Agrilus planipennis Fairmaire.

Oobius agrili is a solitary thelytokous egg parasitoid of A. planipennis, discovered in 2004 during foreign exploration for natural enemies in northeast China (Zhang et al. 2005; Liu et al. 2007; Trjapitzin and Volkovitsh 2011). Adults O. agrili were reared from eggs at the USDA Forest Service Northern Research Station laboratory in East Lansing, Michigan, USA. Rearing stock for this colony originated from parasitized A. planipennis eggs collected from Fraxinus pennsylvanica trees in Jingyuetan Forest Park, Changchun, Jilin Province, China in 2004–2009. In 2007, O. agrili introductions began in Michigan, USA, for classical biological control of A. planipennis. As of fall 2014, releases of O. agrili had expanded to 19 states (Bauer et al. in press). Abell et al. (2014) reported parasitism of A. planipennis eggs averaged approximately 20% in 2012–2013 at some sites where O. agrili was established, however, more studies are needed to assess the impact of O. agrili and other A. planipennis biocontrol agents on ash recovery in the USA. Since 2010, stock cultures of O. agrili have been provided to the USDA Animal and Plant Health Inspection Service Emerald Ash Borer Biocontrol Facility, Brighton, Michigan, USA, for mass-rearing and releasing as a biocontrol agent of A. planipennis in infested regions of the USA (Mapbiocontrol 2014). To distinguish O. agrili from the known native and the other introduced Oobius species, we provide illustrations of its metatarsus (Fig. 1), female antenna (Fig. 2), lateral habitus of the female (Fig. 3), and base of the forewing (Fig. 4).

USA (Illinois) (Girault 1916).

Megacyllene robiniae (Forster) (Cerambycidae) (Girault 1916 [as Cyllene robiniæ]).

The identity of this species remains unclear because the original description is poor and without any illustrations; unfortunately, the slide with a head and a forewing of each sex (Girault 1916) could not be found in the USNM and is presumed lost. The lectotype label affixed by B. D. Burks was not validly designated and is merely a paralectotype. To facilitate identification of this species, we provide illustrations of its scutellum (Fig. 17) and habitus of the female in dorsal view (Fig. 18).

FEMALE (holotype). Body dark brown to black except scutellum and propodeum brown; scape and pedicel brown, flagellum light brown; legs whitish or pale yellowish with wide brown bands on coxae, femora, and tibiae.

Frontovertex and mesonotum with faint mesh-like or lineolate sculpture [very difficult to see in dry-mounted specimens, best observed in slide-mounted ones (as in Fig. 25)]. Pronotum, mesoscutum, axillae, and scutellum with short, dusky setae; scutellum also with a pair of long, fine setae near posterior margin.

Head (as in Fig. 15, collapsed when air-dried) with ocelli in an obtuse triangle, posterior ocellus a little less than its diameter away from eye margin. Transfacial and inner orbital sutures present. Mandible 3-dentate, the inner tooth with two denticles; maxillary palpus 4-segmented, labial palpus 1-segmented (i.e., palpal formula 4–1).

Antenna (Fig. 12) inserted below lower eye margin. Radicle about 0.3× total scape length, rest of scape slender, 4.5× as long as wide, a little wider in the middle, with faint longitudinal sculpture. Pedicel longer than any funicle segment; F1–F5 slightly transverse, F1–F4 subequal in length, F5 a little longer and slightly wider than long; F6 the longest funicle segment, longer than wide; F1–F5 without mps, and F6 with 2 mps. Clava 3-segmented, about 2.3× as long as wide and almost as long as funicle; first claval segment with 1 mps, second and third segments each with 3 mps.

Mesosoma a little shorter than gaster (Fig. 13). Mesoscutum about 1.7× as wide as long. Scutellum a little wider than long, a little shorter than mesoscutum; scutellar placoid sensilla closer to the posterior margin of scutellum and close to each other.

Wings (Fig. 31) not abbreviated, forewing extending far beyond apex of gaster. Forewing 2.1× as long as wide, hyaline; marginal setae very short; disc densely setose, linea calva interrupted posteriorly by an irregular row of setae, filum spinosum present. Hindwing 4.2× as long as wide, hyaline; longest marginal seta 0.3× maximum wing width.

Mesotibial spur a little longer than mesobasitarsus.

