Olonia marginata Distant, 1906: 206   (described).

Olonia marginata   – Kirkaldy 1907: 105 (listed from Queensland). — Metcalf 1956: 64 (catalogued).

Diagnosis

This species can be recognized by the following combination of characters:

(1) hind wings without orange marking ( Figs 16A View Fig. 16 , 20A View Fig. 20 )

(2) pro- and mesofemora and -tibiae largely black-brown ( Figs 16A –D View Fig. 16 , 20A –D View Fig. 20 )

(3) anal tube of male spatulate, constricted at basal ½ ( Fig. 19B View Fig. 19 )

(4) centroventral part of gonostyli with narrow and strongly elongated process that is sinuate basally and hooked apically ( Fig. 19A, C View Fig. 19 )

(5) laterodorsal part of gonostyli with narrow and strongly elongated process that is strongly curved posteroventrally ( Fig. 19A, C –D View Fig. 19 )

(6) rather small size: 6–8 mm

Etymology

The species epithet marginatus (adjective, Latin) means ʻmarginatedʼ, ʻborderedʼ. It refers to the darkened costal and apical margins of the tegmina.

Material examined

Lectotype AUSTRALIA • 1 ♀; Queensland; “Type”, “Type”, “ Olonia marginata   , type, Dist.”, “Queensland, F.P. Dodd, 1902 – 319”; here designated to provide a reference standard for this species; BMNH ( Fig. 15 View Fig. 15 ).  

Paralectotypes AUSTRALIA • 2 ♀♀; “ Queensland, F.P. Dodd, 1902 – 319 ”; BMNH.  

Note

In the collections of BMNH, there are 3 additional specimens identified by Distant but which are not part of the type series: 1 ♀, “ Olonia marginata Dist.   ”, “Townsville [19°25′26″ S, 146°56′44″ E] (Dodd)”, “B”, “Distant Coll. 1911-383”; 2 ♁♁, “ Queensland, F.P. Dodd, Brit. Mus., 1907—54 ”. GoogleMaps  

These specimens are particularly interesting because (1) they are from the same collector as the type series; (2) they provide Townsville as the location for the type series, where the collector, Frederick Parkhurst Dodd (1861–1937), lived at the time before moving to Kuranda and (3) there are two males, which allows a characterization of the species based on male genitalia. These males are used here as a reference for the recognition of this species.

Metacoxae reddish; metafemora reddish with apex brown. Metatibiae brown, with 3 lateral spines paler basally and 8 apical black-brown spines. Metatarsi brown, with a ventral row of 6 black spines on first tarsomere.

ABDOMEN ( Fig. 18F View Fig. 18 ). Bright red with genital segments black-brown.

MALE GENITALIA ( Fig. 19 View Fig. 19 ). Posterior margin of pygofer in lateral view strongly sinuate, strongly roundly projecting at dorsal ½, rather broad ventrally ( Fig. 19A, C View Fig. 19 ). Anal tube spatulate, 2.2 times as long as broad, laterally constricted at level of epiproct, slightly curved ventrally in lateral view; lateral margins slightly curved ventrally on apical ¾; apical margin rounded ( Fig. 19 A –B View Fig. 19 ). Gonostyli fused on basal third of length of centroventral part and projecting posteriorly ( Fig. 19A, C View Fig. 19 ). Centroventral part broad and dorsoventrally flattened on basal third, then strongly narrowing into a long spinose process strongly sinuate basally in lateral view and ending in narrow hook curved ventrally ( Fig. 19A, C View Fig. 19 ). Laterodorsal part of gonostyli strongly elongate and curved posteroventrally, surpassing level of centroventral part ventrally; lateral process elongate, projecting laterally and longer than spoon-shaped process ( Fig. 19A, C –D View Fig. 19 ). Dorsal portion of phallobase with hooked process on each side, progressively narrowing from base to apex, directed posterocentrally and with apex pointing dorsally ( Fig. 19E –F View Fig. 19 ). Ventral portion of phallobase trilobed in dorsal view, with median lobe surpassing phallus ( Fig. 19E –F View Fig. 19 ). Phallus dorsoventrally flattened, rather broad, with apical margin emarginate in middle ( Fig. 19E –F View Fig. 19 ).

