The external features of L. uhleri closely resemble those of L. kryptus, with both species sharing a broadly overlapping geographic distribution. However, females of uhleri have a more angulate head and are a little larger than kryptus females. (McKamey 2001) Additionally, the pregenital sternites of the two species are different per Beirne (1956). In kryptus, the sternite is distinctly trilobed with a sinusoidal posterior margin; there also appear to be two pale spots on the anterior margin, with the rest of the sternite dark. In uhleri, the sternite is wider [than in kryptus] and largely blackish, and is more bilobed than trilobed with a gradual median projection that doesn't quite extend out as far as the pointed lateral margins of the sternite.
