Broadbills (Eurylaimidae)

Silver-breasted Broadbill (Serilophus lunatus) - HBW 8, p. 89

French: Eurylaime de Gould German: Schwarzbrauen-Breitrachen Spanish: Eurilaimo Pechoplata
Other common names: Collared/Gould’s Broadbill; Hodgson’s Broadbill, Red-backed Broadbill, Nepal Collared Broadbill (rubropygius); Pegu Collared Broadbill (lunatus)

Taxonomy: Eurylaimus lunatus Gould, 1834, hills of Pegu District, Myanmar.
Race rubropygius was formerly considered a separate species, as thought to be sympatric with nominate in two areas, but recent examination of critical specimens indicates that ranges do not overlap, although closely approaching each other in NE Myanmar; one old record from Chin Hills, in NW Myanmar, attributed to nominate, remains unresolved. Status of some isolated populations, particularly in SE Thailand and Indochina, and the boundaries between and validity of several races, are poorly understood and require further study; atrestus and aphobus often synonymized with ..

Taxonomy: Eurylaimus lunatus Gould, 1834, hills of Pegu District, Myanmar.
Race rubropygius was formerly considered a separate species, as thought to be sympatric with nominate in two areas, but recent examination of critical specimens indicates that ranges do not overlap, although closely approaching each other in NE Myanmar; one old record from Chin Hills, in NW Myanmar, attributed to nominate, remains unresolved. Status of some isolated populations, particularly in SE Thailand and Indochina, and the boundaries between and validity of several races, are poorly understood and require further study; atrestus and aphobus often synonymized with elisabethae, while birds occurring in lowland S Laos are considered probably to belong to atrestus, rather than to impavidus, which is better treated as confined to Bolaven Plateau. Described races intrepidus (NE Thailand) and moderatus (N Sumatra) considered unacceptable. Ten subspecies recognized.

Subspecies and Distribution:

  • rubropygius (Hodgson, 1839) - NE India, Bhutan and E Bangladesh E to W & NE Myanmar (Arakan, Chin Hills and Upper Chindwin E to R Irrawaddy).
  • atrestus Deignan, 1948 - C & E Myanmar (S of Bhamo, E of R Irrawaddy) and S China (SW Yunnan) S to NE Thailand, C & S (lowland) Laos and NW Vietnam (W Tonkin).
  • elisabethae La Touche, 1921 - SE China (SE Yunnan, SW Guangxi) and E Tonkin.
