애여치
Eobiana engelhardti (Uvarov 1926)

 

몸길이는 약 22-25 ㎜이며 갈색형과 부분적인 녹색형이 있다. 앞날개는 복부의 중간을 약간 더 덮는 정도로 짧은 중시형이 보통이나, 간혹 환경 조건에 따라 장시형이 나타난다. 앞날개 끝은 중시형에서 뾰족하지만 장시형에서는 둥글다. 평지의 물가 초원이나 습지 부근 등에서 국지적으로 발견된다. 일본, 러시아에도 분포한다.

Original description:
Metrioptera engelhardti Uvarov 1926 Ann. Mag. Nat. Hist. 9(17): 281, fig. 7.

  ♀. Similar in size and in habitus to M. albopunctata Goeze (=grisea F.). Head small, pronotum covering it almost to the eyes. Fastigio-frontal suture scarcely longer than the width of the first antennal joint. Pronotum relatively shorter and broader than in M. albopunctata; its base scarcely narrowed anteriorly, practically flat and smooth in prozona, very slightly impressed and distinctly punctured in metazona; hind margin very broadly rounded; lateral keels very much rounded; median keel distinct in metazona, faintly indicated in prozona; lateral lobes less high than in M. albopunctata, with the anterior margin more oblique. Prosternum unarmed. Mesosternal lobes much longer than at the base, broad, their apical angles about 30°. Metasternal lobes not longer than broad, their apical angles straight. Elytra extending well beyond the hind knees. Hind femora relatively shorter than in M. albopunctata and more suddenly attenuate behind the middle, coarsely punctured above. Last sternites without any peculiar structures. Subgenital plate unusually narrow and long, covering the basal fourth of ovipositor; its lower surface finely keeled along the middle, slightly impressed sideways; apex narrow, deeply and very acutely excised; apical lobes lying very closely to sides of ovipositor, with the inner margins rounded, the outer margins straight, and the apical angles  slightly less than 90°. Ovipositor like that of M. albopuntata, but more strongly narrowed in tile apical half.
  Coloration castaneous, shiny. Head with shining black postocular fasciae, and an indefinite blackish median fascia on the occiput, including a fine pale line. Mandibulae black, with brown apices. Pronotal lateral lobes shiny blackish-castaneous, quite black above, very narrowly and not sharply marginated with pale posteriorly and (less distinctly) anteriorly. Elytra smoky, with indefinite castaneous spots. Wings distinctly infumate towards the apices. All femora black above, the hind ones black externally as well, getting paler in the attenuate part, but the knees are blackened.
  Length of body 17; pronotum 6; elytra 27.5; hind femur l9; ovipositor 10 ㎜.
  Another female (paratype) is of a pale coloration, with the black colour less spread, but otherwise not distinct from the type.
  Named after Mr. V.M. Engelhadt, ardent naturalist and painstaking observer, who collected it.
  Although I compare this fine new species with M. albopunctata Goeze (=grisea, F.), I do so only in order to make clear its chief characters, but not to indicate the relationship. Indeed, I think that M. engelhardti is nearer to the group brachyptera-roeseli than to M. albopunctata; this question, however, cannot be settled until the male is known.
  The new species is very easily recognisable by the highly peculiar shape of the female subgenital plate, by the pronotum not narrowed anteriorly, and by its coloration.
