03DCFC71FF9DFFB6FC55FD58FE9BFE26.taxon	diagnosis	Diagnosis: The females are easily distinguished from other species of the genus as the tergite 6 pincers structures lack any denticules or strong setae on their inner margin. The males have some silver pruinosity on the abdomen, usually anteriorly on the last segments, as well as in the head.

03DCFC71FF99FFB9FF69FE1CFD72FB63.taxon	diagnosis	Diagnosis: Females are easily distinguished from other Leucostoma by their long and slender abdomen, tapering distally (Fig. 6). All abdominal segments are similar in length / width ratio, however, the fourth tergite is telescopically retracted and seems wider (the retracted anterior portion lacks strong setulae). The males resemble L. simplex, according to Reinhard (1956), but the abdomen has pruinosities on the last two segments and is narrowed distally, not as much in females. Other characteristics are used in Reinhard’s identification key. The male terminalia (Fig. 4) likely has some features that will distinguish them from other Leucostoma species, but we lack material and illustrations to compare. Redescription: Male (Fig. 6 A – B).
