description
Saether (1977) stated in his key that the superior volsella of C. emorsus was “ without microtrichia ”; Yan et al. (2005) made a similar statement in their key. However, examination of numerous specimens, including the holotype’s hypopygium, indicates that the appendage does bear microtrichia near the base (Figs. 5, 6, 7). This condition was also noted in Zorina’s (2006) key to Far Eastern Russian Cryptotendipes species. Most pupae bear a row, interrupted medially, of clear, thin spines anteriorly on S I and II; Saether (2010) noted them only on S I. Saether (2010: 9) gave postmentum lengths of 120 – 130, mean 125 µm for C. emorsus larvae. In a sample of ten larvae from Florida, postmentum lengths ran from 118 – 143, mean 127 µm. This is the most common species of Cryptotendipes in Florida.
