Introduction
Thermosbaenaceans are small (‹4 mm) benthic or interstitial crustaceans of fresh, anchialine and marine waters, including caves.
The order has been thought to be the only representative of a separate superorder, Pancarida (e.g. Bowman & Abele 1982) but modern interpretations tend to place the group within the Peracarida, ignoring the lack of oostegites and absence of lacinia mobilis (Dahl 1983; Watling 1983; Cals & Monod 1991). The number of species worldwide is currently about 34 species in seven genera according to the most thorough reviews of biology and systematics (Wagner 1994; Monod & Cals 1999) but there are conficting views on the family arrangement (Bowman & Iliffe 1988; Monod & Cals 1988). The order is most common in the Mediterranean and Caribbean areas with a species in Cambodia and another in Australia (Poore & Humphreys 1992).
Diagnosis
Carapace attached to first thoracomere which functions as a brood pouch in female; with 1 pair of thoracic maxillipeds; thoracopods 2–8 biramous, without epipods; pleopods reduced or absent; telson and uropods acting as tailfan.
