Salka limboserrata Lin & Zhang sp. nov. ( Figs 1m –p , 6 ) Description. Crown of white, with a large brown patch medially, developed from base to vertex, the patch with branches medially on both sides, extending to eyes, coronal suture only distinct basally. Eyes gray. Face slightly flat in profile. Other features as in generic description ( Figs 1m , n, o, p ). Male 2S abdominal apodemes extending to posterior part of sternite III ( Fig. 6b ). Anal tube short, without appendage ( Fig. 6a ). Pygofer dorsal appendage bifurcated subbasally, branches forming right angle, upper branch with tiny furrows apically; ventral appendage absent ( Figs 6a, c ). Pygofer side with several microsetae scattered on inner side of posterior margin, and group of larger microsetae gathering at cephalo-ventral angle, macrosetae absent; ventral appendage absent ( Fig. 6a ). Subgenital plate expanded subbasally and contracted medially, with 3 macrosetae of different sizes in a row subbasally, row of microsetae along outer margin from subbase to apex, subbasal microsetae larger and forming a group ( Fig. 6a ). Style with apex foot-like with acute heel and slightly longer toe, preapical lobe developed ( Figs 6e, f ). Connective Y-shaped, with manubrium relatively long, median lobe slightly longer than lateral arms ( Fig. 6d ). Aedeagus with large basal process broader and slightly longer than shaft, extended below shaft and curved dorsad subapically, aedeagal shaft slender, tubular, with pair of serrate lateral lamellae subapically ( Figs 6g , h ). Measurement. Male 2.80mm , female 2.80mm . Material examined. Holotype : ♁, CHINA , Hunan Prov. , Chenzhou, 2020.VII, coll. Deliang Xu ; Paratypes : 1♁ 1♀ , same data as holotype . Remarks. This new species is similar to S . singularis , but has the aedeagal shaft slightly inverted S-shaped, with a pair of serrate lamellae subapically, and the ventral process much larger than the shaft in lateral view. Etymology. This specific epithet is derived from the Latin “limbus” (edge) and “serratus” (toothed), referring to the aedeagal shaft processes having serrated margins.
