Sympistis lachrymosa
Troubridge
sp. n.
(Figs. B-15, K-8, P-8)
Diagnosis.
The only species with which
S. lachrymosa
could be confused is
Sympistis simplex
(Smith)
comb. n.
(Fig. B-14). Both species have a brown forewing, dark hindwing terminal shade, and teardrop shaped orbicular spots. In
S. simplex
, the hindwing terminal shade reaches the anal angle but falls short in
S. lachrymosa
males. In
S. lachrymosa
, the forewing has a black dash that extends from the reniform spot to the subterminal line and a second black dash that extends from the claviform spot to the base of the forewing, both of which are absent in
S. simplex
.
Description
. Antennae filiform; head, vertex, thorax, and abdomen brown. Prothoracic collar tan with subterminal and subbasal black lines. Tegulae tan with subterminal black line. Forewing length
17-18 mm
.
Dorsal forewing
ground color tan to grayish brown; black undulating antemedial line and postmedial lines thinly bordered with off-white scales; off-white subterminal line irregular, bordered basally with narrow black chevrons between veins -chevrons tipped distally with off-white scales; terminal line consists of a series of small black chevrons between veins; orbicular, reniform, and claviform spots well demarcated with thin black outer and off-white inner lines; black basal dash reaches claviform spot; fringe brown, with off-white at tips of veins.
Dorsal hindwing
white with minute black discal dot; dark grayish brown terminal shade complete and sharply defined in females, narrower and incomplete in males, extending from veins Sc+R1 to CuA2; fringe grayish brown basally, white distally.
Male genitalia
. (Fig. K-8) Valve resembles prow of canoe, widest just beyond clasper, then gently tapered to cucullus; ampulla of clasper extends dorsally at right angles to ventral margin of valve, tapers evenly to apex near dorsal margin of valve. Vesica sweeps 90° ventrally with a small basal diverticulum; a ribbon of cornuti extends from dorsal surface at diverticulum along posterior surface to tip, and then back on the left side toward base; a second ribbon of long, dense cornuti located on right side of vesica; single apical cornutus and small bundle at apex.
Female genitalia
. (Fig. P-8) Ovipositor lobes rounded with scattered setae; a corona of short setae surrounds the ovipositor lobes about
0.1 mm
from tip, these setae are produced at 90° to the abdomen; a sclerite occurs on ventral surface of ductus bursae at ostium bursae, ductus bursae otherwise not heavily sclerotized; appendix bursae 2x as long as wide, with ductus seminalis at anterior end; corpus bursae with two elongate signae extends from left of appendix bursae and is slightly larger than appendix bursae.
