7. Austrophilopterus thysi Price and Weckstein , new species ( Figs. 15–16 )

Type host. Selenidera gouldii (Natterer) , Gould’s Toucanet.

Type material. Holotype male, 1 male, 2 female paratypes, BRAZIL: Mato Grosso, W bank Rio Teles Pires, across from mouth of Rio Cristalino, 32 km NE Alta Floresta, 0 9 38'01"S, 55 56'21"W, 8 July 1999 (JDW­222). All specimens deposited in the National Museum of Natural History, Washington, DC.

Male. Terminal abdominal segments as in Fig. 15 , dorsal head as in Fig. 16 . Tergal setae: II, 3; III–VII, 6; VIII, 4. Sternal setae: II, 6; III, 4–6; IV–VI, 4; VII, 3–4; VIII, 2. Genitalia essentially as in Figs. 11–12 , with GL, 0.39–0.41, GPL, 0.035–0.040. Dimensions: TW, 0.51–0.56; HL, 0.54; PW, 0.32–0.33; MW, 0.44–0.47; AWV, 0.58–0.68; TL, 1.54–1.58.

Female. Tergal setae: II, 2; III–IV, 5–6; V, 5; VI, 5–6; VII, 6–7; VIII, 4–5. Sternal setae: II, 6; III, 4–6; IV, 4; V, 4–6; VI, 4–5; VII, 6–7. Dimensions: TW, 0.57–0.60; HL, 0.57–0.59; PW, 0.35–0.36; MW, 0.50–0.51; AWV, 0.69–0.73; TL, 1.83–1.84.

Diagnosis. This species is unique in that it combines the posteriorly rounded dorsoanterior head plate ( Fig. 16 ) of the cancellosus species group with the distinctive genitalic type and other features of the truncatus species group. In spite of this discrepancy of head plate type, A. thysi is placed in this species group because of the similarity of all other features to its members.

Etymology. This species is named for Mathys (“Thys”) J. Meyer, Illinois Natural History Survey, Champaign, in recognition of his deep interest in the intricacies of taxonomic research on both frogs and chewing lice.
