Diagnosis.
This species differs from all known species of
Terraplistes
by: maxillary palps with apical, subapical and third segments completely black; first (basal) and second segments mostly black but distally white; male paraproct process with dorso-apical angle obtuse and ventro-apical angle more acute, very setose along apical margin.
Description (n = 5).
Habitus as typical for the genus (
Fig. 8
A). Frontal rostrum about 3.3 times broader than scapus. Maxillary palps with apical (fifth) segment elongated, moderately widened and apex strongly oblique; fourth segment with apical part slightly widened, third segment cylindrical; apical segment longer than third and fourth segments (
Fig. 8
B). Pronotum in male about 1.3 times longer than wide; with anterior dorsal margin concave, lateral margins slightly narrowed anteriorly, and posterior dorsal margin broadly rounded, covering tegmen completely.
Hind
femur about 1.6 times longer than hind tibia; hind tibia 1.5 times longer than hind metatarsus.
Male. Last abdominal tergite and epiproct partly fused to a supra-anal plate; triangular, transverse at base and obtuse at apex; with a row of setae along margin (
Fig. 8
D). Cercus stout and fairly long. Subgenital plate broadly rounded. Paraproct process with club-like projection, separated from base by wide but shallow gap; projection fairly large, with dorso-apical angle obtuse and ventro-apical angle more acute, very setose along apical margin (
Fig. 8
E). Sclerotized structure in phallic complex absent.
Female. Supra-anal plate setose, apical margin rounded. Subgenital plate triangular, about as long as wide, apical margin concave (
Fig. 8
F). Ovipositor short, with apical valves narrow; dorsal valve slightly longer than ventral valve; dorsal valve and ventral valve with apex acute, (
Fig. 8
G).
Colouration. Generally black. Head black, eye brown; scapus and basal antennal segments black, antenna pale with black rings. Maxillary palps with apical, subapical and third segments completely black; first (basal) and second segments mostly black but distally white (
Fig. 8
B). Pronotum black (
Fig. 8
C). Mesosternum and metasternum black. Wing white (
Fig. 8
C). Legs, including tarsus, generally black.
Hind
femur with inner surface black; outer surface black with some brown scales.
Hind
tibia black. Abdominal tergites mostly black with scales along distal margins of tergites brown; abdominal sternites and subgenital plate black in male and dark brown in female. Cercus brown, more pale basally and darker apically (
Fig. 8
D). Ovipositor brown (
Fig. 8
G).

Etymology.
This species is named after Sigfrid Ingrisch, who has made immense contribution to the taxonomy of
Mogoplistinae
from Southeast Asia, including the erection of the genus
Terraplistes
.
