Acanthococcus aceris Signoret, 1875 (Eriococcidae: Acanthococcus)Nomenclatural History
- Acanthococcus aceris Signoret 1875b: 35-36. accepted valid name Notes: "No original material has been traced. The specimens from Austria, one of the type-localities, are from the Naturhistorisches Museum, Vienna, identified by F. Löw, and the specimens from Switzerland are from the collection of P. Marchal. There seems to be no doubt about the identity of the species now recognized as such by many modern workers." (Williams, 1985h) Matile-Ferrero & Danzig visited the Naturhistorisches Museum, Vienna in June of 1997 and were unable to locate any type material of this species.

Remarks
- Systematics: Slide-mounted adult female with: dorsal setae abundant over dorsum; microtubular ducts bifid; frontal lobes slightly smaller than first antennal segment; anal lobes with medial teeth and 3 dorsal enlarged setae (Williams, 1985h). According to Hodgson & Trencheva (2008), the first-instar nymph of A. aceris is easily separable from that of A. melnikensis and A. roboris because all of the dorsal spinose setae forming the double mid-line are sharply pointed and subequal in size. Those of A. melnikensis and A. roboris are basically of two sizes, those on abdominal segments II-V being small to minute; and all spines are truncate rather than sharply pointed. In addition, the 1st instar nymph of A. aceris lacks spinose seta submedially on the head, whereas one is present on each side of A. melnikensis and A. roboris. Gavrilov, 2010, stated that it is not known if the differences between larvae from different localities different host plants, etc are likely to be significant. However, he stated that a comparison of adults of A. melnikensis and adults of A. aceris in a collection in St. Petersburg from different locations, suggested that these two species appeared to be identical and he considered A. melnikensis a new junior synomym of A. aceris. However, Spodek, et al., 2014, compared specimens of A. melnikensis from Israel and A. aceris from Greece and Hungary and concluded that they were different species. Adult female A. aceris differ from those of A. roboris in having (character traits of A. roboris in brackets): (i) all measurements rather smaller; (ii) few or no small macrotubular ducts ventrally on abdominal segment VII (8-12): (iii) fewer than 10 small macrotubular ducts present across abdominal segment VI-II (mainly more than 15 and sometimes over 30 across some segments); (iv) segment III of the antennae without setae (setae apparently always present on segment III on A. roboris). (Hodgson & Trencheva, 2008) The 2nd-instar male is immediately separable from the 2nd-instar female by the presence of macrotubular ducts. It differs from the 2nd-instar male of E. roboris in being rather smaller, in having fewer cruciform pores, in the shape of the median plate, and in geneally having small submedial truncate dorsal setae only on abdominal segments VI and VII (rather than II-VII). (Hodgson & Trencheva, 2008)
- Structure: Ovisac compact, gray. Adult female oval, chestnut colored, covered with white wax powder (Kosztarab & Kozár, 1988).
- Biology: Species overwinters as second instar. Adults develop by the first half of April and complete egg laying by the end of May. 82-378 red eggs are laid per female. Eggs hatch in about 30-35 days. First instars feed on leaves, and return to bark for overwintering in September and October. In Hungary, all eggs hatched by mid June. Also has been found at altitudes of up to 1,500 m in elevation. The species has also been observed with ants feeding on the honeydew (Kosztarab & Kozár, 1988).
- Economic Importance: This species is rarely a pest in urban situations (Kosztarab & Kozár, 1988).
- General Remarks: Detailed description and illustration by Williams (1985h)Gavrilov-Zimin & Kurochkin (2019).. According to Borchsenius (1934) the species does not occur in middle Asia as recorded by Archangelskaya (1923). Detailed description and illustrations in Hodgson & Trencheva (2008).
