Original description:
Loxoblemmus spectabilis Gorochov and Kostia 1993 Acta Zool. Cracov. 35(3): 428, figs. 3, 4, 6.

  Male (holotype). Size as in previous species. Head with broad, but not short face, distinctly broadened beneath the eyes. Rostrum relatively large and convex. Morphologcal details of the surface of face similar to L. coreanus. Head dark-brown with pale pattern on the upper side and with large mark in area of median ocellus and marks on mandibles and labrum. Antennae brownish with pale marks on scapus. Scapus with small, but distinct process at the apex. Palpi as in previous species (length of last segment of maxillary and labial palpi respectively 2.8 ㎜ and 1.8 ㎜). Pronotum typical of the genus, is sides distinctly diverging anteriorly, with dark-brown lateral lobes (only their anterior part along lower edge with very small, pale longitudinal mark). Disk of pronotum covered with dark-brown and lighter mark. Tegmina visibly shorter then abdomen. Venation of tegmina as in Fig. 6. Stridulatory organ with 4 oblique veins. Apical field relatively short. Coloration of dorsal surface of tegmina like that in previous species. Lateral field dark-brown in upper half and nearly transparent with pale greyish veins in lower half. Legs and abdomen as in previous species. Median part of posterior margin of epiphallus weakly produced and not deeply incised.
  Variation. Allometric variation the same type as observed in
L. coreanus. However, the variation in the shape of the anterior margin of rostrum is also remarkable. The anterior margin can be slightly curved and even with small excision in the middle. Stridulatory organ sometimes with 3 oblique veins.
  Female. General coloration like that in the male, only the pale transverse band above the base of antennae is not broad, and the pale mark in the area of median ocellus not large. Apart from general coloration it differs from the previous species in its shortened tegmina, reaching the 5th or 6th tergit of abdomen and in ovipositor, which is as long as the hind femur.
  Length. Body size of male 18 ㎜, female 15-16 ㎜; pronotum of male 2.7-2.9 ㎜, female 2.8-3 ㎜; tegmina of male 7-7.5 ㎜, female 6.3-6.5 ㎜; hind femur of male 9.2-9.5 ㎜, female 9.8-10.3 ㎜; ovipositor 9.8-10.3 ㎜.
  Material. North Korea: Chagang-do prov., Kujang (39°52'/126°04') 26 VIII 1990, 3♂ (including holotype), 3♀, coll. D. KOSTIA, E. WARCHALOWSKA & A. NADACHOWSKA. All materials are deposited in the Institute of Systematics and Evolution of Animals, Polish Academy of Science, Cracow (holotype♂ and 2 paratypes-2♀) and in the Zoological Institute of the Academy of Sciences, St. Petersburg (paratypes -1♂ and 1♀).
  From all known species of the genus, except
L. animae BHOWM., it can be distinguished by the pale coloration of the dorsal anterior margin of rostrum in males. From L. animae BHOWM. it differs in the shape of the antennal process, which is short and not bent.
