Aceria calaceris

Eriophyes calaceris

Hosts: Acer glabrum, Acer heldreichii, Acer macrophyllum

Relationship: These mites are found in and probably cause the red erineum on leaf tips [upper surface]; produce bright red erineum on upper leaf surfaces.

Notes: This mite's records from Acer negundo L. in the east are probably Aceria negundi (Hodgkiss, 1913) [white or brown erineum, not red]. All three erineum mites should be carefully studied and rearing studies conducted.

Range: CA, SD, WA

Aceria elongata

Erineum roseum
Eriophyes regulus
Eriophyes elongatus

Hosts: Acer saccharum

Red erineum patches on the upper surfaces of leaves.

Note about Erineum roseum Schultz (Harlow): Hagen (1885) p. 24, # 25, "Acer saccharinum Wang". Pl. [Place] Shelburne, NH, August 1882. Prof. Harlow [collector of fungi]. Erineum roseum Schult. (Farlow); small velvety patches [red] on the upper surface of leaves. [This shows the great confusion in the names of the maples; Silver Maple, Acer saccharinum, never has red erineum on the upper surface of the leaves. The host was actually Acer dasycarpum Ehrh., regarded by , the old name for the sugar maple, Acer saccharum L. I have collected it many times from Sugar Maple.]

"Aceria regula is the deutogyne and a junior synonym; Aceria elongata is the protogyne; Aceria elongata has seniority by pagination in the 1913 paper (#272)" based on comments in #4062. Aceria regula is not the deutogyne; the deutogyne lacks MT on dorsal opisthosomal annuli; Hodgkiss illustrated a mite with complete dorsal microtuberculation and a distinctive shield pattern. Aceria regula is probably an inquiline that occurs in the red erineum in New York. 

Range: MI, NY, WV, Canada

Aceria modesta

Eriophyes modestus

Hosts: Acer saccharum

Relationship: Whitish or greenish erineum patches on the lower surfaces of leaves or along the veins.

Range: Canada, NY, WV

Aceria aceris

Eriophyes aceris

Hosts: Acer saccharinum

Relationship: The mites causes greenish to reddish erinea on lower leaf surfaces.

Notes: Probably occurs on silver maple throughout eastern North America.

Suggest Aceria hodgkissiae for this erineum mite. This distinctive mite species needs a new name; it is a junior homonym of Aceria aceris (Murray, 1877), which is a valid mite species in Europe causing elongate, red carmine galls, filled with hairs, with a large open aperture on the leaf underside, with leaf-hairs protruding; it occurs on Acer pseudoplantanus, the Planetree Maple, in Europe

Range: NY, MA, VT, WV, WI

Aceria major

Range: Finland, NY?, WV

Aculops rhois

Eriophyes sp.

Hosts: Toxicodendron radicans ssp. radicans, diversilobum, vernix

Relationship: "Corrugations (galls) on upper and lower surfaces of leaf with numerous, whitish hairs or erinea"; leaf deformation; stunting of plant? Flowers of large vines sometimes become deformed producing numerous long narrow filaments that are narrow rolled leaves; mites develop in large numbers within the rolls; in some cases the filaments are somewhat more leaflike (West Virginia: Monongalia, Nicholas, Preston and Tucker counties; Maryland: near mouth of Susquehanna River). Are these a different species?

Range: MA, CA, FL, GA, IN, MD, OH, PA, SD, WV

Notes:

Amrine & Stasny, 1994, erroneously listed this mite as nomen nudum. The mite described by Stebbins meets all code requirements for an older description: "a name, a mention of the animal and a description of the work of the animal"; thus her name is valid and has priority over Ewing's toxicophagus. We hereby elevate her name, Eriophyes rhois Stebbins 1909 to the accepted name for the poison ivy ( Toxicodendron radicans) gall mite. Ewing's Phyllocoptes toxicophagus is valid and occurs on Toxicodendron diversilobum. The deutogyne of rhois was photographed by Briones & McDaniel, 1976, 41, f. 88 and was observed by J. Amrine, 2 Sep. 1998 on specimens collected from Monongalia Co. WV, Cobun Creek Trail, by pasture, south of Cobun Creek Rd, 1 Sep, 1998, ex poison ivy (Toxicodendron radicans); they need to be described. The name rhois is a modified form of Rhus. Mites, if they occur on Toxicodendron pubescens Mill. (Atlantic Poison Ivy) and T. rydberghi (Small ex Rydb.) Greene (Western Poison Ivy) may all be separate, distinct species.  

