4. Mitjaevia flexuosa Lin & Zhang sp. nov.

( Figs 1m –p , 5 )

Description. Crown milky to pale yellow, with pair of brown round spots in the middle. Eyes gray marked with brownish. Face milky to yellow. Other features as in generic description ( Figs 1m, n, o, p ).

Abdominal apodemes short and broad, extending to middle of sternite III ( Fig. 5b ). Anal tube short, without appendage ( Fig. 5a ).

Pygofer lobe with few microsetae scattered on caudal part, hind margin rounded ( Fig. 5a ), dorsal appendage sinuate ( Figs 5a, c ). Subgenital plate expanded in the middle, several microsetae on subbasal convex part, 3 macrosetae in the middle ( Fig. 5a ). Connective Y-shaped, with manubrium long, central lobe developed ( Fig. 5d ). Style with apex relatively short and slim ( Figs 5e, f ). Aedeagus with both preatrium and dorsatrium developed, gonopore apical, aedeagal shaft with pair of basal processes on ventral side long and slim ( Figs 5g, h ).

Measurement. Male 1.90–1.95mm.

Material examined. Holotype: ♂, CHINA, Guangxi Prov., Guilin , 2018.VII.16, coll. Shuanghu Lin ; Paratypes: 1♂, same data as holotype .

Diagnosis. This new species is similar to M. elegantula , but has the pygofer lobe posterior margin rounded, the aedeagal shaft basal processes much thinner than the shaft, and the angle between aedeagal shaft and preatrium acute. M. elegantula has the pygofer lobe posterior margin angled, the aedeagal shaft basal processes almost the same width as the shaft, and the angle between aedeagal shaft and preatrium obtuse.

Etymology. This specific epithet is derived from Latin word “flexuosus”, referring to the sinuate pygofer dorsal appendage.
