The Phycitinae are a subfamily of snout moths (family Pyralidae). 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. Phycitinae occur all over Earth's land masses, except in completely inhospitable areas; the majority of species has a tropical distribution however. Phycitinae have even been found on very remote oceanic islands, and a few species have been intentionally or unintentionally distributed by humans beyond their native range.〔Clarke (1986)〕 The type species of this subfamily is ''Phycita roborella'', under its junior synonym ''Tinea spissicella''. That name was apparently first proposed by J.C. Fabricius in his 1776/1777 ''Genera insectorum'' but overlooked by subsequent authors, leading to many sources listing its origin as Fabricius' 1790s work ''Entomologia systematica''. ==Description== In general, Phycitinae are smallish and slender-bodied moths, resembling fungus moths (family Tineidae) in appearance, though they have the well-developed proboscis typical of snouth moths and in many cases also the tell-tale "snout" consisting of elongated and straight labial palps. They are usually inconspicuous; while the forewings of some are quite prominently patterned, even these have usually rather nondescript greyish-brown colors and in the natural environment the pattern is cryptic. Yet a few species of Phycitinae, such as ''Oncocera semirubella'', are unusually bright-colored by moth standards, while those of genus ''Myelois'' resemble members of unrelated "micromoth" family Yponomeutidae and like these are called "ermine moths" due to their bright white forewings with tiny black spots. Despite their diversity, the group is considered by and large monophyletic as traditionally circumscribed. Due to the sheer number of taxa contained here, this has not been thoroughly tested, and some little-known genera traditionally included in the Phycitinae may of course simply be convergent and do not really belong here. Altogether however, the mesothorax of the caterpillars – with the sclerotised (hardened) ring around the base of seta SD1 – as well as the identical frenula of male and female adults' wings – a single bristle composed of several acanthae – are held to be characteristic autapomorphies by which the Phycitinae can be recognized. Furthermore, in the female genitalia of this subfamily the ductus seminalis originates in the corpus bursae. A useful character in the field is that the forewings of many adult Phycitinae lack one or more veins, usually the seventh one.〔Clarke (1986), Solis (2007)〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Phycitinae」の詳細全文を読む スポンサード リンク
