Type material. Holotype male ( NMPC), labeled: “ China, W Hubei 17.VI.2000, Dashennongjia mts. , 31.5N 110.3E, ~ 2400m, Jaroslav Turna leg. // Collection National Museum Prague, Czech Republic // “ HOLOTYPE m#, EURYPOGON , turnai sp. nov., Packova et al. det. 2024 [red label]” GoogleMaps . Paratype male, “ China, W Hubei prov., Dashennongjia Nat. Res., Muyu, E slope, 2000 m, 12–15 Jun 1997, Bolm. lgt.” and the respective red paratype label ( NHMB) .

Diagnosis. This species can be recognized based on the following combination of characters: head, pronotum, and elytra ( Figs 3D View FIGURE 3 , 8C View FIGURE 8 ) more or less uniformly dark brown to blackish; male elytra 1.9–2.1 times as long as wide; elytra ( Fig. 10F View FIGURE 10 ) with relatively smooth surface, elytral punctures fine, small; aedeagus ( Fig. 12F View FIGURE 12 ) without U-shaped phallobase; median lobe slender, distinctly widest basally, gradually narrowed medially, with robust basal struts.

Description. Holotype, male. Body ( Fig. 3D View FIGURE 3 ) 4.70 mm long, 2.55 times as long as wide. Body coloration dark brown to black; labrum, maxillae and labium slightly paler, antennae paler, brown; antennomeres II–III and basal parts of antennomeres IV–XI reddish brown; legs paler reddish brown to brown, ventral lobes on tarsomeres II–IV yellowish brown to reddish brown, apical portion of tarsomere V yellowish to reddish brown. Body dorsally, moderately densely covered with yellowish to light brown pubescence.

Head ( Fig. 8C View FIGURE 8 ) with surface more or less smooth, sparsely covered with usually ovoid punctures, each puncture medially with long, suberect to erected seta mostly oriented frontally, punctures somewhat denser basally. Minimum interocular distance 1.35 times maximum eye width. Labrum transverse, anteriorly widely rounded. Mandible rather gradually narrowed toward apex, moderately curved. Maxillary palpus about twice as long as labial palpus, apical palpomere elongate hatchet-like, widest subapically, apically obliquely rounded and flattened. Antenna ( Fig. 6G View FIGURE 6 ) relatively long, slender, reaching slightly after elytral mid-length, about 0.85 times as long as elytral length; ratio of antennomere lengths = 1.4: 1.0: 1.0: 2.3: 2.9: 2:9: 3.0: 3.0: 3:1: 3.1: 3.8; scape suboval, antennomeres II and III short and simple, subequal in length, together slightly shorter than antennomere IV; antennomeres IV–X elongate, slightly serrate, median antennomeres V–VIII about 3.2–3.5 times as long as wide, apical antennomere simple, apically narrowed.

Pronotum ( Fig. 8C View FIGURE 8 ) transverse, about 1.60 times as wide as long (0.8 mm long, 1.3 mm wide), slightly convex, widest at posterior angles. Anterior margin almost straight, sides bisinuate, posterior margin evenly rounded, slightly emarginate medially; anterior angles almost rectangular; posterior angles projected posterolaterally, short, sharp, apically narrowly rounded; surface of disc uneven, covered with large, shallow round to ovoid punctures, generally sparser medially and denser toward margins, almost contiguous or separated usually up to one third of puncture diameter, interstices between punctures rather smooth, with few small glabrous areas; surface covered with long, suberect to erect setae, denser near margins, especially at posterior corners. Prosternum transverse, before procoxae 3.5 times wider than long, prosternal process relatively short and stout. Scutellar shield slightly wider than long, dorsally slightly convex, apically widely rounded with median portion very slightly produced, covered with thin setae, setae shorter and paler than those on pronotum and elytra.

Elytra ( Fig. 3D View FIGURE 3 ) elongate, 4.7 times as long as pronotum, together 2.1 times as long as wide (3.85 mm long, 1.85 mm wide), subparallel-sided for about 3/4 of their length, then gradually narrowed towards apex, slightly narrower at humeri, widest at about 2/3, apically somewhat truncate; apices conjointly rounded; surface ( Fig. 10F View FIGURE 10 ) rather smooth, moderately densely punctate, punctures arranged in rows, very fine and much deeper than those on pronotum, intervals between punctures within row usually 2.0–4.0 times puncture diameter; intervals between punctures of different rows usually 3.0–4.0 puncture diameter; surface moderately densely covered with relatively long, suberect, yellowish brown to reddish brown setae usually oriented backwards. Leg ( Fig. 3D View FIGURE 3 ) slender, long, femur widest mesally, tibia elongate, longer than femur, apically with pair of thin, sharp spurs, moderately covered with setae; tarsus shorter than tibia; tarsomere I elongate, simple; tarsomeres II–IV gradually shorter, ventrally with elongate lamellae; tarsomere V slender, simple, longest and distinctly narrower than remaining tarsomeres; pretarsal claws wide basally, then abruptly narrowed, slightly curved.

Abdomen with ventrite 1 shorter than remaining ventrites, with distinct intercoxal process, ventrites 2–4 roughly subequal in length, ventrite 5 about 1.5 times as long as ventrite 4, apically widely rounded; each ventrite with circular smooth elevation near lateral edges; surface finely and very sparsely punctate on ventrites 1–4, slightly denser on ventrite 5, with moderately long suberect, yellowish pubescence, slightly longer on ventrite 5. Sternite VIII ( Fig. 11D View FIGURE 11 ) roughly pentagonal, about 1.1 times as long as wide, medially membranous, apically narrowly rounded. Tergite IX ( Fig. 11L View FIGURE 11 ) with base medially roundly emarginate, laterally with short apodemes, apico-medially triangularly and deeply emarginate. Sternite IX ( Fig. 11H View FIGURE 11 ) elongate, subovate, about 2.7 times as long as wide, widest at apical third, base with slender elongate apodemes laterally, apex densely covered with moderately long setae. Tergite X ( Fig. 11L View FIGURE 11 ) about 1.3 times as long as wide, deeply nested in and connected by membrane with tergite IX, apically rounded; surface covered with short setae, mainly subapically and apically.

Aedeagus ( Fig. 12F View FIGURE 12 ) about 3.2 times as long as wide; median lobe about 4.7 times as long as wide, slender, relatively thin, distinctly widest basally, width at base approximately twice width in middle, then gradually narrowed towards middle, then gradually widened towards apex, subapically again gradually slightly narrowed towards apex, apically narrowly rounded; basal struts moderately long, about 1/5 of median lobe length; parameres elongate, apically partly membranous, not reaching apex of median lobe; junction of parameres connected by thin process to transverse basal sclerite which is dorsally attached to basal portions of parameres.

Female and immature stages unknown.

Variability. Body 4.70–5.00 mm long, 2.40–2.55 times as long as wide. Minimum interocular distance 1.35– 1.60 times maximum eye width. Elytra 4.7–4.8 times as long as pronotum, together 1.9–2.1 times as long as wide. Male paratype is slightly paler than the holotype, with elytra dark brown.

Etymology. The species is dedicated to its collector, Mr. Jaroslav Turna (Kostelec na Hané, Czech Republic). The specific epithet is a noun in the genitive singular.

Distribution. Eurypogon turnai sp. nov. is currently known only from the type locality, Shennongjia National Nature Reserve in western Hubei, China ( Fig. 15 View FIGURE 15 ).
