close to fumipalpis
Comment by geechartier at 30 Jun 2019 07:10:36
@juhakinnunen I agree but am not sure species level ID is possible.
Comment by geechartier at 30 Jun 2019 07:41:56
@juhakinnunen - I find this genus (among many others) confusing. For example, Moths of Borneo suggests that C. bracteolalis is quite different from C. fumipalpis but images on here suggest they are almost indistinguishable. Given the name, fumipalpis, I was hoping for an obvious difference with the labial palps.

@juhakinnunen Sorry, I meant Pyralids of Borneo, not Moths of Borneo. That is the source I looked at. It days C. fumipalpis is similar to others in the fumipalpis group but it suggests that bracteolalis is quite different. Looking at photos here on iNat, I struggled to separate the two species. I do not know which species are in the fumipalpis group.

Close to C. fumipalpis are at least C. bracteolalis and C. kosemponialis (with the Indian C. bifurcalis, of which there was a discussion somewhere here in iNat, with suspicions of it being the same as kosemponialis)...
Comment by juhakinnunen at 30 Jun 2019 12:29:38
Unfortunately there is no original protologue, only the plate, so we do not know why it was originally described with its epithet; fumipalpis refers to "smoky palps". In Pagenstecher's description the palps were missing... Well, after those times experts were having difficulties to say what is what; with the Chinese dissected material at least there is some reassurance that the species in C. kosemponialis-group do exist...

@juhakinnunen Thank you for the paper. It seems to confirm that species level ID is not possible from photographs, given that almost the entire key is based on genitalia.

Comment by hkmoths at 1 Jul 2019 20:03:13
best left at genus rank. the fumipalpis group is not satisfactorily resolved. Globiz Pyraloidea list the three key species as bracteolalis Hampson, 1891 (type loc.: India); kosemponialis Strand, 1919 (TL: Taiwan) and fumipalpis C. Felder, R. Felder & Rogenhofer in C. Felder, R. Felder & Rogenhofer, 1875 (TL: Moluccas) Wang & Speidel (2000: Guide Book to Insects in Taiwan 19) list kosemponialis as a synonym of bracteolalis The 2006 paper by the mainland Chinese reviewing Chinese species in the genus (a shorter link here.... https://www.researchgate.net/publication/241723311) also treated all three taxa as valid. However, as the authors placed the genus in Pyralidae: Schoenobiinae, I'm not sure they can be treated too seriously 🙁 So far as I'm aware, in HK, of this group, we have only fumipalpis
Comment by nagabhushanjyothi at 1 Jul 2019 20:11:03
@hkmoths Sir. Yes I agree with you
Comment by geechartier at 1 Jul 2019 20:18:11
@hkmoths, @nagabhushanjyothi, @juhakinnunen Thank you all.
Comment by geechartier at 1 Jul 2019 20:23:18
The observation is still showing as C. fumipalpis. I tried to edit it but on the edit screen it shows it at genus level.
Comment by hkmoths at 1 Jul 2019 20:54:35
@nagabhushanjyothi - in which case, please update your id suggestion to the genus rank.
Comment by hkmoths at 1 Jul 2019 20:56:56
@juhakinnunen - bifurcalis is given as a jnr syn of kosemponialis on GlobizPyraloidea

Comment by hkmoths at 1 Jul 2019 21:28:08
o.k. looking at the images of Terry Whitaker's Borneo material.... definitely not bracteolalis, which has a brown shaded forewing
Comment by hkmoths at 1 Jul 2019 21:32:53
and looking at the brown fascia on the f/w from the midpoint of the costa that extends to the tornus (=anal angle) - in both fumipalpis and kosemponialis this line has a sharp angle (about 80° in kosemponialis and almost 90° in fumipalpis) where it deviates from the medial fascia towards the tornus. In fumipalpis this line thickens near to tornus. In Gee's Cambodian observation the line to the tornus forms a smooth curve. So not fumipalpis, nor kosemponialis, thus likely an undescribed species in the fumipalpis complex. As you were, gents. Cirrhochrista sp. nr. fumipalpis, pending voucher material being made available for id to species rank
Comment by geechartier at 2 Jul 2019 07:51:32
@hkmoths Thank you. By the way, there are a large number of observations on here of C. bracteolalis that look nothing like its images or textual description in Moths of Borneo.
Comment by hkmoths at 2 Jul 2019 11:16:37
I'm out of time at the moment - must finish the Hong Kong Moth book a.s.a.p. Cirrhochrista on iNat will have to wait... (or others can look now I've given some guidance.....)
Comment by hkmoths at 2 Jul 2019 14:48:54
and having revisited this species for the HK book - looks like the HK "fumipalpis" is the same as the Cambodian one - a smooth arc for the fascia from mid-costa to tornus. e.g. https://www.inaturalist.org/observations/1070001
Comment by geechartier at 2 Jul 2019 17:24:19
@hkmoths Are you now saying this is C. fumipalpis, or still leave at genus level?
Comment by hkmoths at 2 Jul 2019 18:28:30
@geechartier - leave at genus level, please. I have had to edit the entry in the HK moth book (w.i.p.) to read sp. nr. fumipalpis.
Comment by juhakinnunen at 3 Jul 2019 12:34:48
@hkmoths Impressive! Big thanks! (As for C. bifurcalis, there was an Indian observation some two years ago here in iNat, where we had a discussion whether that and kosemponialis are the same, and there the name bifurcalis popped along...)

Comment by geechartier at 9 Mar 2020 18:55:27
@juhakinnunen, thank you. This seems to confirm C. fumipalpis. Even the silver mark on the HW margin is seen in my photo. The only odd thing is that the paper describes the abdomen as brown.
