Eugoa hectogamoides sp. n.


Eugoa hectogamoides (holotype)
(x 1.56)


8mm. The ground colour is pale straw, the forewing rather narrow, irrorated with darker brown which is concentrated more basally. There is a dark brown discal mark and an irregular submarginal of the same colour. The genitalia indicate a relationship with the type species of Hectogama which has facies more as in pseudarcuata. Shared features include: a pair of scent pencils arising from small discs of setal bases on the intersegmental membrane close to the saccus; a juxta terminating dorsally in a pair of appressed rods; a rather characteristic valve shape with a dentate apex and a distinctive subapical zone of setae. The valve apex is narrower, unidentate, in hectogamoides, and the aedeagus vesica has many cornuti rather than one large one.
