Abstract

A remarkable characteristic of katydids (Orthoptera, Tettigoniidae) is the elongated ovipositor, which is associated with oviposition behavior. The high degree of complexity of both sclerites and muscles arrangement of the ovipositor, is only similar to the ovipositor of Hymenoptera. Here we describe the morphology of the ovipositor within Tettigoniidae, and add descriptions of known oviposition behavior. Fifteen skeletal structures can be recognized, of these, three pairs of muscles are new while nine pairs were already described in the literature. The new muscles are ap2vf, anterior projection of second valvifer; bcov, blade complex of the ovipositor; and dbl, dorsal blade. The morphology of the ovipositor blade complex (bcov), the shape of the first valvifer (1vf), posterior intervalvular sclerite (piv), tergite IX (T9), anterior projection of the second valvifer (ap2vf), and the second valvifer (2vf), and their related muscles affect oviposition in Tettigoniidae. This contribution helps to understand katydid's oviposition behavior. Additionally, the new descriptions help in the search for new characters in Tettigoniidae.

故事的刀刃:基于 Tettigoniidae(昆虫纲,直翅目,鞘翅目)产卵器形态了解产卵行为的进化特征
螽斯(直翅目,Tettigoniidae)的一个显著特征是拉长的产卵器,这与产卵行为有关。产卵器的硬骨和肌肉排列高度复杂,仅与膜翅目的产卵器相似。在此,我们描述了 Tettigoniidae 的产卵器形态,并补充描述了已知的产卵行为。我们可以识别出 15 个骨骼结构,其中有 3 对肌肉是新的,而 9 对已经在文献中描述过。新的肌肉包括:ap2vf,第二瓣膜的前突起;bcov,产卵器的叶片复合体;dbl,背侧叶片。产卵器叶片复合体(bcov)的形态、第一瓣膜(1vf)的形状、后间室硬片(piv)、第九节叶(T9)、第二瓣膜的前部突起(ap2vf)和第二瓣膜(2vf)及其相关肌肉都会影响 Tettigoniidae 的产卵。这有助于理解螽斯的产卵行为。此外,新的描述有助于寻找螽斯科的新特征。

期刊介绍: Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged.
