A new record from East Malaysia: Sphaerolaimus macrocirculus (Nematoda)

A new record of Sphaerolaimus macrocirculus (Filipjev 1918) in East Malaysian coastal water was described. The species was isolated from the muddy area of Muara Tebas, Sarawak, Malaysia. A total of 47 species of Sphaerolaimus have been reported worldwide. Samples of Sphaerolaimus macrocirculus were...

Samples of Sphaerolaimus macrocirculus were previously recorded in the sublittoral mud area of temperate country. S. macrocirculus possesses a stout body (1.1 - 1.6mm; De Man ratios: a (body length/body width) = 16.8–27.5; b (body length/oesophagus length) = 2.3–4.3;c (body length/tail length) = 5.6–8.6). The circular amphid is very clear and situated at the base of the cephalic capsule. In male, the amphid ranged from 11.3-14.3 μm in diameter (mean = 12.7 ± 1.3) and 0.4 c .d.(corresponding diameter). In female, the amphid ranged from 7.2–9.4 μm in diameter (mean 7.8 ± 0.9) and 0.2 c.d. The species is characterised by the presence of eight groups of subcephalic setae at the head region and three longer terminal setae.
