5. Austrophilopterus andigenae Carriker 1950

Austrophilopterus andigenae Carriker 1950: 175 . Type host: " Andigena hypoglaucus (Gould) " =

Andigena hypoglauca lateralis Chapman.

Material. PERU: Holotype female, allotype male, 3 male, 9 female paratypes, Huacapistana (MAC­1494; 1930); 3 males, 4 females, Leymebamba (MAC­5464; 1932).

Remarks. Carriker compared this species with A. cancellosus and its allies, discussing several good differentiating features. We agree with these, as these species are quite different. However, he did not make mention of any similarities with Austrophilopterus lice from Aulacorhynchus , which we have found to be extremely close morphologically.

Austrophilopterus pacificus Carriker 1950: 177 . Type host: Andigena nigrirostris occidentalis

Chapman. New Synonymy.

Material. COLOMBIA: Holotype female, allotype male, 1 male, 2 female paratypes, Bitaco (MAC­25345; 1918); 2 females, Cauca, Cerro Munchique (MAC­24171; 1965).

Remarks. Carriker admitted that this species is similar to A. andigenae in many respects. He cited the sclerites of the male genitalia as affording the most striking difference, but we do find this to be the case.

Austrophilopterus pacificus sanguineus Carriker 1950: 178 . Type host: Pteroglossus sanguineus .

Gould = most likely erroneous host. Probably some member of Andigena . New Synonymy.

Material. COLOMBIA: Holotype male, allotype female, female paratype, Dept. Chocó, Rio San Juan, Potedó (MAC­24198; 1918).

Remarks. Based only on the male/female type pair, the extremely close agreement in morphological features, including dimensions, with those of A. andigenae makes it extremely unlikely that P. sanguineus is the true type host. Carriker must have felt this could be true, as he stated that A. p. sanguineus agreed “...in every way with those taken on the genus Andigena , and is very close to A. pacificus ”, which he noted is also from western Colombia.

Genitalia close to Figs. 11–12 , with GL, 0.40–0.51 (6: 0.427), GPL, 0.035– 0.050 (11: 0.0441). Dimensions: TW, 0.51–0.59 (14: 0.551); HL, 0.54–0.63 (15: 0.597); PW, 0.34–0.38 (14: 0.355); MW, 0.43–0.49 (13: 0.458); AWV, 0.63–0.73 (14: 0.679); TL, 1.57–1.79 (13: 1.639).

Diagnosis. The principal feature for separation of A. andigenae from A. truncatus involves the former having tergite II with 4–6 (mean for N (39) = 4.44) marginal setae and the latter having only 2–4 (mean for N (94) = 2.87) such setae. In addition, both sexes of A. andigenae have dimensions larger than those of A. truncatus and also tend to have more setae on sternites II–VII. These are not profound separations but ones that are sufficient to make us reluctant to synonymize louse taxa from these 2 different host genera.
