Kirkegaardia dorsobranchialis (Kirkegaard, 1959)

Monticellina dorsobranchialis (Kirkegaard, 1959) | Tharyx dorsobranchialis (Kirkegaard, 1959)

Notes

A species reported from worldwide locations, partly caused by inaccurate descriptions in the past; therefore Blake (2016) considers the presence of Kirkegaardia dorsobranchialis in the Mediterranean uncertain and possibly restricted to West and South Africa. Many Greek records of Kirkegaardia dorsobranchialis belong in fact to Kirkegaardia heterochaeta (Laubier, 1961), as Blake (1991) had synonymised Monticellina heterochaeta with Monticellina dorsobranchialis . The distinction between the two species is difficult. Kirkegaardia heterochaeta has a longer peristomium than Kirkegaardia dorsobranchialis and posesses a mid-dorsal ridge within the dorsal channel which is absent in Kirkegaardia dorsobranchialis . The most reliable factor for their separation is the methyl green staining pattern ( Blake 2016).
