Cicada maura Fabricius, 1775: 686 (described).
Cicada maura – Goeze1778: 158 (described, catalogued).— Fabricius 1781: 326 (described, catalogued); 1787: 272 (described); 1794: 40 (described). — Gmelin 1789: 2107 (described, catalogued). — Donovan 1805 (described, illustrated). — Turton 1806: 595 (described).
Cicada matura [sic] – Donovan 1820: 120 (described).
Eurymela maura – Signoret 1850: 507 (described (based on a misidentified specimen according to Distant 1908: 105), transferred to Eurymela ). — Walker 1852: 1149 (catalogued). — Kirkaldy 1906: 356 (listed).
Signoret (1850) based the transfer of this species to Eurymela ( Cicadellidae ) on a misidentified specimen ( Fig. 26 View 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 NHMW.
The species can be recognized by the following combination of characters:
(3) anal tube of male spatulate, constricted at half length ( Fig. 30B View Fig. 30 )
(4) centroventral part of gonostyli with strong elongate process tapering distally and with 4–5 apical teeth ( Fig. 30A, C View Fig. 30 )
(5) laterodorsal part of gonostyli with strong furcate process, elongate process strongly curved posterolaterally ( Fig. 30A, C–D View Fig. 30 )
(6) rather small size: 7–8 mm
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.
Lectotype ( here designated) AUSTRALIA • ♁; “Australia”, “63 47”, “BMNH(E) # 668802 ”; here designated to provide a reference standard for the species; BMNH ( Fig. 27 View Fig. 27 ) .
Paralectotype AUSTRALIA • ♀; “63 47”, “BMNH(E) # 668803 ”; BMNH ( Fig. 28 View Fig. 28 ).
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).

One male labelled “Sol. Is., Guadalcanar I. [sic], 1-1921, J.A. Kusche coll., Collection of W.M. Giffard” from the 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.
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.
HEAD ( Figs 27A–D View Fig. 27 , 29A–D View 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–D View Fig. 27 , 29A–D View 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, C View Fig. 27 , 29A, C View 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. 29E View 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–D View Fig. 27 , 29A–D View 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. 30 View Fig. 30 ). Posterior margin of pygofer in lateral view sinuate, strongly roundly projecting at dorsal ¼, moderately broad ventrally ( Fig. 30A, C View 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–B View Fig. 30 ). Gonostyli fused on basal 2/5 of length of centroventral part and projecting posterodorsally ( Fig. 30A, C View 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, C View 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–D View 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–F View Fig. 30 ). Ventral portion of phallobase unilobed in dorsal view, with median lobe surpassing phallus ( Fig. 30E– F View Fig. 30 ). Phallus dorsoventrally flattened, rather broad, with apical margin deeply emarginate in middle ( Fig. 30E–F View Fig. 30 ).
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. 31 View Fig. 31 ).
Distribution and biology
This species is currently recorded from an area around Cairns in North Queensland ( Fig. 3 View 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.
