TACHINIDAE: Tachininae: Occisorini: Plethochaetigera Malloch, 1938

Plethochaetigera fenwicki Malloch, 1938, orig. des. [Type missing, supposedly in Malloch collection USNM (Miller, 1950). Paratype in NZAC].


Characteristics of Plethochaetigera include: 1. Body size 9 –13mm. Note: This genus keys out together with Chaetopletha, Neotachina, Phaoniella, Platytachina, and Tachineo. It is considerably difficult to find satisfactory external characters to distinguish these genera in a dichotomous key. This difficulty is expressed by Malloch 1938 several times over as well as by Dugdale 1969. A thorough revision at the genus level is needed that includes molecular analysis, rearing and collecting of new material.
