Lateral horns on valves are found in few representatives from different families of the Anomopoda (Crustacea: Cladocera). We found that populations of "horned" Pleuroxus Baird, 1843 from mountains of Central Asia belong to two different species, P. pamirensis (Werestschagin, 1923) present in Pamirs, and P. annandalei (Daday, 1908), occuring in Tibetan Plateau, Baikal Rift System and Mongolian Altai. Redescriptions and a list of differences between the species are presented. Genera Cornuella Werestschagin, 1923 and Sinopleuroxus Chiang Sieh-chih, 1963 are suggested junior synonyms of Pleuroxus.

Abstract It has been suggested that summer rainfall over Central Asia (CA) is significantly correlated with the summer thermal distribution of the Tibetan Plateau (TP) and the Indian summer monsoon (ISM). However, relatively few studies have investigated their synergistic effects of different distribution. This study documents the significant correlations between precipitation in CA and the diabatic heating of TP and the ISM based on the results of statistical analysis and numerical simulation. Precipitation in CA is is dominated by two water vapor transport branches from the south which are related to the two primary modes of anomalous diabatic heating distribution related to the TP and ISM precipitation, that is, the “+-” dipole mode in the southeastern TP and the Indian subcontinent (IS), and the “+-+” tripole mode in the southeastern TP, the IS, and southern India. Both modes exhibit obvious mid-latitude Silk Road pattern (SRP) wave trains with cyclone anomalies over CA, but with different transient and stationary eddies over south Asia. The different locations of anomalous anticyclones over India govern two water vapor transport branches to CA, which are from the Arabian Sea and the Bay of Bengal. The water vapor flux climbs while being transported northward and can be transported to CA with the cooperation of cyclonic circulation. The convergent water vapor and ascending motion caused by cyclonic anomalies favor the precipitation in CA. Further analysis corroborates the negative South Indian Ocean Dipole (NSIOD) in February could affect the tripole mode distribution of TP heating and ISM via the atmospheric circulation, water vapor transport and an anomalous Hadley cell circulation. The results indicate a reliable prediction reference for precipitation in CA.

Collecting expeditions to China's Sichuan, Gansu and Qinghai provinces were conducted by the third author, along with Alessandro and Irene Floriani, during June 2009, April 2010 and July 2010. Light trapping yielded numerous noctuid moths including four new species, described herein. These new taxa reflect the high diversity of some genera (Hada, Billberg, 1820 ; Palaeamathes, Boursin, 1954) in SW China, and the biogeographical connections of the Tibetan Plateau to Central Asia (Lacanobia kitokia sp. n., L. contrastata (Bryk, 1942), L. mongolica Behounek, 1993, L. kirghisa Gyulai & Ronkay, 1998) and to the Himalayan Region (Palaeamathes serrulata sp. n. is close to P. harpegnoma (Hreblay & Ronkay, 1998).
