 Oxylipeurus polytrapezius polytrapezius (Burmeister); Clay 1938: 181, figs 37a, 37c, 39b; pl. XII, fig. 4.   
 Reticulipeurus polytrapezius (Burmeister); Kéler 1958: 332.   
 Oxylipeurus polytrapezius (Burm., 1838); Price et al. 2003: 204.   
 Type host: Meleagris gallopavo Linnaeus, 1758 —turkey.   
 Type locality. None given.   
  Description. Male.  As in Fig. 12. Head structure, shape, and chaetotaxy as in Fig. 16; s 3 absent. Preantennal area comparatively slender. Antennae as in Fig. 16. 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; 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). Male genitalia as in Figs 17–19. Basal apodeme slender, with slightly concave lateral margins and rounded proximal end. Mesosome (Fig. 19, 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 (non-everted). Parameres (Fig. 18) without both distinct lateral ridge and distinct twist; pst1 subterminal sensilla, pst2 subterminal microseta. Measurements in Table 2.   
 Female. As in Fig. 13. Head sensilla largely as in male, except s7–8 absent. Antennae as in Fig. 20. Thoracic and abdominal segments, reticulation patterns, and chaetotaxy as in Fig. 13. Ventral terminalia (Fig. 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, NHMUK01068250 (NHML). 1♂, 2♀, same data, bird ID 3147, NHMUK010682543, NHMUK010682549 (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.
