Abstract

Abstract. The genus Lophotettix, belonging to the Neotropical subfamily Lophotettiginae of the family Tetrigidae, has hitherto been known only from five specimens, i.e. the holotypes of each of its five species. The most important diagnostic criterion for delimiting species was the morphology of the projection of the median carina of the pronotum, known as the crest. Gathered and examined are all the records of this genus in order to determine the intra- and interspecific morphological variability. The crest is found to be morphologically quite variable. In light of this finding, a taxonomic revision of the genus is performed in order to solve the now-apparent ambiguities. Within the genus Lophotettix, we defined two subgenera: (i) L. Lophotettix Hancock, 1909, a nominotypical subgenus, now encompassing L (L.) brevicristatus and L. (L.) zumbadoi, with the latter exhibiting marked variability, suggesting that it could be a complex of species, and (ii) L. Corticotettix Kasalo et Skejo subgen. nov. which encompasses L. (C.) alticristatus and the L. (C.) (unicristatus) species group with the species L. (C.) (u.) unicristatus and L. (C.) (u.) hancocki. An annotated key to the species of the genus Lophotettix is given.

中国蚱属的真实性质，1909(直翅目:蚱科):分类简编

摘要lophotetitix属属于蚱科lophotetitiginae新热带亚科，迄今为止仅从五个标本中得知，即其五个物种中的每个物种的全型。划分种的最重要的诊断标准是前凸中突的突起形态，即嵴。为了确定种内和种间的形态变异性，收集和检查了本属的所有记录。发现冠在形态上变化很大。根据这一发现，进行了属的分类修订，以解决现在明显的歧义。在Lophotettix属中，我们定义了两个亚属:(i) L. Lophotettix Hancock, 1909，一个命名典型的亚属，现在包括L (L.) brevicristatus和L (L.) zumbadoi，后者表现出明显的变异性，表明它可能是一个物种综合体;(ii) L. Corticotettix Kasalo et Skejo亚属。其中包括L. (c) alticristatus和L. (c) (unicristatus)物种组，以及L. (c) (u.) unicristatus和L. (C.) (u.) hancocki。给出了一份带注释的枇杷属的种检索表。
