== Description == Species of ''Erotides'' are medium-sized lycid beetles with elongated, somewhat flattened bodies. The elytra are strongly costate and reticulate, forming the characteristic net-like pattern typical of the family Lycidae.<ref name="Waterhouse-different-1879" /> Like other lycid beetles, members of ''Erotides'' are chemically defended and unpalatable, and they are believed to participate in Müllerian and Batesian mimicry complexes with other beetles and insects.<ref name="Bocák-2008a">{{cite journal |last1=Bocák |first1=Ladislav |last2=Bocáková |first2=Milada |last3=Hunt |first3=Tristan |last4=Vogler |first4=Alfried P. |year=2008 |title=Multiple ancient origins of neoteny in Lycidae (Coleoptera): consequences for ecology and macroevolution |journal=Proceedings of the Royal Society B: Biological Sciences |volume=275 |issue=1646 |pages=2015–2023 |doi=10.1098/rspb.2008.0476 |bibcode=2008PBioS.275.2015B}}</ref>
== Taxonomy == The genus ''Erotides'' was established by Charles Owen Waterhouse in 1879 in his revision of forms within the family Lycidae.<ref name="Waterhouse-different-1879">{{cite journal |last=Waterhouse |first=Charles Owen |author-link=Charles Owen Waterhouse |year=1879 |title=On the different forms occurring in the Coleopterous family Lycidae |journal=Transactions of the Entomological Society of London |volume=1879 |pages=95–118}}</ref> It has consistently been placed within the tribe Erotini, a group of lycid beetles noted for their frequent participation in mimicry complexes and shared aposematic colour patterns.<ref name="Bocák-2008a"/> Species limits and generic placement have been refined through regional revisions in Southeast Asia and the Papuan region, notably by Pic and Kleine in the early 20th century.<ref name="Kleine-1926">{{cite journal |last=Kleine |first=R. |year=1926 |title=Die Lyciden der Papuanischen Region |journal=Nova Guinea |volume=15 |pages=1–112}}</ref>
=== Taxonomic history === Waterhouse's original concept of ''Erotides'' was based on material from the Indo-Australian region and distinguished by strongly costate, reticulate elytra and serrate antennae.<ref name="Waterhouse-different-1879" /> Subsequent authors, including Maurice Pic, described additional species from Southeast Asia and the Philippines, occasionally proposing separate genera for regional forms. These were later synonymised as part of broader revisions of Lycidae, particularly in the work of R. Kleine<ref name="Kleine-1926" /> and later catalogued by Sergei V. Kazantsev.<ref name="Kazantsev-2013">{{cite journal |last=Kazantsev |first=Sergei V. |year=2013 |title=Lycidae of the world |journal=Zootaxa |volume=3658 |issue=1 |pages=1–172 |doi=10.11646/zootaxa.3658.1.1 |pmid=25333087}}</ref> Modern classifications retain ''Erotides'' as a valid genus within Erotini, based on adult morphology and comparative studies of Lycinae lineages.<ref>{{cite journal |last1=Bocák |first1=Ladislav |last2=Bocáková |first2=Milada |year=2008 |title=Phylogeny and classification of Lycidae (Coleoptera) |journal=European Journal of Entomology |volume=105 |issue=4 |pages=695–720}}</ref>
== Distribution == The genus is distributed in the Oriental and Australasian regions, with records from Indonesia, Malaysia, the Philippines, and Papua New Guinea.<ref name="Kleine-1926"/><ref name="Kazantsev-2013" />
== Biology and ecology == Specific biological data on ''Erotides'' are limited. In common with other Lycidae, larvae are thought to develop in decaying wood, leaf litter, or soil, where they feed on fungi or decomposing organic matter.<ref name=Bocák-2008/>
== Species == The following species are currently placed in the genus ''Erotides'':<ref name="Kazantsev-2013" /> {{linked species list |Erotides costipennis |Waterhouse, 1879 |Erotides flavicollis |(Pic, 1921) |Erotides sumatrensis |Pic, 1921 |Erotides javanus |Pic, 1921 |Erotides borneensis |Pic, 1923 |Erotides luzonicus |Pic, 1925 |Erotides mindanaoensis |Pic, 1925 |Erotides papuanus |Kleine, 1926 |Erotides celebensis |Kleine, 1930 }}
