Planeocoris , new genus

Type species of the genus: Planeocoris redeii n. sp.

Diagnosis: The genus can be easily recognized by the extremely flat ( Fig. 16 ), dull body and pale coloration. Body medium-sized and robust with distinctly visible spines on the ventral surface of the fore femora and with dense, long setae placed on the granulations of the dorsal surface of the fore femora. The head cylindrical and elongated with relatively small eyes and with four processes on the apical part of the head (two on the clypeus and two on dorso-lateral part of the head). The head has distinct granulations especially on the postocular part. The first antennal segment is the thickest, and slightly curved. The pronotum is gradually expanded onto its basal part with very distinct longitudinal depression, wider on the posterior pronotal lobe. There are distinct, large granulations on the pronotum. The posterior lobe of the pronotum has slightly elongated angles. The middle and hind legs have dense setae. Abdomen is gradually expanded distally.

Description: Macropterous male: body medium-sized, elongated, flat with ovoid abdomen. Entire body dull, pale brown and yellowish with erected, pale setae ( Fig. 1). Head elongated, cylindrical, distinctly shorter than pronotum. Eyes and ocelli medium-sized. Eyes pigmented, not reaching dorsal and ventral line of the head in lateral view. Abdomen wide. Ocelli not pigmented. Anteocular part of the head 1.5 times longer than postocular part with visible spines on clypeus and dorso-lateral part of antennifers. First antennal segment thickest, slightly curved, and distinctly surpassing apex of head by half of its length, third segment very thin. Second antennal segment longest. Collar processes distinctly developed, robust. Anterior and posterior pronotal lobes longitudinally depressed, depression on posterior pronotal lobe wide. Posterior pronotal lobe wider and shorter than anterior lobe. Apical margin of anterior pronotal lobe strongly indented, indentation rounded. Lateral pronotal angles slightly elongated with rounded apices. Scutellum with short, rounded apex. Fore trochanters and femora with one line of long spines and small number of setae on ventral surface; four lines of small spines and numerous setae visible on dorsal surface. Other parts of fore, middle, and hind tibiae unarmed. Fore tibiae distinctly curved. Hemelytra dull with distinctly sculptured membrane. Setae on hemelytra placed on veins. Abdomen gradually expanded distally. Connexiva with expanded and elongated posterior part.

Distribution: Madagascar

Etymology: The name of the genus is connected with its very flat body in lateral view as well as its pale colour.
