Asterolecanium boliviae, new species 



(Fig. 8, M-V ; pi. 9, E) 



Habit. — Living on both surfaces of leaves. 



Test of female. — Elongate, truncate at anterior end, widest on anterior third, 

 tapering gradually to posterior end ; 1.4—1.5 mm. long, 0.4-0.5 wide ; dorsally 

 broadly convex from margin to margin, or strongly convex only in longitudinal 

 median area, with marginal area nearly flat, flat ventrally ; pale greenish yellow, 

 transparent, thin, slightly punctate ; marginal filaments brighter yellow than 

 body of test, shortest near posterior end ; dorsal filaments of same color as test 

 or slightly pinkish, arranged in a submedian row and twice as long as marginal ; 

 circular larval exit in margin. 



Adult female. — Shape similar to that of test, 1.25 mm. long, 0.4 wide. 



Margin : 8-shaped pores in a single row terminating around twice the length 

 of apical seta from setal bases, posterior pores 6-7 n long and 4 wide, others 

 9 m long and 5 wide, posterior 3 or 4 pores sometimes two or three times a 

 pore's length apart, others separated by less than the width of a pore ; trilocular 

 pores in a single complete row or interrupted at anterior end for about 7 8-shaped 

 pores, apparently usually terminating with the 8-shaped pores, approximately 

 one-third as numerous as 8-shaped pores at ends of row, usually half as numerous 

 as 8-shaped pores elsewhere. 



Dorsal surface : 8-shaped pores tending to be concentrated along submedian 

 line and scattered from it to margin, less numerous close to margin, particularly 

 at posterior end, 6 or 8 at intervals along submedian line, measuring 16-20 ll 

 long and 12-16 wide, the others 7-10 n long and 5 wide ; minute 8-shaped pores 

 sparse ; disk pores fairly sparse ; tubular ducts 28 //. long. 



Ventral surface: Antenna slightly raised, nearly circular, with 3 setae about 

 equal to, and 2 longer than, diameter of antenna ; 0-4 quinquelocular pores be- 

 tween antenna and margin; beak apparently with 2 pairs of setae; spiracle with 

 bar slender, widest at inner end, with atrium enlarged, shallow, and containing 

 4-7 quinquelocular pores, 3-5 similar pores extending to body margin in a single 

 row ; multilocular pores totaling about 22 and having 7-10 loculi, in 2 complete 

 and 3 or 4 interrupted rows, each complete row with 7 or 8, each interrupted 

 row with 2 ; 2-4 dark-rimmed 8-shaped pores each side of mouth parts, others 

 in a group posterior to antennae, in an irregular lateral row on posterior part 

 of abdomen, and in 1 or 2 transverse rows anterior to complete rows of multi- 

 locular pores ; submarginal 8-shaped pores in a single row terminating near 

 posterior row of multilocular pores, about one-half as numerous as marginal 

 8-shaped pores ; submarginal setae in a complete row terminating two-thirds 

 length of apical seta from their bases ; 2 pairs of setae in posterior complete 

 row of multilocular pores, 1 or 2 pairs in anterior complete row. 



Apex of abdomen : Lobes indicated ; setae, apical 46-56 fi long, interapical 8-10 fx 

 long, intermediate and outer ventral each about 3.6 m long ; anal opening ventral ; 

 anal tube very short, membranous ; anal ring sclerotized, apparently with 6 

 corrugations around outside, and with 2 setae each 20-24 n long arising from 

 outer section of ring ; ventral surface of lobe area slightly sclerotized in dentate 

 rows. 



Larva. — Elliptical. 



Margin : With 28 8-shaped pores, axes of all longitudinal ; a pair of minute 

 setae Hose to each of the posterior 3 pairs of pores ; 3 pairs of setae anteriorly. 



Dorsal surface : 8-shaped pores in a submedian row of 6 and a lateral row of 

 10, on each half of body, second pore from anterior end of submedian row larger 

 than marginal, all others minute ; disk pores near several lateral 8-shaped pores ; 

 a pair of minute setae near anterior pair of submedian 8-shaped pores. 



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

 stout ; antennal bases one-half length of antenna apart ; beak setae, 2 pairs apical, 

 1 pair basal ; spiracle with 1 trilocular and 1 quinquelocular pore, or with 2 

 quinquelocular pores ; leg setae, coxa 3, femur 1 on inner margin near base, 

 tarsus 1 each on inner and outer margins ; tibia one-fourth as long as tarsus ; 

 9 pairs (10 pairs in 1 of specimens studied) of submarginal 8-shaped pores; 

 apparently 10 pairs of minute submarginal setae, on abdomen, thorax, and head; 

 4 pairs of setae near antennae. 



Apex of abdomen : Notch small ; lobes indicated ; setae, apical 54 /j. long, inter- 

 apical 5.4 ju long, dorsal 1 \x long, intermediate ventral (nearly anterior to apical) 

 around 1 fi long, outer ventral (slightly outside apical) around 1 \x long; anal 

 opening indistinct ; anal tube membranous, very short ; anal ring circular, sclero- 

 tized, with 2 setae around 1 /x long.
