The spermatozoa of #Homologenus$ sp., #Latreillopsis$$ sp., #Homolomannia sibogae$ and #Paramolopsis boasi$ confirm characteristics of a distinctive homolid spermatozoon previously established for #Homola$ sp., #Paromola petterdi$. Homolid features are (1) moderate anteroposterior depression of the acrosome(ratio of length : width 0.4-0.6) as in lyreidine raninids (O.5), depression being greater in dromiids and dynomenids (both 0.3); (2) the capitate form of the perforatorium, shared with dromiids, dynomenids and lyreidine raninids; (3) the autapomorphic spiked-wheel form of the anterior expansion of the perforatorium; (4) horizontal zonation of the acrosome is possibly a unique synapomorphy of homolids with dromiids and dynomenids, and therefore an autapomorphy of the dromioid-homolid assemblage. In dromiids the posterior zone is proportionately the larger, while in homolids the anterior zone is the larger. (D'après résumé d'auteur)
