Diagnosis.
This species is morphologically very similar to
D. kelleri
Fagan-Jeffries, 2019
, but clearly distinct using both
COI
and
Wingless
DNA barcodes. In the specimens currently available, it can be differentiated by T3 with only sparse setae in the anterior half (
D. kelleri
with T3 regularly setate over whole length).
Of the Australasian species without sequence data, this species most closely resembles
D. miris
, and can be separated from it by T2 smooth and shining (T2 shallowly sculptured in
D. miris
) and by flagellomere 14 slightly longer (antennal flagellomere 14 length/width 1.6 – 1.7, whilst in
D. miris
flagellomere 14 length/width approximately 1.2).
Dolichogenidea franklinharbourensis
can be separated from the remaining Australasian
Dolichogenidea
species in the following ways:
• From
D. biroi
(
Szepligeti, 1905
)
,
D. ilione
(
Nixon, 1967
)
,
D. lipsis
(
Nixon, 1967
)
,
D. tasmanica
(
Cameron, 1912
)
by the absence of a white gena blotch.
• From
D. acratos
(
Nixon, 1967
)
,
D. brabyi
Fagan-Jeffries & Austin, 2019
,
D. eucalypti

,

)
,
D. forrestae

,
D. garytaylori

,
D. hyposidrae
(
Wilkinson, 1928
)
,
D. orelia
(
Nixon, 1967

by having ovipositor sheaths of similar length to the metatibia (all species listed here have ovipositor sheaths significantly shorter than metatibia).
• From
D. coequata
(
Nixon, 1967
)
,
D. cyamon
(

)
,

D. platyedrae
(

)
,
D. xenomorph
Fagan-Jeffries & Austin, 2018a
by having ovipositor sheaths of similar length to the metatibia (all species listed here have ovipositor sheaths significantly longer than metatibia).
• From
D. bonbonensis
Fagan-Jeffries & Austin, 2019
,
D. lobesiae
Fagan-Jeffries & Austin, 2019
by having a clearly differentiated white patch on the proximal third of the pterostigma.
• From
D. agonoxenae
(
Fullaway, 1941
)
,
D. carposinae
(
Wilkinson, 1938
)
,
D. gentilis
(
Nixon, 1967
)
,
D. heterusiae
(
Wilkinson, 1928
)
by having T2 completely smooth.
• From
D. hyblaeae
(
Wilkinson, 1928
)
,
D. inquisitor
(
Wilkinson, 1928
)
,
D. iulis
(
Nixon, 1967
)
,
D. stantoni
(Ashmead, 1904)
by the absence of a complete areola in the anterior half of the propodeum.
•
D. upoluensis
(
Fullaway, 1941
)
, reared from a leaf-mining caterpillar on
Ficus
in
Samoa
, was described from a single male specimen, which was unable to be examined. Despite being unable to examine the
holotype
, we feel that
D. upoluensis
is highly unlikely to be the same species as that described here. Fullaway’s character, the “first tergite…a little wider at apex than at base, the sides then hardly parallel though straight” (
Fullaway, 1941
) could possibly be used to differentiate the species, as
D. franklinharbourensis
has T1 parallel sided.
Description.
FEMALE. Colour. Head, antenna and mesosoma all dark; all tergites and most of metasoma dark, non sclerotised areas of T1–2 and anterior sternites dark (but paler than sclerotised areas of dorsal tergites); hypopygium dark laterally and mostly dark ventrally, ovipositor sheaths dark; (fore-, mid-, hind coxa) dark, dark, dark; (fore-, mid-, hind- trochanter) all transitioning from dark to pale; femora (fore-, mid-, hind femur) mostly pale (in
paratype
, missing in
holotype
), pale with dark line along length, mostly dark with pale area at proximal end; tibiae (fore-, mid-, hind tibia) mostly pale (in
paratype
, missing in
holotype
), pale, pale transitioning to dark distally; hind tarsi light brown, all paler proximally than distally; tegula and humeral complex dark; pterostigma dark with small pale patch proximally; fore wing veins dark.

Anterior head.
Body length. Head to apex of metasoma:
2.8 mm
.
Head. Antenna approximately equal to body length; OOL/POD 1.9 (2.2); POL/ POD 2.7 (2.5); antennal flagellomere 2 length/width 2.7 (2.5); antennal flagellomere 14 length/width 1.6 (1.7).
Mesosoma. Anteromesoscutum relatively smooth and shiny, shallowly and regularly punctate; number of pits in scutoscutellar sulcus 12 (13); scutellar disc very smooth and shiny, with only shallow pits associated with setae; maximum height of mesoscutellum lunules/maximum height of lateral face of mesoscutellum 0.6. Propodeal areola clearly differentiated in posterior half of propodeum, with lateral carina clearly visible. In anterior half, areola only differentiated by denser sculpturing than surrounding area. Rest of propodeum mostly smooth and shiny with scattered punctures concentrated in the anterior third.
Wings. Fore wing length 3.0 mm; length of veins r/2RS 1.3; length of veins 2RS/2M 1.4; length of veins 2M/(RS+M)b 1.1; pterostigma length/width 2.8 (2.4).
Legs. Hind tibia inner spur length/hind basitarsus length 0.4.
Metasoma. T1 length / T1 width at posterior margin 1.1; parallel sided, reticulate rugose sculpturing in posterior half with some areas verging on strigose, smooth area in posterior centre, T2 width at posterior margin / T2 length 3.8 (4.2), short and wide with curved lateral sides, very smooth, border with T3 very subtle, only very shallowly indented; T3 sculpture smooth and shiny with scattered setae concentrated in lateral posterior corners; ovipositor sheaths length/hind tibial length 1.1; ovipositor sharply angled approximately 45 degrees below the horizontal in the posterior third.
MALE. Unknown.
Etymology.
This species is named by the 2020 Year 4/5 class of students of Cowell Area School, after the collection locality of the
type
specimen and the district where the school is located. The species epithet is an adjective.
Distribution.
This species is only known from
South Australia
, from one locality on the Eyre Peninsula and one locality in the central arid regions near Lake Torrens.
Host.
Unknown.