Nalepa 1929 listed on p. 124, under Rhus radicans, Eriophyes rhois Stebbins 1909, and under Rhus diversilobus, Phyllocoptes toxicophagus Ewing, 1922; it may be that galls on each species of Rhus is caused by a different mite. Very careful morphological studies should be done, with rearing experiments and DNA studies. Probably, Aculops toxicophagus (Ewing) will be the name for the mite causing galls on Rhus diversilobus, and Aculops rhois (Stebbins, 1909) for the mite causing erineum galls on Rhus radicans.

NOTE: Inflorescences of Rhus radicans often have flowers & fruits formed into long foliar filaments, with the edges curled in toward the upper midrib, containing numerous mites and a few hairs. Much of this dries up during the season and becomes brown or black and brittle, resembling Spanish Moss on poison ivy. But, many deformations continue to have parts of the deformity growing, tender and green containing mites eggs and offspring even into November. Deutogynes in August were more common in older filaments; protogynes and developing mites in the tender growth. Deformed fruiting bodies have been found at cliffs at Blackwater Falls St. Park (Tucker Co., WV),at the Summersville Library on several large plants on three large trees (Nicholas Co.), at I-79 Rest Area N. Bound, north of Clarksburg, Harrison Co., WV, at Cheat Lake south of Mont Chateau (WV Geological Survey), at Cheat Lake, Morgan's Run Park and Trail, at Monongahela River, just south of the Morgantown Dam, east side along bike path, and at 24 Pinnacle Lane, Monongalia Co., WV. Originally, the foliated fruit was thought to be injury from glyphosate (A.I. of Roundup herbicide), but, symptoms have been found where pesticides have never been used. These mites are very similar to Aculops rhois and careful descriptions should be made to determine if one and the same species causes both kinds of deformities. It is not known if this symptom occurs on Poison Oak, Poison Sumac or other species of Rhus in North America. Examination of large hedgerows of poison ivy in New Orleans failed to find any of this new symptom. So far, it has only been found in several locations in West Virginia, in Bridgeport, Morgantown, Cooper's Rock State Forest, and Black Water St. Park in Tucker Co. 

Eriophyes laevis

Bursifex alni
Phytoptus laevis
Phytoptus pustulatum

Hosts: Alnus glutinosa, incana, rugosa, tenuifolia, pubescens, rhombifolia, rubra, viridis. [Betula papyrifera and Salix nigra listed as likely mistakes reported in the literature]

Relationship: Numerous cephaloneon galls of various sizes, on both leaf surfaces (mostly upper); Cephaloneon pustulatum Bremi.

Range: Europe; CA, GA, KS, WA, WV

Notes: 

Host associations on some plants are probably missidentifications, such as Betula papyrifera.

This may be a complex of very similar species, each restricted to one or two species of Alnus.

Amrine & Stasny (1994) mistakenly made laevis (Nalepa, 1889) a nomen nudum; they did not see the brief description on p. 132, which is sufficient according to the code.

Aceria baccharipha

Eriophyes baccharipha

Hosts: Baccharis pilularis

Relationship: Leaf blisters.

Range: CA, FL

Aceria brachytarsa

Aceria amiculus
Eriophyes brevitarsus

Hosts: Juglans hindsii, californica, nigra

Relationship: Undersurface purse galls; purse galls filled with parenchymatous tissue and sparse hairs, with channels for mite development. The leaf gall on Juglans nigra is mostly on the upper surface and hollow with hairs; nothing like this gall. 

Range: CA, OH, WA, WV

Notes: 

Eriophyes brevitarsus was preoccupied by the senior homonym, Eriophyes brevitarsus Fockeu, 1890, which was later assigned to Acalitus brevitarsus (Fockeu). Farkas (1965) changed the spelling to Aceria brevitarsa (Fockeu).

Aceria amiculus (Keifer, 1940) is the deutogyne and junior synonym according to Keifer (1969), in C3 [358: 15].

The mite causing leaf galls in Juglans nigra is a different species.

