The Collothecidae (Rotifera, Collothecacea) of Thailand, with the description of a new species and an illustrated key to the Southeast Asian fauna.

Meksuwan P, Pholpunthin P, Segers H - Zookeys (2013)

Bottom Line: A total of 13 species, including two additional infraspecific variants, of Collothecidae are recorded, one of which is described as a new species of Collotheca.We further add taxonomic remarks on some of the taxa on record and illustrate the uncinate trophi of several representatives by scanning electron microscopic images.Finally, we provide illustrated identification keys to the Collothecidae recorded to date from Southeast Asia.

ABSTRACT
Following previous reports indicating a remarkable high diversity of sessile rotifers in Southeast Asian freshwaters, we report on an extensive study of the diversity of Collothecidae rotifers from fifteen freshwater habitats in Thailand. A total of 13 species, including two additional infraspecific variants, of Collothecidae are recorded, one of which is described as a new species of Collotheca. We further add taxonomic remarks on some of the taxa on record and illustrate the uncinate trophi of several representatives by scanning electron microscopic images. Finally, we provide illustrated identification keys to the Collothecidae recorded to date from Southeast Asia.

Mentions: We explored 15 freshwater habitats in 12 provinces of Thailand for Collothecidae during the present study (Fig. 1). Submerged parts of different species of aquatic plant were collected qualitatively to search for sessile rotifers. Collecting and observation methods are detailed in Meksuwan et al. (2011). Searching and identifying rotifers was performed under an Olympus SZ 51 stereo microscope and an Olympus CX 21 compound microscope. Drawings are based on photographs and observations of living animals. Trophi were prepared for scanning electron microscopy (SEM) following the method of Segers (1993), SEM photographs were taken using a FEI Quanta 400 SEM at the Scientific Equipment Center, Prince of Songkla University, Hatyai campus.
