Abstract

The weevil subtribe Listroderina belongs in the tribe Rhytirrhinini (subfamily Cyclominae), and has 25 genera and 300 species in the Americas. A cladistic analysis of the American genera was undertaken, using 53 characters from the external morphology, mouthparts, body vestiture, and male and female genitalia, and considering Rhigopsidius Heller (subtribe Rhytirrhinina) as the outgroup. The analysis yielded 20 equally parsimonious cladograms (108 steps, CI=0.42, RI=0.64), which after successive weighting resulted in three minimum-length cladograms (256 steps, CI=0.67, RI=0.82). In the strict consensus cladogram, which has the same topology as one of the original cladograms, the genera follow the sequence (Philippius, (Trachodema, (Lamiarhinus, (Acrorius, (Acroriellus, ((Rupanius, (Adioristidius, Amathynetoides, (Puranius, (Macrostyphlus, Andesianellus)))), (Hyperoides, (Germainiellus, (Antarctobius, Nacodius)), ((Haversiella, (Listronotus, Neopachytychius)), (Listroderes, Acrostomus), (Falklandiellus, (Falklandiopsis, (Telurus, (Falklandius, Lanteriella)))))))))))). A phylogenetic classification for the genera of American Listroderina is proposed, where the five principal lineages are recognized as generic groups:Macrostyphlus group (Rupanius, Adioristidius, Amathynetoides, Puranius, Macrostyphlus, and Alndesianellus),Antarctobius group (Germainiellus, Antarctobius, and Nacodius),Listronotus group (Haversiella, Listronotus, and Neopachytychius),Listroderes group (Listroderes and Acrostomus), and Falklandius group (Falklandiellus, Falklandiopsis, Telurus, Falklandius, and Lanteriella).

摘要

象鼻虫亚族Listroderina属于Rhytirrhinini族（Cyclominae亚科），在美洲有25个属和300个物种。利用来自外部形态、口器、体表覆盖物以及雄性和雌性生殖器的53个特征，以Rhigopsidius Heller（Rhytirrhinina亚族）作为外类群，对美洲的属进行了分支系统分析。该分析产生了20个同等简约的分支图（108步，一致性指数CI = 0.42，保留指数RI = 0.64），经过连续加权后得到三个最小长度的分支图（256步，CI = 0.67，RI = 0.82）。在严格合意分支图中（其拓扑结构与原始分支图之一相同），各属的排列顺序如下：（Philippius，（Trachodema，（Lamiarhinus，（Acrorius，（Acroriellus，（（Rupanius，（Adioristidius，Amathynetoides，（Puranius，（Macrostyphlus，Andesianellus）））），（Hyperoides，（Germainiellus，（Antarctobius，Nacodius））），（（Haversiella，（Listronotus，Neopachytychius）），（Listroderes，Acrostomus），（Falklandiellus，（Falklandiopsis，（Telurus，（Falklandius，Lanteriella）））））））））。提出了美洲Listroderina属的系统发育分类，其中五个主要谱系被认定为类群：Macrostyphlus类群（Rupanius、Adioristidius、Amathynetoides、Puranius、Macrostyphlus和Alndesianellus）、Antarctobius类群（Germainiellus、Antarctobius和Nacodius）、Listronotus类群（Haversiella、Listronotus和Neopachytychius）、Listroderes类群（Listroderes和Acrostomus）以及Falklandius类群（Falklandiellus、Falklandiopsis、Telurus、Falklandius和Lanteriella）。
