Peyrierocoris , new genus

Type species of genus: Peyrierocoris mirabilis n. sp.

Description: Macropterous female:

Colouration: Basic colouration orange to red with dark markings on head, legs, hemelytra, abdomen, and connexiva.

Structure: Body small, slightly elongated. Entire body shiny. Setae on body pale and various-sized, mostly long and erected ( Figs 1 , 2 ). Females slightly larger than males with subquadrangular abdomen and distinctly longer and slender cells on membrane.

Head small, with slightly elongated anteocular part and long neck. Clypeus distinctly convex and directed downwards. Eyes large, not reaching margins of the head in lateral view. Posterior margin of the eyes reaching anterior margin of ocelli in lateral view. Ocelli medium-sized on distinct tubercles. Vertex convex with short, longitudinal, depressed line connected with transversal suture of the head. Antennifers very short, with apices directed laterally. Dorsal surface of antennifers partially fused with frons but distinctly visible. Head with medium-sized setae. All antennal segments thin. Second labial segment longest, fusiform.

Pronotum about 1.15 times wider than long. Anterior pronotal lobe distinctly divided on two lateral lobes and with distinct longitudinal groove in the middle. Lateral lobes of anterior pronotal lobe egg-shaped in lateral and dorsal view. Collar of anterior pronotal lobe very thin with very distinct, rounded calli. Margins of anterior pronotal lobe with short and medium-sized setae. Posterior pronotal lobe with very distinct depression in the middle. Lateral parts of posterior margin of posterior pronotal lobe flattened and curvate. Posterior margin of posterior pronotal lobe elongated in 1/3 of width on each side to distinct processes with rounded apices. Margins of posterior pronotal lobe with medium-sized and long setae.

Scutellum triangular with rounded apex and distinct robust Y-shape calli (very robust in apical part). Lateral margins very slightly curved in dorsal view. Median depression crescent and deep.

Hemelytra with transparent clavus, anal cell and hemelytra transparent, shiny with distinctly sculptured membrane. Costal margin slightly arcuate on the height of scutellum ( Fig. 1 ). Apical internal cell distinctly extended in basal part by S-shaped basal part of Cu1 vein in place of connection with Cu2. Apical external cell distinctly restricted in basal part by U-shaped curvature on medial vein. Corium transparent except basal part. Setae on hemelytrae placed on veins very dense in basal part of costal vein.

Thorax with medium-sized setae. Prosterna short, stridulatory organ surrounded by dense, short setae. Mesosterna with U-shaped depression (with triangular apex) in anterior part (apical part of depression placed between coxae). Lateral parts of mesothorax rounded in ventral view. Metasterna convex with slight depression in the middle and connected with mesosterna by distinct ridge.

Legs slightly curved with long and regularly arranged hairs. Femora gradually narrower into the apex. Apical part of ventral side of each femora with distinctly visible small bump; apex of each femora distinctly thinner. Apex of fore tibiae with distinct, sharp process on ventral side; process with sharp apex. Third tarsomere longest (slightly longer than first and second together).

Abdomen subquadrangular, distinctly wider than pronotum. Connexivum large, directed upward and fully exposed in dorsal view with slightly rounded external margin. Ventral part of abdomen distinctly convex with slightly flattened medial part. Pygophore large.

Macropterous Males: All characters of males are similar except robust body, and quadrangular abdomen. Cells on membrane more slender in males.

Differential diagnosis: The genus Peyrierocoris can be recognized from other genera of Harpactorinae in Madagascar by small body, head with short postocular region, slightly elongated anteocular part of the head with distinctly downward clypeus, oviform lateral lobes of anterior pronotal lobe, and distinct sharp processes on posterior margin of pronotum. Body slender and distinctly shiny with subquadrangular abdomen. Head with medium-sized eyes, not reaching margins of head in lateral view, and short antennifers.

Etymology: Name of the genus is dedicated to A. Peyrieras, one of the collectors of specimens belonging to this new genus.

Distribution: Madagascar ( Fig. 35 )
