Diagnosis.
Dashymeniella spatulatiformis
can be recognized by the following set of features: dorsal surface varying from brown to dark brown, nearly black (
Figs. 13–14
); head somewhat rugose; endosoma with DSS spoonlike; PES stout, longer than other endosomal sclerites, gradually becoming narrower towards apex (
Fig. 96
).
D
.
spatulatiformis
is most similar to
D
.
ulu
and
D
.
viklundi
in sharing the following set of characters: dorsal surface glabrous (
Figs. 13–14, 16–17
); pronotum with the anterior margin separated from the remainder of the pronotum by relatively deep, transverse incision; posterior lobe of the pronotum without any swelling medially (
Figs. 13–14, 16–17
); pronotal calli flattened or weakly raised (
Figs. 13–14, 16–17
); DSS stout and large, occupying most of the endosoma, distinctly broadened apically; AES distinctly smaller than the DSS and not embracing the latter.
D
.
spatulatiformis
differs, however, by having the rugose frons, the pronotal calli weakly raised, and by the differing shape of the endosomal sclerites (
Figs. 96, 102, 105
); right paramere with the apical process narrower than remainder of the paramere (
Figs. 98, 104, 107
).
Description
.
Male
.
COLORATION
(
Figs. 13–14
). Dorsum varying from brown to dark brown.
Head
. Dark brown; vertex, maxillary and mandibular plates, and inner portion of gula somewhat paler than remainder of head; antennae dull yellowish; labium varying from dull yellowish with brown areas to reddish brown.
Thorax
.
Thoracic pleura
. Dark brown.
Legs
. Coxae brown; femora brown, dull yellowish apically; pro- and mesotibia brownish, with paler dull yellowish apex; metatibia brown, with pale yellow annulation apically; tarsi dull yellowish.
STRUCTURE AND VESTITURE
(
Figs. 13–14
,
52
,
94–95
). Suboval, dorsal surface strongly shining, glabrous.
Head
. Strongly shining, glabrous; vertex and frons with sparse, deep punctation; frons strongly rugose; antennal segment I covered with very sparse, fine setae, narrowed basally, apical half nearly cylindrical; segment II gradually thickened towards apex, with strongly shining basal portion, covered with moderately dense, long, semirecumbent setae; apex of labium reaching metacoxae.
Thorax
.
Pronotum
. Punctation moderately dense; calli weakly raised, inpunctate; anterior margin separated from remainder of pronotum by relatively deep, transverse incision.
Scutellum
. With moderately dense punctation and longitudinal, weakly raised elevation.
Hemelytron
. Covered with moderately dense punctation.
Legs
. Short; coxae, femora, and bases of tibiae covered with sparse setae; tibiae basally shining, apically matte, covered with dense, semirecumbent setae.
Male genitalia
.
Endosoma
(
Fig. 96
). DSS with broadened, rounded, spoon shaped apical portion; AES gradually becoming thinner towards apex; MES stout, large, hook-shaped; PES largest, stout, gradually becoming thinner toward apex.
Left paramere
(
Fig. 97
). Rounded; apical process somewhat sharply pointed apically.
Right paramere
(
Fig. 98
). Body nearly parallel-sided; apical process strongly narrower than remainder of paramere, sharpened apically.
Female
. Similar to male in coloration, structure, and vestiture but somewhat larger in size.

Etymology
. The specific epithet is derived from the Latin “spatula,” (spoon) and “forma,” (shape) and is used to denote the spoon shaped endosomal sclerite DSS.
