Type material
Syntypes
(examined),
AUSTRALIA
, VIC
:
3 ♀
,
Melbourne
, on apple trees (
BPBM
)
.
Morphology
Body length:
♀
6.1–6.3 mm
.
Head: Vertex (total length) 1.1 times as long as wide; lateral carinae slightly elevated; basal emargination obtusely angled. Lateral carinae of frons convex (rectilinear apically). Rostrum reaching hind coxae.
Thorax: Hind margin of pronotum obtusely angled. Mesonotum with welldeveloped carinae. Forewing 3.4 times longer than wide; fork ScRA+RP distad of fork CuA1+CuA2; rm crossvein basad of fork MA+MP; RP apically bifid; MA apically trifid; MP apically bifid; costa with 0–19 tubercles; 9 apical cells. Hind leg: tibia with 3 lateral spines; 6 large apical teeth; 1
st
and 2
nd
tarsomere with 7 apical teeth and no platellae.
Male genitalia: Unknown (only known specimens are females).
Remarks
Muir (1925)
placed this species in
Oliarus
sensu
lato
which at that time accommodated most of the
Pentastirini
species worldwide. As discussed in the introduction, several authors have since split the
Oliarus
sensu
lato
complex into a number of smaller genera. Three new genera for the Australian fauna are proposed in this study.
Prosops
closely resembles
Ozoliarus
gen. nov.
in having 3 lateral spines and 6 large apical teeth on the hind tibia and 7 apical teeth on the first and second tarsomere, and may in fact be congeneric with it. Because of the poor quality of the type specimens (microscope slides in very bad condition) and the original description, important features such as the carination of the head cannot be investigated. The
syntypes
are females, which makes it impossible to match them reliably with other Australian species based on male genitalia.
Prosops pedisequus
was described as “the apple tree destroyer” (
French 1909
). Cixiids, however, are currently not known to be pests on apples in
Australia
(pers. comm. Graham Thwaite, 2005) and investigation of the Australian
Pentastirini
material failed to discover any specimens collected on apple trees (except for the
syntypes
). Therefore
Prosops pedisequus
is regarded as a
nomen dubium
. If at some stage it is confirmed that
Prosops
is congeneric with
Ozoliarus
,
then the name
Prosops
will have priority over
Ozoliarus
.
Prosops pedisequus
differs from
Cordoliarus
in the shape of the head, from
Oteana
in the presence of 7 apical teeth on the 2
nd
tarsomere, from
Oliarus
sensu
stricto
as proposed herein in the presence of three lateral spines on the hind tibia and 7 apical teeth on the 2
nd
tarsomere, and from species of
Miclucha
in the number of apical teeth on the hind legs/and or shape of the areolets.
