A Review of the Genera Croconema Cobb, 1920 and Pseudochromadora Daday, 1899 (Nematoda, Desmodoroidea): New Species from the Coasts of Kenya and Australia

Abstract

This article is a review of the subfamily Desmodorinae (Nematoda, Desmodoroidea) and two related genera within this subfamily, Croconema

Four new species ofDesmodora(Nematoda) from the deep south-east Atlantic, and a case of intersexuality in Desmodoridae

“…The presence of longitudinal alae in Desmodorinae has been reported for Psammonema Verschelde & Vincx, 1995, Pseudochromadora Daday, 1889 and Sibayinema Swart & Heyns, 1991, according to Verschelde et al (2006). For the genus Desmodora , D. vietnamica Gagarin & Vu Thahn Nguyen, 2010, also shows two lateral alae.…”

“…For the family Desmodoridae, conspicuous pores restricted to the head capsule were recorded in Pseudochromadora Daday, 1889, Psammonema Verschelde & Vincx, 1995 and in Desmodorella by Cobb (1933). Specifically, such pores can be seen in Desmodorella balteata Verschelde et al, 1998; Pseudochromadora galeata Verschelde et al, 2006; Pseudochromadora securis Verschelde et al, 2006; Pseudochromadora buccobulbosa Verschelde & Vincx, 1995; and Psammonema ovisetosum Verschelde & Vincx, 1995. Pores in the head capsule also occur in other orders of nematodes, such as in Ceramonematidae: Ceramonema Cobb, 1920 and Pselionema Cobb, 1933, members of the order Plectida Malakhov, 1982.…”

The use of nematodes in assessing ecological conditions in shallow waters surrounding a Mediterranean harbour facility

“…One-hundred nematodes from each replicate were randomly picked out using fine pin under a stereomicroscope (magnification Â40), transferred from formalin to glycerol through a series of ethanoleglycerol solutions, and mounted on slides in anhydrous glycerine, following the procedure described by Heip et al (1985). Nematodes were identified at genus level using the pictorial keys of Warwick (1983, 1988) and Warwick et al (1998), as well as the NeMys online identification key (Steyaert et al, 2005) and additional taxonomic papers (e.g., Verschelde et al, 2006).…”

7.13 Order Desmodorida De Coninck, 1965
