Sympistis cherti
Troubridge
sp. n.
(Figs. E-18, N-4, S-8)
Diagnosis.
The transition between the dark terminal band the discal area is gradual on the dorsal hindwing of
S. cherti
, thus it might be confused with
S. homogena
.
It differs from
S. homogena
by the dorsal forewing, which is charcoal gray in
S. cherti
, without a ochre hue and without a lighter shade of gray between the outer margin and subterminal line.
Sympistis homogena
has a distinct ochre hue along the anterior margin of the antemedial line, a distinct pale area between the terminal and subterminal lines, and generally a lighter, more patterned forewing.
Description
. Antennae filiform, head charcoal gray; prothoracic collar a dark grayish brown; thorax and tegulae charcoal gray; abdomen light grayish brown. Coremata with brushes, levers, and pockets present on base of male abdomen. Forewing length
15-19 mm
.
Dorsal forewing
ground color charcoal gray; postmedial, antemedial and basal lines black; postmedial line edged distally by scattered lighter gray scales which blend to charcoal gray towards subterminal line; antemedial line narrowly bordered basally with light gray to grayish brown scales, subterminal line usually absent; terminal line black; orbicular and reniform spots outlined with black scales, filled with charcoal gray and dusted with white scales; fringe with light grayish brown basal line, a black medial line and dark gray terminal area.
Dorsal hindwing
basal area with white scales under long gray hairs and scattered gray scales giving a dirty, light gray appearance; veins with scattered gray scales; discal lunule gray; dark gray terminal shade blends gradually into discal area; fringe light grayish brown basally with white terminal line and black median line.
Male genitalia
. (Fig. N-4) Valve shaped like the prow of canoe, with distinct corona; ampulla of clasper gradually narrows to terminal spine arcing from posterior margin; clavus well-developed, about 1.5x as tall as wide. Vesica with small basal, ventral diverticulum bends slightly upward; a patch of short, sparse cornuti on left near base and second patch of much longer cornuti on right at base; a ribbon of long cornuti extends along ventral margin of apical ¾ of vesica; a second ribbon of longer, stouter cornuti extends on left side of apical ½ of vesica, nearly to apex, where vesica narrows and bends downward toward patch of long cornuti and single apical spine.
Female genitalia
. (Fig. S-8) Ovipositor lobes rounded, apex with long, fine setae, corona of short setae mid way down -these setae arc anteriorly; a ruff of longer, finer setae encircles ovipositor lobes at base; a Y-shaped sclerite occurs on ventral surface of ductus bursae at ostium bursae, ductus bursae about as long as corpus bursae, doubles in width at a point ca. ½ of the way from ostium bursae to appendix bursae; appendix bursae parallel sided, narrowing near anterior end towards ductus seminalis, meeting ductus bursae on right side near posterior end; corpus bursae ellipsoidal, about ¾ as large as appendix bursae, arises via narrow duct from left side of appendix bursae near ductus bursae, elongate signae on dorsal and ventral sides.
