Macrosiagon dimidiata
wedge-shaped beetle
Macrosiagon dimidiata is a species of wedge-shaped beetle in the family Ripiphoridae, found in North America. Members of this family are characterized by their unusual body shape and parasitic or hypermetamorphic life histories. The species name 'dimidiata' refers to a divided or halved color pattern, though specific details of this marking are not well documented in accessible literature.
Macrosiagon excavata
Macrosiagon excavata is a species of wedge-shaped beetle in the family Ripiphoridae. It is native to South America, with specimens documented in museum collections from that region. The species was described by Klug in 1825. Like other members of the genus Macrosiagon, it is likely associated with the nests of solitary wasps, though specific host records for this species are not well documented.
Macrosiagon flavipennis
Macrosiagon flavipennis is a species of wedge-shaped beetle in the family Ripiphoridae. Originally described by LeConte in 1866 from North America, it has since been recorded from Central America and, more recently, from Chile—representing the first South American record for the species. Like other members of Ripiphoridae, its biology and ecology remain poorly known.
Ripiphorus
wedge-shaped beetles
Ripiphorus is a genus of wedge-shaped beetles comprising at least 30 described species. Members are parasitic beetles with highly modified body plans and complex life cycles involving multiple hosts. The genus has been recorded across multiple continents, with notable disjunct distributions including isolated volcanic archipelagos such as the Cape Verde Islands. Adults are typically short-lived and often associated with flowers, while larvae are parasitoids of other insects.
Ripiphorus epinomiae
Ripiphorus epinomiae is a species of wedge-shaped beetle in the family Ripiphoridae, first described by Linsley and MacSwain in 1950. It belongs to a genus whose members are known for their unusual biology, including hypermetamorphic development and parasitic relationships with bees. The species is documented from North America, though detailed ecological information remains limited.
Ripiphorus minimus
Ripiphorus minimus is a species of wedge-shaped beetle in the family Ripiphoridae, described by Pierce in 1904. Members of this genus are known for their unusual life history involving hypermetamorphosis and parasitoid relationships with other insects, particularly bees and wasps. The species is recorded from North America. Like other ripiphorids, adults are typically short-lived and do not feed.
Ripiphorus neomexicanus
Ripiphorus neomexicanus is a species of wedge-shaped beetle in the family Ripiphoridae, a group known for their unusual life history involving hypermetamorphosis and parasitism of other insects. The species epithet "neomexicanus" suggests a geographic association with New Mexico, though the full distribution and biology of this species remain poorly documented. Like other members of Ripiphorus, this species likely exhibits the family's characteristic extreme sexual dimorphism and complex larval development. The genus Ripiphorus is among the most derived lineages within the Ripiphoridae, with adults typically active during summer months.
Ripiphorus schwarzi
Ripiphorus schwarzi is a wedge-shaped beetle in the family Ripiphoridae, first described by LeConte in 1880. The species is known from North America. Members of this family are characterized by their unusual body shape and complex life histories involving parasitism of other insects.
Ripiphorus sexdens
Ripiphorus sexdens is a species of wedge-shaped beetle in the family Ripiphoridae. It is found in North America. Members of the genus Ripiphorus are known for their distinctive body shape and unusual life history strategies, though species-specific details for R. sexdens remain limited in published literature.
Trigonodera schaefferi
wedge-shaped beetle
Trigonodera schaefferi is a species of wedge-shaped beetle in the family Ripiphoridae, a family of beetles with unusual life histories involving parasitism or hypermetamorphosis. The species is known from North America and was described by Rivnay in 1929. Ripiphorid beetles are generally uncommon and poorly known, with most species having specialized host associations that remain incompletely documented.
