Diagnosis.
As for the genus (see above).
Description.
Male, length 9.9 mm, width 9.9 mm; female, length 11.0 mm, width 10.0 mm. Coloration mainly black; anterolateral and posterolateral
Fig. 13.
Consensus tree of 24 most parsimonious trees (Length = 150, CI = 0.42, RI = 0.69). Black circles indicate nonhomoplasious characters; white circles indicate homoplasies; character numbers are above black or white circles, character states are below the circles; taxa in boxes represent the flightless lineages. Only unambiguous characters are mapped.

margins of pronotum orange to red; sub-basal, middle, and subapical regions of elytral explanate margins orange; sub-basal, postmedian, and subapical areas of disc also orange to red; legs (

) black with pale brown setae; abdomen (
Figs. 3, 6
) black with sublateral brown depressions on ventrites II–V.
Antennomere (
Fig. 14
) IV slender, slightly broader apically; antennomere V about 0.8 times as long as antennomere IV, broader apically; antennomeres VI–VIII each as long as antennomere V, broader than antennomere V; antennomeres IX–X quadrate, as long as antennomere V; antennomere XI slightly shorter than antennomere III. Pronotum (
Figs. 1, 4
) hemispherical with disc and anterior margin slightly convex; lateral margin rounded, smoothly curved without angle at posterolateral margin; explanate margin broader posteriorly; basal line broadly rounded; disc distinctly delimited by black coloration and depression between disc and margin; discal surface smooth; lateral marginal area finely and sparsely punctate; ventral surface of anterior margin rugose (
Fig. 23
). Prosternum (
Figs. 3, 6
,
20
) with surface irregularly wrinkled; prosternal process slightly swollen, with carved mark on surface. Tarsomere I (
Figs. 1, 6
) hemispherical; tarsomere II heart-shaped, 2 times as long as tarsomere I; tarsomere III bilobed, as long as broad, 2.5 times as long as tarsomere I; tarsomere IV as long as tarsomere III, 2.5 times as long as tarsomere I.

Etymology.
The specific epithet is a patronym honoring Mr. Edward G. Riley, entomology collection manager at
Texas
A&M University and specialist on the
Chrysomelidae
. He was the first to notice the distinctiveness of the unusual specimen, designated herein as
holotype
, from the TAMU collection.
