03AE4355FFE3FFECFF28FC4CFDA9FCFC.taxon	etymology	Etymology. The species epithet “ tequesta ” is treated as a noun in apposition and is in honor of the Tequesta indigenous people who once lived in southeastern Florida and the Keys, and are now apparently extinct. Notes. Dipropus tequesta is apparently endemic to southern-most Florida, and is morphologically similar to certain undescribed Dipropus species from Cuba. It differs from other described species of Dipropus in the eastern United States by the characters used in the key below, in addition to the combination of the antennal length, antennomere length ratio, pronotal punctation, and aedeagal (Fig. 2) characters as described and illustrated.	en	Mathison, Blaine A., Johnson, Paul J.

03AE4355FFE5FFEDFF28FF4FFC84FCBC.taxon	materials_examined	This species was originally described from Indiana and is currently known from throughout much of the eastern United States. There are no type specimens for this species in the MCZ where the remaining Say types were deposited (Johnson 2016) and the type is believed to have been destroyed. Johnson (2017) examined the type of Ischiodontus oblitus housed in the BMNH, which had been labeled as I. soleatus by Becker in 1975, and designated it as the lectotype of I. soleatus (for a complete history of this specimen, see Johnson 2016). Clark (1963) previously considered I. oblitus a synonym of D. simplex (LeConte, 1853). The aedeagus of Johnson’s lectotype is not consistent with the written description of the D. soleatus genitalia as described by Clark (1963). It appears that Clark based his descriptions on previously identified material and was possibly examining a specimen of D. simplex when he described the aedeagus of D. soleatus. Clark also used the texture of the elytra to separate D. fuscus and D. soleatus, but these characters are highly variable and unreliable to diagnose species of Dipropus. The aedeagus of the I. oblitus type is identical to that of LeConte’s type of A. fuscus and we hereby propose A. fuscus as a new synonym of D. soleatus. Examination and dissection of many specimens throughout the study region show a strong correlation between the I. oblitus-D. fuscus aedeagus type and the shape of the pronotum. Other characters, such as body size and size of membranous tarsal pads, appear variable with no apparent correlation with one or the other.	en	Mathison, Blaine A., Johnson, Paul J.

03AE4355FFE5FFEFFF28FC4FFB85FE7C.taxon	description	Description of female of D. asper (Fig. 3). Body length 5.8 – 5.9 mm, width 1.9 mm wide; robust, convex, laterally subparallel; integument red-brown, pronotum slightly lighter than elytra; appendages concolorous with body; vestiture long, dense, yellow-gray in color. Head with frons densely punctate, punctures shallow, umbilicate, separated by a distance less than their diameter; frontal margin formed by supra-antennal carinae complete, broadly rounded in dorsal view; eyes present but smaller than in male, partially concealed by both the frontal area of the head and the anterior margin of the pronotum; antennae very short, not reaching mid-length of pronotum, antennomere 1 long, antennomeres 2 – 11 short, rounded, moniliform. Pronotum subquadrate, slightly wider than long, 1.5 mm long by 1.7 mm wide, slightly shiny, densely punctate, punctures shallow, umbilicate, separated by a distance less than their own diameters; hind angles very slightly divergent, unicarinate, carina short, not reaching base of hind angle and gently curving along lateral margin; hypomeron and prosternum sparsely punctate, punctures very shallow, umbilicate; prosternal sutures closed; prosternal process sharply reflexed upwards. Elytra with strial punctures large, narrowly separated; intervals distinctly punctured, granulose; conjointly rounded at apex. Metathoracic wings present, not folded, just reaching the last abdominal tergite. Legs shorter than in male; row of stout spines on tibia and tarsomeres 1 – 3; tarsomeres shorter than in male, tarsomeres 2 – 3 lacking membranous lobes; claws simple.	en	Mathison, Blaine A., Johnson, Paul J.

03AE4355FFE5FFEFFF28FC4FFB85FE7C.taxon	discussion	Discussion. Both specimens were found associated with males, with the Highlands County specimen found in copula. The female possesses brachypterous metathoracic wings, not longer than the elytra. Other distinctive features of the females such as the shorter legs and tarsi and reduced eyes and antennae are seen in the females of other psammophilous elaterids from the southeastern and southern Coastal Plains (e. g. Floridelater americanus (Horn) and Selonodon spp.). The lack of membranous lobes the tarsomeres and the proportionately large tibial spines, brachypterous metathorax, and the stout body form, and the collecting situations suggest that the females of D. asper are most-likely generally flightless and are adapted to subterranean activity in sandy substrates.	en	Mathison, Blaine A., Johnson, Paul J.
