Abrochtha intermedia de Beauchamp 1909
Abrochtha intermedia: dorsoventral view. A species with two orange cerebral eyespots which are faintly visible in this image. The trochal pedicels are reduced in this species. This specimen was feeding on unicellular green algae (Oocystis sp.). Because of the red color of the intestine and the long tapered spurs this specimen was first misidentified as Philodina roseola, which occured in the same sample.
Abrochtha intermedia: dorsoventral view, rotatory apparatus retracted.
Abrochtha intermedia: ventral view, focus plane on the ventral part of the rotatory apparatus. Tr: trochus; Ci, cingulum; M: cavity leading to the mouth.
Abrochtha intermedia, lateral view.
Abrochtha intermedia: crop of the above image showing some details of the mastax. The arrow points to the ramus apophysis. The small triangles point to the 3 major teeth of the right uncus. Also visible is one of the two conspicuous cerebral eyespots. DA: dorsal antenna; Ro: rostrum.
Abrochtha intermedia: head with rostrum.
Abrochtha intermedia: three aspects of the head while creeping. Upper left: cilia of the rostrum. Upper right: rostrum lamella. Lower left: focus plane on the center of the rostrum. Possibly this image shows some sensory cells in the rostrum.
Abrochtha intermedia: trophi in cephalic view. Dental formula 3+1/ 1+2+1.
Location: Hagen, Germany, garden, sandstone bird bath.
Habitat: detritus (2). This species seems to occur preferably in ephemeral pools. (Together with Philodina roseola, Otostephanos torquatus amoenus). In contrast to the observation of other researchers this sample did not contain filamentous alge but coccal green algae (Oocystis sp.), desmids and procaryota (Croococcus sp.)
