Tychaedon is a genus of passerine birds in the Old World flycatcher family Muscicapidae that are found in Sub-Saharan Africa. It contains species that were formerly placed in the genus Cercotrichas.

Taxonomy

The species now placed in this genus were previously placed in the genus Cercotrichas. A molecular phylogenetic study of the family Muscicapidae published in 2023 found that Cercotrichas was paraphyletic.[1] In the rearrangement to create monophyletic genera, some species were moved to the resurrected genus Tychaedon.[2] This genus had been erected in 1917 by the American ornithologist Charles Wallace Richmond as a replacement name for Aedonopsis that had been introduced by Richard Bowdler Sharpe 1883. The type species is Cossypha signata Sundevall, 1850, the brown scrub robin.[3][4] The genus name Tychaedon combines Ancient Greek τυχη/tukhē meaning "chance" or "luck" with αηδων/aēdōn, αηδονος/aēdonos meaning "nightingale" or "songstress".[5]

These are African species of open woodland or scrub, that nest in bushes or on the ground.

The genus contains the following five species:[2]

Karoo scrub robin Tychaedon coryphoeus southern Africa
Brown scrub robin Tychaedon signata forests of eastern southern Africa
Forest scrub robin Tychaedon leucosticta sparsely present throughout the African tropical rainforest
