REVISION OF THE GENUS MYOTROMBICULA
WOMERSLEY AND HEASLIP, 1943
(TROMBICULIDAE : ACARINA) *
BY
P. H. VERCAMMEN-GRANDJEAN **.
The genus Myotrombicztla was created by Woi\ŒRSLEY and HEASLIP in 1943
for a unique specimen of which the remains of the chelostyles, both broken, consisted of the bifid basal articulation accidentally turned upside down and suggesting
to the imagination of any observer, a peculiar modification of the chelostyle for
the purpose of hair clasping (similar to that of fur mites like l\!Iyobiidae or Listrophoridae). Later, it vvas demonstrated that the chelostyles of the members of
this group were very like that of other trombiculids and that the case of Myotrombicula vespertilionis was a simple artifact. Nevertheless, the genus of
WoMERSLEY and HEASLIP proved to be perfectly valid on the basis of several
other characters (V.-G., 1963 a) . In a broad sense it is close to Leptotrombidùtm
s. str., but the leg setation is rather different and the scutum possesses anterolateral shoulders and, sometimes, a pronounced projection placing the anteromargin far before the AM and AL lines, a projection that never exists in Leptotrombidium. The palpai segments are also peculiar in their bony or contorted
outline.
Today the genus Myotrombicula unites four subgenera in a new combination,
as follows : r) Alexfainia, z) Vergrandia, 3) Perates, and 4) Myotrombicztla.
I want to express my gratitude to Dr. D. C. LEE, the Curator of the Acarology
Department of the South Australian Museum, ADELAIDE (S. Australia). Thanks
to his faithful and trusting generosity, I was able to restudy the precious generotype of .111. vespertilionis. I am also indebted to our esteemed colleague, Dr.
J. M. BRENNAN of the Rocky l\!Iountain Laboratory, HAMILTON (Montana, U.S.A.),
for allowing me to see sorne specimens in his extensive collection.

Rem. : The scutal margins are obviously submerged by epiostracal pleats 1 .
After having seen 3 other specimens in the R.M.L., I must admit that the anteromargin is slightly less prominent, and without the rounded shoulders shown in
my drawing of 1964. Nevertheless all the setae are on scutum and not "off scutum ", as stated in the original publication, and the striplike scutum is similar
to that of anophthalma in Perates and bidentipalpis in Myotrombicula s. str. As
for the microtarsala or famulus 2, its knobbed apex matches perfectly with the
similar S 2 in M. olosa.
Perhaps discors pertains more to ll!Iyotrombicula than to Perates, as its branched
galeala also suggests. However, til more links are found, is it probably wiser to
keep it in the latter subgenus. Eye lenses, 2 normal pairs.

Rem. : With its striplike scutum, its biangular palpai contour and its nude
galeala, this species is an important link with anophthalma, discors and macrozota
in the Perates group. However, for the same reason that discors is retained among
the Perates, bidentipalpis will remain in the group Nfyotrombicula s. str. Famulus 2
pointed, not phalliform. Chelostyles with tricuspid cap, no teeth.

Rem. : Scutal anteromargin at 6 fL from AM and 7 p. from AL ; marginal zone
with rare punctations. Sensillae with 6 to 9 long branches (peduncle = 20 fL,
branched distal half = 31 fL, 7 branches) ; scutal setae with thin but conspicuous
barbs, AM >PL >AL. Eye lenses, 2 pairs of normal diameter. Galeala furcate.
Leg setae with few branches. One long barbed seta on dorsum of tarsus 3 can
be taken as a mastitarsala. Dorso-central body setae shorter than the externals or laterals (De>Dc). Famulus 2 pointed. Chelostyles with tricuspid cap,
