Halyini
Halyini is a tribe of stink bugs within the family Pentatomidae. The tribe has historically served as a provisional grouping for numerous genera, many of which have subsequently been reassigned to other tribes. Current taxonomy recognizes multiple genera within Halyini, including Halys and Neohalys, though the precise generic composition remains subject to revision. The tribe is characterized by morphological features of the male and female terminalia, which are important for species-level identification.
Halyomorpha halys
Brown Marmorated Stink Bug, BMSB
Halyomorpha halys is an invasive shield bug native to East Asia that has become a major agricultural and nuisance pest across North America, Europe, and beyond. First detected in Pennsylvania in 1998, it has spread to at least 47 U.S. states, 4 Canadian provinces, and numerous European countries. The species is highly polyphagous, feeding on over 300 plant species across 49 families, with particular preference for Rosaceae. Its invasion success is facilitated by high mobility, broad host range, and absence of natural enemies in invaded ranges. Natural control is emerging through adventive populations of the egg parasitoid Trissolcus japonicus and other native predators and pathogens.
Hexacladia
Hexacladia is a genus of gregarious endoparasitoid wasps in the family Encyrtidae, subfamily Encyrtinae. Species develop as endoparasitoids within adult heteropteran bugs, primarily in the family Pentatomidae (stink bugs), with some records from Coreidae and Scutelleridae. Multiple parasitoid individuals typically emerge from a single host. The genus has been documented as a biological control agent of agricultural pest stink bugs in South America, including species that attack soybean and rice crops. Seven species are recorded from South America, with H. smithii being the most widely reported.
Holcostethus
Holcostethus is a genus of shield bugs in the family Pentatomidae, subfamily Pentatominae. The genus comprises 18 described species distributed across multiple continents. Members of this genus share the characteristic shield-shaped body form typical of the family. Like other pentatomids, they possess scent glands that produce a defensive odor.
Hymenarcys nervosa
Nerve-winged Stink Bug
A species of stink bug in the family Pentatomidae, found in eastern North America. The common name refers to the distinctive venation pattern of the wings. Immature stages and egg morphology have been formally described, though detailed biological studies remain limited.
Hymenarcys reticulata
Hymenarcys reticulata is a species of stink bug in the family Pentatomidae, first described by Carl Stål in 1872. The species is known from both North and Middle America based on distribution records. As a member of the Pentatomidae, it belongs to a large family of true bugs characterized by shield-shaped bodies and scent glands. Specific biological details about this species remain poorly documented in available sources.
Kermana imbuta
Purple-washed Stink Bug
Kermana imbuta is a species of stink bug in the family Pentatomidae, known by the common name Purple-washed Stink Bug. It is distributed across Middle America and North America. The species was described by Walker in 1867. As a member of Pentatomidae, it possesses the characteristic shield-shaped body and scent glands typical of this family.
Lineostethus clypeatus
Lineostethus clypeatus is a species of stink bug in the family Pentatomidae, tribe Discocephalini. It was originally described by Stål in 1862. The species belongs to a genus characterized by a discoid head, a distinctive morphological feature among discocephaline genera. It is one of four previously recognized species in the genus Lineostethus, which was taxonomically revised in 2018.
Loxa
Loxa is a genus of shield bugs in the family Pentatomidae, tribe Pentatomini. Species in this genus are distributed primarily in Central America and Mexico, with records extending into Texas, Florida, and South America. Some species, particularly Loxa deducta, are recognized as minor crop pests.
