Hypsibius convergens (Urbanowicz 1925) 

A total of 248 specimens were found in MR, LR, MT, LT and LF. Round, small septulum (following Guidetti & Bertolani (2001); since in Ramazzotti & Maucci (1983), they have doubts if there is a microplacoid or a septulum; however, in small specimens it was difficult to determine if it was a microplacoid or a septulum) was observed in specimens belonging to 20 % of the samples where the species appeared. Some specimens had cuticle bars between the double-claws of the fourth pair of legs as in Bertolani (1982). Mean body size was 524 μm (SD 127), range 209 to 1111 μm. The species is considered cosmopolitan ( McInnes 1994). In the Iberian Peninsula, in has been recorded for Spain ( Rodríguez Roda 1952; Mihelčič 1954; Maucci & Durante Pasa 1984; Maucci 1991) and Portugal ( Da Cunha 1941; Fontoura 1982; Maucci & Durante Pasa 1985). Hypsibius convergens  was collected from 40 of our sampling points (Table 3).
