2. Austrophilopterus flavirostris Carriker 1950 ( Figs. 6–7 )

Austrophilopterus cancellosus flavirostris Carriker 1950: 171 . Type host: " Pteroglossus flavirostris

mariae (Gould)" = P. azara mariae Gould.

Material. PERU: Holotype male, allotype female, La Pampa (MAC­3940; 1931); 1 male, 2 females, Loreto, 86 km SE Juanjui on E bank upper Rio Pauya, 0 7 33'40"S, 75 54'58"W (MS­3666: 2000).

Remarks. The description of this as a subspecies was based only on a male/female pair. Carriker stated that it, along with several other subspecies, is “...close to cancellosus .” He proceeded to cite a number of supposedly differentiating features associated with certain dimensions, shapes, and colorations. We do not feel any of these are of value in its recognition. To his credit, Carriker did mention the medial separation of the male abdominal tergal plates on VII, a feature we have found of value in separating most A. flavirostris from A. cancellosus .

Austrophilopterus cancellosus castanotus Carriker 1950: 173 . Type host: Pteroglossus castanotis

castanotis Gould. New Synonymy.

Material. PERU: Holotype male, allotype female, 1 male paratype, Sapasoa, Dept. Chachapoyas (MAC­8146; 1933).

Remarks. Carriker claimed this to be “Closest to A. flavirostris ”, but smaller, with dorsal head spiniforms much smaller and dorsoanterior head plate of different shape. These features fail to hold true after examination of a series of individuals. He did agree that a series of Austrophilopterus collected from P. c. australis Cassin were the same as those from P. c. castanotis .

Austrophilopterus cancellosus torquatus Carriker 1950: 174 . Type host: Pteroglossus torquatus

torquatus (J. F. Gmelin) . New Synonymy.

Material. COSTA RICA: Holotype male, allotype female, 3 male, 2 female paratypes, Guapiles (MAC­516; 1903). MEXICO: 2 males, 2 females, Campeche, 24 km S Silvituc, 18 14’N, 90 12’W (DHC PI­1; 1998). PANAMA: 1 male, 1 female, Barro Colo (JVT­ 270; 1927); 1 male, 1 female, Lion Hill (1911).

Remarks. Carriker provided only dimensional differences and nebulous morphological features as a means of recognizing this subspecies. All of these prove meaningless when considering features other than those associated solely with the holotype and allotype.

Female. Abdomen much as in Fig. 5 . Tergal setae: II, 2; III, 4–5 (25: 4.0); IV, 4–5 (25: 4.1); V, 4–6 (26: 4.3); VI, 4–6 (26: 4.6); VII, 4–8 (26: 5.8); VIII, 2–6 (26: 4.2).

Diagnosis. This species is separated from A. cancellosus by 29 of 30 males of the former having a distinct median separation between the tergal plates on VII and males with penis length only 0.070–0.090 (mean = 0.0822). The females are virtually inseparable, with a suggestion of difference in that the mean number of sternal setae for all segments of A. flavirostris is larger than for A. cancellosus . As stated earlier, these separations are not profound, but the recognition of these 2 as separate species is further supported by A. flavirostris being limited to hosts in the genus Pteroglossus and A. cancellosus limited to hosts in the genus Ramphastos .
