11. *The classification should use currently recognized monophyletic groups whenever possible. 12. They are monophyletic , and possibly closest related to the Linyphiidae. 13. Indeed, molecular phylogenies suggest that all extant Feliformia are monophyletic . 14. Combined morphological and molecular analyses have shown Dromopoda to be monophyletic . 15. Unlike some related currently recognized families, the Nemastomatidae are monophyletic . 16. However, the monophyletic nature of these three groups remains unknown. 17. The Erebidae are one monophyletic family among six in the Noctuoidea. 18. Since that time, most studies have supported a monophyletic Sebecosuchia. 19. Research into the monophyletic and appears to have multiple evolutionary origins. 20. The subfamilies Acheilognathinae, Gobioninae, and Leuciscinae are monophyletic .
