Distinguishable from all other known species on palm by the pres- 

 ence of dorsal tubular 8-shaped pores and the shape of the marginal 

 and dorsal 8-shaped pores. Although Green stated, "No supple- 

 mentary paired pores on the dorsum" (4-7, p. 470), they are fairly 

 distinct in all specimens examined. 



Asterolecanium pinangae, new species 



(Fig. 53, A-E; pi. 9, 0) 



Habit. — Living on both surfaces of leaves, and on bark. 



Test of female. — Elongate, nearly elliptical, 1-1.5 mm. long, 0.5-1 wide; flat 

 dorsally and ventrally, with a faint longitudinal median carina dorsally ; green- 

 ish or clear yellow, transparent, punctate; marginal filaments very pale salmon; 

 larval exit ovoid, in dorsal surface at margin. 



Adult female. — Nearly elliptical, posterior end narrowed; 0.9-1.25 mm. long, 

 0.3-0 6 wide. 



Margin : 8-shaped pores in a single row terminating approximately a pore's 

 length from bases of apical setae, 9 fi long and 4 wide, less than a pore's length 

 apart; quinquel ocular (sometimes nearly as many trilocular as quinquelocular) 

 pores in a single row, starting 6-20 8-shaped pores anterior to anterior spiracular 

 pore bands and ending the same distance posterior to posterior spiracular pore 

 bands (the row sometimes narrowly interrupted between pore bands), the 

 pores as numerous as corresponding 8-shaped pores at ends of row, somewhat 

 more numerous elsewhere. 



Dorsal surface: Minute 8-shaped pores fairly numerous; disk pores sparse; 

 tubular ducts 28 fi long. 



Ventral surface: Antenna a slightly raised, irregular area, with 2 setae as 

 long as diameter of antenna; beak apparently with 2 pairs of setae; spiracle 

 with bar slender, atrium enlarged, bag-shaped, and containing 3-6 quinquelocular 

 pores, 5-12 similar pores extending from spiracle to body margin in a single 

 low; multilocular pores, with 10 loculi, in 7 interrupted rows, the posterior 

 row with 2 or 3 pores, penultimate row with 6 or 8, and each of the other rows 

 with 1-4, the total ranging from 18-24; 2-4 dark-rimmed 8-shaped pores each 

 side of beak and a few in an irregular row on abdomen ; submarginal 8-shaped 

 pores in a single row terminating near the posterior row of multilocular pores, 

 about one-half as numerous as corresponding marginal 8-shaped pores; sub- 

 marginal setae in a complete row terminating near the penultimate pair of 

 marginal 8-shaped pores ; 2 pairs of setae in posterior row of multilocular pores 

 and 1 pair in each of the next 3 rows. 



Apex of abdomen : Lobes sometimes indicated ; setae, apical 36-44 fi long, 

 interapical about 2.7 n long, outer ventral 3 ti long; anal opening apical; anal 

 tube very short, often indeterminable : anal ring somewhat elliptical, consisting 

 of a sclerotized band surrounding 2 short, sclerof zed collars, each collar with a 

 seta 16 m long and a minute pore: a membranous opening contiguous to ventral 

 sides of collars ; ventral surface of apex slightly sclerotized directly anterior to 

 apical se^ae. 



Larva. — Nearly elliptical, posterior end slightly narrowed. 



Margin : With 28 8-shaped pores, posterior pores sFghtly smaller than the 

 others, axes of all longitudinal ; a minute seta close to each pore of the posterior 

 3 pairs; 3 rairs of setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of 2-9 and a lateral row 

 of 9-11, on each half of body, majority of lateral pores as long as width of 

 marginal pores, but 1 or 2 near anterior end at least as large as marginal ; 

 the posterior pore and 1 or 2 anterior pores of the submedian row virtually as 

 large as marginal pores, the others distinctly smaller, submedian pores occur- 

 ring near posterior end of body and usually at the anterior end but the row 

 often interrupted medially ; disk pores between Kteral and marginal 8-shaped 

 pores. 



Ventral surface : Antennal setae, I, ; IV, 1 ; V, 1 ; VI, 3 long, 2 stout, 2 fairly 

 stout: antennal bases three-fifths length of antenna apart; beak apparently 

 with 3 pairs of setae at tip ; anterior spiracle with 2 trilocular or quinquelocular 

 pores, posterior spiracle with apparently 2 quinquelocular pores ; leg setae, coxa 

 3, femur 0, tarsus 1 each on inner and outer margins ; tibia one-fourth as long 

 as tarsus, articulation between tibia and tarsus very indefinite; 9 pairs of 

 submarginal 8-shaped pores ; 10 pairs of submarginal minute setae, on abdomen, 

 thorax, and head ; 4 pairs of setae near antenna > and mouth parts.
