Remarks. This species is very similar to Cr. muellerianae but can be readily distinguished by lacking setae tc'' on tarsi I–IV (present in Cr. muellerianae ), the stouter palpal segments (finer in Cr. muellerianae ), lanceolate setae h1 (more palmate in Cr. muellerianae ), and irregular dorsal reticulation (linear in Cr. muellerianae ).
