6D613513FFC9CB5BFF03FF29FE01BC92.taxon	discussion	Remarks: We have checked 128 specimens of Coccographis nigrorubra collected in Yunnan, and found this species shows very strong sexual dimorphism. The posterior margin of the last abdomen segment is obviously emarginated in the male (Fig. 6 E) but straight in the female (Fig. 6 F); antennal club with four antennomeres in the male (Fig. 6 G), but three in the female (Fig. 6 H); size of the last antennomere in male distinctly smaller than the other three segments; mean body length 13.4 mm (n = 20) and almost same between male (11.3 – 17.7 mm, n = 10) and female (10.5 – 17.3 mm, n = 10). Figure 6 provides the first published photographs of the male (Fig. 6 C) and female (Fig. 6 D) genitalia of the species, and of any member of the Psoinae. It further confirms the very strong sexual dimorphism of this species. Aedeagus of male long, well sclerotized; parameres V shape; penis long, gently tapering apically (Fig. 6 C).	en	Zhang, Yi-Feng, Meng, Ling-Zeng, Beaver, Roger A.

6D613513FFC8CB55FF03F8A3FE15BEF5.taxon	diagnosis	Diagnosis. Currently the subgenus Dinoderastes only includes 4 species (Borowski & Węgrzynowicz 2012). Two of these, D. (Dinoderastes) japonicus Lesne, and D. (D.) scabricauda Lesne have 11 antennomeres. Dinoderus (Dinoderastes) hongheensis sp. nov. Dinoderus (D.) speculifer, Dinoderus (D.) exilis, and D. (D.) nanxiheensis sp. nov. described below, have 10 antennomeres. These four species are distinguished by characters of the pronotum and elytral declivity. The two median teeth on the anterior margin of the pronotum are closely placed in D. exilis, but more widely separated in the other three species. D. speculifer is distinguished by an area on each side of the suture on the elytral declivity which is smooth and shining (Fig. 9 C). D. nanxiheensis has the suture raised on the declivity, and a narrow, impunctate, shining groove on either side of it (Fig. 8 E). The entire elytral declivity is coarsely and densely punctured in D. hongheensis and D. exilis, but the punctures of the former species are much smaller than those of D. exilis, and less closely spaced.	en	Zhang, Yi-Feng, Meng, Ling-Zeng, Beaver, Roger A.

6D613513FFD4CB40FF03FE40FD87BC59.taxon	diagnosis	Diagnosis. The genus Calonistes contains only one species, C. antennalis Lesne 1936, first collected in West Malaysia. The species was later recorded in South Thailand (Beaver et al. 2011). Calonistes vittatus sp. nov. has a relatively larger average body size (3.0 – 3.7 mm vs 2.2 – 3.0 mm for C. antennalis). The apices of the first two club antennomeres in C. vittatus are distinctly emarginate at the insertion of the following antennomere (Fig. 31 C), but the emargination is not distinct in C. antennalis. The elytra are more elongate in C. vittatus (2.2 × longer than wide vs 1.7 × for C. antennalis). The colour pattern of the elytra also differs between the species. In C. vittatus, there is a dorsal median dark band extending from the base of the elytra to the declivity, the sides of the elytra are pale yellowish with only a narrow dark band close to the margin, and not extending to the declivity. In C. antennalis, the dorsal dark band is not distinct except for a narrow dark area near the base, the basal half of the elytra is pale, the posterior half broadly darker, the sides of the elytra have a broad dark band with narrow pale areas at the margin.	en	Zhang, Yi-Feng, Meng, Ling-Zeng, Beaver, Roger A.

6D613513FFD3CB41FF03FAC5FECFB8FD.taxon	diagnosis	Diagnosis. The species is placed provisionally in Calophagus Lesne. The genus at present contains only a single species, C. pekinensis Lesne, 1902 (Liu 2021). This is the only Oriental genus of Xyloperthini which has longitudinal bands of hairs on the club antennomeres, as found in the present species. It shares the thick brush of hairs on the frons, the three rather small tubercles on the margin of the elytra declivity, the presence of pleural pieces in the male, and the general habitus of C. pekinensis. However, in contrast to C. colombiana, C. pekinensis completely lacks a lateral carina on the pronotum, and the female ventrites are unmodified (Liu 2021). C. colombiana also differs from C. pekinensis in the coarse punctation of the posterior part of the elytra, which in C. pekinensis is smooth and very finely punctured. Most genera of Xyloperthini are in need of revision, although some progress has been made (e. g. Liu & Beaver 2017; Liu 2021; Liu et al. 2021), and further studies, preferably comparing DNA, are needed to determine whether the present species is correctly placed.	en	Zhang, Yi-Feng, Meng, Ling-Zeng, Beaver, Roger A.