Ovipositor occupying a little more than 0.5× length of gaster, exserted markedly beyond gastral apex (by 0.2× own length) (Fig. 13); ovipositor length:metatibia length ratio 1.2:1. Outer plate of ovipositor with two subapical setae.

Measurements of the holotype (mm, as length or length:width). Body (of the dry-mounted specimen prior to slide-mounting): 0.462; mesosoma: 0.233; gaster: 0.245; ovipositor: 0.173. Antenna: radicle: 0.03; rest of scape: 0.103; pedicel: 0.045; F1: 0.012; F2: 0.012; F3: 0.011 (0.012); F4: 0.012; F5: 0.015; F6: 0.03; clava: 0.103. Forewing: 0.495:0.234; longest marginal seta: 0.021; hindwing: 0.357:0.085; longest marginal seta: 0.025.

Variation (paratypes). Body length 0.43–0.46 mm (dry-mounted specimens from A. subcinctus, Fig. 33) or 0.46–0.53 mm (critical-point dried specimens from A. egenus, Fig. 34). In the latter specimens, legs (except tarsi) are somewhat darker (mostly brown), scape (minus radicle) of the female antenna is about 5.0× as long as wide, and clava is about 2.5× as long as wide. Mandibles are identical for specimens reared from both host species, and there is no doubt that they are conspecific. In all specimens, F6 is sometimes slightly paler than other flagellomeres but not contrastingly, still almost concolorous or often concolorous.

MALE (paratype from A. subcinctus). Head dark brown, mesosoma and gaster dark brown to black except mesoscutum with a brownish tinge, base of gaster whitish; antenna with scape and pedicel brown to dark brown, flagellum light brown. Antenna (Fig. 16) with scape minus radicle 2.9× as long as wide; F2–F4 more or less subequal in length, F1 and F5 slightly longer, F6 the longest funicle segment; F2–F4 without mps, F1, F5, F6 and clava with mps; flagellar segments with very long setae (slightly longer than each funicle segment’s width); clava entire, 2.6× as long as wide, a little wider than funicle segments. Mesosoma (Fig. 25) about as long as gaster. Forewing 2.0× as long as wide, hyaline. Genitalia (Fig. 14) typical for the genus.

Variation (paratypes from A. egenus). Body length 0.4–0.5 mm (critical-point dried specimens).

This species is similar to the European O. zahaikevitshi Trjapitzin (Figs 19, 30), whose type locality is Zhuravlivka, Vinnytsia Oblast, Ukraine, where it was reared from eggs of Agrilus viridis (Linnaeus) on Carpinus betulus (Trjapitzin 1963). Oobius zahaikevitshi was recently well illustrated by Gumovsky et al. (2013). It was recorded from several European countries and Agrilus spp. hosts, listed by Trjapitzin and Volkovitsh (2011) and Noyes (2014). However, we are not absolutely confident that all these records are correct: it is quite possible that they might represent a complex of more than one cryptic species that are difficult to distinguish without supporting molecular data and thorough morphological studies based on good quality slide-mounted specimens. Proportions of funicle segments of the female antenna seem to be somewhat different between the specimens of O. zahaikevitshi from Ukraine illustrated by Trjapitzin (1963) and Gumovsky et al. (2013), in which F5 is about as long as wide, and the examined specimens from Volgograd Province of Russia, in which F5 is a little wider than long (Fig. 30).

Oobius minusculus differs from O. zahaikevitshi in having the palpal formula 4–1, a relatively smaller F5 of the female antenna and also by F6 being longer than wide and almost concolorous or often concolorous with other flagellomeres (Fig. 12). In contrast, the palpal formula for O. zahaikevitshi is 3–1, F5 is relatively larger, and F6 is about as long as wide and contrastingly lighter than other flagellomeres (Fig. 30), as also described and illustrated in Trjapitzin (1963) and Gumovsky et al. (2013).

Oobius minusculus is the only described native Nearctic species of Oobius s. str., as characterised by Noyes (2010) in having the outer plate of the ovipositor being relatively short and apically rounded with paired subapical setae (one long and one short), in which this new taxon fits well. In the key by Trjapitzin and Volkovitsh (2011) to the world species of Oobius (s. str.), it keys to O. zahaikevitshi. In Noyes (2010), O. minusculus tentatively keys (although it really does not key to any of the included Neotropical species) to the same couplet with O. xochipili Noyes and O. zagan Noyes from Costa Rica, from both of which it differs by F5 of the female antenna being much less transverse, just slightly wider than long (Fig. 12) whereas in O. xochipili and O. zagan F5 is anelliform, much wider than long (Noyes 2010).

