中国姬猎蝽新种记述(半翅目,姬猎蝽科)

姬猎蝽(Nabidae)是半翅目中的一个小科,从前人们把它作为猎蝽科的一个亚科;由于它们的喙显然是四节,以后又把它单独的列为一科。近年来的研究表明:本科的系统地位是在猎蝽总科和臭虫总科之间,并且更近于臭虫总科。 这科的种类多为捕食性,捕食各种较小的昆虫,所以是田间的一类益虫。 本科在我国已有记载的种类不多,胡经甫氏(1935)的中国昆虫名录中列举了8种,没有包括台湾的种类。在台湾共发现8种:Alloeorhynchus vinulus Stal(Reuter et Poppius,     

中国黄足猎蝽属厘订(半翅目:猎蝽科:盗猎蝽亚科)

本文记述黄足猎蝽属一新种——黑胸黄足猎蝽Sirthenea melanota sp.nov.,并与两个已知种——黄足猎蝽S.flavipes(Stal)及半黄足猎蝽S.dimidiata Horvath——进行了详细的比较。除黄足猎蝽外,其发音沟及雄性外生殖器构造均为首次记载。此外,指出S.clavata Miller可能是黄足猎蝽apicalis变型的同物异名。新种的鉴别特征是:黑色,光亮;头背面全为红黄褐色,前胸背板全为黑色;近似S.leonina Horvath,但其前翅色斑区别明显;体躯量度见表2;模式标本保存于西北农业大学昆虫博物馆。

EMBRYOGENY IN THE CALIFORNIA PEONIES WITH REFERENCE TO THEIR TAXONOMIC POSITION

Cave , Marion S. (U. California, Berkeley), Howard J. Arnott , and Stanton A. Cook . Embryogeny in the California peonies with reference to their taxonomic position. Amer. Jour. Bot. 48(5): 397–404. Illus. 1961.—The embryogeny of Paeonia californica Nutt. ex T. and G. and P. brownii Dougl. ex Hook. is described. No cell wall is formed at the end of the first division of the zygote nucleus, but instead, a massive coenocytic proembryo is produced. This structure becomes cellular, and numerous embryo primordia form on its surface, one of which gains ascendancy over the others to form the embryo proper, consisting of root, shoot apex, epicotylar leaf primordium, and 2 cotyledons. The embryogeny of the California peonies is essentially similar to that of P. anomala, P. moutan, and P. wittmanniana described by Yakovlev and Yoffe, and does not support the contention of Murgai that in P. albiflora, P. actiflora, P. delavayi, and P. suffruticosa the coenocyte is a suspensor. It is suggested that the coenocytic embryos of gymnosperms and Paeonia represent a case of parallel evolution rather than that there is any implication of phylogenetic relationships between them.     

MORPHOLOGY,EVOLUTION, AND TAXONOMIC SIGNIFICANCE OF THE INFLORESCENCE IN CORDYLANTHUS (SCROPHULARIACEAE)

The genus Cordyhmthus has considerable diversity in its inflorescences while the other genera of tribe Rhinantheae (Scrophulariaceae) uniformly have racemes or spikes. Four distinct inflorescence types are recognized and their homologies and evolutionary history are postulated. Thus it is suggested that the basic florescence type, the elongated spike (Type I), has undergone evolutionary reduction to a few-flowered spike and ultimately to a single-flowered florescence (Type II). Further evolution involving processes of compaction and clustering of the single-flowered florescences has resulted in glomerulate clusters (Type III) and spiciform clusters (Type IV). Knowledge of inflorescence homologies and distribution of the four inflorescence types in the genus has been of considerable aid in formulating a new infrageneric classification. Using evidence primarily from inflorescence, floral, and seed morphology, as well as from geographical distribution and ecology, a classification is proposed establishing three subgenera, namely subg. Dicranostegia, subg. Hemistegia, and subg. Cordylanthus, the last with three sections, sect. Cordylanthus, sect. Anisocheila, and sect. Ramosi.
