Macroporicoccus Nan & Wu, 2013 (Eriococcidae)

Nomenclatural History

• Macroporicoccus Nan & Wu 2013: 170-182. Type species: Macroporicoccus ulmi Tang & Hao . accepted valid name

Remarks

• Systematics: Adult females of Macroporicoccus Nan & Wu gen. n. can be easily distinguished from other eriococcid genera due to the presence of macrodisc pores, which occur throughout the dorsum and ventral margin. In addition, Macroporicoccus has 6-segmented antennae whereas Cryptococcus has 4-segmented antennae.(Nan, et al., 2013) Kuwanina Cockerell and Macroporicoccus live in crevices in the trunks and branches, and have many similar morphological characters. The shared features of the adult female are: (1) body subglobular covered by a white ovisac; (2) antennae reduced; (3) legs absent or reduced to tubercles, hind legs always replaced by pore-plates or vestigial flaps; and (4) anal lobes absent. However, adult female Kuwanina apparently differ in the absence of macrotubular ducts (C. nudata Brittin is an exception) and in the presence of unique invaginated 5-locular disc pores. (Nan, et al., 2013)
• Structure: Adult female: Body in life subglobular, orange-red, covered by a white ovisac. On slide, body circular or ovate. Antennae reduced, 6-segmented. Mouthparts developed, labium 3-segmented. Thoracic spiracles each with a group of disc pores, each with 3 or 5 loculi, near opening. Legs much reduced, only distal part of tarsus and complete claw visible; each claw with a denticle, hind legs each located on a pore plate. Anal ring circular or oval, with 6 short setae and no pores. Anal lobes indistinct. Macrotubular ducts with a cup-shaped invagination, present on both sides of body except ventral middle area. Microtubular ducts present on dorsum and margin of venter. Quinquelocular pores mainly present ventrally. Macrodisc pores present on dorsum and margin of venter. Setae small, sparsely distributed on venter. (Nan, et al., 2013) First-instar nymph: In life, body bright yellow. Body on slide oval. Antennae 6-segmented. Eyes present. Mouthparts and legs well developed. Anal ring circular, with 6 setae and without pores. Anal lobes each with one long and one short flagellate seta. Macrotubular and microtubular ducts absent. Quinquelocular disc pores present on ventral abdominal segments and near spiracles. Macrodisc pores distributed on dorsal surface. Setae present, forming transverse or longitudinal rows on body surface. (Nan, et al., 2013)
