贵州空棘鱼属的修订与系统发育分析

依据在云南富源中三叠世法郎组竹杆坡段发现的新材料,对关岭贵州空棘鱼(Guizhoucoelacanthus guanlingensis)进行了补充描述,并修订了鼻骨、顶骨、后顶骨、额外肩胛骨、眶后骨、偶鳍、鳞片等特征。系统发育分析表明,贵州空棘鱼属与Whiteia+Piveteauia构成姐妹群,其共有离征包括:两对顶骨的大小相近,第一背鳍鳍条数小于8。建议将贵州空棘鱼属归入怀特鱼科(Whiteiidae)。     

A SYSTEMATIC REVISION OF PHYLLANTHUS SUBSECTION URINARIA (EUPHORBIACEAE)

The examination of several taxa from various tropical regions of the world, previously classified as Phyllanthus urinaria L., indicates that they do not belong to a single species. On the basis of morphology, cytology, genetics, and biometry, a new classification is presented in which the collective species P. urinaria, or “urinaria complex,” is elevated to the subsection level: Phyllanthus subsection Urinaria. Within the subsection, two subgroups may be recognized on the basis of seed coat ornamentation. Each of these lines is represented by two species which differ from each other in chromosome number: P. embergeri nov. spec. (2n = 100) and P. nozeranii nov. spec. (2n = 50) in the “spiraled” line, P. hookeri Muell. Arg. (2n = 100) and P. urinaria L. (2n = 50) in the “radiated” line. In the latter species, which has undergone diversification, two subspecies may be distinguished: P. urinaria urinaria and P. urinaria nudicarpus subspec. nova.     

REVISION OF AUSTRALIAN HELONOTUS AMYOT AND SERVILLE (HETEROPTERA: REDUVIIDAE)

Abstract
Australian species of the genus Helonotus Amyot and Serville, viz. H. auricomus Miller and H. curvidens Miller, are synonymised with H. exsugiens Stål from New Guinea. H. exsugiens is redescribed with a lectotype and paralectotypes designated. Two new species, H. sextuberculatus sp. n. and H. queenslandensis sp. n. are described from northern Australia and a key to species is given.
