Trichochrysea hirta is a species of leaf beetle found in Indonesia and Peninsular Malaysia in Southeast Asia. It has a metallic blue or green body covered with white hair, after which the species gets its scientific name: the species epithet, hirta, is derived from the Latin hirtus, meaning "hairy". [4]
The adult of Trichochrysea hirta has a metallic blue or green body, with dense white pubescence. Its head is coarsely punctured. The basal four or five segments of the antennae are rufo-piceous beneath, the second and third sometimes entirely so, the basal segment cupreo-aureus. [5] [6] It measures 5.8–10.0 mm in length. [1]
The species was first described from Sumatra as Eumolpus hirtus by Johan Christian Fabricius in his 1801 Systema eleutheratorum. [7] The species is currently a member of the genus Trichochrysea in the subfamily Eumolpinae.
Two subspecies of Trichochrysea hirta are recognised in Volume 6 of the Catalogue of Palaearctic Coleoptera: [2]
In 1987, two different subspecies of Trichochrysea hirta were recognised: T. h. hirta and T. h. nitidissima, with T. h. viridis as a synonym of the former. These differed mainly in the colour of the upper side. In 2007, T. hirta was instead divided into two species, based on differences in the shape of the aedeagus: specimens from Indonesia and Peninsular Malaysia (which have an aedeagus with an acute triangular apex) were considered true T. hirta, while those from mainland Asia (which have a broad aedeagus with truncated apex, with a small central tip) were now considered a separate species with the name Trichochrysea nitidissima . [1] The taxonomic position of the subspecies T. h. viridis is not clear, as its aedeagus was not studied: it is sometimes instead recognised as a separate species (Trichochrysea viridis), [8] but it is possibly a synonym of T. hirta. [1]
Trichochrysea hirta is recorded from Malacca, Sumatra, Bali, Lombok, Java, Nias, and Sulawesi. [9]
Colasposoma viridicoeruleum is a species of beetle belonging to the family Chrysomelidae, described by Victor Motschulsky in 1860. It is known as a pest of sweet potatoes. The species was formerly known as Colasposoma auripenne until 2003, when C. auripenne was determined to be a synonym of C. viridicoeruleum. It is sometimes considered a southern subspecies of Colasposoma dauricum, using the name Colasposoma dauricum auripenne.
Platycorynus is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in Africa and Asia.
Colaspoides is a genus of leaf beetles in the subfamily Eumolpinae. It is one of the largest genera in the subfamily, containing over 260 species worldwide. It is an extant genus but there is at least one species, C. eocenicus, found in Baltic amber from the Upper Eocene of Russia, and the genus has also been reported from the Miocene of the Dominican Republic.
Macrocoma is a genus of leaf beetles in the subfamily Eumolpinae. It contains about 100 species, which are found in tropical Africa, around the Mediterranean, on the Canary Islands, in western and central Asia, and in India.
Demotina is a genus of leaf beetles in the subfamily Eumolpinae. There are over 50 described species in Demotina. The genus is native to Asia, Australia and Oceania, though one species is an adventive species in the southeastern United States in North America. Some species are known to be parthenogenetic.
Typophorus is a genus of leaf beetles in the subfamily Eumolpinae. There are at least 52 described species in Typophorus. Similar genera include Paria and Tijucana. Typophorus itself is probably polyphyletic.
Typophorini is a tribe of leaf beetles in the subfamily Eumolpinae. The tribe contains approximately 100 genera, which are found worldwide. Members of the tribe are mainly characterized by notches on the tibiae of the middle and hind legs, which are sometimes referred to as antenna cleaners. They also generally have a subglabrous body, as well as bifid pretarsal claws.
Hyperaxis is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in East and Southeast Asia.
Tricliona is a genus of leaf beetles in the subfamily Eumolpinae. It contains at least 35 species, and is distributed from India and Southern China to the Philippines and New Guinea.
Basilepta is a genus of leaf beetles in the subfamily Eumolpinae. It is generally distributed in Asia. A single species is also known from central Africa.
Cleorina is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Australia and Asia.
Aulexis is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in East and Southeast Asia. The related genus Goniopleura is sometimes included as a subgenus.
