Boraria profuga comprises two allopatric populations, one in the Ouachita Plateau of Montgomery Co., Arkansas , and the other some 298 km ( 180 mi ) to the southeast in the Gulf Coastal Plain of Ouachita Parish, Louisiana (Fig. 12). As individuals were found exactly four years apart in exactly the same spot, the Louisiana population may be larger and cover a more extensive area. Field work is needed in Ouachita, neighboring parishes, and intervening Arkansas counties, which have received little attention and may or may not harbor the milliped. Published records.

Remarks. Boraria profuga is diagnosed by the variably enlarged, distolateral acropodal shoul- der (Fig. 10-11). According to Causey (1955) , the type series, collected at Mt.

The FSCA also contains specimens collected in 1956 from Montgomery Co. in general. Despite intensive sampling in the Ouachita National Forest in and around Montgomery Co. by Dr. Causey and CTM and associates, B. profuga was not encountered there again, or anywhere in Arkansas , until 2009, a span of 53 years. The lone individual, discovered under a large rock on sandy to sandy loamish soil in an oak/hickory forest, proves that the Ouachita population still exists and should be expected in western Garland Co., only 4.5 km ( 2.8 mi ) to the east. However, B. profuga is difficult to find there and seems legitimately rare; it may warrant formal conservation status, which has never been accorded a diplopod.
