 Pinodytes pusio Horn 1892: 45.   
 Catopocerus pusio: Hatch 1928: 72 (new combination).   
 Type material. Lectotype of P. pusio here designated, to ensure the name’s proper and consistent application, male, in MCZC, Horn collection; bearing white label “ Alameda Co. Cal ”; white label “1722”; pale green label “Para-Type 3028”; white hand-written label “ Catopocerus pusio Horn det S. Peck ‘68”; red label “MCZ TYPE 35341”; and our red lectotype label; seen. Type locality: Alameda County, California.   
 Additional material examined. We have examined an additional 267 specimens (see Appendix).   
 Distribution. Specimens (Fig. 87) are known from Alameda, Contra Costa, Fresno, Marin, Mariposa, Mendocino, Monterey, San Bernardino, San Francisco, San Mateo, Santa Clara, Santa Cruz, and Tulare counties, California.   
 Diagnosis. Total length 1.46–1.70 mm; greatest width 0.68–0.82 mm. Reddish brown; elongate oval in shape (Fig. 6). Head. Finely punctate, punctures separated by 2–4 diameters, with substriate microsculpture. Eyes absent. Antennae (Fig. 79) with antennomeres 2 and 3 subequal in length; antennomere 5 slightly larger than 4 and 6; antennomere 7 longer but not wider than 8; antennomeres 9 and 10 each with a sensory vesicle indicated apically by a protruding flange. Pronotum. Punctation similar to head, shining, with transverse substriate microsculpture. Widest near base; sides slightly rounded, narrowing to apex; apical margin emarginate, basal margin straight; apical angles rounded, basal angles rectangular. Elytra. Punctation moderately strong and dense mediobasally, finer apically and laterally; in longitudinal rows, some rows weakly impressed basally; an impressed lateral stria with larger closely spaced punctures; punctures joined transversely by fine strioles. Joined elytra slightly wider than pronotum, widest in basal one-third, narrowing to apex. Legs. Protibia (Fig. 80) moderately slender; spinose on apical one-half of outer margin and apically; fine dense spines on apical one-half of inner margin. Mesotibia (Fig. 81) moderately slender; strongly spinose on outer margin and apically; fine spines on inner margin. Metatibia (Fig. 82) slender, straight; outer margin weakly spinose, inner margin with fine spines. Metafemur (Fig. 82) broad in larger males, more slender in smaller males and females. Male protarsomeres (Fig. 80) expanded, bearing elongate setae laterally and thin, colorless transverse phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite (Fig. 86) carinate, longitudinal carina with tooth near middle; not excavated behind transverse carina. Male genitalia. Median lobe of aedeagus (Figs. 83, 84) elongate, broad, narrowing to rounded apex; with lateral notches before apex; apex flattened only at extreme tip. Inverted internal sac (Fig. 84) with small complex sclerotized structure. Parameres (Figs. 83, 84) elongate, broad, with flattened apices; each bearing two setae before apex; parameres extend beyond apex of median lobe. Spermatheca. Tubular (Fig. 85), coiled before duct.
