Taxonomy
editThe genus was first identified by Robert McLachlan in 1894, who used the spelling Pseudœconesus, and named Pseudoeconesus mimus as the type species.[2] Genetically, Pseudoeconesus forms a clade with three other Oeconesidae genera: Tarapsyche, Oeconesus and Zelandopsyche.[3]
Description
editMcLachlan's original text (the type description) reads as follows:
The species of this genus resemble Œconesus in a very remarkable manner, but the neuration of the ♂ is quite different. The characters here given are mainly comparative.
♂. Characters of antenne, palpi, legs, &c., practically the same. In the anterior wings there is no costal fold and no defined groove (present in Œconesus); the radius is confluent with the first apical sector (in both sexes and in both pairs, as in Œconesus); upper edge of discoidal cell excised (straight in Œconesus); apical forks Nos. 1, 2 and 3 present (irregular afterwards), the 6th apical cellule very much dilated at its base in a nearly circular manner. In the posterior wings apical forks Nos. 1, 2, 3 and 5 are present, and the neuration is apparently regular (but abnormally irregular on one side in the only male before me). ♀. The joints of the labial palpi shorter and broader, the terminal joint almost spoon-shaped. In the anterior and posterior wings apical forks Nos. 1, 2,3 and 5 are present, and the neuration appears to be normal and regular.
It appears to me probable that Œconesus and Pseudœconesus may have affinity with the group of genera represented by Goëra, Silo, &c.[2]
Distribution
editThe genus is found in New Zealand.[1]