Aceria caulis

Erineum anomalum
Juglandis caulis
Acarus caulis

Eriophyes? amelanchieri
Hosts: Host originally listed as Amelanchier canadensis L., then Amelanchier ×intermedia Spach (pro sp.) [arborea × canadensis], and back
Rounded galls on upper leaf surface, open on lower surface by an elongate tube that splits open at maturity (could it be a Phylloxera?).
If they are eriophyoids, then the description is valid; otherwise, if they are Phylloxera or another insect, then the name is nude

Species: Vasates oldfieldi
Description: In numerous, short finger galls on leaves
Originally described as Eriophyes lionotus (Nalepa) by Wilson & Oldfield, 1970.
Hosts: Betula occidentalis

Aculops arizonarhus Keifer, 1966
Host: Rhus microphylla
Relationship: The mites apparently deform flower bud.

[The Amrine catalog has three entries associated with Bucida buceras [Terminalia buceras]: 

Colomerus bucidae (Nalepa 1904), a valid species with synonyms Eriophyes buceras and Colomerus bucidae
Relationship: "Erineum in leaf bulges- upward."
Note: "There may be three separate species here: one causing erineum, one causing leaf galls, and one causing the flower galls described by Trotter, 1929. This host plant and its mites need further study."

Colomerus buceras (Trotter 1929), tentatively asserted as a deprecated synonym of Eriophyes bucida (Nalepa, 1904)
Relationship: "Greatly elongated, slender, hollow, horn-shaped outgrowth on flower, about 19 cm long (instead of the normal fruit measuring only 5-6 mm) and about 2-4 mm thick. The gall cavity contains numerous fleshy irregular emergences. Some of the galls on inflorescence develop into witches' brooms."
Note: "This appears to be a valid species that is distinct from and precedes Eriophyes buceras Cromroy, 1958. This mite was missed by Davis et al., 1982, and by Amrine & Stasny, 1994."

Colomerus buceras (Cromroy, 1958), a deprecated synonym of Colomerus bucidae
Relationship: "Deformed fruit, leaf erineum, and two types of galls [galls were not described]."
Note for C buceras reads: "Is this the same species described by Trotter in 1917 (Eriophyes buceras Trotter, 1929)? If they are different species, then this mite needs a new name. The symptoms may be describing 2 or 3 species."]

Aceria pallida Keifer, 1964

Host: Lycium pallidum, carolinianum, barbarum

Relationship: Leaf blisters

Locality: AZ

Considered a jun syn of Aceria kuko by Kuang 1983 and Huang, 2004

Acalitus blastofagi

Aceria blastofagi

Type host: Dwarf Beech (Bonzai), Fagus sp. (probably F crenata; Fagus sylvatica L. is also used for beech Bonsai; the two species  are very similar).

Relationship: the mites form galls in the buds

Type locality: Japan, intercepted at airport in California

Acalitus ferruginea (Stebbins, 1909)

Erineum fagineum Persoon, 1822
Acalitus fagerineus (Keiger, 1959)
Acalitus ferrugineum (Farlow &Hagen, 1885)
Acalitus ferrugineus (Stebbins, 1909)

Host: Fagus grandifolia

Relationship: "Yellow erineum patches on the upper surface of the leaf: compound capitate papillae."; Erineum on leaf undersurface; "numerous granules on leaf undersurface, discolored pustules above; at first frosty, later brown."

Distribution: FL, MA, NH, PA, OH, WV

Notes: Persoon (1822) described Erineum fagineum Persoon as a fungus, producing erineum patches on leaves of Fagus sylvatica L.; thus, this name is not available as a mite name.

Hagen (1885) created the name Erineum ferrugineum P. (Farlow) (P. apparently refers to Persoon) for the mite producing erineum on leaves of Fagus grandifolia Ehrh. Farlow gave a collection of beech leaves with erinea by this mite to the Cambridge Museum; Hagen described the symptoms as "Irregular velvety rusty patches on the underside of the leaves." The mite was given the name Acalitus ferrugineum (Farlow & Hagen, 1885) by Amrine and Stasny (1994): Persoon was dropped as he had no connection with the name ferrugineum and he thought a fungus caused the symptom; Farlow was retained, since it had been used by both Hagen and Stebbins; no publication by Farlow has been found.

