As can be seen from the list of generic placements above, this species has had a confused taxonomic history.
Brunetti (1917)
originally described the species in
Empidideicus
. However, the illustration of the wing venation in the original description depicting a distinct small triangular marginal cell precludes it from being a member of that genus. Subsequent treatments of the species by Bezzi had it questionably in
Cyrtosia
(1925)
and later (1926) in
Glabellula
.
Bowden (1975)
, apparently unaware of Bezzi’s (1926) earlier placement of the species in
Glabellula
, also placed
indica
in that genus with the notation “N. comb.” Bezzi’s and Bowden’s placement in
Glabellula
were undoubtedly due to the presence of the small triangular marginal cell in the wing. The only known Old World genus in
Bombyliidae
at the time of Bezzi’s and Bowden’s placement that possessed such a cell was
Glabellula
. However, the remainder of the wing venation (see
Fig. 14
) does not match
Glabellula
. The original description is quoted here.
Female
. “Frons apparently about onefourth the width of the head, yellowish; antennae black; proboscis more than 1 1/2 times height of head.
Thorax
black, practically bare; humeri bright yellow;
Abdomen
black, hind margins of segments pale yellow, and a yellow transverse line across middle of 1st and 2nd segments.
Legs
black, knees and tips of tibiae yellowish.
Wings
pale grey; auxiliary vein short, ending free: 1st vein ending at middle of costa; praefurca beginning at middle of 1st vein; 2nd vein very short, directed abruptly upwards, ending in 1st vein near tip; 3rd vein in line with praefurca, simple, ending a little before wing tip; 4th vein forked at half its length after quitting basal cells, the portion dividing those cells hardly less distinct; 5th forked, base of upper branch forming lower side of 2nd basal cell; 6th vein reaching wing border. First basal cell a little longer than 2nd; bifurcation of praefurca opposite tip of 2nd basal cell.
Length
1 mm

Male
. Unknown.
Types
.
Brunetti (1917)
originally described this species based on “four
paratype
specimens in the Indian Museum in very indifferent condition taken by Dr. Annandale at Simla,
7,000 ft
.” Only 2 of these
4 specimens
could be found in NZSI. One of the 2 surviving specimens has the head missing. The specimen with the head intact is designated here as
lectotype
female to stabilize the nomenclature of the species. The indication of the
type
of
Empidideicus indicus
as a
holotype
in
Evenhuis (2002b: 36)
was in error.
Remarks
. No specimens other than those from the original
type
series are known. Despite the lack of specimens for examination, the original description and accompanying illustration of the wing give enough evidence of salient characters to show that it belongs to
Mythenteles
. Along with
M
.
hispanicola
,
M
.
infrequens
,
M
.
coptopheles
, and
M. wadimurri
, this species lacks crossvein dmcu.
Distribution
. Known only from the
type
locality in Simla,
India
.
