Vangullfer tnirandus, new species
(Figs. 26D-F, 27B, D)
"two new thin-billed drepanidine species" (part), James et al., 1987:2353.
Holotype: Maxilla lacking the left lateral nasal bar, USNM 445807 (Fig. 26DF).
Collected 23 March 1988 by H. F. James.
Type locality: Puu Naio Cave (305 m), Maui, Hawaiian Islands.
Distribution: Maui: Puu Naio Cave and Lua Lepo.
Etymology: Latin, mirandus, wonderful, strange.
Measurements (ram) o. fholotype: Dorsal length, 18.4; ventral length, 12.4; length
from lateral corner ofnasofrontal hinge, 18.9; length from jugal articulation, 15.7;
length from anterior margin of narial opening, 11.5; maximum width, approximately
7.4; length of narial opening, 5.4; height of narial opening, 3.1; height
through lateral nasal bar, 5.8; minimum width of dorsal nasal bar, 1.0.
Paratypes: Maxilla lacking the nasal bars, USNM 445806; slightly damaged
mandible consisting of the symphysis and the right ramus, USNM 445808 (Fig.
27B, D).
Measurements (ram) o. fparatypes: Maxilla: ventral length, 11.2; length from
jugal articulation, 16.0; length from anterior margin ofnarial opening, 11.1; maximum
width, 7.2. Mandible: total length, 28.2; length oftomial crest, 14.6; symphysis
length, 9.8; greatest width ofsymphysis, 6.3 +; symphysis height, 2.4; length
of lateral cotyla, 2.8; length of lateral cotyla plus retroarticular process, 3.0; height
at lateral cotyla, 1.4; height at angle of mandible, 2.6; length of ramus (middle
part), 12.1.
Diagnosis: Compared to Vangul•fer neophasis, the maxilla is more decurved
and not nearly as deep, the narial opening is much smaller, the entire ventral
surface of the maxilla is much less excavated and is more distinctly pitted anteromedially,
the splaying of the medial groove is more pronounced, and the tomial
crest is flared laterally toward the jugal articulations, as opposed to being straight.
While the mandible is similar in overall size to that of V. neophasis, the articular
end is smaller and the retroarticular process is much shorter.
Remarks: In several characters, V. mirandus is more similar to aerial insectivores
than is V. neophasis. The maxilla is not as deep, its ventral surface is nearly
flat rather than domed, and the articular end of the mandible is reduced in size.
However, a curved bill would not be expected in a bird that fed exclusively by
catching insects on the wing. |
