Natural History Of The Spider Genus Lutica (Araneae, Zodariidae), Martina G. Ramirez Jan 1995

Natural History Of The Spider Genus Lutica (Araneae, Zodariidae), Martina G. Ramirez

Biology Faculty Works

Spiders of the genus Lutica are fossorial inhabitants of coastal dunes of southern California, Baja California and the California Channel Islands. They live in silk-lined burrows concentrated beneath dune vegetation. Lutica are sit-and-wait predators that subdue insects that walk near or over burrows . They are sedentary and do not engage in aerial dispersal via ballooning . Adult males abandon their burrows during the late summer and early fall to wander in search of females . Females produce eggsacs and guard them till they die; spiderlings emerge in the spring. Dune trapdoor spiders (Aptostichus simus) prey on Lutica, …

Phylogeny And Historical Biogeography Of The Spider Genus Lutica (Araneae, Zodariidae), Martina G. Ramirez Jan 1995

Phylogeny And Historical Biogeography Of The Spider Genus Lutica (Araneae, Zodariidae), Martina G. Ramirez

Biology Faculty Works

Spiders of the genus Lutica from 19 populations in southern California and Baja California, including all the California Channel Islands except Anacapa, were compared electrophoretically on the basis of variability at 15 gene loci. Fixed allelic differences clearly define two species: new species A [Santa Barbara and Ventura Counties, northern Channel Islands (San Miguel, Santa Rosa, Santa Cruz), southern Channel Islands (San Nicolas, Santa Barbara, Santa Catalina)] and new species C [Guerrero Negro, central Baja California], while morphological features define two others: new species B [Los Angeles, Orange and San Diego Counties, northern Baja California] and clementea [San Clemente Island] …
