Diagnosis

Rather small-sized (6–12 mm), dark brown variegated with black and white, tegmina usually with a white marking along costal margin on nodal line and posterior wings usually with a white marking near externoapical angle, sometimes orange on disc. The genus can be recognized by the following set of characters:

(1) gonostyli strongly sclerified and fused basally on about ½ of length

(2) gonostyli divided into a centroventral and a laterodorsal part

(3) gonostyli with laterodorsal part with large lateral process projecting laterally and bearing dorsoapical, articulate, spoon-shaped process

(4) aedeagus strongly reduced with dorsal portion of phallobase projecting dorsally as a spine or hook

The genus shares the condition of possessing a spoon-shaped process on the gonostyli with the Australian genera Chewobrachys Constant, 2008 , Fletcherobrachys Constant, 2006 , Hackerobrachys Constant, 2006 , Maeniana Metcalf, 1952 , Nirus Jacobi, 1928 and Stalobrachys gen. nov. but differs

– from Chewobrachys by its smaller size (6–12 mm; 12–16 mm in Chewobrachys ), the dark brown colour (greyish brown in Chewobrachys ) and the male gonostyli divided into a centroventral and a laterodorsal part (not divided in Chewobrachys )

– from Fletcherobrachys by the bright red abdomen (green to orange in Fletcherobrachys ), the hind wings brown or with discal orange marking (basal half white in Fletcherobrachys ), the absence of sexual dimorphism on median tibiae (with externodistal process in females of Fletcherobrachys ) and the male gonostyli fused only on basal ½ and divided into a centroventral and a laterodorsal part (fused along most of their length and not divided in Fletcherobrachys )

– from Hackerobrachys by the frons being brown and slightly convex (bright yellow to red and strongly convex in Hackerobrachys ), the posterior wings with some white and/or orange markings and rounded apically (uniformly brown with apex subquadrate in Hackerobrachys ) and the male gonostyli fused only on basal ½ and divided into a centroventral and a laterodorsal part (fused along most of their length and not divided in Hackerobrachys )

– from Maeniana by the pygofer having the posterior margin strongly sinuate (with elongate laterodorsal process projecting posteriorly in Maeniana ), the gonostyli fused on about ½ of their length (not or very shortly fused in Maeniana ), and the laterodorsal part of the gonostyli with a strong spine or hook and with the lateral process bearing a spoon-shaped process (laterodorsal part elongate and laminate, without spine or hook, and bearing a spoon-shaped process apically in Maeniana )

– from Nirus by the frons being slightly convex (concave in Nirus ), the pygofer broader on the dorsal ¾ (on ventral half in Nirus ), and the laterodorsal part of the gonostyli with a strong spine or hook and with the lateral process bearing a spoon-shaped process (laterodorsal part of gonostyli large and laterally compressed, not strongly sclerified and without a spine or hook in Nirus )

– from Stalobrachys gen.nov. by the narrower posterior wings with LW/BW =1.7–2.0 (1.5 in Stalobrachys gen. nov.), the pygofer with the posterior margin strongly sinuate (with elongate laterodorsal process projecting posteriorly in Stalobrachys gen. nov.), the gonostyli fused on about ½ of their length (not or very shortly fused in Stalobrachys gen. nov.), and the laterodorsal part of the gonostyli with a strong spine or hook and with the lateral process bearing a spoon-shaped process (laterodorsal part elongate and laminate, without spine or hook, and bearing a spoon-shaped process apically in Stalobrachys gen. nov.)

The genus Loisobrachys Constant, 2008 is known from a single female and was placed close to Hackerobrachys ( Constant 2008b) . Hence, the males of the genus potentially share the condition of possessing gonostyli with a spoon-shaped process. However, Olonia can easily be separated from Loisobrachys by its slightly convex frons (strongly convex in Loisobrachys ).

Historical review

1. Historical characters recognition review

Olonia was described by Stål (1862) within a key to the genera of Eurybrachidae without a spine under the eyes and with the clavus of the tegmina closed. From the key, the following characters could be extrapolated to define Olonia :

(1) posterior tibiae with 3 lateral spines

(2) frons transverse, with sides angulate

(3) pro- and mesonotum broader than combined length

(4) antennae short, placed under the eye

More recently, a key to the genera of Platybrachini was proposed by Fennah (1964), including Olonia for which the following distinctive combination of characters could be extrapolated:

(1) tegmina with CuA vein forked close to the nodal line

(2) tegmina with MP vein forked very close to the base

(3) genae without knob-like process under the eye

(4) frons more or less flat, without depressed areas near the base

(5) antennae not surpassing the eyes

(6) genital styles (= gonostyli) of male separated

Characters (2) and (6) are not correct: in Olonia , the MP is not forked very close to the base and Fennah’s statement probably comes from confusion with the ScP and RP, which diverge very basally, and the gonostyli in the male genitalia are fused basally.

2. Historical species review

Stål (1862) erected the genus Olonia for three species from Australia, Eurybrachys rubicunda Walker, 1851 , E. apicalis Walker, 1851 and E. transversa Walker, 1858 . The year after, Stål (1863) added one species from Queensland, O. viridiventris Stål, 1863 . Species were progressively added to the genus: O. picea by Kirkaldy (1906) (Queensland), O. marginata by Distant (1906) (Queensland), O. alboapicata and O. nigroapicata by Jacobi (1928) (Queensland and Western Australia, respectively), and O. ornata by Lallemand (1928) (Northern Territory). Jacobi (1928) synonymized O. picea Kirkaldy, 1906 with O. transversa ( Walker, 1858) , a view that I did not follow ( Constant 2005b), restoring O. picea as a separate species and considering O. transversa as a nomen dubium because the available specimen labelled as type in BMNH does not match the original description by Walker (1858). One last species, Cicada maura Fabricius, 1775 , was transferred to Olonia by Evans (1933) after being placed in the genus Eurymela Le Peletier & Serville, 1825 ( Cicadellidae : Eurymelinae ) for more than a century. Metcalf (1956) included 9 species in the genus in his catalogue of the Eurybrachidae . More recently, I transferred O. viridiventris Stål, 1863 to the genus Hackerobrachys Constant, 2006 and synonymized O. nigroapicata Jacobi, 1928 with Fletcherobrachys stillata (Bergroth, 1907) ( Constant 2006b) .

3. Historical classification review

The genus Olonia was placed by Schmidt (1908) in the tribe Platybrachini Schmidt, 1908 (equivalent to the present Platybrachinae, as the family Eurybrachidae was at that time treated as a subfamily of the Fulgoridae ) based on the following set of characters:

(1) clavus closed, with the claval veins (= Pcu and A1) fused before the apex of the clavus and Pcu +A1 reaching the apex of the clavus

(2) ventral margin of eyes without a spine

Metcalf (1956) placed the genus in the tribe Platybrachini of the Platybrachinae, a view followed by Fennah (1964).

SIZE. ♂: 6.2–10.1 mm; ♀: 7.2–11.2 mm.

Distribution

Australia: eastern and northern Queensland, also on islands ( Fig. 3 ).

Biology

According to the available data, species of Olonia seem to be present all year round and to be polyphagous, living on plants close to the ground. They were recorded from plants in the families Bursaceae, Convolvulaceae , Myrtaceae , Solanaceae , Urticaceae and Vitaceae . Known habitats range from open forests to beaches. All species seem to have a rather restricted distribution. Species of Olonia are present in all bioregions included in the distribution range of the genus ( Fig. 3B ).