The name of this new taxon is an adjective referring to its small size.

Agrilus subcinctus on ash (Fraxinus spp.) and A. egenus on black locust (Robinia pseudoacacia).

Originally reported by Petrice et al. (2009) as Avetianella sp. that parasitized A. subcinctus eggs. The second author has never found this parasitoid to overwinter in A. subcinctus eggs. However, collections of A. egenus eggs found overwintering O. minusculus larvae in eggs. This species likely attacks other Agrilus spp. in North America, and has multiple generations per year.

The following specimens of O. zahaikevitshi were examined: Bulgaria, Plovdiv Prov., Klisura, 27.vi–8.vii.1975, A. Atanasov, from eggs of Agrilus cuprescens (Ménétriés) on Rosa sp. [1 ♂, BMNH] (det.

Among the Nearctic species of Oobius, O. whiteorum is most similar to O. dahlsteni, from which it differs by the proportions of the funicle segments of the female antenna, as indicated in the key. In Trjapitzin’s (2001) key to the world species of the former genus Avetianella (s. str.) in which this new species mostly fits, as characterised by Noyes (2010) in having the outer plate of the ovipositor being conspicuously distally elongate and ribbon-like and always with only a single subapical seta, it keys to O. dahlsteni. Oobius whiteorum differs from O. depressus, to which it is also somewhat similar, by a relatively less flattened body and by the much smaller body size in females; according to Girault (1916), the body length of the latter species is 1.15 mm. Oobius whiteorum differs from the North American species, but Neotropical species O. hasmik (Trjapitzin), known from Mexico (Trjapitzin 2001) and also Costa Rica (Noyes 2010), by the “closed” linea calva (Fig. 27) on the forewing (“open”, not interrupted, in O. hasmik, Fig. 21) and also by the different proportions of the scape of the female antenna (Figs 26 and 20, respectively). In Noyes (2010), O. whiteorum keys to the same couplet with O. lutron Noyes from Costa Rica and Brazil, from which it differs by each of F4–F6 of the female antenna being of different length and longer than wide (Fig. 26) whereas in O. lutron F4–F6 are subequal and each quadrate or hardly longer than broad (Noyes 2010).

Agrilus anxius Gory on European white birch (Betula pendula).

This species is named in honor of Lisa and Michael White of Chicago, Illinois, USA, good friends of the author’s family.

According to Loerch and Cameron (1983), additional voucher specimens of the egg parasitoids of A. anxius were deposited by them in PSUC; any of them belonging to this species are non-type specimens. Unfortunately, due to a renovation of the museum, point-mounted specimens in that collection are now inaccessible (A. Deans, personal communication).

The following paratypes [UCRC] of O. hasmik were examined, all collected at Las Barracas (~30 km E of Santiago, 23°28'02"N, 109°27'01"W, 50 m), Baja California Sur, Mexico: 1 ♀ on point with following five labels: “Mex. Baja Cal. Sur Las Barracas 17 - V - 1985”, “Coll. P. DeBach Pan trap”, “Avetianella ♀ Det. V. Trjapitzin May 1997”, [red] “Paratypus ♀ Avetianella hasmik Trjapitzin”, “Praep. micr. 22M” (an antenna, head, and a forewing were detached from this specimen; they are mounted on a slide with following two labels: “Avetianella hasmik ♀ Trjapitzin México: Baja California Sur, Las Barracas. Pan trap 17.V.1985 (Coll. P. DeBach) 22M Antena, cabeza, ala anterior”, [red] “Paratypus Avetianella ♀ hasmik Trjapitzin”); also 16 ♀, 1 ♂ on points, all collected by P. DeBach during 1985 and 1986, as indicated by Trjapitzin (2001).

One female [UANL] of this undescribed species from Mexico, which has no host information, was mentioned by Trjapitzin and Volkovitsh (2011); however, they did not indicate the collecting locality so it is unknown from which part of that country it was found (Nearctic or Neotropical).
