Mayawa bimaculata sp. nov.

( Figure 3 View FIGURE 3 )

Diagnosis. This species differs from all other known Mayawa species in having a pair of large maculae on the crown and the paired processes on the aedeagus greatly reduced and inconspicuous.

Description. Length of male 2.9 mm, female 3.8 mm. Overall color stramineous, head with pair of black maculae extended from between ocelli onto anterior half of crown, face ( Fig. 3C View FIGURE 3 ) unmarked except muscle scars on frontoclypeus slightly darker than adjacent parts; pronotum light grey posteromedialy; mesonotal triangles bright orange; forewing membrane light brown contrasting with pale stramineous wing veins; abdominal tergites brown, ovipositor blackCrown ( Fig. 3B View FIGURE 3 ) produced anteriorly at obtuse angle, slightly longer medially than next to eyes. Forewing with second apical cell petiolate basally.Male pygofer lobe ( Fig. 3E View FIGURE 3 ) narrowly rounded distally, margin unmodified. Subgenital plate ( Fig. 3F View FIGURE 3 ) approximately twice as long as wide, lateral margin weakly convex, with 5–6 macrosetae, apex obliquely rounded. Style preapical lobe acutely produced, apophysis narrow, elongate, evenly curved laterad, nearly parallel-sided, with five blunt, evenly spaced preapical teeth, apex bluntly rounded ( Fig. 3F View FIGURE 3 ). Aedeagus with dorsal apodeme approximately parallel to shaft in lateral view ( Fig. 3H View FIGURE 3 ), shaft evenly tapered from base to apex, slightly sinuate in lateral view; in ventral view ( Fig. 3G View FIGURE 3 ) shaft parallel-sided with pair of very short, inconspicuous retrorse lateral spines near midlength and pair of small lateral teeth near apex, apex rounded; gonopore relatively short, ovoid, situated near apex. Female sternite VII posterior margin trilobed medially with medial lobe shorter and narrower than lateral lobes ( Fig. 3I View FIGURE 3 ). First valvula dorsal sculpture squamiform, merging with ventral sculpture near apex ( Figs 3 View FIGURE 3 J–K). Second valvulae with median dorsal tooth moderately prominent, distal teeth irregular ( Figs 3 View FIGURE 3 L–M).

Etymology. The species name is a Latinized adjective referring to the pair of maculae on the crown.
