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).
