more "progress" - this time another commonly observed taxon in Hong Kong that has been attributed to the species alikangiae Strand, 1917, until recently in Lyclene and latterly of Miltochrista
There is a recent paper that looks at the alikangiae species group - Volynkin & Černý, 2020 (most of which can be seen on Zenodo - that places this group into a newly described genus: Huangilene. So we now have to refer the Hong Kong taxon to the genus Huangilene. So far, so good. Even I can manage that!
Now is where it pays to be a bit more attentive.
The abstract of Volynkin & Černý, 2020, is as follows (my paragraph formatting to make it easier to follow, with figure numbers from the paper's illustrations (added at the bottom herewith) appended in curly brackets):
Abstract
The new genus Huangilene Volynkin & Černý, gen. n. is erected for the
Miltochrista alikangiae (Strand, 1917) species-group with Lyclene kepica Dubatolov
& Bucsek, 2013 as the type species.
Three new species are described:
H. odontotilepida Volynkin & Černý, sp. n. (Thailand, Cambodia, Laos), {4, 5, 6}
H. kutzscheri Volynkin & Černý, sp. n. (continental China and Taiwan Isl.) {7 to 10} and
H. apoklinousa Volynkin & Černý, sp. n. (Vietnam) {26 to 29}.
Four new combinations are established:
Huangilene kepica (Dubatolov & Bucsek, 2013), comb. n., {1, 2, 3}
H. pseudolutara (N. Singh & Kirti, 2016), comb. n., {11 to 18}
H. alikangiae alikangiae (Strand, 1917), comb. n. {19 to 22}
H. alikangiae intermedia (Marumo, 1923), comb. n. {23 to 25}
The lectotype is designated for Asura obsoleta Form alikangiae Strand, 1917,
the species’ type locality is fixed as “Karapin” (Taiwan, Chiayi County, Chaoliping).
Now then, for Hong Kong these newly defined taxa do not fit with what can be observed with certainty. On geography, One would expect H. kutzscheri to be the species found in Hong Kong, based on the geographic distribution given by Volynkin & Černý, 2020. However, the males of this taxon do not have black abdominal scales on the last few segments. Of the species that do have black scale tufts, pseudolutara occurs too far west, and has an incomplete ring of black scales, leaving only the Vietnamese taxon, apoklinousa with a full set of balck abdominal scales. The problem here is that the gap between the sub-medial fascia and the post-medial fascia is relatively small compared to that observed in Hong Kong material.
How to get round these differences - well for now I am going to suggest the HK taxon is placed only to genus for iNat id purposes, ie. Huangilene. What are the realistic options? Only time will tell - dissection for morphological analysis of the abdominal components and a thorough molecular analysis are needed to resolve the issue. For now, though, I will refer to the HK taxon as Huangilene sp. cf. apoklinousa.
