The synonymy of Xenophyes forsteri with X. cascus is confirmed. Illustrated descriptions and identification keys are provided for the adult and the last instar. The male aedeagus is recognised as the most important structure to diagnose species. Other useful morphological characters include body shape, head, pronotum, and tegmina expressed as length and width measurements. The Principal Component Analysis (PCA) shows that five species are well separated from each other, but X. goniomus greatly overlaps with X. cascus, X. kinlochensis, and X. rhachilophus. There is also broad morphometric overlap between North Island and South Island specimens of X. cascus, confirming their conspecificity. Results from a Canonical Variate Analysis (CVA) determined which morphometric characters are most suitable for use in keys and descriptions. X. cascus is the only species occurring on both the North and South Islands. Other species are restricted to the South Island.

Within this framework, we also considered the genera Afrodrepanus Krikken, 2009 (two species) and Drepanocerus Kirby, 1828 (two species) employing sets of traits from external morphology, the genitalia of both sexes and the epipharynx. The genus Cyptochirus Lesne, 1900 was chosen as an outgroup. A new species-Tibiodrepanus tagliaferrii sp. nov.-was described based on four females from Cameroon and Namibia. The phylogenetic analyses confirmed that the Tibiodrepanus and Sulcodrepanus species were closely related, yet it did not support the hypothesis of a generic or subgeneric separation of the two taxa. Hence, we establish Sulcodrepanus as a junior synonym of Tibiodrepanus, new synonymy. The genus Tibiodrepanus shows a disjunct Afrotropical-Oriental (common to many other Drepanocerina genera) and Southeastern Palaearctic (Hindu Kush, Afghanistan) distribution pattern.

In addition, the genus Bhatasca Dworakowska, 1995 is newly recorded from the Chinese mainland and a new species, B. rectangulata Qin & Zhang, sp. n., is described. The genus Ghauriana Thapa, 1985 is reported for the first time from China and a new species, G. sinensis Qin & Zhang sp. n. is added to the Chinese typhlocybine fauna. Keys to all species in each genus are given. Habitus photos and illustrations of male genitalia of these new species are also provided.

The new species lacks a pseudonychium on the ungues, has a smaller mucro than the other species in the genus, and females have long anal appendices. A key to identify the three species known in the family is provided.
查看更多>>摘要：In order to decipher biodiversity, we need to maintain and improve the descriptive scope by pursuing the fundamental ontology and conceptual foundations. Descriptive morphology is currently the clearest avenue to conceiving, understanding and conceptually conveying species as units of evolution and ecology (Serna and Mackay 2010; Wheeler 2008 and references therein). Morphological descriptions ought to be independent of homology as explanatory mechanisms (Vogt 2008). Although essential to providing conceptual criteria for choosing and delimiting morphological units, homology does not require morphological terms to be defined in reference to it (Vogt et al. 2010). Ant morphology and its associated terminology demands intensive studies in order to unify criteria for the basic descriptive and comparative work (Serna and Mackay 2010).
