Graphosoma lineatum
  • Cimex lineatus Linnaeus, 1758


G. lineatum can reach a length of 8–12 mm (0.31–0.47 in). The body is almost round, with a large shield. The basic color of the upperside of the body is orange yellow, with wide black longitudinal stripes. The pronotum has six black bands. The antennae are black. Also the sides of the abdominal segments (connexivum) are yellow with many small black spots. The legs are mostly orange, which distinguishes it from its relative, G. italicum.


Graphosoma italicum had been regarded as either a subspecies, or a synonym of G. lineatum, but the validity of G. italicum was reestablished via DNA analysis, which demonstrated that the sister species to G. italicum is G. rubrolineatum, while G. lineatum is more closely related to G. semipunctatum.[1][2][3]


  • G. l. lineatum (Linnaeus, 1758) - nominate subspecies
  • G. l. siciliensis Lupoli, 2017[3] - endemic to Sicily. Black legged, more reddish coloured; only occurrence of the species in Europe, it actually looks close to its European relative, G. italicum.

G. lineatum is distributed across Northern Africa (Morocco, Algeria, Tunisia). The subspecies G. l. siciliensis occurs only in Sicily.
