secondary scoli present on abdominal segments three through eight 
immediately anterior to each primary pair (ScAbd). Anteriormost 
pair of body scoli longest, measuring half the length of head capsule; 
primary scoli become progressively smaller posteriorly, then sub- 
equal from first to eighth abdominal segments. Mesothoracic spira- 
cles (SpMs) very large, borne dorso-laterally on cone-shaped sclero- 
tized tubercles behind prothorax; all other spiracles smaller, those 
of first two abdominal segments dorso-lateral (SpAbd 1 & 2), re- 
maining six pairs ventro-lateral. 
Chaetotaxy: Dense fringe of serrate dolichasters present on lateral 
and labral margins of head capsule and peripherally on ocular 
tubercle, prothoracic shield and tubercle, ninth abdominal seg- 
ment, and all scoli; longest on scoli, lateral margins of labral lobes 
and anterior margins of ocular tubercles. Antennal tubercle bearing 
a group of three small slender setae with apical stellate enlargements 
(SSt and figure 8-d) that contact antennal scape, flanked anteriorly 
by one to several stouter, serrate setae. Dorsum of head and body 
more or less covered by complex but minute scale-like setae (Scl 
and figure 8-e) interspersed with medium-sized dolichasters, the 
latter aggregated into pairs of tight clumps (one pair per segment) 
on middorsal surfaces of abdominal segments one through seven; 
setae nearly absent from midline of body. Ventral surface of body 
uniformly and thickly clothed with small, sharply flared dolichasters 
which become more peg-like or lanceolate on head capsule. A single 
long, lanceolate seta present on ventral surface of each trochanter; 
other, shorter lanceolate setae profusely present on ninth abdom- 
inal sternum, nearly obscuring the five terminal pairs of tooth-like 
digging setae. 
Species Description: Ascaloptynx furciger (McLachlan), new 
larval association. 
Measurements: Length of mature larva, 16.80-21.80 mm, mean 
length = 19.25 mm. Length of head capsule, 4.00-4.50 mm, mean = 
4.35 mm; width of head capsule, 4.37-4.90 mm, mean = 4.57 mm. 
Chaetotaxy: Dolichasters on lateral margins of head capsule 
short and stout; those on dorsal aspect of head with closed tips.
