Henderson 2011 (Diaspididae
Type species: Pseudodonaspis mollyae Henderson
type designation unknown
accepted valid name
- General Remarks: Description and illustrations in Henderson, 2011.
- Systematics: This monotypic genus demonstrates convergent evolution, induced by the grass-feeding habit shared with Odonaspis species; however, molecular evidence places P. mollyae closer to Symeria pyriformis (Maskell). (Henderson, 2011)
- Structure: Female scale cover thick dorsally and ventrally, white; male scale cover white, non-carinated, exuvium on 1 side. body roundly ovate to fusiform, derm membranous except for strongly sclerotised margins of the pygidium.
Dorsal ducts 2-barred, numerous, with sclerotised openings; marginal macroducts not much different in size to
submarginal ducts on pygidium; submedian ducts present on segments VI-IV; submarginal dorsal ducts present as
far forward as head, not extending onto venter. Dorsal bosses absent. Anal opening approximately circular, positioned nearer anterior edge than apex of pygidium. Median lobes widely separated by a deep median cleft
and with long basal scleroses forming sides of a ventral channel at base of medial cleft; lobes divergent, prominent, with several pairs of associated setae; 2nd lobes small, unilobular, 3rd lobes not visible. Gland spines absent. Stout segmental setae present (these could be mistaken for gland spines because their sockets apparently blend in with the sclerotised margin). Perivulvar pores, small ventral ducts, and gland tubercles
absent. Microducts numerous, with sclerotised openings, distributed as large groups on submargin of abdominal
segments, numerous microducts scattered on submedian abdomen, metathorax, and a few further anteriorly.
Anterior spiracles each with a group of trilocular pores, pores absent by posterior spiracles. Antenna with 2 or 3 long setae. (Henderson, 2011)
