Diagnosis. This is the only known member of the genus; therefore, it may be recognized by the characters given in the generic diagnosis above.

Description. Length 1.70–2.10 mm. Color variable, sometimes dorsal surface more or less uniformly reddish-brown, pronotum and head usually darker, elytra near humeri and subapically often diffusely pale reddish-brown ( Fig. 20 ); antennae reddish-brown, club somewhat lighter; ventral surfaces reddish-brown, undersurfaces of head and prothorax often infuscated, legs and abdominal ventrites ( Fig. 94 ) pale. Dorsal setae primarily golden, long, vestiture converging to central point on pronotum, undulating on elytra; tufts of silvery setae present along median line of pronotum posterior of central point, and in paired postscutellar and submedian patches on elytra; elytra with long, sparse, erect setae along sides, with erect setae on disc sparse, arranged in four rows, 2–3× as long as decumbent vestiture. Ventral surfaces with dense, recumbent setae; gula, genae, prosternum and hypomeron medially with coarse, dense punctation; hypomeron sublaterally with wide impunctate strip, with small, dense punctures near lateral edge; prosternal process covered with dense, suberect setae; punctation of metaventrite as dense as that of prosternum, coarser laterally, impunctate in an elongate triangle medially; abdominal ventrites ( Fig. 94 ) with punctures fine, denser than that of metaventrite.

Head with very coarse, dense punctation on frons, especially laterally, punctures separated by less than one puncture diameter, with smooth and shiny interspaces; small area at vertex impunctate. Antennomere 2 subovate, longer than wide, antennomere 3 slightly narrower, longer than 2, antennomere 4 equal in width to 3, shorter than 3 and similar in length to 2; antennomere 11 distinctly longer than 10, shorter than 9 and 10 combined. Pronotal length/ width ratio ~0.82, widest in anterior third, width across posterior angles and across anterior angles approximately equal; lateral edges strongly sinuate, convergent in anterior fourth, anterior angles not at all projecting, posterior angles obtuse, not projecting, posterior margin sinuate, with weak, truncate scutellar lobe; pronotum with broad basal transverse impression, without carinae or paralateral plicae along base; pronotal punctation moderately dense, punctures separated by one puncture diameter or less, with smooth and shiny interspaces, punctures on central part of disc larger, punctures sparser along anterior portion of transverse basal impression. Elytra about 1.45× longer than combined width, about 1.49× wider than pronotum at greatest width, about 2.64× longer than pronotum at greatest length; punctation fine, sparse on disc, separated by about two puncture diameters, denser near basal margin; sutural stria weakly indicated in posterior half of elytron; disc not impressed.Aedeagus ( Fig. 100 ) with tegminal strut weakly present, tegminal arms fused, without a suture; parameres separate and articulated to phallobase, inner surface not concave, length about 2× longer than wide (length taken from the inner bases); apices multisetose, lacking macrosetae; attachment point to phallobase not constricted, interparameral process absent; basipenis 3.5× longer than distipenis, with median carina; distipenis relatively long (about 2× longer than wide), outer rims smooth, lateral lobes not widely separated, symmetrical; internal sac without endophallites.

Etymology. The specific epithet is in honor of the great (magna) Stephanie Bagish, fourth-grade teacher at Crane School (Santa Barbara, California, USA). Stephanie is beloved by all her pupils, especially Ian and Andrew Sheshunoff, devoted visitors of the Santa Barbara Museum of Natural History.

Distribution. Widespread in eastern Australia from at least Mt. Windsor Tableland in northeast Queensland to as far south as Clyde Mountain, New South Wales, Australia.
