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 : 10-13

4. Austrophilopterus truncatus ( Piaget 1888) ( Figs. 9–13 )

Docophorus truncatus Piaget 1888: 149 . Type host: " Aulacorhynchus rubrogularis " = mistranscrip­

tion for A. prasinus atrogularis (Sturm) (see Hopkins and Clay 1952: 50).

Material. PERU: Holotype male, allotype female, female paratype of A. s. subspinosus Carriker, Eneñas, Pichis Trail (MAC­1375; 1930); 1 female, Mann N.A. (TP­1228; 2001); 1 male, 1 female, San Martin, 24 km ENE Florida, 0 5 41’09”S, 77 45’16”W (AWK­2470; 2002).

Remarks. The description by Piaget with the illustration of the single entire female type specimen clearly shows the body details and pointed shape of the dorsoanterior head plate. This leaves little doubt that our material represents this species.

Austrophilopterus spinosus spinosus Carriker 1950: 181 . Type host: "Aulocorhynchus caeruleicinc­

tus borealis Carriker" = Aulacorhynchus coeruleicinctis d'Orbigny. New Synonymy.

Material. PERU: Holotype male, allotype female, 2 female paratypes, Huacapistana (MAC; 1930); 2 males, 7 females, Oconeque (MAC­3137; 1931); 1 female, Perene (MAC; 1929). BOLIVIA: 4 males, 5 females, Sandillani (MAC­10740; 1934); 1 male, 2 females, Santa Cruz, Chuchial, ca. 37 km SE Samaipata, 18 22.9’S, 63 37.2’W (JLK­155 and DFL­1198; 1999); 1 female, Santa Cruz, La Pajcha, ca. 28 km S Samaipata, 18 23.8’S, 63 49.7’W (DLD­6966).

Remarks. Little more is given other than dimensions and vague morphological features to differentiate this subspecies from the nominate form. These do not prove useful when compared to additional specimens.

Austrophilopterus spinosus subspinosus Carriker 1950: 182 . Type host: "Aulocorhynchus atrogu­

laris (Sturm)" = Aulacorhynchus prasinus atrogularis (Sturm) .

Material. PERU: Holotype male, allotype female, 1 female paratype, Eneñas, Pichis Trail (MAC­1375; 1930).

Remarks. Carriker apparently was unaware of the much earlier description of A. truncatus , thereby contributing to this falling to junior synonymy as established by Price et al. (2003). His mention of only trivial features for recognition of this subspecies does nothing to justify its separation.

Austrophilopterus spinosus microgaster Carriker 1950: 183 . Type host: "Aulocorhynchus derbianus

(Gould)" = Aulacorhynchus derbianus Gould. New Synonymy.

Material. PERU: Holotype male, allotype female, 5 males, 1 female, Eneñas (MAC­1361; 1930); 1 male, 1 female, La Oroya (MAC­3416; 1931); 1 female, Cajamarca, ca. 3 km NNE San José de Lourdes, 0 5 4.3’S, 78 52.9’W (DFL­1036; 1998). BOLIVIA: 1 male, 1 female, Dpto. de Cochabamba, Chapare, Villa Tunari, 43 km W San Onofre, 17 09'S, 65 47'W (VGR­234; 2002).

Remarks. Carriker indicated that this subspecies seems to lie between A. s. spinosus and A. s.

subspinosus, without giving any substance to support this separation.

Austrophilopterus spinosus calorhynchus Carriker 1950: 185 . Type host: "Aulocorhynchus calo­

rhynchus (Gould)" = Aulacorhynchus sulcatus calorhynchus (Gould) . New Synonymy.

Material. COLOMBIA: Holotype male, allotype female, 3 male, 2 female paratypes, Magdalena, Los Garros (MAC­5893; 1945); 2 females, Sta. Marta, Hcda. Cincinnati (MAC­12340; 1913).

Remarks. Carriker claimed this subspecies to be very close to A. s. microgaster . Only vague small differences along with the usual dimensions for the type specimen pair were given to support the recognition of this taxon; however, these fail to afford separation.

Austrophilopterus tenuicapitis Carriker 1950: 185 . Type host: "Aulocorhynchus haematopygius

(Gould)" = Aulacorhynchus haematopygus (Gould) . New Synonymy.

Material. COLOMBIA: Holotype male, allotype female, 2 male, 5 female paratypes, Sierra Perijá, Tres Tetas (MAC­2433; 1942); 2 males, Caldas, Rio Samaná, Hcda. Sofia (MAC­ 20189 and 20311; 1951).

Remarks. Carriker claimed this subspecies to be much smaller than A. spinosus , almost as small as A. minutus , and with a very narrow head. These differences do not prove to be valid when compared to specimens of the other taxa.

Austrophilopterus minutus minutus Carriker 1950: 186 . Type host: "Aulocorhynchus p. prasinus

(Gould)" = Aulacorhynchus prasinus prasinus (Gould) . New Synonymy.

Material. MEXICO: Holotype male, allotype female, 3 male, 6 female paratypes, Vol. San Martin (MAC­782; 1940). VENEZUELA: 5 males, 8 females, Merida, Tabay (4465: 1966).

Remarks. Carriker referred to this as the smallest known form of the genus, but dimensions of the series available show sufficient overlap with other taxa as to preclude separation. He also claimed that the male genitalia differ in detail from other Aulacorhynchus forms, but we do not find this to be the case.

Austrophilopterus minutus sulcatus Carriker 1950: 187 . Type host: "Aulocorhynchus s. sulcatus

(Swainson)" = Aulacorhynchus sulcatus sulcatus (Swainson) . New Synonymy.

Material. VENEZUELA: Holotype male, allotype female, 1 male, 3 female paratypes, San Esteban (MAC­8645; 1910); 4 male, 4 female, Los Minos (Correo; 1944); 1 male, Monagas, Caripe (13968; 1967).

Remarks. Stated by Carriker to be close to A. m. minutus , even smaller in some dimensions, but again his flawed application of dimensions does not hold valid for the other material.

Genitalia ( Figs. 11–12 ) with GL, 0.32–0.42 (30: 0.374), GPL, 0.035–0.050 (37: 0.0432). Dimensions: TW, 0.46–0.59 (36: 0.506); HL, 0.51–0.60 (36: 0.553); PW, 0.29–0.36 (36: 0.323); MW, 0.37– 0.46 (34: 0.410); AWV, 0.47–0.69 (32: 0.583); TL, 1.33–1.76 (33: 1.498).

Female. Abdomen as in Fig. 13 . Tergal setae: II, 2–4 (55: 2.9); III, 5–7 (31: 6.1); IV, 6–8 (29: 6.4); V, 6–8 (28: 6.6); VI, 6–8 (32: 6.8); VII, 5–9 (31: 7.3); VIII, 4–8 (32: 5.3). Sternal setae: II, 6–9 (18: 7.4); III, 6–8 (18: 7.0); IV, 5–9 (22: 6.8); V, 5–9 (25: 6.9); VI, 6– 9 (27: 7.3); VII, 6–10 (31: 7.0). Dimensions: TW, 0.49–0.64 (49: 0.568); HL, 0.55–0.66 (51: 0.605); PW, 0.31–0.38 (49: 0.354); MW, 0.41–0.54 (49: 0.464); AWV, 0.54–0.85 (45: 0.690); TL, 1.50–2.03 (48: 1.765).

Diagnosis. This species is very close morphologically to A. andigenae Carriker. However , both sexes have smaller dimensions, fewer sternal setae, and tergite II with only 2–4 setae (mean = 2.9), compared to A. andigenae with tergite II having 4–6 setae (mean = 4.4).
