Myrsidea cinnamomei Dalgleish & Price, 2005

( Fig. 38–39 , 45 )

Type host. Pachyramphus cinnamomeus Lawrence, 1861 – the Cinnamon Becard ( Cotingidae ).

Female (n = 2). Habitus as in Fig. 38 . Hypopharynx fully developed, DHS10, 0.06 long; DHS11, 0.10 long. Gula with 5 setae on each side. Metanotum with 11–13 setae on posterior margin. Setae of femoral brush, 23–25. Tergite I enlarged with broadly rounded medioposterior prolongation resulting in distortion of tergites II–IV. Tergites V–VIII unmodified and of similar size. With conspicuous median gap in each tergal setal row. Tergal setae: I, 14–19; II, 17–18; III, 16–18; IV, 17–18; V, 15–16; VI, 11–14; VII, 8–11; VIII, 8. Postspiracular setae shortest (0.17–0.19) on III, V and VI, and extremely long (0.28–0.54) on I, II, IV, VII and VIII. Sternal setae: II, each aster of 4 setae (one specimen with 5 on both sides), posterior margin with 19 and anteriorly with 7; III, 23–26; IV, 37– 40; V, 43–45; VI, 34–38; VII, 14–17; VIII–IX with 11–13 marginal and 9–10 anterior setae. Each pleurite III–VII with about 6–10 short marginal setae. Anus with 37 ventral fringe setae, 36–41 dorsal. Dimensions: TW, 0.45– 0.48; HL, 0.34–0.35; PW, 0.30; PSPL, 0.12–0.13; MW, 0.46–0.47; MSPL, 0.18; AWIV, 0.60–0.63; ANW, 0.23– 0.25; TL, 1.57–1.62.

Male (n = 1). Habitus as in Fig. 39 . Gula with 5 setae on each side. Metanotum with 10 setae on posterior margin, metasternal plate with 6 setae. Setae of femoral brush, 20–21. Tergal setae: I, 10; II–III, 16; IV, 14; V, 16; VI, 15; VII, 12; VIII, 8. Conspicuous median gap in each tergal setal row. Postspiracular setae as for female. Sternal setae: II, each aster of 4 setae (rarely 5 on one side), posterior margin with 14 and anteriorly with 8; III, 21; IV, 34; V, 37; VI, 31; VII, 19; VIII, 6. Genital sac sclerite as in Fig. 45 . Dimensions: TW, 0.44; HL, 0.30; PW, 0.29; PSPL, 0.11; MW, 0.40; MSPL, 0.15; AWIV, 0.47; GL, 0.43; GSL, 0.10; TL, 1.36.

Material examined. 1 male and 1 female (female DNA voucher Mysp.Pahom.4.24.2006.4), ex Pachyramphus homochrous Sclater, 1859 , GMS 1814, Panama: Lago Bayano, 16 February 2006, K.P. Johnson coll. 1 female, same data, except GMS 1815.

Remarks. This species was described by Dalgleish & Price (2005) from 8 specimens collected on Pachyramphus cinnamomeus from Costa Rica. It is herein redescribed to add new data based on material from an additional host species, in particular the variability in the shape of the genital sac sclerite of the male (compare Fig. 45 with fig. 3 in Dalgleish & Price 2005). In other aspects, our 3 specimens from P. homochrous agree with the original description of M. cinnamomei . This sample represents a new host-association and a new geographical record for this louse species.
