Gnatcatchers (Polioptilidae)
White-lored Gnatcatcher (Polioptila albiloris) - HBW 11, p. 372
French: Gobemoucheron à face blanche
German: Weißzügel-Mückenfänger
Spanish: Perlita Cejiblanca
Taxonomy: Polioptila albiloris P. L. Sclater and Salvin, 1860, Motagua Valley, Zacapa, Guatemala.
Has in the past been treated as conspecific with P. nigriceps. Birds of nominate race in arid thorn-scrub of Motagua Valley, in C Guatemala, appear to be ecologically isolated from putative conspecifics; study needed of distribution in region between 89°-90° W and 15°-14° N. Distribution in Honduras from vicinity of Cantarranas N towards Aguan Valley similarly uncertain; has been suggested that this population is disjunct. Three subspecies recognized.
Subspecies and Distribution:
- vanrossemi Brodkorb, 1944 - S Mexico (N Guerrero and N Oaxaca S to C & S Chiapas).
- albiventris Lawrence, 1885 - coast of NW & CN Yucatán, in E Mexico.
- albiloris P. L. Sclater & Salvin, 1860 - arid valleys of C Guatemala, interior Honduras and El Salvador S in Pacific lowlands to NW Costa Rica.
