민충이
Deracantha transversa Uvarov 1930

 

몸길이는 35-45 ㎜이며 쵸콜렛 빛깔이다. 행동이 민첩하지 못하고 어기적거리며 걸어다니므로 '민충이' 라는 이름이 붙었다. 눈 사이 간격이 넓고 더듬이는 겹눈 아래에 부착한다. 앞다리 고막은 째진 형이다. 날개는 매우 짧고 볼록하게 솟은 앞가슴등판 아래에 부분적으로 감추어져 있다. 수컷뿐만 아니라 암컷도 울 수 있다. 주로 강변이나 건조하게 마른 반사막과 같은 환경에 산다. 북한 북서부 평안도와 황해도에 서식한다.

 

Original description:
Deracantha transversa Uvarov 1930 Ann. Mag. Nat. Hist. (5)10: 255.

  Intermediate in size between D. onos Pallas, and D. grandis Lucas, but relatively more broad-shouldered than any of them, and apparently resembling in this respect the very poorly described D. cincta F. W.
  ♂ (type). Pronotum relatively large; its greatest width is two-thirds of its length. Prozona with the anterior margin concave; its disc transversely impressed; hind lateral angles well prominent, less obtuse than in D. onos or in D. grandis, with a distinct small circular pit at the base of the prominence. Metazona (i.e., the whole of the pronotum behind the constriction) scarcely longer than wide; lateral margins straight, tuberculate, with a minute spinule at the antero-lateral angle; hind margin of the disc straight in the middle, broadly rounded and with some obtuse conical tubercles on the sides; disc strongly wrinkled and punctured, with a deep and broad transverse impression in front of the middle, with a pair of deep irregularly shaped pits just behind the typical sulcus; the posterior portion of the metazona (lying behind the transverse impression) is distinctly broader than long, with a large transverse gibbosity and two broad, shallow, sublateral concavities behind the latter. Lateral lobes concave and minutely wrinkled in the metazona, smooth otherwise, much longer than deep; anterior margin slightly concave; lower margin straight in prozona, rounded-prominent opposite the lateral angle of the metazonal disc, broadly rounded in the rest. Abdominal tergites punctured, with the hind margins smooth, but not inflated. Last tergite with a pair of short conical appendages at the sides of the round median emargination. Cerci thick, with a conical tubercle on the inner margin behind the middle and a spinule on the inner side of the conical apical portion.
  General coloration brownish buff. Pronotum above blackish brown along the lateral margins, the colour extending more deeply inwards on the impressed portions of the disc; lateral lobes chocolate-brown, broadly pale below. Abdominal tergites with transversely placed black spots.
  ♀ (paratype). Pronotum relatively smaller than in the ma1e; tubercles and spinules on its margins more distinct and acute. Ovipositor nearly twice as long as the pronotum, moderately recurved.
  Total length, ♂ 44, ♀ 40; length of the whole pronotum, ♂ 18, ♀ 16; length of metazona, ♂ 13, ♀ 11; width of metazona, ♂ 12, ♀ 11; hind femur, ♂ 22, ♀ l7; ovipositor, ♀ 30 ㎜.
  Described from 2♂♂ and 5♀♀ from Peking.
  D. transversa, sp. n., is quite distinct from D. onos and D. grandis by the characters indicated above, as I am able to state after a direct comparison with the topotypical specimens of those two species. As regards D. cincta F. W., it has been very briefly described, so that a comparative study appears impossible. I tink myself justified, however, in expecting a species of Deracantha from Peking to differ from one described from Siberia. Judging by the figure of D. cincta, which is very poor, it appears that the latter species has a very short pronotum, but this may be due to a mistake of the artist.
