Freshwater aquatic insects in running creek. This insect was living in a tube with 5 prongs, connected by a web of mucus/silk which it used to catch particles in the water. I watch it actively eat the webbing and create new webbing. There were about 5 active ones on a rock, they were about 1cm tall.

Inside Halichondria sp. Looks like L. alata but extended process on article 5 on Gnathopod 2 is longer than average and dactyl has interior bump with setae. Gnathopod 1 dactyl minute with long setae, article 2 curves steeply. Coxae deeper than wider with numerous bumps. Stridulation ventral coxal plates. Rostrum more prominent with longer antenna. Antennae 1 with 16 segments and minute accessory flagellum. Eyes with >20 ommatidia

Female. Prominent accessory flagellum. Gnathopod 2 larger than G1, subchelate. Pleonite 3 posterior margin acute and overlay urosomite 1 and 2. Urosomite 1 having medial distal tooth and Urosomite 2 having 3 medial distal teeth with the one in the middle extending into the air. Telson laminar and deeply cleft with lateral and dorsal spines.

Inside of Halichondria sp. Two had a polka dot polka-dot pattern and some had a prominent ridge of the anterior side of the propodus, including the brooding female. Distinctly L. alata with antenna 1 with 9-13 segments and accessory flagellum.

Found in yellow Haplosclerid sponge on dock. Telson laminar and uncleft, uropod 3 with two Rami narrow and spiny. Gnathopod 2 larger than 1 with 1 being distinctly carpochelate and G2 being subchelate. G2 dactyl reach distal process of article 5. G1 dactyl shorter than article 3 Male has maxillapede instead of keel.

Species described as an invasive introduced to San Francisco bay.

2 individuals were collected. First thoracomere fused with head, 5th peronite (free, 6th thoracomere) compressed, peropods have 3 claw dactyl, pleotelson not pear shaped with medial small serrations, uropods half length of pleotelson, urosome flattish, narrow anteriorly, first pereopod propodus (article 6) smooth.
