| Notes |
Diagnosis: Antedoninae with distal ends of cirrals not produced and overlapping. Third pinnule longest and stoutest. [details] Taxonomic Remark: "Mr. A. H. Clark included, without comment, the nominal genus Monilimetra H. L. Clark, 1938, in the synonymy of Toxometra. Since it also shares with Dorometra the character of the enlarged P3 some comparison is called for as justification for this move, particularly as it was with Dorometra that H. L. Clark gave a comparison. The cirrus segments of Toxometra paupera are distinguished from those of the species of Dorometra by the absence of flared and overlapping distal ends and the relatively shorter distal segments. Monilimetra bicolor appears to approach Dorometra in these characters, to judge from H. L. Clark's figures, but the other three species of Monilimetra have cirri approximating more to those of Toxometra. No mention was made by H. L. Clark of spinous distal productions of the brachials in any of the species of Monilimetra, which are therefore taken to have smooth brachials like those of Dorometra rather than flared spinous ones like Toxometra paupera. However, this character probably has no great reliability...In view of the variable proportions of P4 relative to P3 in T. paupera it is doubtful whether this character is of any use in distinguishing T. lepta. The occurrence of four sympatric species seems to me improbable and the morphological differences between them too slight for all to be justified."
