Description. Body brown with white spots on hemelytra, carinae and paranota, slightly shiny. Body length, 2.52; width, 1.12.

Head short, eyes small, armed with a median spine, a pair of frontal spines, a clypeal spine and a pair of jugal spines, all spines stout and straight, of the same length and directed forward; antennae long and slender, antennal joints measurements. I, 0.08; II, 0.06; III, 0.60; IV, 0.24; bucculae long and narrow, made of three rows of areolae, extended in front of clypeus, joined in front; rostrum reaching the first visible abdominal segment.

Pronotum short, swollen, punctuate, without posterior process, tricarinate; carinae laminate, with one row of areolae; median carina slightly larger than lateral ones, sinuate and continuous with a crest-like hood with two rows of areolae; collar four areolae wide; paranota laminate, sinuate, erected, with two rows of areolae all along; sulcus straight, sulcus laminae sub-parallel, with one row of areolae, metasternal laminae wider than mesosternal one, the areolae larger. Scent gland opening large, auricular. Apex of scutellum visible and restricted to a short white tubercle between the clavus; clavus developped with four rows of round aerolae.

Hemelytra large, progressively enlarged at base, divided in the usual areas; with areolae round and of the same size on all areas, except on posterior part of costal area where are larger; hypocostal area with one row of round areolae; costal area slighlty upraised, four areolae wide, subcostal area as wide as costal area, four areolae wide; R+M vein raised, discoidal area longer than hald the length of hemelytra, as wide as subcostal area, four areolae wide at widest part, subdivided in four parts by thin transversal veinelets; Cu vein thin and almost not distinct; sutural area narrow, six areolae wide at widest part.

Comment. The genus Distocader is known by only one single species, Distocader charieis (Drake and Ruhoff) which was described from a single specimen from New Guinea, which up to now was the only specimen known of the genus. The new species shares with D. charieis the lack of occipital spines. Although, the carinae, the paranota and the hemelytra of D. planti are larger and wider than on D. charieis . Also, the carinae of D. planti are sinuate, while the one of D. charieis are just slightly curved. In addition, the cephalic spines are much longer in D. planti .

Etymology. This species is named in honor to Adrian Plant who allowed the authors to study the fauna of the Tiger Project.
