Introduction
This genus contains a single species based on a single female specimen. Nothing is known of the biology of the genus although it is suspected that it is associated with the plant genus Acacia Mill. as with related genera of Platybrachini. The etymology of Loisobrachys is given by Constant (2008) as "The name is formed by the juxtaposition of Lois, in honour of “Mother Fulgoromorpha”, Dr Lois B. O’Brien (USA), whom I wish to thank for her permanent and enthusiastic support, and brachys (Greek) = short, which is a common ending of the generic names among the Eurybrachidae. The gender is arbitrarily feminine following the use within the family."

Diagnosis
Small sized (8–9 mm), brown, convex insects. The genus can be recognized by the following combination of characters: (1) frons strongly convex, two times broader than long, (2) tegmina convex, (3) first fork of vein M before Sc-R separation, (4) first fork of Cu beyond level of A1-A2 fusion, (5) clavus closed, (6) hind wings well developed, brown without white or red marking, (7) abdomen and metasternum bright red, (8) ventral face of first hind tarsomere without pad of microsetae. Restricted to Australia. The only other Australian genus showing a strongly convex frons and no pad of microsetae on the first hind tarsomere is Hackerobrachys Constant, 2006, but it has flat tegmina, a more transverse vertex, the abdomen not red and the first fork of vein M beyond the Sc-R separation (Constant 2008)
