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.

Description

Adult Steniini are characterised by long legs, and males typically have a slender, long abdomen. In the male genitalia, the uncus with its bifid chaetae is single or bicapitate (in Loxostegopsis and Tatobotys) or entirely split (in Metasia). The costa of the valva is concave or straight, in some taxa weakly convex. The valva itself is simple and usually lacks a fibula or exhibits a single fibula originating from base of valva; in the Duponchelia group,[2] two or three small fibulae are present at the base of the valva. The fibula and the dorsodistal sacculus or its extension are non-overlapping. The phallus has a caecum. In the female genitalia, a signum is generally absent except in Bradina and Perisyntrocha, where it forms a toothed arc. The ostium and ductus bursae lack any other sclerotization; the absence of sclerotisations in the corpus bursae is considered a synapomorphy of Steniini.[3] In the Duponchelia group, the forewing has vein Rs1 stalked with Rs2+3. A recurrent character in several but not all species of this group is the fovea in the male forewing at the distal end of the discal cell. In the male genitalia the dorsal vinculum exhibits a pair of elongate hairpencils. The ductus bursae in the female genitalia is very short. In the caterpillars, the mesothoracic SD2 seta is fine and hairlike.[2][3]

Food plants

Steniini caterpillars generally appear to feed on detritus. In Southeast Asia, the larvae of the Duponchelia group are detritivores in marshes and intertidal environments of mangrove swamps. They are often associated with the Avicennia zone of mangrove forests, which is inundated at high tides.[2][4]

Particular food records are known for only a few species:

Distribution

The genera Anageshna, Apogeshna, Loxostegopsis, Penestola and Steniodes are confined to the Americas, whereas Bradina and Dolicharthria can be found in both the Old and New World. The remaining genera are Old World taxa, with Epherema, Hymenoptychis, Symmoracma and Tatobotys primarily found in the tropics of Asia.[1]

The tribe currently comprises the following 15 genera, altogether containing 256 species:[1]
