Diversibipalium sp., 1 striped

Dongducheon-si, Gyeonggi-do
https://www.inaturalist.org/observations/55258435
"This specimen is close to Diversibipalium multilineatum but lacks the pale zone either side of the dark mid dorsal longitudinal stripe. There are 2-3 other similar species in South Korea that have a black mid dorsal stripe, but they vary in details of the headplate and other morphology."

"An interesting specimen, as there are at least two-three single-striped species in Korea. This specimen differs from Biaplium monolineatum because of its length, that the dark mid-dorsal stripe passes onto the headplate, and that there is not a pale zone either side of the mid dark stripe. The other two species are much smaller, with a light yellow ground colour and median stripe passing onto the headplate."

geoplanid subfamilies & tribes

1) Bipaliinae
Hammerhead flatworms.

Bipalium
Bipalium monolineatum (Type loc: Chionin and Mt Hiei, Kyoto, Japan)
Diversibipalium - pending species collection

2) Geoplaninae
chiefly accommodates South American genera that have multiple eyes (leigh_winsor, 22 Apr 2020, https://www.inaturalist.org/observations/42584951).

3) Microplaninae
Two-eyed flatworms.

Generally short, plump cylindrical form, anterior end often blunt, eyes small. Weak body musculature; male copulatory organ often complex generally well developed penis papilla, female organs simple or complex (leigh_winsor, 17 Apr 2020, https://www.inaturalist.org/observations/41590117).

Microplana ruteocephala (Type loc: Nikko, Japan)

4) Rhynchodeminae
comprising six Tribes, largely accommodates Australian, New Zealand and some Asian genera. Within the Rhynchodeminae there is the Tribe Rhynchodemini that contains the two eyed forms, the Caenoplanini with multiple eyes that includes Australopacifica as per the GBIF, and also the Tribe Pelmatoplanini that contains taxa with multiple eyes that are restricted in their distribution along the body - they are generally confined to the head region (leigh_winsor, 22 Apr 2020, https://www.inaturalist.org/observations/42584951).

body elongate with tapered ends, with subterminal eyes, with strong cortical musculature especially longitudinal muscle that are grouped into bundles, penis papilla absent or reduced, female organs simple (leigh_winsor, 17 Apr 2020, https://www.inaturalist.org/observations/41590117).

Artioposthia japonica
Australopacifica
Australopacifica lapidicola (Type loc: Okinawa Isl, Japan)
Australopacifica bimaculata (Type loc: Nikko, Japan)
Rhynchodemus
Rhynchodemus ijimai (Type loc: Nikko, Japan)

Of course, the eyes are only one morphological character in the current classification of land planarians that is based upon DNA evidence combined with morphological evidence - body musculature, width of the creeping sole, and the anatomy of the reproductive organs including the gonads play a large part in the classification (leigh_winsor, 22 Apr 2020, https://www.inaturalist.org/observations/42584951).

It would be helpful to obtain material fixed to preserve the DNA, but this requires preservation in pure 95-98% ethanol (analytical reagent grade) - the presence of denaturants and other contaminants in the ethanol make it impossible to extract useful DNA (leigh_winsor, 22 Apr 2020, https://www.inaturalist.org/observations/42584951).
