PARATYPES : 2 spec. with the same label data as holotype (1 J SYSU, 1 ♀ PBPC ). Description. Habitus as in Fig.1 . Colour rusty brown, antennae and mouth-parts yellowish; length 2.10–2.15 mm (HT 2.15 mm , n = 3). Fig. 1. Antireicheia chinensis sp. nov. , habitus of male holotype (body length 2.15 mm). Head . Rather broad, neck broad; anterior margin of clypeus between moderately protruding, blunt lateral lobes rather slightly emarginated; impressions of clypeus oblique, broad and deep, longitudinal carina short and thin. Genal posterior angles shortly rounded; moderately vaulted supraantennal plates separated from genae by rather deep and broad furrow; carina of prolonged supraantennal plates blunt. Remnant of eye discernable as small, strongly protruded, unfacetted field in anterolateral margin of long, moderately vaulted genae, surrounded by irregular ring of dark pigment. Vertex distinctly, regularly reticulated. Antennae with antennomere 2 as long as 3 and 4 combined, antennomeres 6–10 moniliform. Figs 2–5. Antireicheia chinensis sp. nov. 2 – aedeagus of holotype in left lateral view; 3 – aedeagus of holotype in ventral view; 4 – urite; 5 – parameres of holotype. Fig. 6. Antireicheia chinensis sp. nov. , stylomeres of paratype. Pronotum. Moderately convex, shiny, reticulation irregular, indistinct; slightly vaulted in lateral view, outline between lateral pores very slightly rounded, not attenuated anteriorly; 0.97–1.01 (HT 1.01) times as long as wide, 1.43–1.44 (HT 1.43) times as wide as head; widest below midlength. Reflexed lateral margin entire, extended from obtuse, not protruded anterior angles to base, distinct in basal part, lateral channel deep below flange. Median line distinctly impressed, disappearing just before basal furrow, anterior transverse impression irregular, just recognisable. Basal part (flange) very small, slightly produced posteriorly. Proepisterna clearly visible from above in apical half. Elytra. Convex, very slightly ovate, in lateral view disc convex, 1.62–1.64 (HT 1.64) times as long as wide, 1.29–1.33 (HT 1.33) times as wide as pronotum, 2.10–2.16 (HT 2.16) times as long as pronotum; humeri slightly protruded, base distinctly sloping; outline regularly broadened on sides, lateral channel very broad, its margin with 3–4 very fine, just recognisable humeral teeth; broadest slightly before midlength; suture broadly depressed at base. Base with very blunt, indistinct tubercle, BSP large. Striae 1–3(4) rather fine on disc, disappearing latero-basally and apically, striae 4(5)–7 consisting of rows of few sparse punctures in about middle third of elytral length. Intervals flat, only first intervals in basal part very slightly vaulted. Third interval with 5–7 and fifth interval with 1–3 very fine DSP. Aedeagus as in Figs 2–3 . Apex of median lobe in lateral view long and slightly narrowed apically, narrowly rounded; in ventral view long and very narrow, as in Fig. 3 . Urite as in Fig. 4 , paramerae bisetose, as in Fig. 5 . Styli as in Fig. 6 . Apical spine very long, evenly curved. Differential diagnosis. Antireicheia chinensis sp. nov. differs from A. margolata , the only known Oriental species of this genus, in having broader head with more distinct microreticulation, pronotum not attenuated anteriorly, and in distinctly narrower elytra with much deeper striae with much coarser punctuation and with DSP also in the fifth interval. Both remaining anophthalmic members of the subtribe Reicheiina from south-eastern Asia belong to different genera. The new species can be easily distinguished from Laoreicheia bulirschi especially by the missing pair of paramedian setae on the disc of pronotum and from Reicheia moritai chiefly by pronotal episterna being invisible from above and by having a very different median lobe of the aedeagus (see Figs 2–5 for A. chinensis sp. nov. and BALKENOHL (2005 : Fig. 5 ) for R. moritai ). Etymology. The name is derived from the name of the country where the species was collected; adjective. Collection circumstances. All specimens were collected by sifting of moist leaf litter in the primary lowland forest (M. Fikáček, pers. comm.). Distribution. China : Guangdong Province .
