Figure 22, map 6, table 1, plates 6, 7, 43D, E

DIAGNOSIS: Recognized by black pygophore contrasting with pale remainder of abdomen, black antennae and black legs, and fuscous markings on the vertex, pronotum, and scutellum (pl. 6); endosoma with a very long, erect, sinuous, apical spine and a second, shorter subapical spine with two or three strong points (fig. 22, pl. 7). Tubular body and black pygophore contrasting with remainder of abdomen also seen in Telophylus eremophilae , but that species with all legs entirely pale and antennae not entirely black, secondary gonopore with medial flanking crest, and endosoma with apical microtrichiate plates diagnostic for Telophylus ; endosoma in D. halganii without flanking crest near secondary gonopore or microtrichiate plates apically.

DESCRIPTION: MALE: Mean total length 3.01, mean pronotum width 0.73. COLORATION (pl. 6): Background color pale to weakly infuscate, vertex medially, much of pronotum, scutellum medially, claval suture, and corium adjacent to inner angle of cuneus infuscate to dark brown; clypeus, antennae, thoracic pleuron, legs, and pygophore black; abdomen sometimes infuscate, but not black. SUR- FACE AND VESTITURE (pl. 6): Dorsum smooth, weakly polished and weakly shining, venter dull; dorsum clothed with reclining, pale, simple setae of moderate length. STRUCTURE: Head (pl. 6): As in generic description, but antenna inserted above ventral margin of eye by about diameter of antennal fossa; antennal segment 2 relatively short (0.68), 1.28 times width of head. Thorax (pl. 6): As in generic description. Hemelytron: As in generic description. GENITALIA (fig. 22, pl. 7): Pygophore: Broadly conical, posterior margin indented ventrad of left paramere insertion. Endosoma: J-shaped, basal fusion of straps on dorsal side; strap without proximally directed spine, ventral edge of strap with very long, erect apical spine; dorsal edge of strap with three pointed subapical spines (points); endosoma subapically expanded with membrane conforming to endosomal surface; secondary gonopore situated just distad of middle of endosoma on margin of projecting strap. Phallotheca: Posteroventral surface of apical portion with dispersed field of denticles, dorsal edge strongly crested without spicules; anterodorsal surface not serrate; aperture ovoid and compressed, anteromedial edge with notch. Parameres: Left paramere with dorsoposterior margin faintly undulate, not produced dorsad of posterior and anterior processes; posterior process straight; anterior process large and rounded apically; prominent seta placed apically; right paramere with short anteroapical projection.

FEMALE (pl. 6): Coloration as in male; structure as in generic description; mean total length 2.32, mean pronotum width 0.70. GENITALIA as in plate 43D, E.
