MATERIAL EXAMINED:
U.S.A.
,
New Mexico
, on “
Atriplex
,”
11. i. 1897
,
Townsend
coll., deposited at
USMN
: 1/2 ad males (in good condition but uncleared, description of specimens based on confocal microscope images and thus some pores and setae not observable and mentioned as such)
.
DIAGNOSIS:
Orthezia annae
differs from other
Orthezia
spp. in having additional longer antennal setae, some on legs, similar to those on antennal setae, and fewer tubular ducts than on other
Orthezia
spp.
DESCRIPTION (as for family description unless otherwise stated):
Mounted material:
Body large, total body length
1.5–1.65 mm
. Antennae 1.3 times total body length, most segments subequal in length;
fs
present on antennae.
Head:
Width
300 µm
, length
250 µm
. Dorsally, dorsomedial part of epicranium, with at least 4 or 5
hs
;
lp
and
smp
not observable. Laterally, compound eye about
115 µm
long, with about 100 ommatidia; ocelli
23–30 µm
wide. Ventrally, ventromedial part of epicranium, with ventral head sclerotized lateral margins; setae and pores not observable.
Wings:
Forewing 1.9–2.0 µm long, about
638–796 µm
wide (ratio of length to width 1:0.37; ratio of total body length to wing length 1:1.23), base of wing especially narrow, with subcostal ridge extending to less than ¾ of wing length; cubital ridge starting 1/8 of wing base; without alar setae; circular sensoria along posterior margin of subcostal ridge detected, but number unclear; sensoria extending to ¾ of wing length to where subcotal ridge disappears. Hamulohaltere
225 µm
long,
30 µm
wide; with 2 apical hamuli each
55 µm
long.
Legs:
Leg setae
13–20 µm
long but with additional, significantly longer,
fs
ventrally on femur and tarsus, and on both sides of tibia (
30–40 µm
long). Coxae: I 124–147; II 120–152; III
131–140 µm
long; coxa III with at least 4 setae. Trochanter + femur: I 473–506; II 374–411; III
608–704 µm
long; trochanter III with about 3
hs
; each trochanter with 3 campaniform sensilla arranged in a line on each side; femur III with about 35 short setae + 4–6 long setae ventrally; also 7 or 8 longer
fs
on ventral side of femur among shorter setae. e I 585–649; II 527–562; III
608–704 µm
; tibia III with a total of about 100 setae including long setae on both sides of tibia; each distal spur
23–25 µm
long. Tarsi: I 164–193; II 142–180; III
148–214 µm
long (ratio of length of tibia III to length of tarsus III 1:0.26); tarsus III with about 23–30 spurlike setae and 2 or 3 long setae ventrally; tarsal digitules very short and setose. Claws fairly long and thin, much longer than width of tarsus (each tarsus about
15 µm
long), held at a distinct angle to tarsus, each with 1 small denticle; length: III
40 µm
; claw digitules both short and setose.
Abdomen:
Segments I–VII:
Setae and
lp
detected on pleurites (number unknown) but not observable on sternites and tergites. Tubular ducts present in a band of about 20 ducts across tergite VII, each duct
10 µm
wide,
20 µm
deep. Abdominal spiracles present on anterodorsal part of at least pleurites II–VII.
Segment VIII:
tergite with 1 or 2 pairs of
hs
dorsal abdominal setae, small locular pores numerous, but exact number unknown; sternite with at least 6 setae (probably more but not observable) but no pores; margin rounded, with 2–4
hs
pleural setae. With a pair of abdominal spiracles similar to those on more anterior abdominal segments.
Genital segment:
Anus large (
40 µm
wide). Penial sheath as broad as posterior margin of abdominal segment VIII, short, triangular, and blunt; length without segment IX
220 µm
, with segment IX
281 µm
; greatest width
140 µm
; ventrally and laterally with a group of about 15 long
hs
(each
45 µm
long) on each side of anterior end of penial sheath.
COMMENTS: Despite the lack of resolution for some setae and pore distribution,
O. annae
is particular for the presence of longer setae on the legs (fig. 7), among the setae present in other
Ortheziidae
species.
