Cydnus
Cydnus is a genus of burrower bugs (Hemiptera: Cydnidae) in the tribe Cydnini, subfamily Cydninae. The genus was established by Fabricius in 1803 and is characterized by morphological features including pegs on head margins, hair-like setae on pronotum lateral margins, an anterior submarginal impressed line on the pronotum, and a triangular scutellum broader than long. The fossil genus Eocenocydnus shows affinity to Cydnus based on shared morphological traits.
Cyrtomenus
burrowing bugs, burrower bugs
Cyrtomenus is a genus of burrower bugs in the family Cydnidae, subfamily Cydninae, comprising approximately nine described species distributed in the Neotropics. Species in this genus are characterized by morphological adaptations for digging and exhibit polyphagous feeding habits. At least two species, C. bergi and C. mirabilis (now synonymized), are recognized as significant agricultural pests, particularly of cassava roots. The genus is distinguished among Neotropical Cydninae by the strongly flattened posterior tibia, a feature shared with the related genus Prolobodes.
Geotomini
Geotomini is a tribe of burrower bugs within the subfamily Cydninae. Members are ground-dwelling heteropterans with documented maternal care behaviors, including seed-carrying by females to provision nymphs. The tribe has been studied primarily through the species Melanaethus crenatus, with limited tribe-wide behavioral characterization.
Melanaethus crenatus
Melanaethus crenatus is a burrower bug (Hemiptera: Cydnidae) described by Signoret in 1883. The species exhibits distinctive maternal behavior in which females carry seeds to oviposition sites, a trait documented in a detailed study of its immature stages. The egg and five nymphal instars have been formally described.
Microporus nigrita
Microporus nigrita is a species of burrower bug in the family Cydnidae, order Hemiptera. The species was described by Fabricius in 1794 and is known from scattered records across northern Europe including Belgium, Norway, and Sweden. As a member of the burrower bug family, it is associated with soil habitats. The genus Microporus is characterized by small body size among cydnids.
Pangaeus
burrower bugs
Pangaeus is a genus of burrower bugs in the family Cydnidae (Hemiptera), comprising approximately 14 described species. Members are fossorial insects adapted for subterranean life, with species distributed across the Americas. The genus includes significant agricultural pests, most notably P. bilineatus, which damages peanut crops in the southeastern United States. Species exhibit morphological adaptations for burrowing, including stout, spiny forelegs.
