Female (3). Gula with 4–5 setae on each side. Metanotum, dorsal abdomen, and ventral terminalia as in Fig. 39 . Metanotum not enlarged, with 12–15 marginal setae; metasternal plate with 4–6 setae. Abdominal tergites unmodified, with slight medioposterior curvature associated with III–IV. Tergal setae, with median gap on III– VIII: I, 14–16; II, 17–18; III–V, 14–17; VI, 12–14; VII, 9–11; VIII, 8. Postspiracular setae long on V–VI (0.16–0.21), extremely long on VII (0.34–0.40). Sternal setae: II, 3–4 in each aster, 11–13 marginal between asters, 6–9 anterior; III, 21–24; IV–V, 30–38; VI, 19–26; VII, 12–14; VIII–IX, 16–19. Dimensions: TW, 0.40– 0.42; HL, 0.27–0.30; PW, 0.27–0.28; MW, 0.41–0.46; AWIV, 0.61–0.65; ANW, 0.19–0.24; TL, 1.45–1.56.

Male (3). Gula with 4–5 setae on each side. Metanotum and dorsal abdomen much as in Fig. 42 . Metanotum with 11–12 marginal setae; metasternal plate with 5 setae. Tergal setae, with median gap on posterior segments: I, 15–16; II, 21–22; III, 19–20; IV, 18–19; V–VII, 16–18; VIII, 12–14. Sternal setae: II, 3–4 in each aster, 10–12 marginal between asters, 8–10 anterior; III, 19–24; IV–V, 35–38; VI, 24–29; VII, 14–16; VIII, 4– 5. Dimensions: TW, 0.37–0.39; HL, 0.27–0.28; PW, 0.24–0.26; MW, 0.35–0.39; AWIV, 0.49–0.52; GL, 0.39– 0.43; TL, 1.20–1.35.

Material examined. 3 females, 3 males, ex Emberiza citrinella calliginosa Clancey , NEW ZEALAND (3 collections).

Remarks. This is an atypical species of Myrsidea in that it is the only one reported from this genus by Price et al. (2003) to occur on hosts in two different passerine families -- the Fringillidae and the Emberizidae . Klockenhoff (1984) redescribed this species and recorded it from one species of Serinus each from Morocco and New Zealand, one of Carduelis each from Spain and New Zealand, and one of Emberiza from New Zealand. The detailed description is excellent and is accompanied by fine illustrations. Our descriptive details for M. serini are based only on the material we have studied from E. citrinella . Since the other specimens included in this louse taxon by Klockenhoff (1984) are in the Fringillidae and beyond the scope of this paper, we tentatively accept these also as M. serini .
