September 1997 Specimens representing 19 orders and 169 arthropod families (mostly insects) were collected from greenleaf manzanita brushfields in northeastern California and identified to species whenever possible. More than500 taxa below the family level wereinventoried, and each listing includes relative frequency of encounter, life stages collected, and dominant role in the greenleaf manzanita community. Specific host relationships are included for some predators and parasitoids. Herbivores, predators, and parasitoids comprised the majority (80 percent) of identified insects and related taxa.

[email protected]; https://orcid.org/0000-0003-2687-6740 Abstract In the subfamily Erotylinae (Coleoptera: Erotylidae), several nomenclatural concerns in the Australian fauna are corrected for upcoming publications. Spelling and attribution of the genus “Aulacochilus” is discussed and is correctly cited as Aulacocheilus Dejean, 1836. The species Episcaphula tetrastica Lea, 1921, becomes Aulacocheilus leai (Mader, 1934), new combination. Through a previous synonymy of Tritoma australiae Lea, 1922 with Hedista tricolor Weise, 1927, and the subsequent transfer of T. australiae into Spondotriplax Crotch, 1876, the genus Hedista Weise, 1927 is recognized as a synonym of Spondotriplax Crotch, 1876, new synonymy.
