Mniothripa
Hampson
Type
species: lichenigera
Hampson, Singapore.
The forewings are of the narrow sarrothripine type and pattern, the postmedial
looping closely round a rather elongate, bilobed reniform, then being angled
back towards the dorsum. Both the anterior of the postmedial and the line of the
reniform are set obliquely to the costa. The venation is of the groundplan type,
with M3 and CuA1 of the hindwing stalked. The wings are mostly dark grey or
brownish grey.
The male abdomen is diagnostic, with a definite tymbal structure, sometimes with
lateral hair-pencils or coremata (Fig 127) that does not resemble that seen in
the Characoma group or indeed any other chloephorine. Another unusual
feature is the lack of apodemes on the eighth segment. The genitalia are also
unusual, with a strong, apically scobinate gnathus, a narrow, acute saccus, and
robust but narrow valves with a spatulate, setose apex. These setae are
deciduous, ventrally large, marginally small, the former on the exterior face of
the valve, but those in a zone along the dorsal margin of the sacculus are
moderate and not deciduous. However, the saccular shield and transtillar
development are typically nolid. The aedeagus vesica contains numerous cornuti
that can be deciduous.
The female genitalia have elongate, narrow ovipositor lobes and apophyses. The
ductus is usually narrow, the bursa pyriform, without signa.
The genus consists of the species described below and M.
viridisuffusa
Fletcher from Africa; Fletcher (1957) reviewed the genus, and determinations are
best made by dissecting the genitalia.
