Righiodrilus

James, Samuel W. & Gamiette, Franciane, 2016, New species of Dichogaster Beddard, 1888 (Clitellata: Benhamiidae) with additional records of earthworms from Guadeloupe (French West Indies), Zootaxa 4178 (3), pp. 391-408 : 402

Righiodrilus sp.

( Figure 5 )

Material examined. 2 juveniles, Madelaine, N16°00.825', W61°38.902', 685 m asl, pumice-based soils of humid montane forest.

Juvenile specimens with Glossodrilus -like morphology, with the exception of having bilobed reservoirs on top of the calciferous glands in xii, main lobe half-ovate in xii, smaller internally bifurcate lobe attached to main lobe by short stalk passing through 12/13 to xiii ( Fig. 5 ).

Remarks. Righiodrilus Zicsi, 1995 is defined by having a reservoir on the dorsal surface of the calciferous glands; otherwise it is the same basic morphology as Glossodrilus ( Zicsi 1995) . These small endogeic worms were abundant in the locality and in life the brilliant white of the calcium carbonate particles in the reservoir is very easily seen, including the small posterior lobe of the reservoir. This species could be an introduction but until adults are obtained the identification remains uncertain.
