Culicoides owyheensis
Jones and Wirth
Culicoides owyheensis
Jones and Wirth, 1978: 57
(misspelled as
owyheenis
; key; female;
Idaho
).
Wirth et al. 1985: 36
(numerical characters; fig. female wing).
Diagnosis.
(
Tables 14
,
15
,
17
,
18
) Brown with some yellow; wing without pattern of pale spots (as in
Fig. 3
C
.
stonei
); two sclerotized ovoid spermathecae and fingerlike vestigial third (as in
Fig. 45
C
.
stonei
); posterior portion of female sternite 8 cleft, with blunt submedian posterior projections (as in
Fig. 45
C
.
stonei
); ventroposterior membrane of male sternite 9 spiculate; aedeagus Y-shaped, median process stout, short, blunt, half as long as basal arms; parameres separate, simple, apex curved hooklike (as in
Fig. 41
C
.
mortivallis
). To distinguish from
C
.
mortivallis
, ratios to length of flagellomere 9:>1.50 for flagellomeres 7+8,>3.95 for proboscis,>1.90 for palpal segment 3.
Distribution.
Idaho
(Owyhee County),
Utah
(Grand County).
Adult behavior.
R. H. Jones and H. W. Potter Jr. collected females from the ear of a sheep prostrate with bluetongue in
Idaho
(
Jones and Wirth 1978
). However, I think that
C
.
owyheensis
may be a junior synonym of
C
.
mortivallis
, and the record may be for that species.
Remarks.
Using the measurement ratios from Wirth and
Jones (1978: 57)
, 2 of
17 specimens
recognized as either
C
.
owyheensis
or
C
.
mortivallis
based on SCo pattern were identified as
C
.
owyheensis
(
Table 18
). See also Stonei group discussion.
