Type host: Meleagris gallopavo merriami Nelson, 1900 —turkey.

Type locality. Texas, United States .

Description. Male. As in Fig. 1 . Head structure, shape, and chaetotaxy as in Fig. 5 ; s 3–4 and s 8 absent. Preantennal area comparatively broad. Antennae as in Fig. 5 . Lateral margins of temples clearly convex. Thoracic and abdominal segments, reticulation patterns, and chaetotaxy as in Fig. 1 ; pronotum with transverse band of intense reticulation in anterior half; pteronotum with median section less intensely reticulated. Abdominal segment XI with large lateral lobes, slightly longer than abdominal segments IX+X. Stylus of subgenital plate extends beyond distal margin of abdomen ( Fig. 3 ). Male genitalia as in Figs 7–10 . Basal apodeme slender, with slightly concave lateral margins and diffuse proximal end. Mesosome ( Fig. 9 , non-everted) long, anterior margin deeply concave, distal and lateral margins with extensive, laterally continuous rugose area interrupted medianly; gonopore as in Fig. 9 (noneverted) and Fig. 10 (everted). Parameres ( Fig. 8 ) with distinct lateral ridge except on anterior end; and a distinct twist on distal third; pst1 not visible, pst2 terminal microseta. Measurements in Table 2.

Female. As in fig. 2. Head sensilla largely as in male, except s7, s9 absent. Antennae as in Fig. 6 . Thoracic and abdominal segments, reticulation patterns, and chaetotaxy as in Fig. 2 . Ventral terminalia as in Fig. 4 . Anterior half of subgenital plate with a median posterior elongation and a distal yoke-shaped thickening with less distinctly sclerotised postero-lateral extensions. Vulval margin u-shaped, narrowly and deeply concave. Subvulval plates with short, slender anterior ends. Measurements in Table 2.

Figures

FIGURES 1–2. Valimia corpulenta. 1, male habitus, dorsal and ventral views. 2, female habitus, dorsal and ventral views. For clarity, the reticulation of the female gonapophyses is shown only partially; in examined specimens, this reticulation covers more or less all of the plates.

FIGURES 3–4. Valimia corpulenta. 3, male subgenital plate and terminalia, ventral view. 4, female subgenital plate and terminalia, ventral view. For clarity, the reticulation of the female gonapophyses is shown only partially; in examined specimens, this reticulation covers more or less all of the plates.

FIGURES 5–10. Valimia corpulenta. 5, male head, dorsal and ventral views. 6, female antenna, ventral view. 7, male genitalia, dorsal view, non-everted genitalia. 8, male mesosome, ventral view, non-everted genitalia. 9, male mesosome, ventral view, everted genitalia. 10, male paramere, dorsal view. Female antennae drawn at same scale as head. Paramere drawn at same scale as full genitalia. Abbreviations: pas = pre-antennal seta; pns = postnodal seta; pts = post-temporal seta; s = sensillus 1–9.
