Taxonomic position

Hemiptera: Heteroptera: Pentatomidae: Pentatominae

Diagnosis
  • Apex of head nearly rounded and reflexed upwards
  • Mandibular plates meeting in front of clypeus
  • Pronotum with anterolateral margins straight, not reflexed, smooth
  • External scent efferent system with peritreme reduced
  • Legs with femora unarmed, tibiae dorsally with distinct, broad, longitudinal groove, tibiae not dilated
  • Basal abdominal sternites smooth, without spine or tubercle
Male genitalia

Genital capsule quadrangular; ventral rim deeply excavated concave, with median conical projection; two stout finger-like projection submedially inner to median conical projection; caudal lobes indistinct with apex angulate; dorsal rim widely and deeply excavated concave between caudal lobes. Paramere crown finger-like gradually tapering towards apex; phallus with phallotheca short, pear-like, less sclerotized.

Female genitalia

Valvifers VIII developed into large, longitudinal, triangular plates; valvifers IX reduced into short quadrate and transverse plate; laterotergite IX short and triangular not reaching apex of abdomen; laterotergite VIII transverse, short, elongate and triangular with smooth caudal margin. Spermatheca with spermathecal dilation; apical receptacle elongate and conical.

Biology

Female lay about 100-200 eggs singly or in small clusters of 2–13 eggs on aerial plant parts.  Newly deposited eggs are dirty white with reticulated surface, later change to orange-red. Incubation period of 2–6 days, nymphal duration 17-33 days and adult longevity 8 to 26 days (Palumbo et al., 2016).

Host plants

74 plants in 23 families, most importantly crops of Brassicaceae family (Palumbo et al., 2016).
