955A8790397D7630FF1D9600F871FE0A.taxon	diagnosis	Diagnosis. Species of the pubescens group share some characters that distinguish them from all other Polyphylla. The most notable characters are the vestiture of setae (not scales), pronounced sexual dimorphism (Fig. 22 - 29), and male genitalic form. Male. Length 15.3 - 25.0 mm, width 6.9 - 12.0 mm. As with all Polyphylla, males have seven lamellate antennomeres in the club (Fig. 6, 8). Males of the pubescens species group are unique in Polyphylla by having dense, short dorsal pubescence made of setae (devoid of scales), relatively narrowed protibiae with 2 lateral teeth (rarely a weak basal tooth is visible), and genitalia with apex laterally flattened and semicircular in lateral view. Female. Length 15.0 - 25.0 mm, width 6.9 - 14.0. In addition to being distinctly more robust overall, females of the pubescens species group differ from males in having the apical clypeal ridge reduced, five weakly lamellate antennomeres in the club (Fig. 7, 9), greatly reduced dorsal pubescence, protibiae with two lateral teeth much more pronounced, metafemora much more robust, metatibiae greatly dilated at apex (Fig. 14 - 21), and more spatulate meso- and metatibial spurs. Although flight wings are present, female body and appendage morphologies indicate they do not fly, which is corroborated by all behavioral observations.	en	Skelley, Paul E.

955A8790397C7634FF1D970EFA16FBEA.taxon	diagnosis	Diagnosis. Polyphylla starkae is a member of the pubescens species group and unique with males having elytral setae clustered into groups, some in vague stripes (Fig. 2, 4, 22). This species is the largest member of the pubescens group and is strongly sexually dimorphic. Females are more robust than the males (Fig. 3, 5, 23) with legs modified for burrowing (compare Fig. 10, 14) and elytral setae nearly absent. Although flight wings appear fully developed, female elytra are tightly connected at the base along the suture, suggesting females are flightless.	en	Skelley, Paul E.

Elytral length 3.3 x length of pronotum; lateral margin weakly reflexed, sharp lateral edge reaching middle of humerus, not attaining base; surface glossy and mostly glabrous with widely scattered punctures bearing fine setae; setal covering visible along the sutural, apical and lateral margins complete although variable in width; elytra were tightly connected at basal quarter along suture and they were separated with some difficulty. Flight wings present. Venter with metathorax and abdomen similar to male holotype. All femora with surface somewhat convex. Pro- and mesofemora weakly arcuate most of length. Metafemora distinctly dilated, 1.5 x wider than mesofemora, margins strongly arcuate, length 2.1 x maximal width.

Metatibia parallel-sided along middle half of length; tooth at middle of outer edge weak; abruptly widened near apex; apical spurs curve downward on lower edge; lower spur flattened, gradually narrowing to acute apex, upper spur somewhat spatulate, widest at middle; portion of apical tibial plate below tarsal junction same size as upper part. All tarsi with teeth equal in size. Variation. Male. Length 21 - 25 mm; width 10 - 12 mm. Anterior clypeal margin on most is weakly sinuate in anterior view, is somewhat raised in the middle on a few. Lateral pronotal margin, evenly arcuate on most, is slightly angulate on a few. Patches of elytral setae vary in size in the specimens available. On some, their somewhat linear arrangement is clearer, but never prominent, on others it is imperceptible. The elytral pattern of radiating lines in reflected light is not visible in most specimens. Two specimens studied had patterning identical to the other members of this group. Body color also varied from light brown to dark brown, almost black. Female. Length 23 - 25 mm; width 13 - 14 mm. Body color in life varied from the reddish-brown (Fig. 3, 5) to a chocolate brown, similar to the pinned specimen in Figure 23. All specimens darkened when preserved.	en	Skelley, Paul E.

955A8790397C7634FF1D970EFA16FBEA.taxon	etymology	Etymology. Named for Donna Stark, who first collected this beetle, attempted to identify it, and brought it to our attention (see Palmer 2009). Survey efforts such as hers are greatly needed to discover and document our indigenous invertebrate fauna. Common Names. Woodruff and Deyrup (1994) called “ P. pubescens ” the “ panhandle beach scarab. ” Unfortunately, this name refers to the species later recognized and named P. woodruffi Skelley (2004). True P. pubescens is not known to occur on beaches and is here named the “ Eglin uplands scarab ”. Given the immediate interest P. starkae has raised among naturalists, conservation groups and other political entities in Florida, it is fitting to propose a common name for this new species. Thus, I am proposing P. starkae be known as the “ Auburndale scrub scarab. ”	en	Skelley, Paul E.
