Anillinus magnus Zaballos and Mateu 1997: 137 .

The illustrations of the single female type of the species do not offer much for comparison because the spemathecae of many species of Anillinus have not been studied thoroughly. But, two groups of eastern U.S. Anillinus are well-known in that respect ( Sokolov et al. 2007; Sokolov and Carlton 2010), allowing insight as to the affinities of A. magnus . The most distinctive features of the spermatheca of A. magnus are the sharp differentiation of the distal and proximal parts of cornu and a bulb-like enlargement of the ramus. This type of spermatheca does not match Anillinus spermathecae that have been described. The latter are characterized by the gradual transition between the distal and proximal parts of the cornu and the reduced and undifferentiated ramus zone. However, the spermathecal morphology of Serranillus species (Sokolov and Carlton 2008) is quite consistent with that of A. magnus , based on the description and illustration. Serranillus spermathecae possess sclerotized distal parts of the cornu having a beanlike shape, while the proximal part of the cornu is unsclerotized and straight. The ramus is well differentiated, sclerotized, and ovoid. Comparison of the figures of the spermatheca of A. magnus with those of Serranillus suggests a near perfect match ( Fig. 2 ). Accordingly, we conclude that A. magnus does not belong in Anillinus , but rather in Serranillus .

NOMENCLATURAL CHANGES

Based on the evidence presented above, we propose the following taxonomic changes:

Anillinus steevesi Barr, 1995 = Anillinus minor Zaballos and Mateu, 1997 , new synonym.

Serranillus magnus (Zaballos and Mateu, 1997) , new combination = Anillinus magnus Zaballos and Mateu, 1997 .
