Certhia longirostra

Latham

Tippera district, Bangladesh

.

Until recently considered conspecific with A. dilutior and A. flammifera, which see. Additional proposed races, all considered insufficiently distinct, are vantynei (from Jagalbed, Bombay, in W India), subsumed into nominate, and antelia (Trang, in S Thailand), heliocrita (Selitar, near Singapore), melanchima (upper R Siak, in E Sumatra), hypochra (North Pagai I), and exochra (South Pagai I), all synonymized with cinereicollis. Race cinereicollis originally spelt “cinireicollis” but this is a misspelt Latin word, and must be corrected. Ten subspecies recognized.
