The original description of Domene reitteri is based on an unspecified number of syntypes from "Tienmuschan (nordwestliches [sic] China) ex coll. E. Reitter" ( Koch 1939 ). Five syntypes, one male, three females and one unsexed specimen, were located in the Koch collection at the Naturhistorisches Museum Basel. The male syntype is designated as the lectotype.

Habitus as in Figs 7A, 8A, 8D. Body blackish brown; legs with dark brown profemora and protibiae, basal halves of metafemora light brown, distal halves gradually infuscate; antennae brown to light brown. Figure 7.

Scales: A, D 1.0 mm; B-C 0.5 mm. Head orbicular, broadest across eyes; punctation (Fig. 9A) moderately coarse, weakly umbilicate, and very dense, interstices forming very narrow ridges. All antennomeres longer than broad; antennomeres IV-X of equal length; antennomere I 1.6 times, II 1.1 times, III 1.3 times, XI 1.3 times as long as IV. Maxillary palpus very slender, preapical joint 2.7-3.2 times as long as broad. Figure 9. Domene reitteri . A median dorsal portion of head B median portion of pronotum C female tergite VIII D female sternite VIII E female tergites IX-X . F male sternite VII G male sternite VIII H aedeagus in ventral view I aedeagus in lateral view J aedeagus in dorsal view. Scales: A-B 0.2 mm; C-J 0.5 mm. Pronotum slightly narrower than head, widest in the middle; lateral margins convex in dorsal view; punctation (Fig. 9B) somewhat coarser than that of head; midline with rudiment of a fine glossy line. Elytra without distinct longitudinal ridges; suture weakly elevated; punctation very fine, dense and uniform; hind wings reduced. Protarsomeres I-IV dilated in both sexes. Abdomen with punctation fine and dense on tergites III-VI , finer and somewhat sparser on tergite VIII, posterior margin of tergite VIII weakly convex in the middle (Fig. 9C); interstices with shallow microreticulation; posterior margin of tergite VII with palisade fringe. Male. Sternites III-VI unmodified; sternite VII (Figs 8B, 9F) distinctly transverse, with median impression of triangular shape posteriorly, this impression with numerous distinctly modified, short and stout black setae; posterior margin distinctly concave in the middle; sternite VIII (Figs 8B, 9G) transverse, with pronounced and symmetric impression posteriorly, this impression with distinctly modified short and stout black setae, posterior excision small and U-shaped; aedeagus as in Figs 8C, 9 H-J , ventral process stout and apically acute; dorsal fig with large and lamellate apical portion, and with short, thin basal portion; internal sac with membranous structures. Female. Posterior margin of sternite VIII (Fig. 9D) broadly convex; genital segments with weakly asymmetric large and moderately sclerotized structure (Fig. 9E). Comparative notes. The fine, dense and uniform punctation of the elytra, and the similar shape and chaetotaxy of the male sternite VII and sternite VIII suggest that Domene reitteri is most closely allied to Domene chenae . It is distinguished from Domene chenae by the finer punctation of the head and pronotum, the numerous distinctly modified, short and stout black setae on the male sternite VII, the stouter ventral process of the aedeagus and by the shape of the sclerotized structure in the female genital segments. Distribution and natural history. The distribution is confined to several localities in the Tianmu Shan range in the northwest of Zhejiang. The specimens were sifted from leaf litter in broad-leaved and primary mixed forests at altitudes of 300-1500 m.
