Holotype: ♀ deposited in the Chou Io Insect Museum, Ningbo, China with the following labels: ‘Ningbo University (Zhejiang Province), ex Rosa multiflora, (24.III.2026) col. Chuan-Xi Zhang (white label, and host plant in yellow label)’; ‘ Diplolepis ningdaensis Zhang, desig. 1-IV-2026 ’ (red label). Paratypes: 9♀ with the same labels as the holotype.</p><p>Diagnosis. This species is distinguished by the following combination of characters: head and mesosoma uniformly black; antennae black, with scape orange, and pedicel black basally, dark brown apically; metasoma yellowish-brown; hypopygium black ventrally; fore wings hyaline, with infuscation along veins R1, 2r and Rs covering more than half of radial cell; Rs vein curved, radial cell approximately 2.0× longer than broad; head strongly transverse, width 1.6×height in front view; an elevated ridge present between each antennal socket rim and anterior tentorial pit. Although closely related to D. japonica in molecular data, morphology, and host association, the new species is readily distinguished by the following combination of characters: antenna with scape and pedicel yellowish-brown in D. japonica,versus scape orange and pedicel black basally in the new species;infuscation covering less than half of the radial cell in D. japonica (versus covering more than half in the new species); hypopygium entirely reddish-brown or dark brown in D. japonica (versus lower portion black in the new species); mesoscutum with deep median and parapsidal lines in D. japonica (versus median line absent and parapsidal lines obscure in the new species); and host association with galls induced on both R. rugosa and R. multiflora by D. japonica (versus only known from R. multiflora in the new species). The new species is further distinguished from the three species described from Zhejiang and Hunan without known host associations ( D. flaviabdomenis, D. hunanensis, and D. minoriabdomenis; Wang et al. 2013) by the following combination of characters. Compared to D. flaviabdomenis, it differs by the antennae black, with scape orange and pedicel bicolored (versus scape and pedicel brown but flagellomeres darker in D. flaviabdomenis); metasoma yellowish-brown, with hypopygium black on the ventral portion (versus metasoma light yellow, hypopygium yellowish-brown in D. flaviabdomenis); anterior parallel lines very shallow or obscure, extending to 1/9 of the scutum length, median mesoscutal line absent (versus anterior parallel lines very distinct, extending to 1/2 of the scutum length, median line well-impressed in D. flaviabdomenis); and radial cell 2.0× longer than wide (versus 2.8× longer than wide in D. flaviabdomenis). Compared to D. hunanensis, it differs by having 14 antennomeres, with scape orange and pedicel black basally, dark brown apically, and basal half of hypopygium black (versus 12 antennomeres, entirely dark, with scape and pedicel yellowish-brown, and hypopygium light brown in D. hunanensis); F1 nearly 1.5× longer than F2, and terminal flagellomere (F12) 1.5× as long as the subterminal (F11) (versus F1 distinctly shorter than F2, and terminal flagellomere (F10) 3.0× as long as the subterminal (F9) in D. hunanensis); and anterior parallel lines obscure or very shallow, median mesoscutal line absent (versus anterior parallel lines very distinct, median line well-impressed in D. hunanensis). Compared to D. minoriabdomenis, it differs by the antennae black, with scape orange and pedicel black basally, dark brown apically (versus scape, pedicel, and flagellomeres all black in D. minoriabdomenis); hypopygium black on the lower portion (versus yellowish-brown in D. minoriabdomenis); anterior parallel lines obscure or very shallow, extending to 1/9 of the scutum length, parapsidal lines obscure (versus anterior parallel lines distinct, extending to 1/5 of the scutum length, parapsidal lines distinct in D. minoriabdomenis); fore wing radial cell closed (versus open in D. minoriabdomenis); and metasoma normal (versus distinctly small in D. minoriabdomenis).</p><p>Etymology.

In Ningbo, Zhejiang Province, China, most galls on R. multiflora mature and fall to the ground in June to early July, with larvae overwintering inside. After overwintering, the larvae mature (Fig. 19) and pupate within the gall. Adults emerge from the galls during late March to early April (Fig. 14). Each gall produces a single adult gall wasp. Among the 13 individuals observed emerging, all were female; no males were detected. Unmated females deposit eggs directly onto unexpanded young leaflets (Figs 15–17), suggesting the possibility of parthenogenesis. Galls occur primarily on the lower (abaxial) surface of the leaflets, with a few found on the upper (adaxial) surface or on the rachis, and occasionally on the pedicels (Figs 20–26). They are typically green, though some exhibit a rose-red or even red coloration (Figs 21–23, 24), especially on sun-exposed surfaces. Spherical in shape, they bear sparse short spines that are more prominent in young galls (Figs 20–22). Multiple galls may occur densely on a single leaflet. All galls are single-chambered unless invaded by other wasps. When parasitized by the inquiline wasp Periclistus Förster, 1869, galls may become larger due to the presence of multiple Periclistus individuals within a single gall. Mature galls typically measure 5–7 mm in diameter (Fig. 27), with a wall thickness of 2–2.5 mm. The inner cavity is about 3–4 mm in diameter. Although the host plant is a perennial shrub that exhibits vigorous growth during winter and spring, most compound leaves abscise by July. Occasionally, only a few old leaves or remnants consisting of partial leaflets and the rachis remain on the twigs, and some galls persist on these residual leaves and rachises (Figs. 26). Certain galls may even remain until October, but these are often parasitized by other wasps.</p><p>Distribution. China (Zhejiang Province).</p><p>Phylogenetic relationships</p><p>A 658-bp COI sequence of D. ningdaensis sp. nov. was generated (GenBank accession no. PX506479). BLAST comparison revealed 87.7%–95.2% sequence identity with other recognized Diplolepis species. To further assess its phylogenetic position, all publicly available COI sequences longer than 600 bp were retrieved from GenBank and BOLD. A maximum likelihood (ML) tree was subsequently constructed (Fig. 29). The resulting topology strongly supports the placement of the new species within the genus Diplolepis and indicates a close affinity with D. japonica . While D. japonica induces galls on both R. rugosa and R. multiflora (Yasumatsu &amp; Taketani 1967), the new species, D. ningdaensis sp. nov., induces morphologically similar galls on R. multiflora . This indicates that the two species are not only closely related at the molecular level but also exhibit analogous biological traits.</p></div>	https://treatment.plazi.org/id/684FFE31025DFFBEFF360B5911907794	Public Domain	No known copyright restrictions apply.
