STEMMOPS OSORNO ( LEVI, 1963) View in CoL , COMB. NOV.

Synonymy:

Anelosimus osorno Levi, 1963: 47 , fig. 58–61, ♂.

Types: Male holotype from Chile, Osorno, Lago Puyehue , 16.ii.1957, L. Peña, in KBIN, examined .

Comments: This small (1.5 mm) species is transferred to Stemmops . It has a distinctly round prosoma ( Levi, 1963: figs 58, 59), characteristic of Stemmops (see Levi, 1964b). It bears a large colulus with a pair of setae, and has a hooded cymbial lock system, a combination unique to some species of Stemmops , and a few spintharines, albeit the latter normally have a small colulus (note that Stemmops groups with spintharines in the study of Arnedo et al., 2004, not with Pholcommatines as in the study of Agnarsson, 2004). It further differs from Anelosimus in having only two promarginal cheliceral teeth, with the outer one larger, by having AME smaller than other eyes, and by having a light central band dorsally on the abdomen. The palpal conformation is unlike that of any Anelosimus ( Levi, 1963: figs 60–61), but resembles Stemmops bicolor , the type of the genus.
