DOLICHOCOLON REX SP. NOV. ( FIG. 21A–C View Figure 21 )
Type material: Holotype ♂: Rex Range Lookout /via Julatten, N. Qld./ 9.xi.-2.xii.1981 /Malaise trap// Dolichocolon [ QM].
Etymology: From the type locality Rex Range , a noun in apposition.
Description: Body length: 9.3 mm.
Coloration and pruinescence: Head mainly black, covered with whitish-grey pruinescence. Palpus brownish basally, shading into yellow distally. Scape and pedicel blackish-brown. Thorax mainly black; scutellum largely reddish-yellow; scutum with four presutural dark vittae, lateral vitta distinctly outlined and ending wedge-shaped beside posthumeral seta. Legs black. Tegula and basicosta black to dark brown. Abdominal tergites 3 and 4 with a transverse band of whitish-grey pruinescence (without shifting spots) on anterior 2/3-4/5; tergite 5 entirely covered with pruinescence; remaining posterior surface of tergites 3 and 4 covered with brownish-bronze pruinescence. Abdomen entirely black in ground colour.
Head ( Fig. 21A View Figure 21 ): Compound eye with a few sparse and very short ommatrichia at most as long as diameter of one facet (visible under> 50 ¥ magnification). Arista thickened on basal 1/2. Second aristomere 7.1 times as long as wide. Thickened part of third aristomere 0.9–1.0 times as long as second aristomere. Postpedicel 6.9 times as long as pedicel. Vertex at its narrowest point 0.98 times as wide as compound eye in dorsal view. Lateral vertical seta slightly differentiated from postocular setae; postocular setae relatively long and bent anteriorly. Ten to 11 frontal setae descending below level of base of arista. Frontal vitta (measured at midlength between fore ocellus and base of antennae) 1.2 times as wide as fronto-orbital plate (measured at same level). Fronto-orbital plate with one row of medioclinate setae lateral to row of frontal setae. Gena in profile 0.2 times as high as compound eye. Prementum about 1.0–1.5 times as long as wide.

Abdomen: Syntergite 1 + 2 without median marginal setae. Tergite 3 with pores of one pair of small median marginal setae (setae broken off). Tergite 4 with a row of ten marginal setae shorter than corresponding tergite. Tergite 5 with a row of marginal and discal setae.
Male terminalia ( Fig. 21B, C View Figure 21 ): Epandrium short and convex, but not globular ( Fig. 21B View Figure 21 ). Hypandrial apodeme, in lateral view, longer than hypandrial arm. Surstylus stout, distal 1/3 strongly bent posteriorly, dorsal surface of distal 1/3 not concave ( Fig. 21B, C View Figure 21 ). Posterior and lateral surface of surstylus covered with short setae ( Fig. 21C View Figure 21 ). Medial sclerite of surstylus not visible in lateral view. Basal 2/3 of cerci prominent and subrectangular in lateral view; distal 1/3 strongly bent posteriorly and widened apically. Cerci, in posterior view, as in Figure 21C View Figure 21 .
Hosts: Unknown.
Distribution: Australasian: Australia (northern Queensland).
