RhinolophoideaNancy B. Simmons and Tenley Conway
This tree diagram shows the relationships between several groups of organisms.
The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.close box
All rhinolophoids are insectivorous or carnivorous, and all are restricted to the Old World. The largest family in the group is Rhinolophidae, which comprises 10 genera and over 130 species (Koopman, 1993). In addition to Rhinolophidae, two other families are included in the superfamily Rhinolophoidea: Nycteridae and Megadermatidae (Simmons, 1998; Simmons and Geisler, 1998). Nycteridae is a small family that includes only 1 genus and fewer than 20 species (Koopman, 1993), while Megadermatidae currently includes 4 extant genera and 5 species (Koopman, 1993). Macroderma gigas, a member of the family Megadermatidae, is the largest microchiropteran bat, with a wing span of 0.6m (Fenton, 1992).
- nasal branches of premaxillae reduced or absent.
- tympanic annulus semivertical in orientation.
- first rib at least twice the width of other ribs.
- first costal cartilage ossified and fused to manubrium.
- m. subclavius originates from first costal cartilage.
- m. omocervicalis originates from transverse process of C2.
- shaft of femur with bend that directs distal shaft dorsally.
- baculum saddle-shaped or slipper-shaped.
Many authors recognize Rhinolophidae and Hipposideridae as separate families, but there is overwhelming evidence that these groups are sister taxa (e.g., Pierson, 1986; Simmons, 1998; Simmons and Geisler, 1998; Kirsch et al., in press). Simmons (1998) and Simmons and Geisler (1998) followed Koopman (1993, 1994) in recognizing Hipposiderinae as a subfamily of Rhinolophidae, a nomenclatural arrangement that provides recognition of both the similarities and differences between these clades.
Within Rhinolophoidea, Simmons (1998) and Simmons and Geisler (1998) found strong support for a sister-group relationship between Rhinolophidae and Megadermatidae. This stands in contrast to some previous studies that suggested that Nycteridae and Megadermatidae might be sister-taxa (e.g., Smith, 1976). Monophyly of Nycteridae and Megadermatidae is strongly supported by morphological data (Griffiths, 1994; Simmons, 1998).
