Austrophilopterus andigenae

Type
host: "
Andigena hypoglaucus

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.

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.

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
.

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.
