3. Mitjaevia bisecta Lin & Zhang View in CoL sp. nov.
( Figs 1i–l View FIGURE 1 , 4 View FIGURE 4 )
Description. Crown with color from milky to yellow, pair of large black spots in the middle. Eyes with basal part brownish, apical part blackish. Other characters as in generic description ( Figs 1i, j, k, l View FIGURE 1 ).
Abdominal apodemes short and broad, extending to the middle of sternite III ( Fig. 4b View FIGURE 4 ). Anal tube moderately long with poorly developed appendage ( Fig. 4a View FIGURE 4 ).
Pygofer lobe with several microsetae scattered on ventral and caudal parts ( Fig. 4a View FIGURE 4 ), dorsal appendage narrowing from middle to apex, apex pointed ( Figs 4a, c View FIGURE 4 ). Subgenital plate with row of microsetae along outer margin, basal setae longer and forming a group, 3 macrosetae of different lengths near middle ( Fig. 4a View FIGURE 4 ). Connective Y-shaped, with manubrium slim, central lobe developed ( Fig. 4d View FIGURE 4 ). Style with apex slim and foot-like ( Figs 4e, f View FIGURE 4 ). Aedeagus with dorsatrium rudimentary and preatrium developed, aedeagal shaft slightly compressed, gonopore in middle on ventral surface, aedeagal shaft connected with basal process by membranous structure, process bifurcated near middle or subapically, brunches of process continue close to each other ( Figs 4g, h View FIGURE 4 ).
Measurement. Male 2.80mm.
Material examined. Holotype: ♂, CHINA, Sichuan Prov., Mianyang, 2018.Ⅴ.16, Yuru Yang ; Paratypes: 1♂, same data as holotype .
Diagnosis. This new species is similar to M. protuberanta , but has the pygofer dorsal appendage almost straight, the aedeagal shaft without processes subapically, and the pygofer side without a ventral process. M. protuberanta has the pygofer dorsal appendage curved, the aedeagal shaft with pair of tooth-like processes subapically, and the pygofer side with ventral process.
Etymology. This specific epithet is derived from the Latin word “bisectus”, referring to the bisected ventral aedeagal process.
