Distribution.
Specimens (
Fig. 87
) are known only from the San Gabriel Mountains, Los Angeles County,
California
.
Diagnostic description.
Total length
1.34–1.54 mm
; greatest width
0.66–0.74 mm
. Dark reddish brown; elongate-oval in shape (
Fig. 9
).
Head
. Finely, sparsely punctate; shining; transverse substriate microsculpture on vertex and laterally. Eyes absent. Antenna (
Fig. 104
) with antennomere 2 slightly longer than 3; antennomere 5 wider than 4 and 6; antennomeres 7 and 8 subequal; antennomeres 9 and 10 each with a single sensory vesicle indicated apically by a protruding flange.
Pronotum
. With fine punctures separated by 2–3 diameters; shining; with substriate microsculpture. Widest before base, sides curving to apex; apical margin weakly emarginate, basal margin nearly straight; apical angles obtuse, basal angles weakly obtuse, narrowly rounded.
Elytra
. Basally, punctures larger than on pronotum; longitudinal rows discernable basally; shining; punctures joined by fine transverse strioles. Slightly wider than pronotum, widest in basal one-third, roundly narrowing to apex.
Legs
. Protibia (
Fig. 105
) moderately widened apically; spinose on outer margin and apically; dense setae on apical two-thirds of inner margin. Mesotibia (
Fig. 106
) moderately broad apically; strongly spinose on outer margin and apically; smaller spines on apical one-half of inner margin. Metatibia (
Fig. 107
) elongate, slender, slightly curved; strongly spinose apically; a single strong spine near middle of outer margin. Metafemur (
Fig. 107
) slender. Male protarsomeres 1–4 expanded, bearing elongate setae laterally and thin, broad, colorless phanerae ventrally (
Fig. 105
). Mesotarsomeres without phanerae.
Venter
. Mesoventrite (
Fig. 111
) carinate; longitudinal carina with tooth-like expansion near middle; not excavated behind transverse carina.
Male genitalia
. Median lobe of aedeagus (
Figs. 108, 109
) elongate, broad, sharply constricted before flattened apex. Inverted internal sac (
Fig. 109
) with two elongate sclerites. Parameres (
Figs. 108, 109
) elongate, extending beyond apex of median lobe; with flattened apices; each bearing two setae before apex.
Spermatheca
. Tubular (
Fig. 110
), slender, curved.
Etymology.
The name
constrictus
, Latin
, contracted, refers to the shape of aedeagal apex of this species.
