Diagnosis
: Head and thorax covered in conspicuous hairs (
Figs 21
,
64
). Head as broad as or broader than thorax; vertex rectangular to trapezoidal; genal processes with the outer margin straight and the inner strongly convex from above; occipital sclerite may be developed as a tubercle; lateral ocelli raised on tubercles close to posterior margin of eye; anteorbital tubercles present (
Fig. 21
). Antenna 1.2–2.2 times the head width; segments 9 and 10 broader; setae on antennae longer than width of segments; segment 3 the longest; segment 10 longer than 9. Forewing somewhat rectangular, broad to very elongate; veins bearing prominent setae much longer than the diameter of veins; Rs long and sinuous; vein M1+2 strongly arched upwards; rs-m crossvein occasionally present; C+Sc and pterostigma somewhat thickened; costal break present. Meracanthus prominent; metatibia without genual spine and with a crown of 8–14 apical spurs; metabasitarsus with 2 apical spurs. Male proctiger densely hairy with broad posterior lobes.
Biology and damages:
Tuthillia cognata
Hodkinson, Brown & Burckhardt
represents a major pest in plantations of
Myrciaria dubia
, also known as camu-camu (
Couturier
et al.
1992
). Damage includes curling of apical leaves which turn yellow and wither (
Burckhardt & Couturier 1988
), dessication of buds and terminal leaves preventing plant growth (
Couturier
et al.
1992
); immatures are found inside the leaf-curls producing great amounts of waxy secretions (
Burckhardt & Couturier 1988
).
T. myrcianthis
Burckhardt, Queiroz, Marsaro Junior & Wyniger
induces irregular blister galls on the adaxial surface of fresh leaves of
Myrcianthes pungens
. Inside the gall a colony of immatures develops which are covered in long threads of wax (Burckhardt
et al.
2012). Specimens of
Tuthillia latipennis
Hodkinson, Brown & Burckhardt
were collected in
Colombia
on
Myrcianthes
sp. whose leaves presented deformations as shown in
Fig. 74
; immatures were found in groups confined to those deformations, covered with threads of wax (field observation).
Host-plants:
Myrtaceae
(Burckhardt & Queiroz 2012; Burckhardt
et al.
2012; NHMB data).
Distribution:
Central
and
South
America (
Hodkinson
et al.
1986
).
Remarks:
This is the first record of this genus in
Colombia
.
