A taxonomic review of the genus Hypomicrogaster Ashmead is presented with the redescription and redelimitation of the already named species Hypomicrogaster ecus Nixon, H. imitator (Ashmead), H. tydeus Nixon and H. zonaria (Say). The review also implies eleven new synonymies, and a new combination for the species H. areolaris (Blanchard). Also, the present revision identified 40 new Hypomicrogas...

The genus Trigonopterus Fauvel, 1862 is highly diverse in Melanesia. Only one species, Trigonopterusamphoralis Marshall, 1925 was so far recorded West of Wallace's Line (Eastern Sumatra). Based on focused field-work the fauna from Sundaland (Sumatra, Java, Bali, Palawan) and the Lesser Sunda Islands (Lombok, Sumbawa, Flores) is here revised. We redescribe Trigonopterusamphoralis Marshall and de...

Field studies were conducted in a number of intertidal and offshore islands in the Persian Gulf between 2006 to 2013. SCUBA and skin diving surveys were conducted around Larak, Hormuz, Qeshm, Hengam, Farur, Kish, Lavan, Khark and Farsi islands in the northern region of the Persian Gulf. Marine invertebrates including nudibranchs were photographed up to 32 m. Several species of nudibranchs are r...

The aim of this study was to evaluate the effects of dilution rate and holding time on various motility parameters using computer-assisted sperm analysis (CASA). The semen samples were collected from three Ghezel rams. Samples were diluted in seminal plasma (SP), phosphate-buffered saline (PBS) containing 1% bovine serum albumin (BSA) and Bioexcell. The motility parameters that computed and rec...
