Mayawa affinifacialis

sp. nov.

Mayawa affinifacialis   sp. nov.

( Figure 2 View FIGURE 2 )

Diagnosis. This species closely resembles M. facialis Fletcher   but differs in having the face relatively pale, without dark brown pigmentation, the male style apophysis thinner and more elongated, and the gonopore of the aedeagus arising farther from the apex.

Description. Length of male 3.8 mm. Ground color dull stramineous, marked with brown. Crown ( Fig. 2B View FIGURE 2 ) uniformly stramineous except indistinct anterior submarginal broken transverse light brown band; face ( Fig. 2C View FIGURE 2 ) mostly brown, frontoclypeus with thin dorsal transverse dark brown band, remainder brown with pale transverse arcs, without pale median patch; anteclypeus with median longitudinal light brown line; pronotum stramineous anteriorly, olive green posteromedially; exposed part of mesonotum and scutellum stramineous; thoracic sternites olive green; forewing membrane olive green, veins, stramineous.

Crown distinctly shorter than width between eyes, anterior and posterior margins parallel, evenly rounded in dorsal view. Forewing with second apical cell petiolate.

Male 2S apodemes ( Fig. 2D View FIGURE 2 ) well-developed, parallel to each other, slightly tapered to truncate apices, extended to posterior margin of sternite III, space between apodemes narrowly rectangular; 1S apodeme with trapezoidal dorsomedial extension. Pygofer lobe ( Fig. 2E View FIGURE 2 ) narrowly rounded distally. Subgenital plate ( Fig. 2G View FIGURE 2 ) with lateral margin nearly straight, with 4-6 macrosetae; apex obliquely truncate. Style ( Fig. 2G View FIGURE 2 ) preapical lobe right-angled with four long, fine setae; apophysis very slender and elongate in ventral view, broader in lateral view with 6 short preapical teeth, apex tapered to point. Aedeagus with shaft forming acute angle with dorsal apodeme in lateral view ( Fig. 2I View FIGURE 2 ); shaft strongly tapered from base to midlength in lateral view, distal part of uniform width and slightly sinuate, preapical processes bowed anterad, distal processes extended basad below shaft apex but not distinctly divergent from shaft in ventral view; shaft in ventral view ( Fig. 2H View FIGURE 2 ) parallel-sided through most of length, widened near base, preapical processes slender and extended basolaterad, distal processes shorter and extended ventrolaterad but only reaching distal end of gonopore. Gonopore elongate, approximately three times longer than maximum width, base situated approximately midway between preapical and apical processes.

Etymology. The species name alludes to the similarity of this species to M. facialis Fletcher.
