  • Aulacaspis Cockerell, 1893: 180.

Type species

Aspidiotus rosae Bouché: by subsequent designation by Newstead, 1901: 168.

Generic diagnosis

Female scale. White, circular, exuviae located on front end.
Male scale. White, long and narrow, exuviae located on front end.
Adult female. Body shape varied, mushroom-shaped, fusiform or cuniform; derm membranous except for the margin of pygidium; prosoma swollen or wider than metathorax and abdomen, slightly squared in most species. Cephalothorax. Antennae each with a seta. Anterior spiracles each usually with a cluster of trilocular pores, posterior spiracles each with or without associated trilocular pores. Dorsal ducts present or absent on prosoma, scattered. Pygidium. Usually with three pairs of lobes (rarely with two or four pairs). Median lobes (L1) well-developed, much larger than lobules of lateral lobes, zygotic basally, without marginal setae between lobes. In general, L1 are divided into two types depending on feeding site: bark-type, where individuals occur on bark and L1 protrudes at the end of the pygidium; and leaf-type, on leaves and L1 is sunken into the end of pygidium. Second lobes (L2) much smaller than L1, bilobed, divided into inner lobule and outer lobule, outer lobule usually smaller than inner. Third lobes (L3) smaller than L2, bilobed, outer lobule smaller than inner. Fourth lobes (L4) present in some species and usually represented by serrations along the body margin. Gland spines. Marginal gland spines developed, present on lateral of abdominal segment II and III; usually single on abdominal segments V-VIII, but in some species there are two or more. Marginal gland spines becoming shorter to conical on anterior segments; in some species they are called gland tubercles. Ducts. Dorsum with double-barred ducts. Marginal macroducts of pygidium usually larger than dorsal macroducts. Dorsal macroducts forming submedial and submarginal rows on abdominal and pygidium, sometimes occurring in two sizes. Ventral microducts scattered. Anal opening situated at the center of the pygidium, small. Perivulvar disc pores in five groups.

Remarks

Members of this genus, like other members of the subfamily Diaspidinae, have a pygidium with macroducts of the two-barred type, the second pygidial lobe bilobulate, and fringed plates absent between the lobes, but Aulacaspis is distinguished from other genera, especially Chionaspis Signoret, 1868 by having a remarkably swollen prosoma. Moreover, Aulacaspis lacks lateral macroducts and gland spines on abdominal segment I and on the thorax, present in these locations on Chionaspis. Furthermore, Pseudaulacaspis MacGillivray, 1921 is similar in features of the body, but can be distinguished by the presence of a pair of setae between the L1, which are absent in Aulacaspis.
