Least Concern

Frilled Monarch (Arses telescopthalmus)


French: Monarque à collerette German: Krausenmonarch Spanish: Monarca elegante

Muscicapa telescopthalmus

#R Lesson and Garnot

, 1827,

Manokwari, north-western New Guinea


Formerly regarded as conspecific with A. insularis (see above), and the two have hybridized. Recent molecular studies#R#R report that A. lorealis and A. kaupi are embedded in a broad clade with present species but more closely related to taxa from SE New Guinea than latter are to taxa from NW New Guinea, implying that, if lorealis and kaupi are retained as species, the W New Guinea taxa (nominate, batantae, aruensis) must likewise be given species rank; these taxa, however, are so difficult to distinguish from those in SE New Guinea#R, while lorealis and kaupi are so distinctive, that it seems important to pursue more detailed study in order to verify or modify the arrangement suggested by the molecular evidence. Proposed form henkei (SE New Guinea) recognized by some authors#R#R, but here and elsewhere#R regarded as intergrade between harterti and lauterbachi; name henkei, if recognized as valid, has priority over lauterbachi#R. Five subspecies recognized.

Subspecies and Distribution
  • A. t. batantae Sharpe, 1879 – West Papuan Is (Waigeo, Batanta), in NW New Guinea.

  • A. t. aruensis Sharpe, 1879 – Aru Is.
  • A. t. harterti van Oort, 1909 – S New Guinea from Mimika R E to Purari R, and Boigu I (in N Torres Strait).
