Name

Amamiclytus wuxingensis Yang & Wang, 2019 sp. nov.Wikispecies linkZooBank linkPensoft Profile

Type locality

Wuxing Village, Leishan County, Guizhou Province, China. 26°21.36'N, 108°01.82'E, altitude ca 1190 m.

Type series

Holotype male, glued on paper card, with genitalia in a separate microvial. Original label: “中国贵州省雷山县五星村/蔷薇科稠李属植物/东经:108°01.82',北纬:26°21.36' / 2019年4月6日/杨书林采” [Wuxing Village, Leishan County, Guizhou Province, China / flowering bird cherry (Prunus sp.) / 26°21.36'N, 108°01.82'E. / 6 April 2019 / Shulin Yang leg.] (GZNULS). HOLOTYPE / Amamiclytus / wuxingensis / Shulin Yang [red handwritten label]. Paratype 2 males, same data as holotype.

Differential diagnosis

Amamiclytus wuxingensis sp. nov. should be grouped into Group III proposed by Niisato and Han (2011)[1] along with Amamiclytus juni Niisato & Han, 2011, Amamiclytus yulongi Niisato & Han, 2011 and A. limaticollis. They share common body and genitalia characters; short, broadened and matted body, rather transverse pronotum with distinctly arcuate sides, without white pubescence near the basal margin, median struts about half the length of median lobe, and parameres about 2/5 the length of tegmen.
Amamiclytus wuxingensis sp. nov. can be distinguished from most of its congeners, including A. yulongi and A. limaticollis of the same group, by the La extending forward and reaching to S. The La does not extend toward and reach S in most of the other congeners.
Amamiclytus juni and Amamiclytus mimicus Holzschuh, 2018 also have La extending towards and reaching S as in A. wuxingensis sp. nov. A. wuxingensis sp. nov. differs from A. juni in the a) La is distinctly rounded arcuate while less rounded and obliquely turning from the middle of the elytron towards S in A. juni; b) Lp transverse while slightly arcuate in A. juni; c) Ps absent while present in A. juni; d) Mss sparse while completely absent in A. juni. Furthermore, characters of male genitalia, e.g., the widened part at the base of the parameres and the pointed apex of the dorsal plate of the median lobe, can be used to differentiate A. wuxingensis sp. nov. from A. juni. Tergite eight is as wide as sternite eight and its apex is concave at the middle in A. wuxingensis sp. nov. Tergite eight is much wider than sternite eight and its apex is truncate in A. juni.
Amamiclytus wuxingensis sp. nov. can be distinguished from A. mimicus by the absence of the white band on the pronotal base and the presence of a white band on the elytral apex. On the other hand, A. mimicus has a white band at the pronotal base but no white band on the elytral apex. The white spot behind the suture is short and the white band before the middle of elytra is distinctly arcuate in A. wuxingensis sp. nov., while they are long and obliquely transverse, respectively, in A. mimicus.

Description

Male. Body (Fig. 1), length: 3.5–5.0 mm (N = 3). Black, glossy in general, dark brown in mouthparts, antenna, abdomen and legs. Body sparsely clothed with long pale hairs, which are darker on disc of pronotum. Maculations: Pb absent though sparsely covered with white hairs on basal third of pronotum; B absent; S on basal 1/8, longitudinally, short; La on basal 2/5 of elytron, obliquely arcuate and reaching S; Lp on apical third of elytron, transverse, slightly oblique, complete and reaching suture; A distinct, slightly wider than Lp; Msl distinct; Mss sparse; Mta distinct, dense on apical third of metepisternum and along posterior margin of metasternum and on hind coxae; V1 distinct, dense on sides of posterior margin of ventrite; V2 nearly absent, only sparsely with white hairs; V3 and V4 absent. Head: Frons nearly square, longer than wide, narrowest at the middle of lower eye lobes, clothed with sparse and long hairs with a pattern extending outwards from center of frons; clypeus slightly convex; vertex gradually raised towards antennal insertions; occiput convex with dense large punctures and clothed with sparse short pale hairs; antennae thin and relatively short, reaching 2/5 of elytral apex, clothed with long pale hairs on scape and mostly short but denser pale hairs on other antennomeres, long spinous hairs at internal apices of antennomeres 3, 4 and 5; antennomere 3 distinctly longer than scape and antennomere 4. Thorax: Pronotum slightly longer than wide, constricted abruptly at base; disc slightly raised and convex, matted with sparse granules; scutellum long triangular, slightly acute at apex; prosternum with sparse white hairs covering most of prosternum except the frontal margin of prosternum and the prosternal process. Elytra: nearly parallel-sided, rounded at humeri, obliquely truncated at apex; disc almost evenly convex except depressed parts at basal fifth near humeri; sparsely fine punctured. Legs relatively short and slender, with hind femora gradually swollen apically, exceeding elytral apices at apical sixth. Abdomen sparsely fine punctured, with sparse long pale hairs. Male genitalia (Fig. 2): Median lobe slightly arcuate in lateral view. Dorsal plate slightly narrower than ventral plate in apical fourth, narrowed down to a point at apex. Ventral plate also narrowed to a sharp point at apex. Median struts about half the length of median lobe, widest at base, constricted to basal fifth, nearly parallel for remainder. Tegmen elongate, slightly shorter than median lobe; parameres about 2/5 the length of tegmen, each paramere nearly parallel-sided, slightly narrowed in external side in apical fifth, rounded at apex, provided with numerous short setae and a few relatively long setae at apex; basal ridge slightly raised. Tergite eight elongate and quadrate, slightly narrowed towards apex, which is rounded at sides and concave at the middle, with short to long sparse setae. Sternite eight as wide as tergite eight, concave at the middle as tergite eight, apical margin bi-arcuately rounded, and provided with sparse short to long setae.

Etymology

The name of the new species, wuxingensis, refers to the type locality, Wuxing Village, Guizhou Province, China.

Note

Niisato and Han (2013)[2] discussed the wide gap in the distribution of Amamiclytus in South China and Southwest China and they expected to discover further members of Amamiclytus in these areas. The locality of A. wuxingensis sp. nov. falls in this wide distribution gap. Description of A. wuxingensis confirms and continues the expectation of discovering more members of Amamiclytus in these areas.
