Anacharis
Anacharis is a genus of parasitoid wasps in the family Figitidae, established by Dalman in 1823. The genus occurs in the Palaearctic and Indomalayan regions, with species documented from Europe, Norway, and Thailand. A 2018 taxonomic revision redescribed four previously known Palaearctic species and described three new species, including the first Indomalayan record for the genus. The genus was also subject to nomenclatural changes, including the synonymization of A. gracilipes with A. eucharoides and the transfer of A. flavidicornis to the genus Aegilips.
Anthaxia
Anthaxia is a large genus of jewel beetles (family Buprestidae, tribe Anthaxiini) containing numerous species distributed across the Palearctic, Nearctic, Afrotropical, and Indomalayan regions. The genus is divided into seven subgenera: Anthaxia (Anthaxia), Haplanthaxia, Melanthaxia, Cratomerus, Merocratus, Thailandia, and Richteraxia. Species are primarily associated with woody host plants, with larvae developing in dead branches or living stems of various trees and shrubs. Adults are frequently observed visiting flowers, where they feed on pollen and nectar.
Apicotermitinae
Typical Soldierless Termites and Allies
Apicotermitinae is a highly diverse subfamily of termites within Termitidae, comprising 64 genera and 236 species distributed across the Neotropical, Afrotropical, and Indomalayan realms. The subfamily is predominantly soil-feeding, with most species inhabiting diffuse subterranean nests. A defining feature of most Apicotermitinae is the evolutionary loss of the soldier caste, which occurred independently in at least two separate lineages. In the absence of soldiers, workers have evolved alternative defense mechanisms including increased aggression and autothysis.

Eucosma is a large genus of small tortricid moths with at least 670 described species worldwide. The genus has a Holarctic and Indomalayan distribution, with approximately 150 species in the Nearctic region and 53 in Europe. New species continue to be discovered even in well-studied regions. Species exhibit considerable variation in coloration, ranging from plain to boldly patterned.
Eulichadidae
Forest Stream Beetles
Eulichadidae is a small family of beetles within Elateriformia, comprising two extant genera with contrasting distributions: Eulichas (Indomalayan realm, Asia) and Stenocolus (Western North America). Adults are terrestrial, while larvae are obligately aquatic in forest streams. The family exhibits notable ecological divergence between genera in habitat use and adult behavior.
Haplostethini
metallic wood-boring beetles
Haplostethini is a tribe of jewel beetles (family Buprestidae) within the subfamily Polycestinae. The tribe comprises at least 10 genera and more than 60 described species. Members are small to moderately sized metallic wood-boring beetles distributed across multiple continents. The genus Mastogenius is the most well-known in North America, with species occurring in the southwestern United States and Mexico. The tribe was established by LeConte in 1861.
Marathyssa
Beautiful Marathyssa Moth (for M. pulcherrimus)
Marathyssa is a genus of moths in the family Euteliidae, established by Francis Walker in 1865. The genus contains approximately 20 described species distributed across the Americas, Africa, and Asia. Several species occur in North America, including the type species M. basalis. The genus has been subject to taxonomic revision, with some sources historically placing it in Noctuidae.
Platynotini
Platynotini is a tribe of darkling beetles within the family Tenebrionidae, containing more than 70 genera distributed across multiple biogeographic regions including North and South America, the southern Palaearctic, the Afrotropical region, and the Indomalayan realm. The tribe is distinguished from other Blaptinae tribes by the presence of a stridulatory gula used for sound production. Recent molecular phylogenetic studies have strongly supported the monophyly of Platynotini. Members of this tribe exhibit considerable morphological diversity, with some African species such as Anomalipus being heavily built and armored, adapted to dense bush-covered savanna habitats.
Polyommatinae
Blues
Polyommatinae, commonly known as the blues, is a diverse subfamily of gossamer-winged butterflies within the family Lycaenidae. The group was established in 1775 and takes its name from the type genus Polyommatus, referring to the ocelli (eye spots) on their wings. Males of most species exhibit distinctive blue coloration on the upper wing surfaces, while females are typically brown with blue scales limited to the wing bases. The subfamily contains four recognized tribes: Candalidini, Lycaenesthini, Niphandini, and Polyommatini, with the latter comprising the majority of genera and species. Despite being one of the most species-rich groups within Lycaenidae, Polyommatinae has been historically understudied and its phylogenetic relationships remain in need of revision.
Sycoscapter
Sycoscapter is a genus of non-pollinating fig wasps first described by Saunders in 1883. These wasps are native to the Afrotropical, Indomalayan, and Australasian biogeographic realms. They function as parasitoids, specifically targeting fig wasps in the genera Ceratosolen, Eupristina, and Kradibia. As members of the family Pteromalidae, they represent one of many lineages involved in the complex ecological networks associated with fig trees (Ficus).
