   DOI:  10.11646/zootaxa.4555.1.2 

Abstract

Euphaea cyanopogon sp. nov. is described and illustrated from specimens of both sexes collected in the Kampongsaom Peninsula in southern Cambodia and the adjacent Phú Quốc Island in Vietnam, both in the Cardamom ecoregion; the holotype ♂ (at RMNH, Leiden) is from Kbal Chhay Waterfall, Cambodia. The male is characterized by having rather narrow wings without areas of strong pigmentation and a face marked with bright blue. The differences and affinities of the new species with E. pahyapi Hämäläinen, 1985 and some of its other congeners are discussed.

Keywords: Odonata, damselfly, Zygoptera, Euphaea, new species, Cambodia, Vietnam, Indochina, Cardamom ecoregion

Euphaea cyanopogon sp. nov.

Euphaea ochracea, nec (Selys, 1859)

Euphaea pahyapi, nec (Hämäläinen, 1985)

Etymology. The specific epithet, a noun in apposition, is a composite of Latinised forms of two Greek words κυάνεοs: dark blue and πώγων: beard, together meaning ‘blue beard’, referring to the coloration of the lower face in males of the new species.

[Entomology • 2018] Amphicnemis valentini • A New Species of Damselfly (Odonata: Coenagrionidae) from the Cardamom Ecoregion in Cambodia and Vietnam

Amphicnemis valentini

DOI:  10.11646/zootaxa.4429.2.4 

Abstract
Amphicnemis valentini sp. nov. is described from the Ream Peninsula of Cambodia (holotype: Cambodia, Preah Sihanouk Province, Ream Peninsula, 10.52258 N 103.69556 E, RMNH) and Phú Quốc Island, Kien Giang Province of Vietnam, both in the Cardamom ecoregion. It is similar to A. gracilis Krüger, 1898, which occurs in Peninsular Malaysia and Sumatra, but differs from it by a long process on the male prothorax.

[Entomology • 2017] Lyriothemis kameliyae spec. nov. • The Riddle of Lyriothemis bivittata (Rambur, 1842) (Odonata: Libellulidae)

DOI:  10.11646/zootaxa.4250.4.2 

Abstract

Lyriothemis kameliyae spec. nov. from northern Vietnam is described and illustrated for both sexes, and descriptions are given of male and female specimens of L. bivittata collected in Vietnam. A comparison of their distinguishing characteristics is provided, and differences from similar L. tricolor are discussed. Earlier descriptions and some records of L. bivittata are evaluated. Evidently these contain at least some L. kameliyae specimens, and therefore historic records of L. bivittata require evaluation. The ranges of the two species overlap considerably. Some information is provided on the biology of L. kameliyae.

Keywords: Odonata, Libellulidae, Lyriothemis kameliyae spec. nov., new species, Vietnam

 Lyriothemis kameliyae spec. nov.

Etymology. The species is named after Kameliya Petrova in gratitude for her assistance with my book “Dragonflies and Damselflies of the Serra dos Orgaos” and unrelenting support for my continuing research on Odonata in Vietnam. Kameliyae, a noun in the genitive case.