Stebbins (1909) listed the name Eriophyes? ferruginea Farlow as the mite producing erineum on leaves of Fagus grandifolia L. This name was not listed by Davis et al. 1982, nor by Amrine & Stasny, 1994. Stebbins was the first to assign the mite to Eriophyes (apparently derived from the name Erineum ferrugineum P. (Farlow) listed by Hagen (1885). Stebbins is thus the author of Eriophyes ferruginea producing erineum on the leaves of American Beech.

One mite forms erinea on both surfaces of the beech leaf. We found two different mites in the two different erinea (Garman suspected this in 1894, but failed to provide names); we found an Aceria in the lower surface erinea and an Acalitus in the upper surface erinea. Earlier versions of our electronic catalog listed the mite causing the lower leaf surface erineum, as Aceria ferrugineum (Stebbins, 1909) and the mite causing the upper surface erineum, as Acalitus fagerinea (Keifer), but this was wrong. Careful study has found two species of Aceria that are inquilines in the erinea on both leaf surfaces; and these can become so abundant that sometimes, only an Aceria can be recovered from an erineum. 

Aceria durmitorensis (Petanovic & Boczek, 1990)

Eriophyes durmitorensis Petanovic & Boczek, 1990

Host: Fagus sylvatica L. subsp. moesiaca

Range: FL, GA, MD, NC, WV

Cenalox conyssae

Hosts: Nyssa sylvatica

Relationship: Elongate, lower surface, leaf pockets filled with hard lobes, along leaf veins. The galls cause protrusions on upper leaf surfaces.

Eriophyes leionotus

Phytoptus leionotus
Eriophyes lionotus
Eriophyes laevis lionotus


Hosts: Betula pendula, concinna, coriacea, pubescens, maximowicziana, odorata, occidentalis?, pubescens tortuosa, semipendula

Relationship: Leaf nodules (small cephaloneon galls on upper leaf surface); erineum (same mite?)

Notes: This mite has been in Phytoptus, Eriophyes, Phyllocoptes, Aculus and Aceria [several authors classified it based on the deutogyne instead of the protogyne]; it belongs in Eriophyes. Amrine and Stasny (1996, #2306) moved Aculus leionotus (Nalepa 1891), #1180, to Eriophyes leionotus (Nalepa 1891) based on examination of protogynes; they corrected the habit from erineum to leaf nodules (Cephaloneon betulinum). This species was described from the deutogyne, which would be placed under Aculus. Nalepa (1919, p. 33 and 1923c, p. 38) emended the name to lionotus, but the emendation has not been generally accepted. We follow Liro & Roivainen (1952) and spell it leionotus.

Phyllocoptruta rubigator

Notalox rubigator

Hosts: Acer saccharinum

Relationship: "The mites are lower surface, leaf feeders, causing considerable rusting"; collections in Morgantown, WV, 23 Aug 2012, found the mites, in all stages, including deutogynes, in considerable numbers on the upper leaf surface only, no apparent injury was observed [vagrant].

Range: MD, WV

Aceria marshalli

Eriophyes marshalli

Eriophyes tiliae exilis
Aceria exilis

Hosts: Tilia platyphyllos subsp. cordifolia, cordata, platyphyllos, americana, americana var. heterophylla, japonica,  petiolaris, tomentosa, zamoyskiana 

Relationship: Vein angle galls with outer hair (on leaf undersurface?)

Range: [Europe] 

Note: Eriophyes exilis is a valid species producing vein angle galls on the underside of the leaves of Tilia platyphylos Scop.; it does not cause erineum on several species of Tilia as published by Soika & Kozak, 2013; their erineum mite, labeled Eriophyes exilis (Nalepa, 1892), is Eriophyes leiosoma (Nalepa, 1892).

Range: IL, IN

Eriophyes? salicaesemen [listed as junior synonym of Eriophyes? semen]

Host: Salix nigra?

Relationship: Galls

Range: IL

Notes: The gall was originally described in 1864 as Salicis semen. See Chadwick 1908, p. 146, for early synonymy. This name was missed by Davis et al., 1982. Is this gall-forming mite the same as Aculus tetanothrix (Nalepa)? Is it another sibiling species? Then, salicaesemen would hold priority. Amrine & Stasny (1994) combined the two names provided by Walsh without knowing that it had already been designated semen by other authors.
