ZooKeys 2018 782 11 47 http://zoobank.org/50D7573E-59B7-4901-8F77-EE3EB25290AD Insecta Diaspididae Greeniella CoL Animalia Greeniella dacrydiae Hemiptera 0 11 Arthropoda species dacrydiae  Material examined. Holotype: New Caledonia: 1 adult female (0.49 mm long, 0.38 mm wide): ex Dacrydium auricarioides [sic; the correct spelling of the epithet is araucarioides], 5 miles north of YateDam Lake, 5.ix.1963, SW Brown, SWB accession 275 (USNM). Paratype: New Caledonia: 1 second-instar exuviae: on same slide as holotype, SWB accession 275 (USNM).  Description. Adult female, n = 1. Pupillarial. Body of holotype 0.49 mm long, broadest at meta-thorax and anterior abdominal segments (0.38 mm); body outline ovoid, with slight constriction at head. Pygidium truncate, without dorsal macroducts, or typical lobes and plates; with ~20 short papilliform projections. Anus circular, in anterior half of pygidium. Venter with vulva in posterior half, well behind anus. Perivulvar pores absent. Microducts scattered along posterior margin and submedial areas. Pre-pygidial segments. Dorsum with few setae along margin. Venter with microducts scattered across abdominal segments, in clusters around each spiracle. Fine setae in distinct submedial and marginal series. Antennae each with one long setae. Spiracles without pores. Second-instar female.Pygidium with three lobes on each side; L1 longer than wide, parallel-sided, apex oblique; L2 and L3 sub-triangular, with oblique caudal edge, medial margin much longer than lateral margin. Two simple gland spines in each interlobal space, and lateral of L3. Marginal two-barred macroducts with thick sclerotization around orifice; one between L1 and L2, L2 and L3, and laterad of L3; longer slenderer macroduct arising from base of each marginal gland spine. Anus circular, near middle of pygidium.  Figure 8. a Adult female of Greeniella dacrydiaesp. n. with b enlargement of pygidium.  Figure 9. Pygidium of 2nd instar of Greeniella dacrydiaesp. n.  Comments. The adult female of G. dacrydiaecan be easily distinguished from those of other described species by the ~20 papilliform projects along the truncate posterior margin of the pygidium.
