Diphascon (Adropion) scoticum Murray 1902

I collected 78 specimens from LF samples. No drop present between the buccal and pharyngeal tubes. Three rod-shaped macroplacoids, microplacoid and septulum (as specimens studied by Ramazzotti and Maucci (1983)) within the pharyngeal bulb, but I observed one specimen lacking the septulum in the pharyngeal bulb as Pilato (1974) and Ito (1995) did for this species. Cuticle bars, when present, appeared in the inner zone of the internal double-claws and/or between external and internal double-claw of the first three pairs of legs. Mean body size was 754 μm (SD 254), range 418 to 1496 μm. This species is considered cosmopolitan. In the Iberian Peninsula, it has been recorded for Spain ( Rodríguez Roda 1946, 1952; Maucci & Durante Pasa 1984). It is the first record for Madrid ( Table 2 ). Diphascon (Adropion) scoticum was collected in 17 sampling points (Table 3).
