蛛缘蝽科系统发育初探(半翅目:缘蝽总科)

本文通对蛛缘蝽科各亚群16个代表属的比较形态学研究,以支序分析方法探讨了属间系统发育关系,其结果证实蛛缘蝽科为一单源群,支持Schaefe(1965)将该科分为蛛缘蝽亚科和微缘蝽亚科的意见,并认为扁缘蝽属和锥缘蝽属应分别单独成立族。Ahmad(1965)等将原有蛛缘蝽族、稻缘蝽族和微翅缘蝽族分别提升为亚科从而将该科分为三亚科的观点得不到文中支序图的支持。

PRELIMINARY STUDY ON THE PHYLOGENY OF ALYDIDAE (HEMIPTERA:COREOIDEA)

To date, very little research work has been done on the phylogeny of the Alydidae. Thepresent paper presents the results of a comparative morphological study of 16 representativegenera of this family and attempts to interpret the phylogenetic relationships among generafrom a cladistic approach. Results show that the Alydidae is a monphyletic group, that thegenera Daclera and Acestra should be separately erected as tribes, and that Schaefer's (1965)division of this family into two subfamilies--Alydidae and Micrelytrinae is reasonable. Ourcladograms do not support Ahmad's (1965) and some other authors' contention that the Aly-didae be divided into three subfamilies-Alydidae, Leptocorisinae, and Micrelytrinae. The nu-merous data on the comparative morphology, figures, adn phylogenetic schemes of this familyprovided in this paper would serve as useful information for further studies on this topic.
