ABSTRACT
- The rediscovery of Tenuipalponychus tabebuiae Aguilar, Flechtmarm & Ochoa is
reported and is redescribed from the Brazilian type material and additional specimens from Costa Rica.
INTRODUCTION
Flechtmann (1971), in his unpublished thesis,
described Tenuipalponychus tabebuiae under the genus
Tylonychus collected from an unidentified species of
Bignoniaceae in Brazil. As it was inadequately
described, with a few illustrations and the host plant
was unidentified, we decided to redescribe this species.
It is based on the type material from Brazil and
specimens collected in Costa Rica.
Since the dorsal integument of T. tabebuiae is
mostly reticulate with a few transverse striae, the fourth
pair of dorsocentral setae is in a rather marginal posi-
tion and the humeral setae are well separated from the
dorsolateral setae and located on the body margin, this
species rather belongs to the genus Tenuipalponychus
Channabasavanna & Lakkundi (1977). All measure-
ments are given in micrometers.
Tenuipalponychus tabebuiae Aguilar, Flechtmann &
Ochoa
(Figs. 1- 17)
Tylonychus tabebuiae Flechtmann, 1971: 45-46,
unpublished name according to ICZN, chapter 3.
FEMALE (Figs. 1 - 8) : Specimens examined and
measured - 6 females from the type series, from Brazil,
and 7 females from Costa Rica, both from Tabebuia
ochracea (Cham.) Standley, Bignoniaceae.
Length of body, including gnathosoma, 371 (338-
416); width 253 (221- 286). Stylophore rounded, with a
median indentation on its anterior border. Peritremes
hooked distally. Terminal eupathidium (su) of palpus
thick, strong, about twice as long as its greatest width.
The palptarsus also bears eupathidia (ul' and ul") which
are
subequal in length, solenidium (w) relatively long
and of 3 simple setae.
Dorsum of idiosoma with 13 pairs of strong, rod-
shaped, serrated setae, longer than longitudinal inter-
vals between their bases; all set on strong tubercles.
Dorsal integument mostly finely reticulate, with a few
transverse striae. Eyes barely visible, associated with
the tubercle bearing setae P2 (Sc 1).
Legs as figured in Figs 4-7; chaetotaxy: coxae 2-2-
1-1; trochanters 1-1-1-0; femora 3-3-2-0; genua 4-3-2-2;
tibiae 6-5-3-2. Tarsi as illustrated. Empodia uncinate,
a simple clawlike structure; true claws padlike, with
tenent hairs.
MALE (Figs. 9 - 17) - Specimens examined and
measured: 5 males from the type series and 4 specimens
from Costa Rica.
Length of body, including gnathosoma, 400 (325-
494). Terminal eupathidium of palptarsus small, about
as long as wide; palptarsus also with 2 inequal
eupathidia, a longer solenidion and 3 setae.
Idiosoma with dorsal setae strong, serrate, those
of pair P2 (Sc 2), L 1 (c 2), L 2 (d 2) and L 3 (e 2)
longest, much longer than intervals between their bases.
Legs about twice as long as idiosoma. Chaetotaxy:
coxae 2-2-1-1; trochanters 1-1-1-1; femora 6-6-4-3;
genua 5-4-3-3; tibiae 10-7-4-4. Tarsi as figured. Em-
podia a simple clawlike structure.
Aedeagus straight, elongate, with a narrow long
tip. Flanking the aedeagus and somewhat ventral to it,
one pair of stylets, probably guiding structures. In one
specimen the tube extending from the male reproduc-

the other damaged after running for a short distance.
DIAGNOSIS
T. tabebuiae
is the second species in the genus
Tenuipalponychus;
it is easily separated from the type
species, T.
cirri
Channabasavanna & Lakkundi by the
longer dorsohysterosomal setae: longer than lon-
gitudinal intervals between their bases, and tapering in
T. tabebuiae (
shorter than longitudinal intervals be-
tween their bases and blunt in T. citr/).
REMARKS
Attacked leaves of
Tabebuia ochracea
in Costa
Rica displayed a light punctate chlorosis. Some lower
leaves were yellow.

The following families are represented: Eriophyidae, Tarsojnemidae, Pyemotidae, Scutacaridae, Podapolipodidae, Tydeidae, Tetranychidae, Tenuipalpidae, Raphignathidae, Stigmaeidae, Caligonellidae, Cryptognathidae, Cheyletidae, Pterygosomidae and Pseudocheylidae.
Article
Formerly only four species of the family Tetrany-chidae had been recorded from Tasmania. Collec-tions of mites from both introduced and native plants have revealed that the family is represented by ten genera of which two are new. Fifteen species, five being new, are now recorded from the State. The following new genera and species are des-cribed:-New genera-Synonychus, Tylonychus. New species-Synonychus eucalypti, Eutetrany-chus acaciae, Tylonychus tasmaniensi!s, Eotetranychus hudsoni and Tetranychus rhagodiae. In addition the male of Schizonobia sycophanta Worn. is described for the first time.
