Wyoma is a small genus of the fungus moth family, Tineidae. Therein, it belongs to the subfamily Tineinae. It is probably fairly closely related to the type genus of its family and subfamily, Tinea , and can be most easily separated by the wing venation in Tinea, two veins in each wing arise from a common stalk, whereas none do in Wyoma. [1]

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Family is one of the eight major hierarcical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

In biological classification, a subfamily is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae".

Description

The head is bulging and has a rough, scaly and hairy surface, but the well-developed proboscis is devoid of scales. The labial palps droop; their second segment is longer than the third and has a clump of stout bristles at the tip, facing outside. The maxillary palps are long and usually carried tucked in. The antenna are unbranched and about as long as the forewing; the scape bears a flimsy comb. [1]

Proboscis an elongated appendage from the head of an animal, either a vertebrate or an invertebrate

A proboscis is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking. In vertebrates, a proboscis is an elongated nose or snout.

Antenna (biology) appendages used for sensing in arthropods

Antennae, sometimes referred to as "feelers", are paired appendages used for sensing in arthropods.

The forewings are narrow and have a rounded tip and 12 separate veins. Of these, vein 1b is simple, 2 starts near the angle of the wing, 7 reaches the leading edge near the tip and 11 starts from the basal fourth of the wing. Vein 4 is closer to 5 than to 3, and vein 10 is well separate from 9 and 11. The hindwings have only 8 veins, with the anal veins vestigal or absent. The hindwing veins are also all separated; vein 2 starts notably before the angle, while the position of vein 7 is equivalent to the forewing; veins 4-6 are evenly spaced, but vein 3 runs closer to vein 2. [1]

The male genitals are symmetrical and resemble those of Tinea ; they lack a socius, but gnathos and uncus are present. Female genitalia are not well described, but as dar as is known they differ markedly from those of Tinea. [1]

<i>Tinea</i> (moth) genus of insects

Tinea is a genus of the fungus moth family, Tineidae. Therein, it belongs to the subfamily Tineinae. As evident by its name, it is the type genus of its subfamily and family. Established as one of the very first subgroups of "Phalaena", it used to contain many species of Tineidae that are nowadays placed in other genera, as well as a few moths nowadays placed elsewhere.

Species

Only five species are contained in Wyoma: [2]

Blastobasidae family of insects

The Blastobasidae are a family of moths in the superfamily Gelechioidea. Its species can be found almost anywhere in the world, though in some places they are not native but introduced by humans. In some arrangements, these moths are included in the case-bearer family (Coleophoridae) as subfamily Blastobasinae. The Symmocidae are sometimes included in the Blastobasidae as subfamily or tribe.

Pityocona is a small and little-known genus of the twirler moth family (Gelechiidae). Among these, it is believed to belong to subfamily Gelechiinae, but beyond that its relationships are still obscure.

<i>Monopis obviella</i> species of insect

Monopis obviella is a species of tineoid moth. It belongs to the fungus moth family (Tineidae), and therein to the nominate subfamily Tineinae. It is the type species of Blabophanes, today treated as a junior synonym of the genus Monopis. M. crocicapitella was only separated from the present species in 1859, and is still frequently confused with it even by rather recent sources.

<i>Triaxomera parasitella</i> species of insect

Triaxomera parasitella is a species of tineoid moth. It belongs to the fungus moth family (Tineidae), and therein to the subfamily Nemapogoninae. It is widespread and common in much of western Eurasia, but seems to be absent from some more outlying regions, such as Portugal and the eastern Baltic, Ireland and Iceland. It has also not been recorded from Slovenia but given that it is found in neighboring countries, it may well occur there unnoticed. Recently, the species was recorded from British Columbia. Generally, it is a moth of warm temperate regions, e.g. in Great Britain it is only a rare and scarce species from the English Midlands northwards.

<i>Tinea pellionella</i> species of insect

Tinea pellionella, the case-bearing clothes moth, is a species of tineoid moth in the family Tineidae, the fungus moths. It is the type species of the genus Tinea, which in turn is the type genus of the subfamily, family, as well as the superfamily Tineoidea. Its scientific name is derived from "tinea", a generic term for micromoths, and the Latin term for a furrier, pellionellus.

