한라북방밑들이메뚜기 [=우리북방밑들이메뚜기]
Prumna halrasana (Lee and Lee 1984)
=Primnoa koreana Storozhenko 1991

몸길이는 약 25-30 ㎜이며 갈색과 밝은 황색이 어울린다. 앞날개는 암수 모두 퇴화하여 짧고 복부 고막 기관을 덮을 정도이다. 수컷 미모의 끝은 다소 부푼다. 주로 산지의 풀 숲이나 낮은 관목 위에서 발견된다. 제주도 한라산에서 처음 기록되었으나, 각지에서 널리 발견된다.

수컷 (Male)

Original description: Primnoa halrasana Lee and Lee 1984

  Description: Holotype Male. Body large. HEAD large, projects forward slightly. Antennae long, 22-segments, extend slightly beyond posterior margin of pronotum. Pronotum elongated; length of prozona of it 2 times that of metazona; median carina distinct, slightly elavated. TEGMINA narrow, slightly expanded apically, reach up to tympanic organ; length of tegmen 3 times its greatest width. LEG. Hind femora slender; length of femur 4 times its greatest width. Outer margin of hind tibia l0-spined, inner 11-spined. Prosternum with prominent, conical; process straight, with pointed apex. Mesosternum sparsely punctate; at its narrowest, interlobar space considerably less than its length. Metasternum sparsely punctate; its greatest width barely less than combined length of meso- and metasternum. ABDOMEN with sparse hair; last tergite small and pointed, contiguous at base. Supra-anal plate trapezoidal, apically slightly narrowed, lateral moderately emarginate edges with small indistinct medial denticles, posterior corners with a distinct long oblique pad and basal part with 3 longitudinal depressions; length of plate almost equals its greatest width; posterior corners rounded, apex of supra-anal plate rounded. CERCI in profile compressed apically; apex of cercus moderately oblique truncate, dorsally and ventrally rounded, do not reach apex of supra-anal plate. Subgenital plate very thick ended, deep round apical notch. Basic coloring brownish-black. Pronotum with 2 distinct blackish lateral dorsal stripes.

Endophallus sclerotized; basal valves of penis moderately small, at proximal ends excurved sideways; gonopore process present; ejaculatory duct with straight obtuse angle; apical valves strongly elongated and arcuated toward the rami, ivory-shaped. Epiphallus bridge-shaped. bridge strongly wide: ancorae short, angular, with acute apices inward; lophi tooth-like, contiguous to the base of lophi with well sclerotized membrane.
  Types examined: Holotype l♂, Mt. Halrasan, l700 m, 23. VII. l98l, Coll. Y.J. Kwon; Paratype l♂, 2♀♀. same date as holotype.
