Oteana tattendi
: A habitus; B, C, D head.
Oteana sponsa
: E habitus; F, G, H head.
Etymology
The name is based on ‘tattendi’, which means ‘to ascend, climb up, to go towards’ in Kaurna, an aboriginal language in
South Australia
(
Thieberger & McGregor 1994
) and refers to the ascending (caudally directed) spines on the phallotheca.
Colour
Head light to mid brown, carinae paler; pronotum light brown; mesonotum mid to dark brown, paler between lateral and sublateral carinae; legs light brown; forewing hyaline colourless with brown marks along crossveins, veins light brown, apically darker, tubercles indistinct, concolorous with veins, pterostigma light brown; abdominal sternites light brown.
Morphology
Body length:
♂
6.3–7.6 mm
,
♀
8.3–8.8 mm
.
Head: Vertex (total length) 1.5–1.9 times longer than wide; basal emargination obtusely angled or rectangular. Postclypeus with welldeveloped median carina. Rostrum not reaching hind coxae.
Thorax: Hind margin of pronotum obtusely angled. Mesonotum with evanescent or welldeveloped carinae. Forewing 3.0–3.3 times longer than wide; costa with 0–1 tubercles; 9 (rarely 8) apical cells.
Male genitalia: Anal tube as in
Figs 48H–J
; pygophore and genital styles as in
Figs 48K–L
. Aedeagus (
Figs 48M–N
): Phallotheca with a long spine (a); a long spine (b) forking into a strong branch (b1) and a slender branch (b2); a short spine (c); and a slender spine (d). Flagellum membranous, unarmed.
Remarks
In the male genitalia of some specimens, branch (b1) is reduced to a small knob as in
Fig. 48O
. It is possible that these specimens once possed branch (b1), but it broke off at some stage in their life (perhaps during copulation). Because the significance of this variation is unclear, these specimens have been excluded from the
type
series of
Ot. tattendi
.
