Marasmianympha is a genus of moths of the grass moth family (Crambidae) described by Eugene G. Munroe in 1991. Its single species, Marasmianympha eupselias, was described by Edward Meyrick in 1929. Among the grass moths, it belongs to subfamily Spilomelinae. It is endemic to the Marquesas Islands of Polynesia, where it has been recorded on Fatu Hiva, Hiva Oa and Tahuata, but is suspected to occur on other islands as well. The holotype specimen is in the Natural History Museum, London. [1]
When first described, this moth was assigned to the genus Aulacodes in subfamily Acentropinae (then known as Nymphulinae). But eventually it was determined that despite a superficial similarity, M. eupselias is not a member of the Acentropinae, and hence by grass moth standards not at all closely related to Aulacodes.
M. eupselias is a smallish moth with fairly short antennae. It resembles Aulacodes in having labial palps which do not project straightly and have a very much reduced third segment. In the hindwings, the third and fourth veins do not originate at the same point, and the sixth vein approaches the common stalk from which veins 7 and 8 originate. [1]
The genitals can be used to reliably identify this species. In the male, the clasper's harpe is simple, with a slightly widened cucullus, and covered in long thin bristles. The uncus consists of two fingered processes which bear short thick bristles; the vinculum is triangular. The tegumen is almost square, and at the hind end of the upper side bears two groups of long, thick bristles; the anellus is small, flat, but notably sclerotized (hardened). The aedeagus is almost straight, robust, but not very long; the vesica bears two strong horns. [1]
In the female, the ostium is V-shaped. The ductus seminalis insert from sideways and above, near the expanded forward end of the ductus bursae. The latter is sclerotized and on the underside has two conspicuous fingered processes. The bursa copulatrix has a fine-grained wall, and the signum is a small sclerotized cone. [1]
Even though this moth was described almost a century ago and does not seem to be uncommon at least in the uplands of southern Fatu Hiva (where it has been collected numerous times), the ecology of this species is almost completely unknown. It is suspected to inhabit the more or less dense native woodland, and may have been driven to the uplands by deforestation for agriculture; the modern records of this species are generally from 600 m (c. 2000 ft) ASL to the mountain peaks. Plants that occur in its habitat are for example Bidens henryi , Cheirodendron bastardianum , Pandanus , and east Polynesian blueberry ( Vaccinium cereum ), as well as numerous other shrubs, ferns, mosses and lichens.

The Pyralidae, commonly called pyralid moths, snout moths or grass moths, are a family of Lepidoptera in the ditrysian superfamily Pyraloidea. In many classifications, the grass moths (Crambidae) are included in the Pyralidae as a subfamily, making the combined group one of the largest families in the Lepidoptera. The latest review by Eugene G. Munroe and Maria Alma Solis retain the Crambidae as a full family of Pyraloidea.
Fatu-Hiva is the southernmost island of the Marquesas Islands in French Polynesia, an overseas territory of France in the Pacific Ocean. With Motu Nao as its closest neighbour, it is also the most isolated of the inhabited islands.
Ethmiopsis is a genus of the twirler moth family (Gelechiidae). Among these, it was previously assigned to subfamily Pexicopiinae, but later moved to the Chelariini tribe.
Aulacodes is a genus of moths of the family Crambidae. The genus was first described by Achille Guenée in 1854.
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.
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.
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.
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.
Diaphania indica, the cucumber moth or cotton caterpillar, is a widespread but mainly Old World moth species. It belongs to the grass moth family, and therein to the large subfamily Spilomelinae. This moth occurs in many tropical and subtropical regions outside the Americas, though it is native to southern Asia; it is occasionally a significant pest of cucurbits and some other plants.
Epicephala spinula is a moth of the family Gracillariidae, one of the most primitive groups of ditrysian "micromoths". Within its family, it belongs to the subfamily Gracillariinae. Even though it was first scientifically studied in 1929, for many decades the specimens of this moth were mistaken for the related Australian species E. colymbetella, and their distinctness was only realized in 1986. It is found on the Marquesas Islands, where it occurs at least on Nuku Hiva, Ua Pou, and Fatu Hiva, and though little-known it is apparently not uncommon. The holotype specimen, a female, is USNM 100839.
Caloptilia insidia is a moth of the family Gracillariidae, one of the most primitive groups of ditrysian "micromoths". Within its family, it belongs to the subfamily Gracillariinae. It is apparently endemic to Fatu Hiva and Hiva Oa in the Marquesas Islands, French Polynesia. It is very similar to C. deltanthes. The species does not seem to be common, and no females appear to have been encountered yet.
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.
Zamagiria is a genus of small moths belonging to the snout moth family (Pyralidae). They are part of the huge snout moth subfamily Phycitinae, but their exact relationships are obscure, and they are currently not assigned to a particular tribe of Phycitinae.
Stangeia distantia is a moth species of the family Pterophoridae. It was first described in 1986 by J. F. Gates Clarke, and is known from Fatu-Hiva in the Marquesas Archipelago.
Ernophthora denticornis is a species of snout moth in the genus Ernophthora. It was described by Edward Meyrick in 1929. It is found on the Marquesas Archipelago in French Polynesia, where it is known from the islands Hiva Oa, Nuku Hiva, Tahuata, Ua Pou and Fatu-Hiva.
Lineodini is a tribe of the species-rich subfamily Spilomelinae in the snout moth family Crambidae.
