BACKGROUND The different features of scorpions can be successfully described by their nesting and burrowing behaviors. There is little information about burrowing activity of Iranian scorpions. METHODS The current study was performed to compare the burrowing behavior between two burrowing Iranian scorpions, Scorpio maurus and Odonthubutus bidentatus by describing 30 nests of each species rega...

The study of sexual reproductive behavior supported by ultrastructural evidence is important in rotifers to describe differences among potential cryptic species. In this research, the morphology of the rotifer Brachionus bidentatus is described at the ultrastructural level, using electronic microscopy, together with a brief description and discussion of its sexual reproductive behavior. The cha...

A new distichodontid fish from small streams on the fringes of the Upper Zambezi River floodplain, Zambia, is described. Individuals of the new species, Neolebias lozii n. sp., are small (maximum 18.0 mm SL) and distinguished from all other members of the genus by a series of tall, black vertical bars along the flanks, short caudal peduncle, and broadly rounded, caudal-fin lobes. Neolebias lozi...

A new genus Sundageophilus is here described for two new species of geophilid centipedes (Chilopoda: Geophilidae) from Sumatra, Indonesia. Both Sundageophilus bidentatus sp. n. and Sundageophilus poriger sp. n. feature a minute body size (less than 1 cm long with 31-35 pairs of legs), a similar structure of the maxillae, elongated forcipules, and few coxal organs. Sundageophilus bidentatus is u...

The leafhopper genus Nicolaus Lindberg is recorded from India and Pakistan for the first time. Four new species, N. abuensis sp. nov., N. bidentatus sp. nov., N. cornutus sp. nov. and N. serratus sp. nov. are described and illustrated. N. bihamatus Xing & Li, earlier known from China is recorded from India and Pakistan. A key to the species of Nicolaus from the study area is provided.
