Bacotoma is a genus of moths in the subfamily Spilomelinae of the family Crambidae. It currently comprises 11 species, with an Oriental and Australasian distribution ranging from India and Sri Lanka over China and Southeast Asia to Australia. [1] [2]
The adults of Bacotoma have relatively narrow forewings and broad, almost triangular hindwings. Wing coloration is inconspicuous, with shades of brown and beige dominating. On the forewing, the antemedian and postmedian lines as well as the proximal and especially the distal discoidal stigma are distinct; on the hindwing, the postmedian line is prominent, and sometimes the discoidal stigma is well developed. Males have a long and slender abdomen with often prominent anal tufts and conspicuous patterns of black and white marks on the abdominal tergites 7 and 8, in some species also on tergite 6. The male genitalia are characterized by oval to lanceolate valvae with complex sclerotisations of the fibula and sacculus. The uncus exhibits two long, slender, apically tapering or somewhat inflated arms. The phallus or aedeagus is simple, sclerotized and contains a single needle-like cornutus. The female genitalia consist of a simple, sac-like corpus bursae with one or two small signa, a slender ductus bursae with granular texture and a small, sclerotized antrum. Characteristic for the genus are the pleural pockets of sternum 7, which are densely covered in short microtrichia. The pre-imaginal stages of Bacotoma have not been described.
Imagines of Bacotoma are superficially similar to those of Bradina , Herpetogramma and Syngamia , with which they share similar coloration and maculation. Identification of the adults and distinction from externally similar species is possible through genetical sequences, e.g. DNA barcoding, or genitalia dissection. In the genitalia, the genus is characterized by a number of putatively apomorphic features: in the male genitalia, the strongly bifurcate juxta with slender arms, each apically ending in a small hook, and the broad, lobate transtilla arms protruding dorsad beyond the costal valva edge; in the female genitalia, the pleural membrane of sternum 7 exhibits deep pockets covered in microtrichia.
Larvae of Bacotoma illatalis and B. ampliatalis have been reared from Celtis philippensis (Cannabaceae) and Strychnos minor (Loganiaceae) in Papua New Guinea. [2]
Spilomelinae is a very species-rich subfamily of the lepidopteran family Crambidae, the crambid snout moths. With 4,135 described species in 344 genera worldwide, it is the most speciose group among pyraloids.
The Azelinini are a tribe of geometer moths in the subfamily Ennominae, with many species in the Southern Hemisphere, particularly in South America. Several species are found in North America as well. These stocky geometer moths seem to be closely related to other robust tribes, such as the Campaeini, Ennomini, Lithinini and Nacophorini – all of which might warrant to be subsumed in the Ennomini – the genus Odontopera, and perhaps the Caberini and Colotoini. The tribe was first described by William Trowbridge Merrifield Forbes in 1948.
Chrysophyllis is a genus of the grass moth family (Crambidae). It is monotypic, containing the single species Chrysophyllis lucivaga. This moth is very little known, having only been recorded once, before 1935. It belongs to the large grass moth subfamily Spilomelinae; at the time of its description, these were still included in subfamily Pyraustinae and the entire Crambidae was then merged with the snout moths. While its exact relationships are undetermined, it is believed to be a close relative of Talanga. Like these, the male genitalia of C. lucivaga feature a remarkably elongated aedeagus shaped like a bullwhip.
Macrosoma conifera is moth-like butterfly described by Warren in 1897. It belongs to the family Hedylidae. Originally it belonged to the genus Phellinodes. Malcolm J. Scoble combined it with Macrosoma in 1986.
Macrosoma hedylaria is moth-like butterfly described by William Warren in 1894. It belongs to the family Hedylidae. Originally it belonged to the genus Phellinodes. Malcolm J. Scoble combined it with Macrosoma in 1986.
Charitoprepes apicipicta is a moth in the family Crambidae. It was described by Hiroshi Inoue in 1963 in the genus Heterocnephes, and was later moved to its current genus. The species is found in Japan (Honshu), China and Korea.
Eudonia cavata is a moth in the family Crambidae. It was described by Wei-Chun Li, Hou-Hun Li and Matthias Nuss in 2012. It is found in China.

Nistra is a genus of snout moths in the family Crambidae. It is monotypic, being represented by the single species Nistra coelatalis, which was formerly included in the genus Agrotera.

Lineodini is a tribe of the species-rich subfamily Spilomelinae in the snout moth family Crambidae.
Udeini is a tribe in the species-rich subfamily Spilomelinae in the pyraloid moth family Crambidae. The tribe was erected by Richard Mally, James E. Hayden, Christoph Neinhuis, Bjarte H. Jordal and Matthias Nuss in 2019.
Wurthiini is a tribe of the species-rich subfamily Spilomelinae in the pyraloid moth family Crambidae.
Steniini is a tribe of the species-rich subfamily Spilomelinae in the pyraloid moth family Crambidae. The tribe was erected by Achille Guenée in 1854.
Cheverella is a monotypic genus of snout moths in the subfamily Spilomelinae of the family Crambidae. It contains only one species, Cheverella galapagensis, which is endemic to the Galápagos Islands of Ecuador. Both the genus and the species were first described by Bernard Landry in 2011. The genus is placed in the tribe Udeini.
Portentomorphini is a tribe of the subfamily Pyraustinae in the pyraloid moth family Crambidae. The tribe was initially erected by Hans Georg Amsel in 1956.
