Abdomen: 1.80 mm. Trumpet: 0.28 mm. Pad- 
dle: 0.52 mm. 
Cephalothorax: Moderately pigmented; ap- 
pendage cases, meso- and metanotum darker. 
Trumpet dark throughout; length 4.0 median 
width; gradually widened from base to about 
0.4, then almost parallel-sided; inner wall dis- 
tinctly separated except in pinna; tracheoid 
extending to about 0.5 on lateral surface, well 
developed on mesal surface; reticulate dis- 
tinct, without conspicuous spicules; pinna 
0.27; distinct mesal slit in meatus extending 
about 0.27 of trumpet length. Hairs lightly 
to moderately pigmented; relative position, 
length, and degree of development as figured; 
larger branched hairs with slender basal stalk 
only slightly expanded apically where branch- 
es arise. Hairs: 1(4, 5b), 2(5b), 3(3, 4b), 4(5, 
7b), 5(6, 8b), 6(1), 7(4f), 8(6, 7b, external 
branches shorter), 9(4, 5b), 10(3b), 11 (4b), 
12(3b). 
Abdomen: Moderately and uniformly pigment- 
ed, ventral intersegmental scleroti 2 ations dark- 
er; tergites II-VII each with a posteromedian 
patch of distinct small spicules; tergite VIII 
with anteromedian patch of shorter, stronger 
spicules; tergal integumentary reticulations 
very faintly visible on I-IV, invisible caudally; 
sternites III-VII each with extensive median 
patch of small spicules; sternite II with caudal 
transverse band of lines of shorter, heavier 
spines; sternite VIII with anteromedian patch. 
All hairs moderately pigmented; relative po- 
sition, length, and degree of development as 
figured; larger hairs as on cephalothorax. Seg- 
ment I: hair 1(22, 26 primary branches, each 
branch densely barbed from near base, some

3b), 8(3b), 10(2f), 12(3f), 13(1), 14(1). Seg- 
ment VIII: caudal margin of sternite slightly 
emarginate; hair 0(1), 4(3f), 7(3, 4b), 14(1). 
Segment IX: hair 1(1, about 0.55 of segment 
length). Paddle as figured; lightly pigmented; 
midrib strongly sclerotized, evanescent apical- 
ly; external buttress distinct proximally; basal 
pigment bar distinct; external margin with 
distinct serrations on apical half; internal mar- 
gin with apical serrations gradually changing 
to larger, poorly sclerotized crenulations at 
about 0.12 from apex; hair 1 slender, elongate. 
Genital lobe extending to 0.22 of paddle, 
with large ventrocaudal patch of spicules. 
Anal segment indistinct; cereal sclerites well 
defined. Male genital lobe (exuviae of allo- 
type, 671-31) extending to 0.22 of paddle; 
pair of large ventral patches of weak spicules; 
anal segment indistinct.
