Additional material examined.
We examined
934 specimens
additional to those listed above (See Appendix) for a total of 1031 specimens.
Distribution.
Specimens (
Fig. 136
) are known only from Del Norte and Humboldt counties in northwestern Califonria.
Diagnostic description
.
Total length
1.32–1.46 mm
; greatest width
0.82–0.86 mm
. Reddish brown; oval in shape (
Fig. 14
).
Head
. Finely, sparsely punctate, shining, with faint reticulate microsculpture on vertex. Eyes absent. Antenna (
Fig. 145
) with antennomeres 2 and 3 subequal in length; antennomere 5 wider than 4, subequal to 6; antennomere 7 longer but not wider than 8; antennomeres 9 and 10 each with a single sensory vesicle indicated apically by a protruding flange.
Pronotum
. Minutely, sparsely punctate; with reticulate microsculpture. Widest at base, nearly as wide as elytra; sides rounded, narrowing to apex; apical margin weakly emarginate, basal margin nearly straight; apical angles broadly rounded, basal angles narrowly rounded.
Elytra
. Finely punctate; punctures in obscure longitudinal rows; with fine, widely spaced transverse strioles. Joined elytra slightly wider than pronotum, widest at basal one-fourth, narrowing to apex.
Legs
. Protibia (
Fig. 146
) slender; apical two-thirds of outer margin and apical margin spinose; apical three-fifths of inner margin with fine spines. Mesotibia (
Fig. 147
) slender, straight; strongly spinose apically; a large, elongate spine at middle of outer margin. Metatibia (
Fig. 148
) slender, nearly straight; strong spines apically; smaller spines on apical three-fifths. Metafemur (
Fig. 148
) slender. Male protarsomeres (
Fig. 146
) feebly or not dilated, bearing elongate setae laterally and thin, broad, colorless phanerae ventrally. Mesotarsomeres without phanerae.
Venter
. Mesoventrite (
Fig. 152
) carinate; longitudinal carina with a toothlike expansion near middle; transverse carina on different plane than longitudinal carina; not excavated behind transverse carina.
Male genitalia
. Median lobe of aedeagus (
Figs. 149, 150
) broad with flat, dorsally depressed, rounded apex. Inverted internal sac (
Fig. 150
) with two pairs of elongate, narrow structures near middle; posteriorly with a distinctive elongate, dark structure bearing spines. Parameres (
Figs. 149, 150
) moderately narrow, extending to near apex of median lobe; with flat, deflexed apices, each bearing two closely spaced setae before apex.
Spermatheca
. Elongate (
Fig. 151
), tubular, sinuate.
Etymology.
The name
humboldtensis
refers to the abundance of this species in Humboldt Co.,
California
