Introduction

This species was placed in Iolania Kirkaldy by Muir (1931) on the basis of the absence of hind tibial spines. He commented that the genitalia show little affinity with the Hawaiian species of the genus. Emeljanov (2000) considered Iolania to be absent from the Australian fauna but left two described Australian species in the genus. Löcker (2020) transferred both species to Australian genera with this species being placed in Leades Jacobi and the other into the new genus Yamirrina Löcker, leaving Iolania as an Hawaiian endemic. Leades clypealis has a disjunct distribution with an east coastal distribution from near Bundaberg in Queensland to Booti Booti National Park on the North Coast of New South Wales along with two records from central Australia, one near Alice Springs in the Northern Territory and the other in the Musgrave Ranges in the far north of South Australia.

Diagnosis

Colour. Frons, clypeus and genae dark brown or black, the lateral carinae of frons, the vertex, pronotum and tegulae yellow; mesonotum dark brown, legs light brown, abdomen dark brown, genitalia lighter. Tegmina hyaline, slightly stramineous, veins light, apical veins light brown, veins with fine granules bearing dark hairs. Wings hyaline with darkish veins. Morphology. Width of vertex slightly greater than length, apex slightly angular, base slightly emarginate; transverse carina slightly curved near apex, longitudinal median carina fine. Width of frons at apex greater than length in middle, widest at apex, median carina distinct, continued on to clypeus, no median ocellus; clypeus swollen, roundly produced into apex of frons (fronto-clypeal suture strongly curved), lateral carinae fine, median carina distinct; on middle line clypeus longer than frons. Claval veins forked in middle of clavus, Sc + R fork and Cu fork about the same level, M fork beyond nodal line. Hind tibial spines absent. Length: ♂ 2.3 mm; tegmen 3 mm. (Muir 1931).

With six (rarely seven) apical spines on the hind tibia and no platellae on the first hind tarsomere, this species has a similar chaetotaxy to Leades grandis Löcker, but is much smaller (males 3.5–4.1 mm in L. clypealis compared to 5.6–5.8 mm in L. grandis). These two species can also be distinguished by the colour of the lateral carinae on vertex and frons (yellow or light brown in L. clypealis; orange in L. grandis). The configuration of spines and ridges on the aedeagus matches that of Leades warro Löcker, however, these two species can be separated by the number of apical spines on the hind tibia (6–7 in L. clypealis; 8–10 in L. warro) (Löcker 2020)
