Turdinirmoides rozsai Gustafsson, Zou & Bush , new species

( Figs 27–33 )

Type host. Carpodacus subhimachala (Hodgson 1836) —crimson-browed finch ( Fringillidae ).

Type locality. Sakhuwasabha District , Nepal .

Diagnosis. Turdinirmoides rozsai n. sp. is most similar to T. janigai n. sp. For a comparison between these species, see T. janigai above.

Description. Both sexes. Head subtriangular, broad and rounded ( Fig. 29 ), with lateral margins of preantennal area convex, and frons shallowly concave medianly. Marginal carina interrupted laterally. Dorsal preantennal suture extends slightly median to ads. Dorsal anterior plate with sinuous thickening at about mid-length. Ventral anterior plate present. Head chaetotaxy as in Fig. 29 . Coni short, broad. Temples rounded. Gular plate spade-shaped, with convex lateral margins. Thoracic and abdominal segments as in Figs 27–28 .

Male. Subgenital plate divided into sternal plate VII and subgenital plate covering segments VIII–XI. Thoracic and abdominal chaetotaxy as in Fig. 27 ; tps absent on all tergopleurites; sts present on male sternite VII; abdominal setae in general short. Basal apodeme ( Fig. 30 ) narrowing markedly anteriorly. Proximal mesosome ( Fig. 32 ) with irregular lateral and anterior margins. Mesosomal lobes broad, rounded, with anterior hook and fringed distal ends; 3 gpmes microsetae on each side of gonopore; 2 lpmes on each side on posterior margin of lobes; gonopore roughly T-shaped, with broad triangular antero-lateral extensions and shallow anterior margin. Parameral heads ( Fig. 31 ) bifid, and blades roughly oval; pst1 sensillum, central; pst2 microsetae, on distal margin. Measurements (n = 1): TL = 2.13; HL = 0.46; HW = 0.45; PRW = 0.27; PTW = 0.42; AW = 0.53.

Female. Thoracic and abdominal chaetotaxy as in Fig. 28 ; ps present on female abdominal segment III. Subgenital plate ( Fig. 33 ) pentagonal, overlapping distally with detached cross-piece, but not fused to this; detached cross-piece follows vulval margin for entire length. Vulval margin ( Fig. 33 ) slightly concave medianly, with 5 short, slender vms on each side, and 5–6 short, thorn-like vss on each side; 6 long, slender vos on each side; distal 2 vos on detached cross-piece, median to vss. Measurements (n = 1): TL = 2.56; HL = 0.48; HW = 0.51; PRW = 0.30; PTW = 0.46; AW = 0.66.

Type material. Ex Carpodacus subhimachala : Holotype ♂, Sankhuwasabha District, [Kosi Zone, Eastern Region,] Nepal, 3 Aug. 1973, HE-0658 ( NHML). Paratype: 1♀, same data as holotype ( NHML) .

Etymology. The species epithet honours our friend and colleague Dr Lajos Rózsa (MTA Centre for Ecological Research, Hungarian Academy of Sciences, Tihany, Hungary), in recognition of his many varied, novel and thought-provoking contributions to the study of Phthiraptera .
