C04A87D74474883EFF48502F2A315CFC.taxon	materials_examined	Type species: Cynips dugesi variety simulatrix Kinsey 1930: 280, female, gall. Original designation by Kinsey 1930: 277. Current valid name: Atrusca simulatrix (Kinsey, 1930). All species are known from the asexual generation only and associated with white oaks only. Kinsey mentioned that all species induce nearly the same shaped, coloured galls and it is impossible to tell apart species based on galls only. Burks (1979) listed 15 species in the USA.	en	Cuesta-Porta, Victor, Melika, George, Ferrer-Suay, Mar, Vera-Ortiz, Alexis, Pujade-Villar, Juli (2025): Review of the Nearctic and Neotropical genus Atrusca Kinsey, 1930 (Hymenoptera: Cynipidae, Cynipini).

C04A87D74474883EFF48502F2A315CFC.taxon	diagnosis	Diagnosis. Atrusca belongs to a group of Cynipini genera with a straight, complete transscutal articulation; the mesoscutum is never emarginate posterolaterally, not fused with the mesoscutellum. Many species are fully winged, and others are brachypterous. The malar sulcus is always absent, antennae with 12 flagellomeres; the mesoscutum alutaceous to alutaceous-reticulate or delicately coriaceous, with or without piliferous points; in the fore wing the second abscissa of Rs usually strongly curved, the radial cell short, opened, 1.4 – 2.6 × as long as broad, with dark spots and / or dark stripes along veins; the hind tibia without a lobe apically; the ventral spine of the hypopygium with variable length, usually with subapical setae forming a tuft and reaching beyond the apex of the spine, tarsal claws with a basal lobe. Three Nearctic genera, Antron, Atrusca, Cynips (= Besbicus), have a transcutal articulation, toothed tarsal claws, and fore wings with fuscate stripes and / or spots. Atrusca differs from all other mentioned genera by the shape or the radial cell in the fore wing; in Atrusca the second abscissa of Rs is always curved usually strongly curved or angulated distally, then the radial cell short (around 1.6 – 2.4 × as long as broad, rarely slightly longer), while in Antron, Cynips (= Besbicus) the second abscissa of Rs is always straight or only slightly curved, with radial cell longer (around 2.5 – 3.6 × as long as broad, rarely shorter). Also, in Atrusca the mesoscutellum is always elongated, with parallel or subparallel sides, posteriorly rounded or elongated, with shallow invagination posteromedially or gradually narrowed till central part, and the prominent part of the ventral spine of the hypopygium is long or extra-long, needle-like shaped, while in Antron the mesoscutellum as long as broad or slightly longer than broad, posteriorly always rounded and in Cynips (= Besbicus) the ventral spine of the hypopygium has strong lateral lobes in asexual forms or it is triangular in ventral and lateral views, broadest at the base and uniformly tapering to a blunt point at the apex in the sexual generations. Atrusca also differs from Antron and Cynips (= Besbicus) in the morphology of galls; no Antron or Cynips (= Besbicus) species have galls with a fragile wall and with the larval chamber located centrally attached by radiating filaments to the outer wall. Re-description. Asexual female (Figs 1 – 627).

Body length 1.8 – 3.8 mm (including synonyms) (Kinsey 1936). Morphological comments. Kinsey (1936: 93) separates the species (A. pictor, A. pumilio, A. pulex and A. pusa) by small details in the color of the body, the appearance of the fore wing veins and, in the case of A. pumilio, also the presence of piliferous points on the mesoscutum. Studying the large type series deposited in the AMNH, we observed that these characters are variable in each of them, which is why it was proposed (Pujade-Villar et al. 2016) to consider them as a single valid species: A. pictor (= A. pumilio, = A. pulex, = A. pusa). This species, with the proposed synonyms, unlike the other brachypterous species, is characterized by having a complete fore wing venation or reduced veins in the same samplings (not impressed on all length, discontinuous or absent). Looking more carefully we could distinguish three groups of specimens: (i) those with mesoscutum without piliferous points, or very inconspicous (A. pictor, Fig. 376), (ii) those with piliferous points on the mesoscutum and with posterocentrally pointed mesoscutellum (A. pumilio, Figs 403 – 404), and (iii) similar to the previous two but with a posteriorly rounded mesoscutellum (A. pulex, Figs 389 – 390 and A. pusa, Figs 4017 – 418). Examining the material collected by us, we concluded that the tip of the mesoscutellum, due to the rough sculpture, may have distal and central carinae or wrinkles protruded more than the lateral ones and specimens from different localities may or may not have these carinae, so we conclude that the separation of these species based on the presence of those carinae is artificial. On the other hand, it is true that A. pictor has the mesoscutellum without piliferous points or with little obvious piliferous points, but some specimens also have a pointed mesoscutellum as occurs usually in ’ pumilio ’. In addition, some specimens with other morphologies may present visible piliferous points, although they are very scarce, thus we have not yet found morphological differences that can maintain these species as distinct valid ones. New collections and the use of a molecular data might be useful to solve this problem. At the moment we continue to consider the conclusion established in Pujade-Villar et al. (2016) as the correct one. Gall (Figs 381, 395, 409, 423). The gall is similar to all galls of Kinsey’s bella and dugesi complexes, globular.

Atrusca subnigra belongs to the couplet characterized by a dark brown to black body color, with conspicuous black stripes on the mesoscutum, with a complete fore wing venation, the Rs vein of radial cell being strongly curved distally, never almost straight, the rugose or transversally striate pronotum, the entirely rugose mesoscutellum, the mesopleuron sculptured to some degree, with or without piliferous points, the completely smooth speculum, and a ventral spine of the hypopygium setose and relatively short, 2.5 – 4.5 × as long as wide, as in A. deceptrix and A. simulatrix. Atrusca subnigra differs from A. deceptrix and A. simulatrix by having no piliferous points in the mesoscutum especially between the notauli in the posterior half, the slightly posteriorly pointed mesoscutellum, the irregularly rugose mesoscutellar foveae, and the strongly angulate distal part of the Rs vein, while in A. deceptrix and A. simulatrix the mesoscutum is uniformly covered in piliferous points, the mesoscutellum is rounded or with a shallow central invagination on the posterior margin, the mesoscutellar foveae are smooth, and the Rs vein is moderately angulate.

C04A87D744CB888EFF4851762A8B5A1F.taxon	description	Based on a critical re-examination of the diagnostic character states, we re-establish the genus Xanthoteras gen. rev. and transfer back the species X. clavuloides (Kinsey, 1930), comb. rev. while recognizing that the limits of this genus are still uncertain and require revision. Recent phylogenetic studies have shown that the genus Atrusca and X. clavuloides comb. rev. are closely related along with Cynips (= Besbicus), Philonix and some Sphaeroteras (Nicholls et al. 2017, Melika et al. 2021 a, 2021 b, Nieves-Aldrey et al. 2021, Cuesta-Porta et al. 2023). However, the morphology of X. clavuloides comb. rev. does not align with Atrusca given the presence of the malar sulcus. Preliminary molecular analyses (James Nicholls, unpublished data) suggest that X. clavuloides comb. rev. forms a distinct lineage independent from Atrusca and Sphaeroteras. Thus, a detailed revision of all species from Spheroteras and Xanthoteras is necessary to establish the true limits of the two genera.	en	Cuesta-Porta, Victor, Melika, George, Ferrer-Suay, Mar, Vera-Ortiz, Alexis, Pujade-Villar, Juli (2025): Review of the Nearctic and Neotropical genus Atrusca Kinsey, 1930 (Hymenoptera: Cynipidae, Cynipini).
