Pugettia
kelp crabs
Pugettia is a genus of marine kelp crabs in the family Epialtidae, distributed across the North Pacific from North America to East Asia. Species inhabit shallow subtidal zones, primarily associated with macroalgal habitats including kelp beds, Sargassum stands, and red algal turfs. Many species exhibit ontogenetic habitat shifts, with juveniles and smaller individuals occupying deeper algal turfs while larger adults migrate to shallower macroalgal beds. The genus includes approximately 25 extant species plus one fossil species, with several species serving as important subjects for studies of crab growth, reproduction, and habitat ecology.

Tetramesa
Tetramesa is a genus of minute phytophagous wasps in the family Eurytomidae comprising over 200 described species. Members are exclusively associated with grasses (Poaceae), where they typically induce stem or inflorescence galls. The genus exhibits pronounced host specificity, with most species restricted to a single grass species or closely related congeners. Several species have been deployed as biological control agents against invasive grasses, including T. romana for giant reed (Arundo donax) and candidate agents for medusahead (Taeniatherum caput-medusae) and African lovegrass (Eragrostis curvula). Adults feed on nectar. Recent phylogenomic studies have synonymized the genera Aiolomorphus and Cathilaria within Tetramesa.
