation. In cases of total or partial suppression of natural vegetation, more sunlight reaches the streams, leading to changes in Odonata assemblages. Due to their thermoregulation characteristics, the proportion of the suborder Anisoptera tends to increase whereas the suborder Zygoptera will decrease, as this suborder is more sensitive to habitat loss. We assessed whether the proportions of individuals and species richness of Zygoptera and Anisoptera changed due to environmental quality loss in Cerrado stream habitats. Also, we assessed the performance of ratios using genus and family level. We conducted our study at 18 streams in Mato Grosso State, Brazil. We sampled Odonata communities and measured the environmental quality of each stream using the Habitat Integrity Index. To assess the relationship between the environmental quality of the streams and the Odonata ratios, we performed generalized linear models with the beta distribution family. The models showed that the loss of environmental integrity caused Zygoptera to decrease and Anisoptera to increase. In addition, we found that Acanthagrion/Zygoptera and Argia/Zygoptera ratios showed a strong relationship with habitat integrity, being plausible alternatives for use in monitoring programs. We conclude that the Zygoptera/Anisoptera ratio is a good indicator of environmental quality for the Cerrado biome and therefore makes for a suitable tool for citizen science programs in which no taxonomic expertise is required.

A note on the rare dragonfly Davidioides martini Fraser, 1924, is provided with an update of its distribution range, status, ecology, and the description of its so far unknown female. This species is endemic to the Western Ghats of Peninsular India and seems to be a rare one as is indicated by the paucity of published records, some of which are shown to be doubtful and in need of corroboration.

The final instar larva of Cordulegaster kalkmani Schneider, Vierstraete, Müller, van Pelt, Caspers, Ikemeyer, Snegovaya & Dumont 2021 is described and illustrated based on one female exuvia collected in Alakabük, Bitlis province, Turkey, in July 2022. The exuvia of Cordulegaster kalkmani is compared with the exuviae of members of the “boltonii group” in the eastern part of the Western Palaearctic: C. vanbrinkae, C. picta, and C. heros. The exuvia of C. kalkmani shows no clear distinction in comparison to the other members of the eastern “boltonii group”.

Diaphlebia richteri is shown to be a junior synonym of Zonophora nobilis. The confusion started by a generic misplacement due to the failure to observe the subalar carina spine which is present in Zonophora but not in Diaphlebia. Therefore, Z. nobilis is officially recorded for the first time in Colombia; we present a distribution map with the known localities for this rare Amazon species. Also, we made a comparison between our female specimens and the original description of the female from Cerro de la Neblina (Venezuela), including the first photographs of diagnostic characters of a female specimen.

A new species of Protosticta Selys, 1885 is described based on specimens collected from Kerala, northeast of Thiruvananthapuram, in the southern parts of the southern Western Ghats of India. Protosticta armageddonia sp. nov. is compared with all other known Protosticta species of the Western Ghats to provide comprehensive differential diagnosis. The new species is distinguished from its congeners by a combination of characters, including a marking on the ventral side of thorax, structure and colour of the prothorax, markings on the 8th abdominal segment, and the structure of caudal appendages and genital ligula. Furthermore, we provide preliminary information on the ecology and natural history of the new species.

The traditional method of classifying the twenty-one species within the South American genus Polythore has been relying on wing color patterns and male genital ligula shape. However, recent molecular research has shown that wing color patterns can vary significantly within some species, making it an insufficient means of species diagnosis by itself in some cases. In this study, we employ a combined approach of morphological and molecular data to describe a new Polythore species found in the southeastern Colombian Andes. Our analysis includes detailed illustrations and pictures of diagnostic features, haplotype networks for two barcode genes, COX1 and NADH I, a distribution map, and a brief discussion of the conservation status of the species. We found wing color pattern, male genital ligula morphology, and NADH I barcode sequences to be sufficiently diagnostic to identify the species as new. Our results highlight the importance of integrating multiple data sources for accurate species identifications and descriptions in this genus.

Although Ischnura aurora (Brauer, 1865) was traditionally considered to be widely distributed in Asia, the populations west of continental China have recently been identified as equivalent to Ischnura rubilio Selys, 1876. While the Taiwanese population has long been regarded as I. aurora as well, Taiwan in fact represents the distribution boundary between I. aurora and I. rubilio. Based on molecular and morphological analyses, we confirm that the “I. aurora-like” damselfly in Taiwan corresponds to I. rubilio. It is noteworthy that the abdominal blue spots of males in the Taiwan population have a unique phenotype compared to those found in specimens from India and continental China. According to past references and current surveys, the I. rubilio population in Taiwan has critically declined, with only one confirmed locality currently remaining. To maintain the Taiwanese population of I. rubilio, we recommend that prompt conservation measures of the habitat be implemented, focusing on the concept of the Satoyama Initiative.

Tukanobasis huamantincoae sp. n. (holotype ♂: Peru, Loreto Región [MUSM]) is described and illustrated. Males of T. huamantincoae can be distinguished from T. corbeti by the presence of postocular spots and antehumeral stripes, the absence of apical brown wingspots, smaller number of postnodals, shorter CuA, vein descending from quadrangle not forming straight line to wing margin, pterostigma in HW distally distinctly yellow, S8–10 orange/red, cerci more strongly curved and with apical blunt appendix, genital ligula with triangular lateral lobes and overall smaller body dimensions. With the description of this second species of Tukanobasis it becomes clear that some characters previously attributed to the genus are species-specific, requiring an updated generic characterization.
