Morphology and Anatomy:

The genus Calcaridorylaimus was erected by Andr�ssy (1986) to accommodate a few species having different shapes and structures of spicules from those of Mesodorylaimus, with the males and females being practically indistinguishable . The most distinguishing features of the species are the shapes and structures of the spicules which have a small spur before the distal tip. (Nedelchev et al. 2014).

Distribution:

The genus has been reported mainly from the southern hemisphere; four species occur in Africa, two in South America and one each in Antarctic, Central America, and Europe; Calcaridorylaimus promissus was recorded from Australia and Alaska, North America Nedelchev et al., 2014; Swart et al., 2020).
