This is an open access article distributed under terms of the Creative Commons Attribution License (Attribution 4.0 International - CC BY 4.0). The genus Neocerambyx J. Thomson, 1861 has been studied and discussed quite frequently in the last years (Lazarev 2019, 2020; Miroshnikov 2020a, b, 2021b, 2022), with several new species being described (Holzschuh 2020; Jac- quot 2020; Li et al. 2020; Miroshnikov 2021a). It currently includes 24 valid spe- cies and two subspecies (Tavakilian and Chevillotte 2024). The genus can be divided into six species groups (Miroshnikov 2020b): 1. The paris group (7 described and 1 new species): N. paris (Wiedemann, 1821), N. gigas (J. Thomson, 1878), N. grandis Gahan, 1891, N. luzonicus Hiuidepohl, 1987, N. opulentus Holzschuh, 1998, N. katarinae Holzschuh, 2009, N. paulae Miroshnikov, 2021a, and N. liyuani sp. nov. 2. The unicolor group (6 described and 2 new species): N. unicolor (Gahan, 1906), N. vitalisi Pic, 1923, N. elenae Lazarev, 2019, N. brudermanni Holz- schuh, 2020, N. punctulifer Holzschuh, 2020, N. sabinae Holzschuh, 2020, N. miaobenfui sp. nov., and N. gui sp. nov. 3. The pellitus group (6 described species): N. pellitus (Hitzinger, 1943), N. the- resae (Pic, 1946), N. rugicollis Gressitt, 1948, N. bakboensis Miroshnikov, 2018, N. zubrzyckii Miroshnikov, 2021a, and N. melas (Holzschuh, 2021). 45 Mei-Ying Lin et al.: Three new species of Neocerambyx from China 4. The dierli group (3 described species): N. dierli (Heyrovsky, 1976), N. atrat- ulus (Holzschuh, 2018), and N. gracilipes Jacquot, 2020. 5. The pubescens group: N. pubescens Fisher, 1936. 6. The raddei group: N. radddei Blessig, 1872. Eleven species / subspecies of Neocerambyx have been recorded from Chi- na (Chen et al. 2019; Lazarev 2019; Jacquot 2020; Li et al. 2020; Miroshnikov 2020a). In the present paper, three new species are described from China and one species is newly recorded from China, which raises the species number to 15. Materials and methods Habitus images of Neocerambyx liyuani sp. nov., N. gigas and N. miaobenfui sp. nov. were taken using a Canon 50D DSLR with a Canon EF 100 mm f/2.8L IS USM lens, and a dual LED fill light was used as the light source. Images of the same object at different focal planes were combined using Zerene Stacker v. 1.04 stacking software. Other habitus photographs were taken with a Canon EOS 7D camera with a Canon Macro 100 mm lens. Images of the same object at different focal planes were combined using Helicon Focus v. 8 stacking soft- ware. Adobe Photoshop CS6 was used for postprocessing.

Diagnosis. This new species is rather peculiar by the shining pubescence and particularly the male somewhat resembles a miniature Neocerambyx gigas (Fig. 3A—D), but differs from that species by the presence of a short transverse groove between upper eye lobes; the smaller body size (N. gigas measures 55- 84 mm in length); the features of the sculpture of the pronotal disc; the more slender elytra of both sexes (cf. Figs 1A and 3A); the longer female antennae (cf. Figs 1C and 3C), and the shape of the external apical angle of female an- tennomeres 8-10 and of the apex of female last antennomere (in N. gigas, the external apical angle of female antennomeres 8-10 is very sharp and the distal part of female last antennomere sharply tapers towards the apex). The new species should be attributed to the paris group sensu Miroshnikov (2020b): the anterior coxal cavities externally with a large triangular protrusion, the external apical angle of antennomeres 5-10 without a sharp spine, the ely- tra with a recumbent setation forming an iridescent pattern. Description. Body length 43.0-47.0 mm, humeral width 12.0-12.5 mm. Body black to black-brown, covered with a golden yellow shining pubescence. Head with pubescence especially dense around compound eyes. All antennomeres black-brown, without annulations, covered with golden yellow pubescence, without a fringe of setae underneath. Male antennae ex- ceed apex of elytra by approximately the middle of antennomere 8; scape stout, subequal to third antennomere in length; third to fifth antennomeres distinctly ZooKeys 1247: 45-61 (2025), DOI: 10.3897/zookeys.1247.153858 47 Mei-Ying Lin et al.: Three new species of Neocerambyx from China C Figure 1.

