Diagnosis.
Dashymenia tenmalai
is recognized by the following set of features: antennal segment I nearly cylindrical, entirely dark red to dark brown; pronotal pale, lateral stripes narrow, hardly visible in dorsal view (
Figs. 10–11
); segment II somewhat flattened laterally (
Fig. 10
); scutellum orange with a large, medial dark brown tinge originating from basal margin (
Figs. 10–11
); DSS strongly broadened basally, remainder of the segment gradually becomes narrower and forming a sharply pointed apex (
Fig. 80
).

in sharing pale lateral stripes on the pronotum. This species can, however, be distinguished by the coloration of the antennal segment I and the shape male genitalia.
Description
.
Male
.
COLORATION
(
Figs. 10–11
). Dorsum mostly dark brown with orange areas.
Head
. Dull yellowish, sometimes tinged with brown or red; antenna blackish dark brown; antennal segment I usually dark red, rarely dark brown; segment II varying from dark brown to blackish; segments III and IV dark brown; labium brown.
Thorax
.
Pronotum
. Dark brown, tinged with yellow or orange anteriorly and laterally.
Scutellum
. Orange, with distinct dark brown patch originating from basal margin, occupying most of medial portion of dorsal surface, not reaching apex.
Thoracic pleura
. Proepimeron varying from dull yellow to orange; remaining pleura dark brown; evaporative areas fuscous; peritreme brown.
Hemelytron
. Dark brown; clavus with yellowish or orange stripe along its inner margin (claval commissure yellowish to orange); corium with a medially situated and relatively broad orange patch in apical portion, contiguous with inner angle of cuneus; membrane fuscous to dark fuscous.
Legs
. Dark reddish brown, except for dull yellowish tarsi.
Abdomen
. Brown with dark brown areas.
STRUCTURE AND VESTITURE
(
Figures 10–11
,
66–79
). Elongate oval; dorsal surface mixed with dense semirecumbent and erect setae.
Head
. Covered with relatively long, protruding setae; vertex and frons weakly rugose; vertex with two, somewhat convex tubercles, each contiguous with occipital carina and inner margin of each eye; antennal segment I covered with moderately dense, long, semirecumbent setae, segment nearly cylindrical, weakly narrowed basally; segment II weakly bicompressed, mixed with three
types
of setae: dense, long, semirecumbent setae (similar to those present on segment I but denser), fine, short, scale-like, sparse setae, and several protruding, bristlelike setae; segments III and IV shining, covered with moderately dense, semirecumbent, bristlelike setae; labium stout, apex reaching procoxae apically.
Thorax
.
Scutellum
. Scutellum somewhat convex.
Thoracic pleura
. Proepimeron deeply and coarsely punctate; mesepimeron with punctation occupying its dorsoposterior surface, remainder of mesepisternum smooth and heavily polished; metepisternum inpunctate.
Hemelytron
. Membrane with minor cell hardly visible; major cell rather small, rounded.
Legs
. Covered with moderately dense, almost recumbent setae; tarsomere II divided; pretarsal claw not toothed subapically.
Abdomen
. Weakly narrowed toward apex, covered with moderately dense setae.

Right paramere
(
