Diagnosis: This species is similar to its congener in both appearance and genitalic structures, but can be distinguished by the following characters: usually larger body size, c. 7.0 mm (usually smaller, c. 5.4 mm in the new species Austrophaeogala ovipennis); elongate, nearly parallel-sided, long oval body shape (Fig. 3D, F) (pear-shaped body, widened posteriorly in A. ovipennis; Fig. 3G, I); slightly thinner body (Fig. 3E) (slightly thicker body; Fig. 3H); more elongate elytra (broader and stouter in A. ovipennis); pubescence on body surface slightly sparser and shorter (Fig. 3D, F) (slightly denser and longer in A. ovipennis; Fig. 3G, I); mesocoxal cavities completely laterally closed (Fig. 7A) (slightly open in A. ovipennis; Fig. 7B); sex patch with setae more decumbent (Fig. 7C) (more erect in A. ovipennis; Fig. 7D); distribution: mainly New South Wales (mainly North Queensland in A. ovipennis).
Description: Body length: 4.7–8.5 mm (6.6 in holotype); width: 1.4–3.0 mm (2.2 in holotype).
Male (Fig. 3D, E). Body long oval, nearly parallelsided; body brown to blackish brown, colour of antennae, maxillary and labial palps and legs lighter; surface sparsely covered with short, fine yellowish setae, setae on dorsum slightly longer than ventral side.
Head (Fig.6A) subquadrate, with frontoclypeal region (Fig. 6B) distinctly depressed and vertex moderately convex, frontal furrows shallowly depressed; surface semilustrous, coarsely and densely punctate, with fine, sparse, decumbent yellowish setae. Compound eyes small, globular and prominent, protruding laterally, ratio of eye diameter to interocular space 1:4.0. Clypeus short, flat, broad, distal margin truncate, with some yellowish setae on the distal margin of the disc. Apical maxillary palpomeres (Fig. 6C) elongate securiform. Apical labial palpomere (Fig. 6D) oval, subtruncate apically. Antennae (Fig. 6E) short, barely extending to the posterior angles of pronotum; scape and pedicel robust, antennomeres III–VII filiform, VIII–X filiform to slightly serrate, XI oval, rounded apically; scape and antennomeres III subequal in length, pedicel shorter than antennomeres III, pedicel and antennomeres IV– XI subequal in length.
Pronotum (Fig. 6F) transverse, distinctly wider posteriorly, 1.4× wider than head, 0.70× longer than wide; surface semilustrous, coarsely and densely punctate, with fine, sparse, decumbent yellowish setae; lateral margins arcuate, widest near midlength, sometimes with few small, weakly developed tubercles; anterior margin nearly straight; posterior margin weakly arcuate; anterior angles obtuse; basal angles obtuse; disc weakly convex, with paired shallow depressions medially, with paired small, deep posterior foveae, foveae connected by shallow groove along posterior margin. Scutellar shield distinctly wider than long, weakly convex, obtuse apically; surface semilustrous, coarsely and densely punctate, with clustered decumbent yellowish setae densely distributed.
Elytra (Figs 3D, 6I) 1.4× wider than pronotum, 2.1× longer than wide, nearly parallel-sided; surface semilustrous, coarsely and densely punctate, with fine decumbent yellowish setae sparsely distributed.
Ventral surface coarsely and densely punctate, punctation on abdomen fine, covered with fine, sparse, decumbent yellowish setae. Abdominal ventrite II (Figs 6K, 7C) with sex patch consisting of long, dense, decumbent yellowish setae. Pygidium broadly rectangular, apical margin weakly and widely emarginate medially, sparsely pubescent. Abdominal sternite VIII subtruncate apically, slightly emarginate medially, sparsely pubescent apically.
Legs slender, relatively short. Claws simple, with basal swelling. Male genitalia with median lobe oriented dorsad the tegmen; abdominal sternite IX forming ring-like sclerite. Tegmen (Fig. 7E) with basale relatively short, stout, deeply concave basally, sides narrowed distally, 1.1× longer than apicale; apicale approximate basally, becoming widely separated apically, acuminate and strongly incurvate distally. Median lobe (Fig. 7E) stout, hastate, divided into broad basal disc and ensiform apex, basal disc and ensiform apex subequal in length; basal disc explanate, produced basolaterally; apex ensiform, tapered apically.
Female (Fig. 3F). Similar to male holotype externally. Ovipositor with sides subparallel, moderately narrowed apically. Paraproct elongate, with length 3.3× coxite, 5.4× longer than wide; proctiger with apex rounded; two distinct ventral and dorsal baculi present. Coxites segmented, sparsely pubescent. Styli short, subcylindrical, inserted subapically. Bursa copulatrix sac-like, distinctly rounded.
Etymology: The specific epithet honours John F. Lawrence, one of the lead editors of the Australian beetles book series, for his invaluable contribution to the development of systematic coleopterology in Australia. His expertise and vast knowledge have greatly improved the state of knowledge of Tenebrionoidea and many other taxa in Australia and around the world.
Distribution: This species occurs widely from southern Queensland to eastern Victoria (Fig. 8).
Remarks: Based on label data, individuals have been collected in light traps with activity during the summer season (November to March).
