Austrotinodes bibu
sp. nov.
Figs 25–27
Diagnosis.
Austrotinodes bibu
can be separated from other group members as the dorso-basal processes near base of the inferior appendages (phallic guides) are relatively straight, and the inferior appendages are slender, with length about 4 times width. This species is somewhat atypical of this group and shares some of the characters of the
A. varus
and
A. yalga
groups.
Description.
Head, body and wings brown; wings similar to
A. yalga
(
Fig. 14
). Forewing length about 3.1–3.3 times width: male
5.3 mm
. Forewing fork 2 long, with footstalk, footstalk length about twice length of cross-vein r-m, length fork about same length as fork 3; fork 3 long, length about 1.9 times length footstalk, footstalk length about 2.8 times length cross-vein m. Hindwing length about 3 times width; fork 2 footstalk length about 1.7 times length cross-vein r-m, fork length about same length of fork 3.
Male. Tergum X membranous with a pair of small mesal processes (
Fig. 27
). Superior appendages in lateral view, tapered gradually apically, length about 2.5 times width, with pair of short ventral processes with short apical hairs (
Fig. 25
); in dorsal view, robust, length about 2 times width, with small subapico-mesal process (
Fig. 27
). Phallus robust, generally tube-like, with embedded pair of long spines; with a pair of straight, slender processes (phallic guides) arising from near the base of the inferior appendages (
Fig. 25
). Inferior appendages in ventral view, slender, paired processes, length about 4 times width, bases widely separated (
Fig. 26
); in lateral view, length about twice width, with pointed apex (
Fig. 25
).