Surattha is a genus of moths of the family Crambidae. The genus was synonymized with Prionapteryx by Stanisław Błeszyński in 1967. Its status was later revised by Graziano Bassi and Wolfram Mey in 2011.

Scirpophaga is a genus of moths of the family Crambidae described by Georg Friedrich Treitschke in 1832.

Tessema sensilis is a little-known moth species, the only member of genus Tessema. It belongs to the grass moth family (Crambidae), and therein to the large 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 detailed relationships are undetermined, it may be a close relative of Herpetogramma and/or Pilocrocis.

Clarkeophlebia is an enigmatic and almost-unknown gelechioid moth genus. It contains a single species, Clarkeophlebia argentea, and is apparently endemic to Fatu Hiva in the Marquesas Islands of Polynesia. It was originally described as Acanthophlebia, but this name had earlier been given to a genus of prong-gilled mayflies.

Asymphorodes is a gelechioid moth genus in subfamily Agonoxeninae of the palm moth family (Agonoxenidae), whose taxonomic status is disputed. Alternatively, the palm moths might be a subfamily of the grass-miner moth family (Elachistidae), with the Agonoxeninae becoming a tribe Agonoxenini.

Herlinda is a genus of cosmet moths. These moths were only discovered in 1968 and the genus was not described until 1986; its affiliations within the family are presently unknown. This genus, as far as is known, is endemic to the Marquesas Islands of Polynesia, with each species confined to a single island.

<i>Erechthias</i> genus of insects

Erechthias is a genus of the fungus moth family, Tineidae. Therein, it belongs to the subfamily Erechthiinae, of which it is the type genus. The exact circumscription of this genus is still disputed, but it may encompass more than 150 species.

<i>Monopis laevigella</i> species of insect

The skin moth is a species of tineoid moth. It belongs to the fungus moth family (Tineidae), and therein to the nominate subfamily Tineinae. It is the type species of the genus Monopis and its junior objective synonym Hyalospila. As with the common clothes moth, earlier authors frequently misapplied the name Tinea vestianella to the present species.

<i>Coleophora betulella</i> species of insect

Coleophora betulella is a moth of the family Coleophoridae. It is found in all of Europe, except the Balkan peninsula.

Phereoeca allutella, the household case-bearing moth, belongs to the subfamily Tineinae of the fungus moth family (Tineidae). It was first described by Hans Rebel in 1892. It is an occasional pest of furs, flannel and similar materials, and has been inadvertently introduced to many places it is not originally native to.

<i>Erechthias simulans</i> species of insect

Erechthias simulans is a species of fungus moth. It is here considered to belong to the somewhat controversial type genus of its subfamily Erechthiinae, though even fairly recently some authors have proposed to retain other genera such as Decadarchis separate from Erechthias. Decadarchis, with E. simulans as type species, would in fact contain this moth and its closest relatives, regardless whether it is recognized as full genus or as subgenus. These relatives are generally held to be a group of mainly Polynesian species. E. simulans has also been mistaken for a species of the closely related genus Comodica; while the delimitation of this versus Erechthias/Decadarchis is not universally agreed upon, E. simulans is not included in Comodica anymore by modern authors.

Phycitinae subfamily of insects

The Phycitinae are a subfamily of snout moths. Even though the Pyralidae subfamilies are all quite diverse, Phycitinae stand out even by standards of their family: with over 600 genera considered valid and more than 4000 species placed here at present, they unite up more than three-quarters of living snout moth diversity. Together with the closely related Epipaschiinae, they are apparently the most advanced lineage of snout moths.

<i>Autosticha</i> genus of insects

Autosticha is a genus of gelechioid moths. It belongs to the subfamily Autostichinae, which is either placed in the concealer moth family (Oecophoridae), or in an expanded Autostichidae. It is the type genus of its subfamily. Originally, this genus was named Automola, but this name properly refers to a fly genus in family Richardiidae.

<i>Tinea belonota</i> species of insect

Tinea belonota is a species of moth in the family Tineidae. It is endemic to New Zealand. It is classified as not threatened by the Department of Conservation.
