Subfamily Deltocephalinae: Tribe Hecalini
Hecalus arcuatus (Motschulsky)
The Australian Hecalini are mainly brightly coloured insects with an expanded crown. Some, such as Hecalus arcuatus, have distinctive markings making them instantly recognisable. Hecalus pallescens, a large cream coloured species, has the head laminately expanded and might be mistaken for a member of the Nirvaninae but lacks the carinate antennal ledges that are a feature of that subfamily. Zahniser and Dietrich (2013) recognised two subtribes in the tribe and the Australian fauna is all included in the Subtribe Hecalina. Most species appear to be grass-feeding. Although species of Hecalus can be quite common, no Australian species is known to have any economic importance.

Hecalus porrectus (Walker) Acocephalus
porrectus Walker 1858a: 262 Note: The source of the synonymy of T. albomaculata is uncertain. Neither Metcalf (1963) nor Evans (1966) listed the species as a synonym but it was listed as such by Morrison (1973) without the annotation "new synonymy" which was used for other synonyms. |

Reuteriella flavescens (Signoret) Reuteria flavescens Signoret 1880:
46 Note: Evans (1966: 136) casts doubt on this Australian record and it is therefore excluded from the Australian fauna until such time as a positive confirmation of a hecaline from Tasmania is made. |
