Neotoumeyella Kondo and Williams, 2009

Type species

Neolecanium leucaenae Cockerell, 1903

Generic diagnosis based on adult female (adapted from Kondo and Williams 2009). Body convex to globular, often irregular in outline, with thin glassy test, or covered with dull white waxy secretion. Ovisac reported as present for one species (i.e., N. cerifera ), but generally absent. Dorsum. Dorsal derm generally becoming heavily sclerotized at maturity. Dorsal tubercles, dorsal tubular ducts and pocket-like sclerotizations absent. Dorsal setae slender, stout, spine-like or lanceolate, with a round or pointed apex. All species with convex discoidal pores (preopercular pores) present around anal plates only or found widespread over dorsum. Dorsal microducts present, of 1 or 2 types, generally of 1 type, i) a microduct with well-developed septa, and a long terminal filament, distributed evenly throughout dorsum; ii) a type of microduct found so far in N. ferum ; known as a sclerotic pore, is a microduct surrounded by a large circular sclerotized plate (in N. ferum these are scattered on dorsum and form groups of 3–6 sclerotic pores in a rosette pattern around body margins). Anal plates with four apical setae, with variable numbers of subapical, fringe and hypopygial setae. Anal ring variable, with 6, 8, 10 or 12 setae. Margin. Marginal setae slender or stout and pointed or blunt. Stigmatic setae generally totaling three per stigmatic area (1–2 reported for T. ferum ), present on margin or slightly dorsal of margin. Eyes not detected. Venter. Ventral body setae sharply spinose, slender, straight or slightly bent; with a row of submarginal setae; interantennal setae totaling four or six; with three pairs of long prevulvar setae (reported as not differentiated in T. ferum ). Antennae and legs greatly reduced, with main segments present, occasionally indistinct or fused; without tibio-tarsal sclerotization. Antennae 3–6 segmented. Mouthparts normal, with eight labial setae. Spiracles usually large, about same size as legs. Spiracular pores with 3–8 loculi, mostly with five loculi (normally with 7 and 8 in T. ferum ). Ventral tubular ducts of 1–3 sizes, generally with a terminal filament, but without a terminal filament in T. ferum , present around vulvar area and anterior abdominal segments, always present in a submarginal band on abdomen and reaching area around posterior spiracular pore band, often found submarginally as far as anterior spiracular pore band, mouthparts and antennae. Multilocular pores (other than spiracular pores) variable, with 5–12 loculi, but pores with 5–10 loculi most common. Ventral microducts present, with a short terminal filament.

Remarks. Neotoumeyella ferum fits well the diagnosis of the genus.
