Figures 1b View FIGURE 1 , 32–34 View FIGURE 32 View FIGURE 33 View FIGURE 34
Material. Holotype female, Shisanya Dong, Jinming, Sanqiao , Daozhen , northern Guizhou, 2022-IV-12, leg. Huanghe Zhou, in SCAU.
Diagnosis. Small-sized for cave trechine, semi-aphaenopsian, wholly pubescent,
Description. Length: 4.5 mm; width: 1.4 mm. Habitus as in Figure 32 View FIGURE 32 .
Body elongate, sparsely and shortly pubescent, propleura and prosternum glabrous, abdominal ventrites and legs covered with dense and long pubescence; whole body brown, but mouthparts, palps, antennomeres and tarsi pale yellow. Microsculptural engraved meshes moderately transverse on head, strongly transverse on pronotum and elytra. Fore body shorter than elytra, (HLm+PnL)/EL = 1.09.
Head much longer than wide, HLm/HW = 2.24, HLl/HW = 1.69, longer than pronotum, HLm/PnL = 1.65, HLl/ PnL = 1.23, narrower than prothorax and pronotum, HW/PrW = 0.84, HW/PnW = 0.88; widest at middle of head from labrum, genae feebly expanded; frons and vertex moderately convex, frontal furrows deep, divergent and reduced posteriad; anterior and posterior frontal setiferous pores located at about middle and basal 1/4 of head; clypeus transverse, 6-setose; labrum transverse, frontal margin shallowly bisinuate, 6-setose; mandibles fairly developed, feebly incurved at apical half, right mandibular tooth tridentate; labial suture completely disappeared; palps slender and subcylindrical, the 3 rd maxillary palpomere slightly shorter (0.91 times) than 4 th, 2 nd labial palpomere slightly longer (1.10 times) than 3 rd; palps glabrous except the 2 nd labial palpomere bisetose on inner margin and with two additional setae on outer margin at middle and subapical part respectively; labial suture disappeared; mentum bisetose, tooth thin, bifid at tip, basal largely foveate; submentum 6-setose; antennae slender, extending at about apical 1/3 of elytra; scape stoutest and shortest, the 5 th longest; the comparative length of each antennomere from the 1 st to 11 th in holotype as: 1 st (1.00) / 2 nd (1.33) / 3 rd (1.76) / 4 th (1.78) / 5 th (1.86) / 6 th (1.76) / 7 th (1.62) / 8 th (1.43) / 9 th (1.43) / 10 th (1.29) / 11 th (1.80).
Prothorax slightly longer than wide, PrL/PrW = 1.12, propleura feebly convex and visible from above, wider than head, almost as wide as pronotum, PrW/PnW = 1.02, widest at about middle. Pronotum longer than wide, PnL/PnW = 1.13, much narrower than elytra, PW/EW = 0.45; disc moderately convex; fore latero-marginal setae at about 1/8 of pronotum from front, hind latero-marginal setae absent; widest at about 1/4 from front; base narrower than front, PWb/PWf = 0.85. Scutellum small.
Elytra elongated, much longer than wide, EL/EW = 1.67; lateral margins subserrate near shoulders, and ciliate throughout; disc moderately convex; striae deep and well-marked; apical striole present; chaetotaxy ( Figure 34 View FIGURE 34 ): similar in Deuveaphaenops (Furongius) gelaophilus Tian & Huang, 2017 ; basal pores present; anterior and posterior setiferous dorsal pores on the 3 rd stria located at about basal 1/5 and a little behind middle of elytra respectively, preapical pore at about apical 1/5 of elytra, closer to suture than to apical margin of elytra; marginal umbilicate pores not aggregated; the 4 th pore widely separated from 3 rd; the anguloapical pore present.
Legs moderately slender; tibiae without longitudinal sulcus; the 1 st tarsomere slightly shorter than, as long as and longer than the 2 nd− 4 th combined in fore, middle and hind legs, respectively.
Male: Unknown.
Remarks. Deuveaphaenops (Furongius) huangheae n. sp. is the second species of the subgenus Furongius Tian & Huang, 2017 ( Huang et al. 2017). It is very similar to Deuveaphaenops (Furongius) gelaophilus Tian & Huang, 2017 , but its head is stouter and a little more expanded, submentum 6-setose, instead of 8-setose in D. (F.) gelaophilus ; strial punctures of elytra well-marked, whereas not clear D. (F.) gelaophilus ; and the 4 th marginal umbilicate pore less backwardly shifted than in D. (F.) gelaophilus ( Figure 33 View FIGURE 33 ).
Etymology. Dedicated to Ms. Huanghe Zhou (a very active member of Guilin Cave Exploration Team, Guilin), who discovered and collected the type specimen.
Distribution. China (northern Guizhou Province) ( Figure 1a View FIGURE 1 ). Known only from the cave Shisanya Dong in Daozhen Xian, Zunyi Shi.
This cave was unexpectedly discovered during construction of tunnels for building a new road in early 2022. It is about 22 kilometres from Xianmi Dong, the locality of D. (F.) gelaophilus , in straight distance. It still has no natural entrance and its length remains unknown, but at least 5 kilometres regarding to the part across two tunnels (Huanghe Zhou, personal communication). There are several chambers and many beautiful stalactites inside the cave. Two beetle individuals were found running on floor in a wet place, about 200 metres from the nearer tunnel. Unfortunately, only one beetle was successfully collected ( Figure 34 View FIGURE 34 ).
