Fig. 4 in A new species of Lonchophylla (Chiroptera: Phyllostomidae) from the eastern Andes of northwestern South America

Fig. 4. Ventral view of P4 of Lonchophylla handleyi: (A) USNM 588021, (B) AMNH 230215; L. chocoana: (C) ROM 105798, (D) ICN 4395; L. robusta: (E) ICN 13648; L. orienticollina: (F) ICN 10114. Note the differences in size, degree of development, and bluntness across species and individuals. A and C each have a cusp, but it is blunt compared to that of E or F. B has a small cusp, while D has an indistinct protuberance in place of a cusp.

Fig. 5 in A new species of Lonchophylla (Chiroptera: Phyllostomidae) from the eastern Andes of northwestern South America

Fig. 5. Plot of regression factor scores on the first and second axes from principal component analyses of eight variables measured from 34 Lonchophylla robusta, and 23 L. orienticollina. Factor loadings for cranial dimensions on PC 1 are positive (table 2), so the largest individuals have the highest scores on that axis.

Fig. 3 in A new species of Lonchophylla (Chiroptera: Phyllostomidae) from the eastern Andes of northwestern South America

Fig. 3. Map of southern Central America and northwestern South America illustrating localities for specimens of sympatric Lonchophylla of similar size. L. handleyi is included because it has been found in sympatry with orienticollina at Yaupi, Morona Santiago, Ecuador.

Fig. 6 in A new species of Lonchophylla (Chiroptera: Phyllostomidae) from the eastern Andes of northwestern South America

Fig. 6. Environmental niche model (ENM) of Lonchophylla orienticollina based on 19 unique localities. All known localities were used to generate the model, and 10,000 random points from the background were used as pseudo-absences. The degree of suitability was based on the least restrictive, second most restrictive, etc., of the non-fixed thresholds provided by maxent.
