A newly described marine diatom with exceptionally delicate, gossamer shells, discovered in Honolulu Harbor. This study introduces Achnanthes subhyalina, a tall, slender Pennate diatom whose shells are extremely delicate and often evade easy preparation. The description highlights its unique valve shapes, faintly visible markings, and the way it behaves under different preparation methods, making it a noteworthy addition for researchers of marine microalgae.

Based on careful observation, the species forms short- to linear-oblong frustules, sometimes appearing long-rectangular with rounded ends. It has a straight, narrow raphe and a central transapical area, with chromatophores described as brown and variable in appearance between young and older cells. The organism thrives in seawater from Honolulu Harbor, illustrating its adaptation to coastal marine environments. This edition emphasizes the practical challenges of studying such delicate shells, which require specialized approaches beyond conventional microscopy.

• Extremely delicate, gossamer-like shells that resist standard mounting methods


• Valve shapes described as short- to linear-oblong, with occasional long-rectangular forms


• Chromatophores that shift in appearance from young to older cells


• Habitat details centered on seawater from Honolulu Harbor, Hawaii

Ideal for students and professionals in phycology and taxonomy who seek precise, firsthand descriptions of new diatom species.
