Legs short, robust, fore femora heavily incrassate for middle 2/3 area, more narrowed at base than at apex, in apical ½ ventrally armed with spines, in 2 indistinct series, inner series with 1or 2 large and several minute spines, and outer series with 2 large and several minutes spines.

Sternites I–III fused; trichobothria with middle one on sternite III slightly behind other two and almost linear on sternite IV (Fig. 1d).
Male genitalia: Pygophore as in Fig. 2a; paramere with dorsal and ventral lobes, and blade sickle-shaped as in Fig. 2 b–e; aedeagus as in Fig. 2f, g.
Etymology: The species name Latin “ spectabilis ” adjective, alludes to this insect’s remarkable and showy general facies.
Distribution. Little Desert National Park, Victoria, Australia.
Notes. The only two specimens available of this species, and the udeocorine Laryngodus luteomaculatus Slater, Schuh, Cassis, Johnson & Pedraza-Penalosa (Figs. 3, 4), were found to occur sympatrically at the Little Desert National Park, Victoria. However the former species was collected associated with Myrtaceae: Melaleuca wilsonii F. Muell., (Violet honey-myrtle), while the latter species, widely distributed in South Australia and Victoria, with Casuarinaceae: Allocasuarina pusilla (Macklin) L. A. S. Johnson. (Slater et al. 2009).
