5. Mitjaevia quinquedentata Lin & Zhang View in CoL sp. nov.
( Figs 1q–t View FIGURE 1 , 6 View FIGURE 6 )
Description. Ground color milky. Crown with pair of large black spots in the middle. Eyes gray. Frontoclypeal area yellow with edge blackish, lorum white. Other features as in generic description ( Figs 1q, r, s, t View FIGURE 1 ).
Abdominal apodemes short and broad, extended to middle of sternite III ( Fig. 6b View FIGURE 6 ). Anal tube moderately long, with poorly developed appendage ( Fig. 6a View FIGURE 6 ).
Pygofer side with about 3 stout setae on inner side of posterior margin ( Fig. 6a View FIGURE 6 ), dorsal appendage bifurcated subapically, lower branch finger-like ( Figs 6a, c View FIGURE 6 ), ventral appendage developed, apex pointed and exceeding posterior margin of pygofer lobe ( Fig. 6a View FIGURE 6 ). Subgenital plate expanded subbasally, 2 rows of microsetae along upper margin of subbasal convex part, merging to 1 row near middle, finally extending to constricted region, 3 macrosetae on constricted region near outer margin, several microsetae scattered on caudal part ( Fig. 6a View FIGURE 6 ). Connective Y-shaped, with manubrium moderately developed and central lobe developed ( Fig. 6d View FIGURE 6 ). Apex of style enlarged with inner margin produced ( Figs 6e, f View FIGURE 6 ). Aedeagus with dorsatrium relatively small, preatrium developed, aedeagal shaft tubular and slightly curved ventrad, with 5 small tooth-like processes on ventral surface and one triangular process fused to dorsal surface extended from near base to subapex in profile, gonopore apical ( Figs 6g, h View FIGURE 6 ).
Measurement. Male 2.95–3.05mm, female 2.95–3.05mm.
Material examined. Holotype: ♂, CHINA, Shaanxi Prov., Yanan , 2021.IX ; Paratypes: 2♂ 4♀, same data as holotype .
Diagnosis. This new species is similar to M. wangwushana , but has the aedeagal shaft tubular and with 5 small tooth-like processes on the ventral surface and one triangular process fused to the dorsal surface, and the inner margin of the style apex produced. M. wangwushana has the aedeagal shaft compressed with a pair of large lamellate processes on the ventral surface, and inner margin of the style apex almost truncate.
Etymology. This specific epithet is derived from the Latin word “quinquedentatus”, referring to the 5 small tooth-like processes on the ventral surface of the aedeagal shaft.