6D613513FFD2CB42FF03F9E4FF28B9F9.taxon	discussion	Relationships. The lamelliform intercoxal process of the first abdominal ventrite, the mandibles crossed at the tips and the well-developed elongate antennal club show that Gracilenta gen. nov. clearly belongs in the tribe Xyloperthini (Lesne 1901; Fisher 1950). Gracilenta appears most similar to Xylodrypta and Xylodectes among the Xyloperthine genera distributed in the Oriental region. However, it is distinguished from both genera by the large size (10 mm long), very elongate antenna with the last antennomere about 3.5 × as long as wide, and the presence of tufts of hairs on the frons only next to the eyes. It is further distinguished from Xylodrypta by the presence of a false epipleuron near the apex of the elytra, and pleural pieces present in the male.	en	Zhang, Yi-Feng, Meng, Ling-Zeng, Beaver, Roger A.

Length 7.0 – 8.0 mm, 2.6 × longer than wide (n = 3), body cylindrical, elongated, and slightly widened posteriorly. Yellowish brown, head, anterior slope of pronotum and rim of elytral declivity black; anterior part of ventral surface dark, abdomen yellowish. Head. Labrum slightly concave at middle and covered with dense, downward directed, short setae, forming a brush at the anterior margin. Epistoma narrow, surface densely granulate, apical margin arcuately emarginate, sparse soft golden yellow hair directed medially. Fronto-clypeal suture, sulciform, quite distinct. Frons narrow but wider than epistoma, surface densely grainy, convex at middle, with sparse setae clustered in a triangle. Vertex conspicuously wrinkled. Antennae with 10 antennomeres, funicle with 5, club with 3 antennomeres, the first two of club slightly transverse, the third elongate rectangular, slightly contracted near apex, both sides of first two antennomeres of club with distinct areas of sensory pores covered with short, dense, golden yellow hairs. Eyes slightly flattened, without setae behind ocular margins (Fig. 39 B, E). Pronotum. Transverse, 1.25 × wider than long (n = 3), strongly narrowed in front and widest behind middle, surface more or less roughly punctured and covered on, disc and sides glabrous, shining and smooth; lateral carina absent except for a fold near base of pronotum, anterior angles each with a relatively longer, upturned tooth, behind these a row of larger asperities forming the edge of the rasp; asperities on anterior slope large, densely placed, becoming smaller towards summit; area above anterior margin between uncinate teeth with dense, long, white, recumbent pubescence; posterior angles protruding and blunt apically; anterolateral part of pronotum punctured and with sparse, short, white, recumbent pubescence. Scutellar shield. Small, tongue-shaped, dark black, surface finely punctured with sparse short hairs. Elytra. Length to width ratio 1.8 × (n = 3). Glabrous, except at posterior margin, shining, punctures of discal surface fine at base, increasing in density and size posteriorly. Margin of elytral declivity with four pairs of rather bluntly tipped teeth, the more lateral ones curved slightly inwards, the bases broadly widened, the first pair smaller and adjacent to suture, the three outer pairs of similar size, the outermost inserted just below mid-height of declivity. Surface of declivity densely punctured, punctures circular, the base smooth, diameter a little smaller than interspaces. Suture raised in lower two-thirds of declivity, extending to apex. Abdomen. Ventrites covered with dense, fine pubescence. Female. Fourth ventrite with a posteriorly directed median protrusion extended into two long, sharply pointed spines (Fig. 37 D). Male. Last ventrite with pleural pieces. Legs. Anterior tibia normal, widest apically, with a row of small teeth externally, covered with sparse golden yellow hairs. Diagnosis. X. guochuanii is distinguished from the three other species of Xylodrypta by its distinct bi-coloured pattern. Most of the dorsal and lateral parts of the body are yellowish, but the head, the anterior slope of the pronotum and the elytral declivity are dark black. The species also differs from the other three species in the presence of a bispinose process on the fourth ventrite of the female. X. guochuanii is distinguished from X. bostrichoides by the absence of small, densely placed, anteriorly pointed sculpture on the pronotal disc. It resembles X. lanna Liu & Beaver (Liu et al. 2021), and differs from X. bostrychoides and X. zhenghei in having a small tubercle adjacent to the suture on the upper margin of the declivity, in addition to the three larger teeth more laterally. It differs from X. lanna in its colour pattern, weaker punctation of the elytra, and the modification of the fourth ventrite of the female.	en	Zhang, Yi-Feng, Meng, Ling-Zeng, Beaver, Roger A.
