The new species have a long stylet in the male reproductive system, which is different from that of the known species of the genus. Specimens of Syndesmis selknami n. sp. have a ∼220-μm-long stylet (∼1/3 of the body length, 0.69 mm). This ratio is unique because only four...

rubida sp. nov., which have strong antibacterial activity against Gram-positive bacteria1\ The complex consists of seven components; mycinamicins I (1), II (2), III (3), IV (4), V (5), VI (6) and VII (7)2~4). During the search for new antibiotics from the fermentation broth of mycinamicinproducing strains, we have discovered a new minor component designated mycinamicin VIII (8). Recently, the s...