Female

Similar to male, but with white spot at apicosutural angle of posterior wing reduced, extending on 1 cell ( Figs 15 View Fig. 15 , 20 View Fig. 20 ). Sometimes with a reduced white transverse band at basal ½ of tegmina visible in a marking along costal and sutural margins ( Fig. 21 View Fig. 21 ).

Nymph

HEAD ( Fig. 22 View Fig. 22 ). Brown, as broad as pronotum, frons flattened, with lateral rounded row of yellowish tubercles; group of yellowish tubercles dorsally on each side of joint between frons and vertex; clypeus reaching mesocoxae.

THORAX ( Fig. 22 View Fig. 22 ). Brown; pronotum short, with two dense rows of yellowish tubercles on each side; meso- and metanotum with a circular group of yellowish tubercles at base of wing buds and some tubercles near apex of wing buds.

LEGS ( Fig. 22 View Fig. 22 ). Brown slightly variegated with yellowish; large in comparison to body size. Anterior and median femora and tibiae broad and dorsoventrally flattened; posterior tibiae with three strong lateral spines.

ABDOMEN ( Fig. 22 View Fig. 22 ). Rather short, less than half as long as head and thorax combined, and narrower than thorax; pale yellowish bown with dorsal median line and apex darker. Live specimens with abdomen covered in white wax, except three apical segments with brown wax; each segment bearing a waxy plate on each side; two movable, very elongate, waxy filaments at apex of abdomen ( Figs 23B –C View Fig. 23 , 25B –C, K, N View Fig. 25 ).

Distribution and biology

This species is recorded from an area around Townsville in North Queensland ( Fig. 3 View Fig. 3 ), in the Einasleigh Upland Savanna, Queensland Tropical Rainforests and Brigalow Tropical Savanna bioregions. Adult specimens were collected in January, February, March, April, August, Sepember and October, while nymphs were observed in Feb. and Apr. ( Figs 23B –C View Fig. 23 , 25B –C, K View Fig. 25 ), and an egg mass in Apr. ( Fig. 23D View Fig. 23 ), leading to the conclusion that the species is probably present most of the year. A caterpillar of an unidentified species of Epipyropidae ( Lepidoptera   ) was observed on the back of a female specimen ( Fig. 23G View Fig. 23 ).

Olonia marginata   is polyphagous and has been collected or observed on Melaleuca quinquenervia (Cav.) S.T.Blake   ( Myrtaceae   ), Eucalyptus   sp. ( Myrtaceae   ) ( Fig. 25F View Fig. 25 ), Canarium australianum F.Muell.   (Bursaceae) ( Fig. 24 View Fig. 24 ), Vitis vinifera   L. ( Vitaceae   ), Pipturus argentaeus Wedd.   ( Urticaceae   ) ( Fig. 25G View Fig. 25 ), Corymbia tesselaris K.D.Hill & L.A.S.Johnson   ( Myrtaceae   ) ( Fig. 25E View Fig. 25 ) and in numbers on Ipomoea pescaprae   (L.) R.Br. ( Convolvulaceae   ) ( Figs 23B –D, F View Fig. 23 , 25B –D, I –K, M –O View Fig. 25 ), on stems and young branches with a thin skin.

It is interesting to note that the 2016 sampled locations in Magnetic Island and Townsville ( Figs 23A, E, H –J View Fig. 23 , 25A, H, L View Fig. 25 ) were all more or less destroyed by the Tropical Cyclone Yasi in Feb. 2011, which covered these habitats in smashing waves and left them buried under sand and beach debris (pers. com. V. Ryland, Feb. 2016). The species has, however, re-colonised the areas in less than five years, displaying a good degree of adaptation to habitat disturbance.
