- W2547620978 abstract "The apterae and alatae viviparae of a new species of Sensoriaphis are described from Nothofagus on Mt Kaindi, Papua New Guinea. Keys are provided to the apterous and alate viviparous morphs of the described species of Sensoriaphis. Sensoriaphis niuginii Carver, new species Apterous viviparous 9 (macerated specimens). Body length 1.5-2.2 mm (mean, 1.89mm), approximately 2 * as long as maximum width. Marginal tubercles on meso-, metathorax and abdominal segments I-IV hardly developed; on abdominal segments I-IV, represented by groups of 1-4 small, capitate hairs on scleroites; 1 of these scleroites in each group may be slightly raised and bear a single, capitate hair that is slightly longer (7-13//) than the other hairs. Marginal tubercles on abdominal segments VI and Vll very low or almost flat, dark, spinosely imbricated; on segment VI with 2-5 various-sized capitate hairs, the largest being 13-29//; on segment Vll, with 2-3 hairs, the largest being 21-43// long. Abdominal tergite VIII well demarcated; on rounded posterior margin 2 dark, imbricated, fingerlike spinal tubercles, 0.07-0.16mm long (mean, 0.11mm), 0.03-0.06mm wide at base, each bearing at its apex a capitate hair, 29-40// long; spinal tubercles flanked on each side by 2-3 large, subequal, capitate hairs, 20-43// long. Other dorsal, thoracic and abdominal hairs small, capitate, 3-8// long; pronotum with 2 hairs anterospinally, 2-4 hairs posterospinally, 1 hair in each anterolateral margin near eye, and 4-8 irregularly disposed hairs laterally on each side on a dark, somewhat rugose, marginal area; mesonotum with 31-46 and metanotum with 19-22 irregularly disposed hairs; abdominal tergites I-V each with a row of 7-11 spinopleural hairs and 1 submarginal hair on each side; tergite VI with 4-9 spinopleural hairs and 0-1 submarginal hairs on either side; tergite Vll with 2 spinal hairs. Ventral abdominal hairs longer, acute. Two small, round, spinosely imbricated areas present, pleurally, on sternite V at bases of a few ofthe ventral hairs. Pronotum dark, except for median, pale area; mesonotum and metanotum with large, roundish pleural sclerites, dark rugose marginal areas and irregularly shaped scleroites at bases of most of hairs; abdominal tergites I-V with large, irregularly-shaped submarginal sclerites and irregularly-shaped, variously-sized scleroites at bases of hairs; on tergite VI, the scleroites tend to coalesce with one another and with the slightly, spinosely imbricated transverse sclerotic band on tergite Vll; tergite VIII wholly dark, distinctly darker than other tergites and spinosely imbricated; intersegmental sclerites most evident between tergites V and Vll. Head with frons slightly produced medially and bearing 2 capitate hairs, 21-33// long; dorsally, near antennal bases, 2 dark tubercles, each bearing a capitate hair, 21-29// long; posterior and median to these tubercles, a pair of small, capitate hairs, 4-7// long and, between the eyes, a row of 4 similar, small hairs; head, ventrally with usually 3 pairs of hairs, the anterior pair just posterior to frontal hairs, capitate to blunt, 19-30// long, the middle pair medially placed, stout, blunt, 27-37// long, the posterior pair similar but more laterally placed and maybe slightly smaller; head dark, often with a faint, reticulated pat tern. Eyes compound, each with a dark, conspicuous triommatidium. Antennae 0.71-1.14mm long (mean, 0.89mm), 0.43-0.53 x body length, 6-segmented; primary rhinaria nonciliated, secondary rhinaria normally absent (2 rhinaria present in 1 specimen); antennae darker than head; segment III may be paler than other segments; segment I broader than long, segment III often broadened at base; flagellar segments heavily 1. Material examined is partial results of fieldwork supported by grant GB-34986 to Bishop Museum from the U.S." @default.
