( Figs. 13 –14View FIGURES 9 – 14, 20View FIGURES 15 – 21, 24–25View FIGURES 22 – 25)

Type host. Anabacerthia variegaticeps (Sclater, 1857)  —the Scaly-throated Foliage-gleaner ( Furnariidae  ).

Female (n = 1). Habitus as in Fig. 24View FIGURES 22 – 25. Hypopharynx fully developed, DHS 10, 0.07 long; DHS 11, 0.11 long. Gula with 4 setae on each side. Metanotum with 10 setae on posterior margin. Setae of femoral brush, 11–14. Metanotum and abdomen as in Fig. 13View FIGURES 9 – 14. Tergite I enlarged with medioposterior convexity resulting in distortion of tergites II –V. Tergite III with slender posterior detached plate bearing its medial postero-tergal pair of setae, and compressing tergites IV-V medially. Tergites VI –VIII unmodified and of similar size. With conspicuous median gap in each tergal setal row. Tergal setae: I, 14; II, 15; III, 12; IV, 13; V, 14; VI, 11; VII –VIII, 8. Postspiracular setae shortest (0.11–0.21) on III, V and VI, and extremely long (0.34–0.44) on I, II, IV, VII and VIII. Sternal setae: II, each aster of 5 setae, posterior margin with 14 and anteriorly with 10; III, 27; IV, 35; V, 28; VI, 24; VII, 16; VIII – IX with 6 marginal and 6 anterior setae. Each pleurite III –VII with about 5–6 short marginal setae. Anus with 34 ventral fringe setae, 31 dorsal. Dimensions: TW, 0.49; HL, 0.35; PW, 0.29; PSPL, 0.11; MW, 0.46; MSPL, 0.14; AWIV, 0.58; ANW, 0.22; TL, 1.51.

Male (n = 1). Habitus as in Fig. 25View FIGURES 22 – 25. Gula with 3 setae on each side. Metanotum with 10 setae on posterior margin, metasternal plate with 5 setae, as in Fig. 5View FIGURES 5 – 8. Setae of femoral brush, 13. Metanotum and abdomen as in Fig. 14View FIGURES 9 – 14. Tergal setae: I, 13; II, 14; III, 16; IV –V, 15; VI, 13; VII –VIII, 8. Conspicuous median gap in each tergal setal row. Postspiracular setae as for female. Sternal setae: II, each aster of 5 setae, posterior margin with 15 and anteriorly with 10; III, 21; IV –V, 31; VI, 24; VII, 14; VIII, 4. Genital sac sclerite similar to that of M. ochrolaemi  , much as in Fig. 12View FIGURES 9 – 14. Dimensions: TW, 0.47; HL, 0.33; PW, 0.31; PSPL, 0.11; MW, 0.41; MSPL, 0.14; AWIV, 0.52; GL, 0.44; GSL, 0.07; TL, 1.41.

Type material. Female holotype ( DNA voucher Mysp.Anvar.5.1.2006.4), ex Anabacerthia variegaticeps  , JMD 780 FMNH # 410612, Panama: Fortuna, 25 February 2006, K.P. Johnson coll. Paratype: 1 male, same data as holotype.

Remarks. The female of M. waterstoni  n. sp. can be easily distinguished from other species of Myrsidea  found on furnariids (e.g. M. strobilisternata  , M. calvi Sychra, 2007  , and M. ochrolaemi  ) by the presence of a detached plate on tergite III. In the male, the most distinctive morphological character is the chaetotaxy of tergites VII –VIII (see Figs. 15–17View FIGURES 15 – 21).

Etymology. This species is named after James Waterston (1879–1930), in honor of his description of the genus Myrsidea  .
