Introduction

Ectinorhynchus is being revised by Lambkin and currently contains 15 described and at least 20 undescribed species from Australia and New Zealand. Ectinorhynchus is referred to here in its broadest sense. Close relatives to Ectinorhynchus such as Melanothereva, Pachyrrhiza and Entesia are found in Chile and undescribed genera and species are known from New Caledonia. Males of some species of Ectinorhynchus form small swarms in open areas awaiting females.

Diagnosis

Antennae elongate; single row of postocular setae in male; cell m3 open; hind femur with anteroventral apical seta; velutum patches absent on fore femora; gonocoxites with medial atrium; dorsal apodeme of parameral sheath 'T'-shaped; distiphallus often with lateral flanges and spines; spermathecal sac trilobate, spermathecal duct on each spermathecal sac duct; three spermathecae. Some Ectinorhynchus have velutum patches on the ventral surface of hind femora and gonocoxites, previously considered to be a diagnostic character for the subfamily Agapophytinae.
