Two eggs of White-headed Marsh Tyrant Arundinicola leucocephala from the Schönwetter collection at Halle (Saale) University, showing the match to Burmeister's description of the morphology of the eggs of 'his' Dixiphia leucocephala in 1853. Burmeister's original egg of the species is no longer present among his collection at Halle (Frank Steinheimer / © ZNS, Halle/Saale).

FIGURE 21 in A new genus and new species of fan worms (Polychaeta: Sabellidae) from Atlantic and Pacific Oceans—the formal treatment of taxon names as explanatory hypotheses

FIGURE 21. Detail of the phylogenetic hypothesis, Sabellomma, and specific hypotheses, from Fig. 20, showing optimizations of dorsal pinnular appendages. The formal definitions of these hypotheses are also presented, indicating that specific hypothesis S. minuta cannot be defined (cf. Figs 23–24 for alternative optimizations).

FIGURE 23. Detail of the phylogenetic and specific hypotheses from Fig. 22, showing optimizations of dorsal pinnular appendages. The formal definitions of these hypotheses are also presented, indicating that specific hypotheses S. collinae and S. harrisae cannot be defined (cf. Figs 21, 24 for alternative optimizations).

FIGURE 20 in A new genus and new species of fan worms (Polychaeta: Sabellidae) from Atlantic and Pacific Oceans—the formal treatment of taxon names as explanatory hypotheses

FIGURE 20. Strict consensus tree presented in Fig. 19, but 'inapplicable' character optimizations for distribution of simple eyes (subject 9; cf. Tables 6–7) correctly treated as inapplicable. Note that Sabellomma is monophyletic on the basis of simple eyes distributed along the entire lengths of radioles [9(1)]. Relationships among Sabellomma are determined by one of the optimizations of dorsal pinnular appendages (subject 13); compare with alternate optimization in Fig. 22.

FIGURE 19 in A new genus and new species of fan worms (Polychaeta: Sabellidae) from Atlantic and Pacific Oceans—the formal treatment of taxon names as explanatory hypotheses

FIGURE 19. Strict consensus tree of six minimum-length cladograms (phylogenetic analysis 2 - see text for discussion), showing relationships among apomorphic genera within Sabellinae. Note that the genus Sabellomma is paraphyletic. Character optimizations across all cladograms are indicated for the following subjects (cf. Tables 6–7): 9. distribution of simple eyes along radiole margins; 13. dorsal pinnular appendages; 21. interramal eyespots. Note the ambiguous optimizations for distribution of simple eyes, as a consequence of the use of 'inapplicable' codings.
