Price, Roger D. & Weckstein, Jason D., 2005, The genus Austrophilopterus Ewing (Phthiraptera: Philopteridae) from toucans, toucanets, and araçaris (Piciformes: Ramphastidae), Zootaxa 918, pp. 1-18: 13-14

5. Austrophilopterus andigenae Carriker 1950  Edit

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

Andigena hypoglauca lateralis Chapman.  Edit

Material. PERU: Holotype female, allotype male, 3 male, 9 female paratypes, Huacapistana (MAC­ 1494; 1930); 3 males, 4 females, Leymebamba (MAC­ 5464; 1932).

Remarks. Carriker compared this species with A. cancellosus  Edit 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  Edit lice from Aulacorhynchus  Edit , which we have found to be extremely close morphologically.

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

Chapman. New Synonymy.

Material. COLOMBIA: Holotype female, allotype male, 1 male, 2 female paratypes, Bitaco (MAC­ 25345; 1918); 2 females, Cauca, Cerro Munchique (MAC­ 24171; 1965).

Remarks. Carriker admitted that this species is similar to A. andigenae  Edit 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  Edit . Type host: Pteroglossus sanguineus  Edit .

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

Material. COLOMBIA: Holotype male, allotype female, female paratype, Dept. Chocó, Rio San Juan, Potedó (MAC­ 24198; 1918).

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

Diagnosis. The principal feature for separation of A. andigenae  Edit from A. truncatus  Edit 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  Edit have dimensions larger than those of A. truncatus  Edit 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.
