Fig. 53 in Phylogeny Of Phyllostomid Bats (Mammalia: Chiroptera): Data From Diverse Morphological Systems, Sex Chromosomes, And Restriction Sites
Fig. 53. Evolution of the number of genal vibrissae inferred from optimization of character 12 on the strict consensus tree from our character congruence analysis. The equivocal reconstruction for the base of Mormoopidae is due to differences in interpretation under ACCTRAN and DELTRAN. The equivocal reconstructions for both Choeroniscus and Carollia are due to the presence of taxonomic polymorphism, and, in the case of Choeroniscus, different resolutions of the clade including this genus Choeronycteris, and Musonycteris. The ''uncertain'' state, which appears for several taxa (e.g., Lonchophylla, Lonchorhina), is due to taxonomic polymorphism (see character 12). To prevent an equivocal reconstruction for the base of Hirsutaglossa, we examined trees in which the position of Brachyphylla was resolved and fixed the node at the base of Hirsutaglossa with the state that occurred under the two alternative placements for this genus.
Fig. 52 in Phylogeny Of Phyllostomid Bats (Mammalia: Chiroptera): Data From Diverse Morphological Systems, Sex Chromosomes, And Restriction Sites
Fig. 52. Evolution of superciliary vibrissae inferred from optimization of character 11 on the strict consensus tree from our character congruence analysis. The equivocal reconstruction for the clade including Tonatia, Chrotopterus, and Vampyrum is due to the presence of taxonomic polymorphism in Tonatia and has two possible resolutions. The state for Lonchorhina and Tonatia is ''uncertain'' because of taxonomic polymorphism in these genera (see character 11).
Fig. 55 in Phylogeny Of Phyllostomid Bats (Mammalia: Chiroptera): Data From Diverse Morphological Systems, Sex Chromosomes, And Restriction Sites
Fig. 55. Evolution of the lateral vibrissal column inferred from optimization of character 14 on the strict consensus tree from our character congruence analysis. The equivocal reconstruction that begins with the last common ancestor of Phyllostominae and Nullicauda is due to differences in interpretation of the character under ACCTRAN or DELTRAN. The three taxa with asterisks after their names have only three vibrissae in each medial vibrissal column (character 15).

Fig. 51 in Phylogeny Of Phyllostomid Bats (Mammalia: Chiroptera): Data From Diverse Morphological Systems, Sex Chromosomes, And Restriction Sites
Fig. 51. Degree of internal uterine fusion (character 132) optimized onto the strict consensus tree from our character congruence analysis. There is a reversal to distinct cornual lumina from reduced cornual lumina (character 132) in some phyllostomines, suggesting that internal uterine fusion is not unidirectional. The equivocal optimization within Phyllostominae is due to missing data in Lonchorhinini. To prevent an equivocal reconstruction for the base of the clade that includes all phyllostomids except desmodontines, we examined trees in which the position of Brachyphylla was resolved and fixed the node at the base of the clade that includes all phyllostomids except desmodontines with the state that occurred under the two alternative placements for this genus.