Diagnosis. This new species, in combination with the structure of male anten- nomeres 3 and 4, the sculpture of the pronotal disc, and the setation of the elytra, somewhat resembles Neocerambyx sabinae, but differs by the less strongly pro- truding external apical angle of antennomere 1, the scutellum being more sharply narrowed towards the apex, the silver-grey recumbent setation of the antennae and legs, poorly hiding a black or dark coloration of the cuticle (in N. sabinae, the recum- bent setation of the antennae and legs is of yellow tones and strongly or signifi- cantly hiding the black or dark coloration of the cuticle), the less strongly developed antennal tubercles, the shorter male antennae (and thus less elongate antennom- eres), and the smaller body size (N. sabinae measures 73-79 mm in length). Neocerambyx miaobenfui sp. nov. can also be compared to N. unicolor (Ga- han, 1906), N. vitalisi Pic, 1923, N. punctulifer Holzschuh, 2020, and N. bruder- manni Holzschuh, 2020. Like in N. sabinae, it can be distinguished by the less strongly protruding external apical angle of antennomere 1 and the shorter male antennae (and thus less elongate antennomeres, including 3-5). In addition, N. miaobenfui differs from N. unicolor and N. vitalisi by the more strongly inflated apical part of male antennomere 4, and from N. punctulifer and N. brudermanni by the more strongly inflated apical parts of male antennomeres 3 and 4. The new species should be attributed to the unicolor group sensu Mirosh- nikov (2020b), which includes all the species discussed above. The anterior coxal cavities are externally with a large triangular protrusion and the external apical angle of antennomeres 5-10 is without a sharp spine, which is the same as the paris group, but “elytra with a uniform recumbent setation that does not form an iridescent pattern” (Miroshnikov 2020b). Description. Body length 47.5-64.0 mm, humeral width 14.0-18.0 mm. Body black to black-brown or dark brown, covered with orange yellow to ochraceous pubescence. Head with pubescence, especially denser around eyes. Most of antennomeres black starting from scape, last few antennomeres somewhat lightened, all antennomeres without annulations, covered with ochraceous or yellow pubescence, without a fringe of setae underneath. Male antennae exceed apex of elytra by antennomere 9; scape stout, barely short- er than third antennomere; third and fourth antennomeres (third in particular) strongly and asymmetrically inflated in apical part, without irregular rugose sculpture; fifth distinctly more slender than fourth but stouter than sixth, and distinctly longer than fourth whereas shorter than sixth; sixth to eleventh an- tennomeres become gradually more slender and flatter, seventh longer than sixth, shorter than fourth and fifth combined; eighth and ninth antennomeres subequal in length, eleventh is the longest, much longer than tenth. Female an- tennae slightly fail to reach the apex of elytra; scape stout, subequal to fourth antennomere in length; third to fifth antennomeres slightly expanded apical- ly, third and fifth subequal and both longer than fourth; sixth to eleventh an- tennomeres become gradually more slender and flatter, sixth distinctly longer than fifth, distinctly shorter than fourth and fifth combined, seventh subequal ZooKeys 1247: 45-61 (2025), DOI: 10.3897/zookeys.1247.153858 52 Mei-Ying Lin et al.: Three new species of Neocerambyx from China Figure 4.

Eye deeply emarginate, lower lobe very large; head with a short longitudinal groove between upper eye lobes and on occiput. Mandible moderately sized, curved and sharp apically, with two mesal teeth. Prothorax covered with dense orange yellow or ochraceous pubescence, fringed with short ochraceous setae at anterior margin of pronotum and a few long, erect setae scattered on sides. Pronotum 1.29 or 1.28x as wide as long in male and female, respectively; at base slightly wider than at apex; usually with an abrupt constriction at apex and a moderate constriction at base; pronotum with coarse, irregular (in some regions largely transverse) grooves, usually ~10 in number. Scutellum covered with ochraceous pubescence, posterior angle roundly trian- gular. Elytra moderately elongate, 2.70-2.82x as long as humeral width; approx- imately parallel-sided from base, apex rounded, apical external angle obtuse, su- tural angle with a short tooth. Venter with most sclerites pubescent. Prosternal intercoxal process with a pair of blunt tubercles (more distinct in males), expand- ed posteriorly; mesoventral intercoxal process entirely covered with pubescence, emarginate and forming two lobes apically, between coxae distinctly wider than prosternal process; metasternum with a very thin median groove. Legs black, partly black-brown, moderately long; femora quite robust, tibiae and tarsi slender; metafe- mur reaching middle of third visible abdominal sternite; metatarsomere 1 shorter than tarsomeres 2 and 3 combined. Both sexes with last visible abdominal sternite at apex with a shallow emargination; last visible tergite emarginate apically. Etymology.

Diagnosis. The new species is especially similar to Neocerambyx punctulifer Holzschuh, 2020, but differs by the sculpture of the pronotal disc, namely, the more strongly expressed median groove, two oblique incomplete grooves on either side, and the sparser and longer transverse folds and grooves; it further differs by the less elongate male antennomeres starting from antennomere 3, the shorter female antennae (in N. punctulifer, female antennae distinctly sur- pass apex of elytra), and the presence of the rough longitudinal folds on male scape at least dorsally. Compared with N. brudermanni Holzschuh, 2020, the new species differs by the well-expressed median groove and the clearer and ZooKeys 1247: 45-61 (2025), DOI: 10.3897/zookeys.1247.153858 54 Mei-Ying Lin et al.: Three new species of Neocerambyx from China h D Figure 5.
