Gynoplistia (Gynoplistia) kennedyi nov.sp. ( Figs 1-8 )

T y p e m a t e r i a l: Holotype ♂: Victoria, Morwell National Park, Fosters Gully (38.3574°S, 146.3880°E), 11-i-2014, Z. Billingham; NMV (MVT21938).

D e s c r i p t i o n

Male ( Fig. 1 )

H e a d ( Fig. 2 ). Dark blackish grey; mouthparts blackish brown. Antenna 16 segmented, pectinate; basal two flagellomeres bearing mesoventrally directed extensions, following 10 flagellomeres bearing dorsally directed extensions, final two flagellomeres lacking extensions; scape, pedicel, and basal two flagellomeres, except for the extensions, yellowish brown, otherwise blackish brown.

T h o r a x ( Figs 3-5 ). Pronotum brownish yellow dorsally. Prescutum yellowish brown anteriorly and laterally, darkening dorsally to form two indistinct brownish black bands extending from just beyond the anterior margin to the prescutal suture. These bands continuing onto the scutum and terminating at the transverse suture, remainder of scutum brownish with anterolateral angle paler yellowish brown. Scutellum yellowish brown. Mediotergite yellowish brown anteriorly, darkening to brownish black posteriorly. Cervical sclerite brownish. Propleuron brownish yellow. Anepisterunum and katepisternum brownish black. Anepimeron brownish yellow. Katepimeron brownish yellow anteriorly, darker brown posteriorly. Meron brownish yellow, fringed basally with darker brown. Laterotergite brownish black. Metanepisternum brownish. Metakatepisternum brownish. Coxae, trochanters and proximal 4/5 of femora brownish yellow, distal 1/5 greyish black; tibiae with narrow proximal brownish yellow ring, tibia 1 and 2 otherwise greyish black, tibia 3 with middle 1/3 white, remainder greyish black; tarsi greyish black.

W i n g ( Fig. 6 ) with pale-dark pattern; costal and subcostal cells greyish black; pterostigma dark greyish black; apex and posterior margin infuscated, apex especially so; three dark brownish grey marks present: just distal to MA, at origin of Rs and at the fork of Rs; paler brownish grey markings at the origin of M1 and M2, along m-m and m-cu, and at 2/3 and 1/2 the length of A1 and A2 respectively. Halter with stem brownish yellow, knob brownish black.

A b d o m e n. Brownish yellow, greyish black on lateral and posterior margins of tergites 1-7, segment 8 and 9 brownish black.

G e n i t a l i a ( Figs 7, 8 ). Hypopygium with hind margin of segment 9 dorsally broadly truncate, almost widely bilobed, ventrally with wide, deep V- to U-shaped excision. Gonocoxite with medio-ventral, thumb-shaped, backward-directed, setose process. Outer gonostylus rather strongly curved with apex sharply pointed; inner gonostylus S-curved with apex rounded. Aedeagal complex with two lateral elements close to each other, both short, strongly curved and with apex pointed, and a medium-shouldered medial element (aedeagus).

D i m e n s i o n s. Wing length 8.0 mm; body length (excluding antennae) 9.5 mm.

Female unknown. E t y m o l o g y. This species is dedicated to Kennedy (Ken) Harris who assisted in the collection of the type material and who has assisted greatly in the first author’s studies of Australian crane flies.
