Bioacoustics of Orientafroinsularis pulverulenta

Remarks.—As outlined above, the subspecies Antankaria pulverulenta madagassa and Chremistica pulverulenta madagascariensis are considered to be the nominotypical taxon Orientafroinsularis pulverulenta n. comb. since Boulard (2001) specifically redescribed Distant’s species and the portion of the song illustrated in Boulard (1999) is similar to that illustrated at the end of the call in Boulard (2001) . The synonymy or elevation to species rank of all subspecies means the trinomial designation is no longer necessary. The smallest species of the genus with a body length of 20–22 mm and a wingspan of 55–58 mm ( Distant 1905b ; Boulard 2001 ; specimens in hand). A tawny species marked with testaceous and a small amount of piceous. The initial song with begins as a series of short syllables followed by a period of rapidly produced syllables of increasing intensity followed by a period of various amplitude modulation becoming separated into individual syllables with peak energy about 11 kHz ( Boulard 2001 ). Distribution.—The species has been reported from Madagascar and several islands in the Seychelles ( Metcalf 1963a ; Sanborn 2103) but the references to the Seychelles are considered to be references to Orientafroinsularis seychellensis ( Boulard, 1999 ) n. comb. , rev. stat. Jacobi (1917) reported the species from Tulear, southwestern Madagascar and Kinkoni-See, northwestern, Madagascar . Boulard (2001) reports the species from Morondavar to Mahabo, Diego Suarez, Joffreville, Manambina, Miandrivazo, the forest of Kirindy, Antsohihy, and around Lake Konanamby.
