Oxylipeurus burmeisteri (Taschenberg, 1882); Price et al. 2003: 202 (in partim).
Type host. Lophophorus sclateri sclateri Jerdon, 1870 —Sclater’s monal.
Type locality. Yunnan Province, China.
Diagnosis. Cataphractomimus impervius is most similar to C. mirapelta, based on the larger size of these two species compared to the other species in the genus (Table 1; C. burmeisteri is also smaller), as well as their proportionately larger scapes (compare Figs 21–22 with Fig. 23). However, C. impervius and C. mirapelta can be separated by the following characters: Inter-tergal plates absent in male C. impervius (Fig. 1) but present in male C. mirapelta (Fig. 3); male tergopleurite XI medianly separate in C. impervius (Fig. 1) but medianly continuous in C. mirapelta (Fig. 3); subgenital plate proportionately narrower and with a more slender and gently tapering stylus in C. impervius (Fig. 76) than in C. mirapelta (Fig. 77); rugose area of male antennae more extensive in C. mirapelta (Fig. 22) than in C. impervius (Fig. 21); ventral sclerite of male mesosome clearly delimited laterally and with roughly triangular shape in C. impervius (Fig. 35) but diffuse laterally and with more or less flat anterior margin in C. mirapelta (Fig. 38); parameres longer and more slender in C. impervius (Fig. 34) than in C. mirapelta (Fig. 37); antero-lateral extensions of mesosome with smoothly rounded anterior margins in C. impervius (Fig. 35), but with more angular anterior margin in C. mirapelta (Fig. 38).
Description.
Both sexes. Head shape, structure, reticulation, and chaetotaxy as in Figs 1–2; dorsal preantennal suture not visible in examined specimens. Marginal carina narrow. Head sensillus s5 situated about as far from pns as from s3. Thoracic and abdominal plates, chaetotaxy and approximate reticulation patterns as in Figs 1–2. Pronotum with deep anterior incision along midline (Fig. 1). Inter-tergal plates and internal anterior bulges absent. Tergopleurite XI medianly separate.
Male. Antenna as in Fig. 21; rugose area limited to flagellomere I. Subgenital plate formed from sternal plate IX+X only, separate from sternal plate VIII (Fig. 76); reticulation of subgenital plate incomplete medianly; stylus slender (Fig. 76). No lateral sternal plates on abdominal segment XI. Basal apodeme as in Fig. 33, widening gradually towards distal end. Ventral sclerite of mesosome roughly triangular, separate from mesosome, with several small pores visible near lateral ends (Fig. 35). Rugose area of mesosome extensive. Antero-lateral extensions of mesosome with smooth anterior margins. Parameres elongated, slender (Fig. 34). Measurements as in Table 1.
Female. Antennae as in Fig. 2. Subgenital plate medianly continuous (Fig. 69), but with deep anterior incision along midline. Lateral accessory vulval plates with 1–2 microsetae proximally on each side; vulval margin with 13– 17 marginal and submarginal setae on each side (exact position often hard to establish, and therefore here counted together). Subvulval plates slender, not extending much below vulval margin. Measurements as in Table 1.
Etymology. The specific epithet is from “ impervius ”, Latin for “impassable”, referring to the extensive “armour” of the species.
Type material. Holotype ♂, Yunnan [China], May 1906, R. Meinertzhagen, 3626, NHMUK010682345 (NHML) [only specimen on slide with intact stylus and antennae, lower row, marked with red dot on slide]. Paratypes: 6♂, 8♀, same data as holotype, NHMUK010682343, NHMUK010682345–6 (NHML).
