Use of the Zygoptera/Anisoptera Ratio (Insecta: Odonata) for Habitat Alteration Assessment in Cerrado Streams

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.

Taxonomic notes on Davidioides martini Fraser, 1924 (Odonata: Gomphidae) and description of its female from Western Ghats, Peninsular India

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.

Description of last instar larva of Cordulegaster kalkmani (Odonata: Cordulegastridae)

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.

Diaphlebia richteri Bota-Sierra, 2015 is a junior synonym of Zonophora nobilis Belle, 1983 (Gomphidae: Odonata)

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.

Description of Protosticta armageddonia sp. nov. (Odonata: Zygoptera: Platystictidae) from the Western Ghats of India

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.

A new species of bannerwing damselfly, Polythore albistriata sp. nov. (Odonata: Polythoridae)

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.

Philogenia realpei sp. nov. (Zygoptera: Philogeniidae), a new damselfly species from Colombia

A new damselfly species, Philogenia realpei sp. nov., is described here from 5 ♂♂, 2 ♀♀ collected at Cauca and Putumayo departments in southern Colombia. This species is included in the P. helena group and can be differentiated from other species by the unique morphology of its paraprocts.

Molecular phylogenetic analysis and its impact on the conservation of Ischnura rubilio Selys, 1876 (Odonata: Coenagrionidae) in Taiwan

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.

Tukanobasis huamantincoae, a new species of damselfly from Peru (Odonata: Coenagrionidae), with updated generic characterization

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, …

Morphological and molecular evidence supports the species status of the Italian endemic Coenagrion castellani Roberts, 1948 (Coenagrionidae)

Coenagrion castellani Roberts, 1948 was described from Italy as a distinct species almost 75 years ago but has generally not been recognised or was treated as a subspecies of C. mercuriale (Charpentier, 1840). Populations south of the Alps were recently shown to be completely isolated genetically from those in North Africa and elsewhere in Europe.
