TL;DR: A collection of 448 Odonata specimens made on Pohnpei, Caroline Islands, Micronesia, in 2001–2002 allows a reassessment of the fauna of this small, isolated island, and all of the odonate species seem secure at this time, although T. nigrolutea appears to be less common now than in the past.
Abstract: A collection of 448 Odonata specimens made on Pohnpei, Caroline Islands, Micronesia, in 2001–2002 allows a reassessment of the fauna of this small, isolated island. There are 15 species, including six species of the zygopteran genus Teinobasis, which apparently speciated in situ, an unusually great diversity for such a small island. One of these species was undescribed. A revised key to the Teinobasis of Pohnpei is included, the larvae of three species of Teinobasis are compared, and the females of T. aerides and Pacificothemis esakii are described for the first time. The three odonate species represented by adequate series, T. ariel, T.fortis, and Hemicordulia haluco, appear to increase in body size with elevation. The island still has all of its natural habitats, although native upland forests continue to decrease as more land is cleared for agriculture. All of the odonate species seem secure at this time, although T. nigrolutea appears to be less common now than in the past.

TL;DR: The odonate fauna of Kosrae, Micronesia appears to have remained stable with no known extinctions or colonizations over the past half century, and it comprises six widespread weedy species and one endemic, Hemicordulia erico.
Abstract: A recent collection of 69 specimens together with survey counts and incidental observations during June–July 2002 provide new information on the odonate fauna of Kosrae, Micronesia. The fauna comprises one zygopteran (Ischnura aurora) and six anisopterans. It appears to have remained stable with no known extinctions or colonizations over the past half century. The fauna is nearly a subset of that of Pohnpei and the islands to the west, and it comprises six widespread weedy species and one endemic, Hemicordulia erico. Upland aquatic habitats appear largely unexploited or underutilized by odonates, and the absence of any Teinobasis species on Kosrae is in marked contrast to the presence of six species on the nearest high island, Pohnpei.

TL;DR: Keys are given to both sexes of all named species from the genus known from peninsular Malaysia, Singapore and the Greater Sunda Islands and the species are placed provisionally into two groups: the laidlawi-group and ruficollis-group.
Abstract: Teinobasis cryptica sp. nov. (holotype ♂: Borneo, Sarawak, Bahagian Samarahan, Kota Samarahan, old UNIMAS campus, disturbed peatswamp forest, 25 ii 2008, RMNH) from Malaysia is described from both sexes and compared with other Teinobasis species known to occur in Malaysia. The members of the genus known from Sundaland are reviewed. Records of T. ruficollis from Borneo are clarified. New records of other Bornean species are listed. The females of T. laidlawi, T. rajah and T. ruficollis are described for the first time. Keys are given to both sexes of all named species from the genus known from peninsular Malaysia, Singapore and the Greater Sunda Islands and the species are placed provisionally into two groups: the laidlawi-group and ruficollis-group. The former group also includes T. rubricauda from the Palawan region of the Philipplnes, which may be a junior synonym of T. laidlawi.

TL;DR: The new species belongs in the Fortis-group and differs from all species in that group by characters of the male appendages, female ovipositor, hind prothoracic lobe, and coloration of immatures.
Abstract: Teinobasis budeni sp. nov. is described from Pohnpei, Federated States of Micronesia. Holotype ♂: Micronesia, Pohnpei, Sokehs, Nanpil River headwaters, 01 July 2001; allotype ♀: same locality, 03 February 2001, both leg. D.W. Buden; to be deposited in FSCA, Gainesville, FL, USA. The new species belongs in the Fortis-group and differs from all species in that group by characters of the male appendages, female ovipositor, hind prothoracic lobe, and coloration of immatures.

TL;DR: Papuagrion is derived from a Papuan radiation of the genus Teinobasis, members of which inhabit standing or slow-flowing and often muddy waters, where the larvae probably develop, suggesting that the colonisation of phytotelmata offered by Pandanus trees has led to the radiation of PapuagRion.
Abstract: The larva of Papuagrion is described and illustrated for the first time based on two specimens collected near Goroka, Papua New Guinea. The larvae were identified by matching the mitochondrial marker COI with that of an adult specimen collected at the same locality. The larvae were found in the leaf axils of Pandanus trees which agrees with earlier observations that adults are often encountered away from water, in the vicinity of Pandanus. Larvae collected from water pooled in the leaf bracts of several Pandanus trees in the Muller Range (PNG) are also thought to belong to the genus Papuagrion. Based on these records and further observations it is considered likely that all species of Papuagrion live in phytotelmata and that most or even all are found in Pandanus trees. Papuagrion is derived from a Papuan radiation of the genus Teinobasis, members of which inhabit standing or slow-flowing and often muddy waters, where the larvae probably develop, suggesting that the colonisation of phytotelmata offered by...
