Osculonirmus limpidus Mey, 1982 

( Figs 122–129View FIGURES 122 – 123View FIGURES 124 – 129)

Osculonirmus limpidus Mey, 1982a: 60  .

Brueelia limpidus (Mey, 1982)  ; Price et al. 2003: 156.

Type host. Eremophila alpestris brandti (Dresser, 1874)  —horned lark.

Type locality. 15 km W of Chovd-chot , Aimak Chovd, Mongolia. 

Other hosts. Eremophila alpestris adusta (Dwight, 1890)  —horned lark new host record. Eremophila alpestris albigula (Bonaparte, 1850)  —horned lark new host record. Eremophila alpestris utahensis (Behle, 1938)  —horned lark new host record.

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 124View FIGURES 124 – 129. Displacement of marginal carina at osculum generally deeper in females than in males. Thoracic and abdominal segments as in genus description and Figs 122–123View FIGURES 122 – 123.

Male. Scape swollen ( Fig. 124View FIGURES 124 – 129). Abdominal chaetotaxy as in Table 2 and Fig. 122View FIGURES 122 – 123. Male genitalia distinct ( Fig. 126View FIGURES 124 – 129). Basal apodeme long, slender. Proximal mesosome elongated, slender. Gonopore ( Fig. 127View FIGURES 124 – 129) narrowly open distally, anterior end pointed, distal ends widened and slightly elongated. Mesosomal lobes small, rounded. Parameral heads ( Fig. 128View FIGURES 124 – 129) swollen, deeply bifid. Parameral blades much elongated, convergent distal to mesosome and distal parts close together; pst1 sensilla, near distal tip; pst2 microseta, lateral near distal tip. Measurements ex Eremophila alpestris adusta  (n = 1): TL = 1.47; HL = 0.37; HW = 0.31; PRW = 0.18; PTW = 0.33; AW = 0.44. Ex E. a. utahensis  (n = 3 except n = 2 for TL and AW): TL = 1.47–1.48; HL = 0.36–0.37; HW = 0.30–0.32; PRW = 0.14–0.17; PTW = 0.27–0.29; AW = 0.35–0.41.

Female. Antennae as in Fig. 125View FIGURES 124 – 129. Abdominal chaetotaxy as in Table 2 and Fig. 123View FIGURES 122 – 123. Subgenital plate oval to rounded triangular, not approaching vulval margin ( Fig. 129View FIGURES 124 – 129). Vulval margin narrowly convex ( Fig. 129View FIGURES 124 – 129), with 3 short, slender vm on each side, and 2 short, thorn-like vss on each side; 2 short, slender vos on each side. Measurements ex Eremophila alpestris adusta  (n = 9): TL = 1.86–2.09; HL = 0.41–0.43; HW = 0.35–0.37; PRW = 0.19; PTW = 0.31–0.35; AW = 0.41–0.51. Ex E. a. albigula  (n = 9): TL = 1.67–2.02; HL = 0.41–0.43; HW = 0.35– 0.38; PRW = 0.18–0.20; PTW = 0.30–0.36; AW = 0.39–0.52. Ex E. a. utahensis  (n = 14 except n = 2 for AW): TL = 1.79–1.97 (1.89); HL = 0.40–0.43 (0.42); HW = 0.34–0.38 (0.36); PRW = 0.16–0.20 (0.18); PTW = 0.31–0.36 (0.33); AW = 0.40–0.46 (0.43).

Remarks. Our material from North American hosts differs from that illustrated by Mey (1982a) in the shape of the head and the pterothorax, but chaetotaxy and other characters appear to be the same. We have not seen any material from the type host subspecies, and cannot assess whether the apparent differences are between the actual specimens or in how they are illustrated. The tergopleurites are not medianly continuous in any material examined by us, unlike Mey’s (1982a: fig. 1) illustration.
