Digital microscopic imaging of important taxonomic characters of Philippine Hydraena (Hydraenopsis) species

Biodiversity surveys have revealed several new aquatic beetle species of minute size (0.9 mm to 1.8 mm body length). Following modern standards of morphological taxonomy, internal and external microstructures such as aedeagus, ovipositor, spermatheca, gonocoxite as well as the distribution pattern a...
