( Figure 5 ) Diagnosis . This species differs from other species in the genus in lacking dark markings on the head and in having the aedeagus with a preapical flange giving rise to a pair of elongate retrorse processes. Description . Length of male 3.2 mm , female 4.3 mm . Overall coloration pale stramineous; median part of crown, anterior part of pronotum and scutellum bright yellow; basolateral triangles of mesonotum orange. Crown ( Fig. 5B ) produced anteriorly at obtuse angle, slightly longer medially than next to eye. Forewing with second apical cell petiolate. Male 2S apodemes ( Fig. 5D ) very short, triangular, well separated at base. Pygofer lobe ( Fig. 5E ) narrowly rounded apically, margin unmodified. Subgenital plate ( Fig. 5G ) approximately twice as long as wide, lateral margin convex, with 5-6 macrosetae, apex narrowly rounded. Style preapical lobe acutely produced, apophysis slender, evenly curved laterad with five evenly spaced posteromedial teeth, apex narrowed to blunt tip ( Fig. 5G ). Aedeagus in lateral view ( Fig. 5H ) with dorsal apodeme relatively short and narrow, approximately parallel to shaft; shaft tapered in basal half, nearly parallel sided and distinctly sinuate in distal half with apex rounded; in ventral view ( Fig. 5G ) gradually and slightly tapered with lateral preapical flange giving rise to pair of long retrorse spines, apex rounded with pair of triangular preapical lateral teeth; gonopore elongate, extended from between base of lateral preapical processes to near apex. Female sternite VII posterior margin trilobed medially with median lobe longer and broader than lateral lobes ( Fig. 5I ). FIGURE 4. Mayawa brevicephala sp. nov. , male holotype.

I, abdominal sternite VII of female. Etymology . The species is named in honor of Kathy Hill, cicada expert and collector of the type series of this and many other new and interesting Australian leafhoppers. Material examined . Holotype male, AUSTRALIA : Northern Territory 76km E of Mataranka on Roper Bar Hwy. 14°54.888’S 133° 42.78’E 77m , 03 Feb 2006 K. Hill , D. Marshall , M. Moulds , coll at light at night ( MNT ) . Other material. 2 females , AUSTRALIA : Queensland 37.6 km west of Alpha (E. of Beta). approx 15km E of Jericho , 23º37.439’S 146º16.228’E 372 m , 3 Jan 2004 , K. Hill , D. Marshall , J. Cooley , M. Moulds , at lights ( QM , INHS ) . Notes . The two female specimens from Queensland closely resemble the male holotype from Northern Territory except for being much larger. These females are not treated as paratypes because of the considerable distance between collecting localities .
