Description. Male. As in Fig. 12 View FIGURES 12–13 . Head structure, shape, and chaetotaxy as in Fig. 16 View FIGURES 16–20 ; s 3 View FIGURES 3–4 absent. Preantennal area comparatively slender. Antennae as in Fig. 16 View FIGURES 16–20 . Lateral margins of temples more or less straight, or only very weakly convex. Thoracic and abdominal segments, reticulation patterns, and chaetotaxy as in Fig. 12 View FIGURES 12–13 ; pronotum without prominent reticulation; pteronotum with intense reticulation centrally, but not laterally. Abdominal segment XI with large lateral lobes, much longer than abdominal segments IX+X. Stylus of subgenital plate does not reach distal margin of abdomen ( Fig. 14 View FIGURES 14–15 ). Male genitalia as in Figs 17–19 View FIGURES 16–20 . Basal apodeme slender, with slightly concave lateral margins and rounded proximal end. Mesosome ( Fig. 19 View FIGURES 16–20 , non-everted) slightly longer than broad, anterior margin deeply concave, distal and lateral margins with extensive, laterally continuous rugose area interrupted medianly; gonopore as in Fig. 19 View FIGURES 16–20 (non-everted). Parameres ( Fig. 18 View FIGURES 16–20 ) without both distinct lateral ridge and distinct twist; pst1 subterminal sensilla, pst2 subterminal microseta. Measurements in Table 2.

Female. As in Fig. 13 View FIGURES 12–13 . Head sensilla largely as in male, except s7–8 absent. Antennae as in Fig. 20 View FIGURES 16–20 . Thoracic and abdominal segments, reticulation patterns, and chaetotaxy as in Fig. 13 View FIGURES 12–13 . Ventral terminalia ( Fig. 15 View FIGURES 14–15 ) with anterior half of subgenital plate bearing a short median elongation on the posterior margin, and without a yoke-shaped thickening. Vulval margin u-shaped, widely and deeply concave. Subvulval plates with long, roughly triangular anterior ends. Measurements in Table 2.

Non-type material examined. Ex Meleagris gallopavo merriami   : 3♂, 3♀, Texas [ U.S.A.], Oct. 1900, R   . Meinertzhagen , bird 3148, NHMUK010682547 View Materials , NHMUK01068250 View Materials ( NHML)   . 1♂, 2♀, same data, bird ID 3147, NHMUK010682543 View Materials , NHMUK010682549 View Materials ( NHML)   .

Remarks. Considering that all nine specimens examined of Valimia polytrapezia   are mounted on slides containing type specimens of V. necopinata   (see details below, under Remarks of V. necopinata   ) we have marked all specimens of V. polytrapezia   with red dots on the slides.
