Description of a New Subspecies of the Genus Saurogobio Bleeker (1870)

The genus Saurogobio Bleeker (1870) is a group of small sized cyprinids. Saurogobio dabryi Bleeker (1871) is widely distributed in East Asia.On the basis of careful inspection of morphological and meristic characters of specimen collected from Chenghai Lake in Yunnan and the opening river systems including Pearl River,Minjiang River,Yangtze River,Liaohe River and Songhuajiang River,the Chenghai Lake population of Saurogobio dabryi is considered to represent a new subspecies, Saurogobio dabryi chenghaiensis . Saurogobio dabryi chenghaiensis is distinguished by the combination of following characters.Rostral cap developed,covering over upper lip,and lips with developed papillae.Body and caudal peduncle very slender,body depth 12 7%-15 0% of standard length(SL),caudal peduncle depth 5 5%-6 1% of SL and 31 8%-39 1% of caudal peduncle length.A longitudinal dark stripe present along the axis on each side of body and 6-11 stick shaped black spots (its widths being 25%-50% of its lengths respectively) occur along the stripe.Distance from pelvic fin origin to anus is more than 50% of pelvic fin length.The length of the shortest caudal fin ray is less than 50% that of the longest one.The new subspecies occurs only in Chenghai Lake,Yunnan,China.

Taxonomy of the genus Uloma Dejean(Coleoptera:Tenebrionidae:Tenebrioninae) from Thailand

The paper deals with Thai species of the genus Uloma Dejean.

A key and photos of the known species of Uloma from Thailand are presented. A redescription of the male and the first description of the female of Uloma rufilabris Fairmaire, 1882 are also provided.

A Study of the Genus Podagricomela Heikertinger (Coleoptera:Chrysomelidae:Alticinae) from China

Ten species of Podagricomela Heikertinger from China are studied. They are Podagricomela apicipennis (Jacoby), P. cupera Wang, P. cyanea Chen, P. flavitibialis Wang, P. geminata Chen et Zia, P. nigricollis Chen, P. nigripes Medvedev, P. parva Chen et Zia, P. shirahatai (Ch?j?), and P. weisei Heikertinger. Among them, P. nigripes Medvedev is recorded for the first time from China. A key to species from China is given. Illustrations of the male aedeagus and female spermatheca of each species are also given. The geographical distribution in China is analyzed briefly. The result indicates that Podagricomela mainly occurs in southern China, southwestern China, central China and north China, and the distribution center of this genus is in China. They always feed on Rutaceae.

The cicada genus Pomponia St?l,1866(Hemiptera:Cicadidae) from China
