Biology. According to the original description, this species is a primary parasitoid of the larvae or pupae of Brachartona catoxantha Hampson, 1893 (Lepidoptera: Zygaenidae) in Indonesia. When functioning as a secondary parasitoid, it parasitizes Degeeria albiceps Macquart, 1851 (Diptera: Tachinidae), Bessa remota (Aldrich, 1925) (Diptera: Tachinidae), Apanteles sp. (Hymenoptera: Braconidae), and an Ichneumonidae species. The host of this species in China is unknown.

Remarks. We examined the type specimens through publicly accessible data hosted on the Global Biodiversity Information Facility (GBIF). The forewing of the type specimens has a special-shaped setae (
Figure 3E), and also white bristles of a similar shape on the face (
Figure 3D). Gahan [
25] described these setae as scalelike and mentioned that a similar type of setae is also present in
Tineobius superbus (Dodd, 1917), which is from Townsville, Australia. Upon a careful comparison of Gibson’s description of the head (cf. pp. 284, 288, 291, 327, Figures 41 and 42) [
1] and Fusu and Ribes’s description [
2] of the wings (cf. pp. 8–9), we interpret the term “scalelike” as having the same meaning as “spatulate”. Thus, the known species of
Tineobius in Asia that also have scalelike (spatulate) setae on their forewings include
Tineobius philippinensis (Ferrière, 1938) and
Tineobius indicus (Ferrière, 1938).
Gahan provided a detailed description of the species based on four female specimens. In this study, we identified a male of this species based on COI analysis.

Gaster (
Figure 9A) dark with variably coppery or greenish-bronze metallic luster from different angles, last of gaster with blue metallic luster.
Variation. Female: Obvious color variations (
Figure 10) are observed across the head, pronotum, mesonotum, axillae–scutellum, and propodeum, the coloration varies from bluish-grey to reddish-brown, and sometimes exhibits a green metallic luster. Certain specimens, such as DNA 1102 and 1143, differed by the lack of a distinct white band outside the ovipositor sheath. These variations are observed across the specimens, leading us to consider them as intraspecific rather than interspecific variations. The body length ranges from 3.8 to 5.3 mm, with the ovipositor sheath length ranges from 2.5 to 3.8 mm, larger individuals possess a longer ovipositor sheath. cc: mv: pmv: stv = 3.2–3.8: 1.9–2.7: 1.5–2.4: 1.0, OOL: POL: LOL: MPOD = 1.0: 3.9–4.6: 3.0–3.7: 2.3–3.7. Relative length (and width) of antenna is: scape 76.6–97.1 (13.2–17.3); pedicel 21.1–30.5 (9.8–11.9); and 1st to 8th flagellomeres: 11.1–17.9 (10.0), 30.2–43.8 (8.9–10.9), 29.6–40.2 (9.6–13.4), 27.2–34.3 (11.8–15.4), 23.5–29.0 (12.6–15.9), 21.9–26.1 (12.8–16.7), 17.1–22.3 (14.0–17.7), 13.7–22.9 (14.2–18.5); clava 27.0–46.1 (13.5–25.8). Mesotibia with 9–16 apical pegs in 2 or 3 rows.

Distribution. China (Beijing, Hebei, Henan, Tianjing).
Observation record: China (Jiangsu).
Biology. All specimens from Beijing were collected from trees of
Populus ×
canadensis. The collector observed oviposition behavior of this species in the field and noticed the male in the same tree (
Figure 11). After collecting specimens of wasps, an empty cocoon along with a suspected head capsule of a Lepidoptera insect were discovered behind the bark in the oviposition area. During the period of this wasp generation (June to October), the collector conducted long-term observations at the collection site. Based on the previous research on the host of
Tineobius [
1,
2,
25], we list some of the species he observed around the tree that might be related to this new species: two species of Gelechioidea (Lepidoptera) (
Figure 12),
Eophyllophila sp. and
Dolichopodomintho sp. (Diptera: Tachinidae), and one species of Eurytomidae, one species of Braconidae,
Cheiloneurus sp. (Hymenoptera: Encyrtidae), and
Dirhinus sp. (Hymenoptera: Chalcididae)

Diagnosis. The coloration of this new species resembles that of
Tineobius tamaricis Ribes & Fusu 2017,
Tineobius indicus (Ferrière, 1938) and
Tineobius philippinensis (Ferrière, 1938). The differences between this new species and
Tineobius philippinensis and
Tineobius indicus are shown in our key. Furthermore, it can be distinguished from
Tineobius tamaricis by the following combination of characteristics: (1) The axillae–scutellum of
T. tamaricis is marked with isodiametric reticulate rugose sculpture, whereas in
T. victor, the sculpture is coarsely punctate reticulate (
Figure 8E); (2) The metanotum of
T. tamaricis is convex, while
T. victor is not (
Figure 8G); and (3) In
T. tamaricis, the setae in the basal cell region of the forewing are pale, contrasting with the brown setae in other areas, whereas in
T. victor, the setae on the forewings are uniformly brown (
Figure 8H).
Remarks. In addition to the existing specimen sources, we received a photograph (
Figure 13) from Nanjing, Jiangsu province, which is highly likely to depict this new species. We speculate that this species has a broader distribution in China and is likely widespread across the North China Plain, north of the Yangtze River.
