On the subfamily Cypricercinae McKenzie, 1971 (Crustacea, Ostracoda) from Thailand, with the description of six new species

Abstract

Species of the subfamily Cypricercinae collected from Thailand, mainly from the Northern Provinces, are here reported and/or (re-) described. Nineteen species, belonging to seven genera were found. Six new species, Strandesia hornei sp. nov., Strandesia sanoamuangae sp. nov., Pseudostrandesia gaetani sp. nov., Pseudostrandesia ovata sp. nov., Pseudostrandesia phetchabunensis sp. nov. and Pseudostrandesia thailandensis sp. nov., are described. A species list of the Cypricercinae in Southeast Asia is given and the general distribution and ecology of the Cypricercinae from Thailand is briefly discussed.

Re-description of Strandesia sanoamuangae Savatenalinton & Martens, 2010 and description of a new species of Strandesia (Crustacea, Ostracoda) from Grande Terre, New Caledonia

“…This species resembles Strandesia mehesi sp. nov. from New Caledonia, but it is more elongated, with a long straight part of the dorsal margin (rounded in the new species) and also does not show a trace of the anterior selvage in the RV which is present in the specimens from New Caledonia (see redescription in Savatenalinton & Martens, 2010). Several other species resemble S. mehesi sp.…”

“…The present populations from New Caledonia have been identified as Strandesia sanoamuangae (Savatenalinton & Martens, 2010) from Thailand, because of the strong resemblance in shape and ornamentation of the carapace. There are some small morphological differences in the New Caledonian populations: the carapace is slightly less arched in the dorsal and ventral views at its greatest width; its sinuous protrusion in the ventral view is slightly anterior to the greatest carapace width; the LV overlap of the RV is slightly narrower, and the periphery of the LV is inconspicuous at the dorsal margin in the right lateral view.…”

“…Strandesia sanoamuangae also somewhat resembles Strandesia perakensis (Victor & Fernando, 1981), but the carapace of this latter species lacks tubercles and is set with long sensilla and spines. The small pits on its Cp are also markedly visible from the inner view of the valves (see illustrations in Victor & Fernando 1981 and the re-description in Savatenalinton & Martens 2010).…”

“…The present paper reports on two species of freshwater Ostracoda from Grande Terre, New Caledonia. It provides the re-description of Strandesia sanoamuangae Savatenalinton & Martens, 2010 and the description of Strandesia mehesi sp. nov. both from female-only populations.…”
