Note

Signoret (1850) based the transfer of this species to Eurymela  ( Cicadellidae  ) on a misidentified specimen ( Fig. 26View Fig. 26). This specimen indeed belongs to the tribe Eurymelini, identified as a member of the genus Platyeurymela Evans, 1933  or Pauroeurymela Evans, 1933  by M.J. Fletcher (pers. com., Apr. 2016) based on the examination of photographs of the specimen in NHMWAbout NHMW.

Diagnosis

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

(1) hind wings without orange marking ( Figs 29EView Fig. 29, 31EView Fig. 31)

(2) pro- and mesofemora and -tibiae largely dark brown ( Figs 29A–DView Fig. 29, 31A–DView Fig. 31)

(3) anal tube of male spatulate, constricted at half length ( Fig. 30BView Fig. 30)

(4) centroventral part of gonostyli with strong elongate process tapering distally and with 4–5 apical teeth ( Fig. 30A, CView Fig. 30)

(5) laterodorsal part of gonostyli with strong furcate process, elongate process strongly curved posterolaterally ( Fig. 30A, C–DView Fig. 30)

(6) rather small size: 7–8 mm

Females of O. maura  are nearly impossible to separate from females of the sympatric O. picea  and should be identified only if collected together with males.

Etymology

The species epithet maurus (adjective, Latin) means ʻMoorʼ, the inhabitants of North Africa, and by extension, ʻdark skinnedʼ. It refers to the dark colour of the species.

Material examined

Lectotype ( here designated) AUSTRALIA • ♁; “Australia”, “63 47”, “BMNH(E) # 668802 ”; here designated to provide a reference standard for the species; BMNH ( Fig. 27View Fig. 27)  .

Paralectotype AUSTRALIA • ♀; “63 47”, “BMNH(E) # 668803 ”; BMNH ( Fig. 28View Fig. 28). 

Note

The lectotype and paralectotype are placed together in the Banks collection under two labels: “ Cicada maura, Fab. Entom.  p. 686.24”, “ Type ”. The specimens were collected by Joseph Banks and his team at the mouth of the Endeavour River (coordinates: 15°27′32″ S, 145°13′28″ E), when Captain James Cook’s ship Endeavour was beached and repaired, 17 Jun.–4 Aug. 1770 ( Banks 1771).GoogleMaps

Note

One male labelled “Sol. Is., Guadalcanar I. [sic], 1-1921, J.A. Kusche coll., Collection of W.M. Giffard” from the BPBMAbout BPBM has also been examined. This record from the Solomon Islands, very far off the Australian coast, is regarded as highly doubtful and a probable case of mislabeling.

Description

MEASUREMENTS AND RATIOS. LT: ♁ (n = 3): 7.2 mm (6.9–7.5); BV/LV = 3.6; BF/LF = 1.82; LP+ LM/BT = 0.62; Ltg/BTg = 2.4; LW/BW = 1.97.

Male

HEAD ( Figs 27A–DView Fig. 27, 29A–DView Fig. 29). Vertex slightly concave, with anterior and posterior margins parallel, curved; medium to dark brown with sides slightly darker. Frons uniformly coloured, medium to dark brown. Clypeus elongate, entirely brown. Genae brown to black with yellowish markings along anterior margin. Labium brown to black, reaching metacoxae. Antennae black-brown; scape short, ring-shaped; pedicel subcylindrical, slightly narrowing towards apex.

THORAX ( Figs 27A–DView Fig. 27, 29A–DView Fig. 29). Pronotum uniformly brown, sometimes variegated with yellowish; slightly wrinkled; 2 small impressed points on disc slightly marked; sometimes very obsolete median carina. Lateral fields of prothorax coloured as pronotum. Mesonotum medium to dark brown, somewhat darker than pronotum, sometimes variegated with yellowish; yellowish minute spot at apex of scutellum; median and peridiscal carinae weakly marked; median carina stopping before scutellum; slight impression before scutellum. Red ventrally. Tegulae medium to dark brown.

TEGMINA ( Figs 27A, CView Fig. 27, 29A, CView Fig. 29). Medium to dark brown; often pale yellowish marking on vein A1 at midlength of clavus; marked with dark brown or black along costal margin, more broadly so on posterior half, and along posterior margin. Often darker, median, irregular marking at apical ¾; triangular white marking on costal margin on nodal line, sometimes reduced; sometimes, a number of minute white spots at apicosutural angle. Costal and sutural margins subparallel; costal margin nearly straight; apical margin obliquely rounded.

POSTERIOR WINGS ( Fig. 29EView Fig. 29). Brown, paler on anal area and progressively darker on apical half; small, subtriangular white marking at apicocostal angle, extending on 2–4 cells. Margin of anal area slightly sinuate; sutural margin with 1 slight cleft, cubital one nearly not marked.

LEGS ( Figs 27A–DView Fig. 27, 29A–DView Fig. 29). Pro- and mesocoxae black-brown. Pro- and mesofemora black-brown variegated with brown. Pro- and mesotibiae medium to dark brown, sometimes with 3 paler obsolete rings. Pro- and mesotarsi black-brown with basal half of third tarsomere paler. Metacoxae reddish brown; metafemora reddish with apex brown. Metatibiae brown, with 3 lateral spines paler basally and 9 apical black-brown spines. Metatarsi brown with a ventral row of 6 black spines on first tarsomere.

ABDOMEN. Bright red with genital segments black-brown.

MALE GENITALIA ( Fig. 30View Fig. 30). Posterior margin of pygofer in lateral view sinuate, strongly roundly projecting at dorsal ¼, moderately broad ventrally ( Fig. 30A, CView Fig. 30). Anal tube with lateral margins parallel before epiproct, constricted at level of epiproct, then obovate in apical half, 1.95 times as long as broad, slightly curved ventrally in lateral view; apical margin rounded ( Fig. 30A–BView Fig. 30). Gonostyli fused on basal 2/5 of length of centroventral part and projecting posterodorsally ( Fig. 30A, CView Fig. 30). Centroventral part broad and dorsoventrally flattened on basal 2/5, then with 2 strong divergent processes projecting posterodorsally, with apex curved ventrally and bearing 4–5 strong teeth ( Fig. 30A, CView Fig. 30). Laterodorsal part of gonostyli elongate and directed posterolaterally, dorsoventrally flattened, shorter than centroventral part and strongly bifid, apically with the two processes subparallel; lateral process elongate, projecting anterolaterally and about as long as spoon-shaped process ( Fig. 30A, C–DView Fig. 30). Dorsal portion of phallobase with hooked process on each side, progressively narrowing from base to apex, directed posterocentrally, slightly converging posteriorly, curved in dorsal view and with apex pointing dorsally ( Fig. 30E–FView Fig. 30). Ventral portion of phallobase unilobed in dorsal view, with median lobe surpassing phallus ( Fig. 30E– FView Fig. 30). Phallus dorsoventrally flattened, rather broad, with apical margin deeply emarginate in middle ( Fig. 30E–FView Fig. 30).

Female

Similar to male, but without white spot on costal margin of tegmina at nodal line and with white spot at apicosutural angle of posterior wing strongly reduced, visible as a small, slightly paler marking ( Fig. 31View Fig. 31).

Distribution and biology

This species is currently recorded from an area around Cairns in North Queensland ( Fig. 3View Fig. 3), in the Cape York Peninsula Tropical Savanna and Queensland Tropical Rainforests bioregions. Specimens were collected in March, April, June, July and August. One specimen was collected on Solanum tubiferum  L. ( Solanaceae  ) and one on Eucalyptus  sp.
