Info?

I tried to compare this with the illustrations of similiella in Bottimer (1926) and rudbeckiella, erroneously named similiella, in Heinrich, (1921). Bottimer says "Both species have the harpe of the male genitalia divided, but in the new species it is nearly twice as long as in similiella." I don't know enough about genitalia to tell what this. I added the references to both species pages. Could you please reconfirm the ID for MPG?

I can't interpret Fig. 2 E (similiella male genit) in Bottimer (1926).
When one has only 1 image a term such as "twice as long" is meaningless.
However, the harpe in my image, which I believe is the thin pointed rod on the lower curve of the left valve, seems short - suggests similiella.
Those pale circular structures could be the harpes, if so, don't know if they are short or long!

Isophrictis rudbeckiella

I see now that Bottimer (1926), p. 807, fig. 2 E, illustrates true similiella genitalia and that, per Bottimer (1926), p. 808, the illustration of similiella in Heinrich (1921), pl. 95, fig. A, is actually that of rudbeckiella. The harpe would appear to refer to the valva. Yours are twice the length of those for similiella. Please take a look and let me know what you think.

Hasbrouck (1964), p. 683, fig. shows the harpe.

Links broken

Steve, the link to the 1926 Bottimer paper in J. Agr. Res. is obsolete. Unfortunately, BHL doesn't currently have a digitized version of that volume (that I can find). Know of an alternate online source?

Link Replaced

I think you now need an account to see it, so I replaced with a URL I found to an archived copy using the Wayback Machine at Internet Archive.
