Basileuterus tristriatus chitrensis Griscom

Basileuterus tristriatus chitrensis Griscom, 1927a: 13 (Chitrá (4000 ft), Veraguas, Pacific slope of western Panama).

Now Basileuterus tristriatus melanotis Lawrence, 1868 . See Hellmayr, 1935: 491–492; Zimmer, 1949: 38; Blake, 1958: 561–562; Lowery and Monroe, 1968: 72; Wetmore et al., 1984: 314– 315; Dickinson, 2003: 767; Curson, 2010b: 795; and Lovette et al., 2010: 765–766.

HOLOTYPE: AMNH 257138 , adult male, collected at Chitra , 4000 ft, ca. 08.32N, 80.55W ( Siegel and Olson, 2008), Veraguas, western Panama, on 29 January 1926, by Rex R. Benson (no. 2055).

COMMENTS: Griscom cited the AMNH number of the holotype in the original description and listed two males from Santa Fé and seven males (in addition to the type), seven females and three sex? from Chitra. Paratypes in AMNH are: Santa Fe´ : AMNH 187748 , 187749 , males, 7 and 8 April 1925, by Benson ; Chitra , AMNH 246437–246453 , seven males, seven females, three sex?, December-March 1926, by Benson. I did not find AMNH 246438 in the collection .

Hellmayr (1935: 491–492) and Zimmer (1949: 38) recognized both melanotis and chitrensis; Lowery and Monroe (1968: 72) omitted melanotis, not listing Costa Rica within the range of tristriatus ; Dickinson, 2003: 767) apparently followed Lowery and Monroe and omitted melanotis. Blake (1958: 560–561) questioned the distinctness of melanotis and chitrensis ‘‘in view of the variability apparent in a representative series of melanotis from Chiriquí’’; Wetmore et al. (1984: 314–315) considered chitrensis a synonym of melanotis and correctly used the older name, melanotis Lawrence, 1868; Curson (2010b: 795) said ‘‘ melanotis (described from Costa Rica) is treated as [a] synonyn of chitrensis,’’ but, of course, if the two forms are synonyms, melanotis is senior by nearly 60 years.
