TWO NEW SPECIES OF PAROSPHROMENUS FROM INDONE­SIA DESCRIBED

Octo­ber 28 2021 the arti­cle describ­ing two new species from Indone­sia was pub­lished by our team sci­en­tist and field work man­ager Went­ian Shi, together with his team Shu­jie Guo, Hary­ono Hary­ono, Yijang Hong and Wan­chang Zhang. The arti­cle was pub­lished in the jour­nal Zootaxa and can be found here

Diag­noses of two new species of Parosphromenus (Teleostei: Osphrone­mi­dae) from Bangka Island and Kali­man­tan, Indonesia

Parosphromenus jueli­nae

P. jueli­nae occurs on the island of Bangka, which also is where P. deiss­neri and P. bin­tan occurs, though not in same loca­tions.

Its unpaired fin col­oration is sim­i­lar to that of P. deiss­neri,but it dif­fers from the lat­ter in hav­ing a rounded cau­dal fin with a non-​filamentous branched median ray and a smaller anal fin. Although the new species has the same cau­dal fin struc­ture as P. bin­tan, it can be dis­tin­guished from the lat­ter by its dis­tinct unpaired fin col­oration and the intense red color on the body flanks

This species is restricted to a few adjoin­ing for­est streams and swamps belong­ing to the same river sys­tem in Bangka, which are not con­nected with the habi­tats of P. bin­tan and P deiss­neri. The habi­tats are well–pre­served and rel­a­tively undis­turbed by human activ­i­ties. How­ever, the edge of the dis­tri­b­u­tion area of this species is now under grow­ing pres­sure from agri­cul­tural activ­i­ties. The swamp of the above-​mentioned col­lec­tion loca­tion in 2017 has been drained and con­verted into a paddy field in 2019; thus, likely extir­pat­ing the population.

Parosphromenus kishii

Parosphromenus kishii sp. nov. can be eas­ily dis­tin­guished from all other Parosphromenus by its unique red­dish cau­dal fin with an irreg­u­lar faint turquoise pat­tern and pointed rhom­bic shape.

Parosphromenus kishii sp. nov.is con­fined to a sin­gle river, which now func­tions as a nat­ural irri­ga­tion canal for a large oil-​palm plan­ta­tion. The habi­tat is extremely impacted. Any fur­ther works at the plan­ta­tion may lead to dredg­ing and expan­sion of this river, which may erad­i­cate the only known pop­u­la­tion of this species. Thus, fol­low­ing the IUCN Red List Cat­e­gories and Cri­te­ria (ver. 3.1), we pro­pose that this species be listed as Crit­i­cally Endan­gered B2ab (iii, v), based on its very restricted dis­tri­b­u­tion within a sin­gle river run­ning through an oil-​palm plan­ta­tion (<50 km2) with only a sin­gle known loca­tion and the extremely high like­li­hood of becom­ing extinct due to the poten­tial works of sur­round­ing oil-​palm plan­ta­tions. Imme­di­ate in-​situ or ex-​situ con­ser­va­tion is highly rec­om­mended for this species.

WEL­COME TO THE PAROSPHROMENUS PROJECT

Wel­come!

On these pages you will meet friends of the highly endangered

Licorice Guramies, small labyrinth fishes of the genus Parosphromenus from the peat swamps in South East Asia.

Here you will find all impor­tant infor­ma­tions about these jew­els from the rapidly dis­ap­pear­ing pri­mary forests in Malaysia and Indonesia.

At the same time you will learn all about the Parosphromenus-​Project.

Reg­is­tra­tion — login

9 AUGUST 2022

We have decided to take away the log-​in and reg­is­tra­tion. The only rea­son we had a log in was because it was ness­esary in order to use forum. Theres no hid­den con­tent oth­er­wise on the home­page for ‘reg­is­tered only’.

Since the growth of face­book and face­book­groups, our forum has not been able to stay alive. For this rea­son we decided to turn off the abil­ity to write in forum, and cre­ate new posts. It is still pos­si­ble to search old posts in forum with­out log­gin in.

Species con­ser­va­tion Parosphromenus Quin­decim in the Tier­park Berlina greet­ing from M. Reinecke

Handover from M. Reinecke to animal keeper K. Kappel at Tierpark Berlin.

Hello dear mem­bers of the Parosphromenus project.

The Tier­park Berlin (Markus Klamt) con­tacted me this year about the project, because I offered off­spring of the species Parosphromenus Quin­decim for sale via the Census.

In Novem­ber a meet­ing on site in Berlin has now taken place and I was able to hand over a few pairs to the zoo. I am happy that the Tier­park Berlin wants to con­tinue the con­ser­va­tion of this Parosphromenus species and that we could sup­port them.

I could get an excit­ing look behind the scenes of the zoo dur­ing the han­dover and hope that we can con­tinue the good inten­sive contact.

You can find more infor­ma­tion about Tier­park Berlin here:

Our project:

As I learned from Helene, Rafael, Benni and Went­ian, coop­er­a­tions are very valu­able for the project.

There­fore I would like to encour­age other mem­bers to make their off­spring known for sub­mis­sion in the Cen­sus. The more we are and the more good coop­er­a­tions the project can build up through off­spring, the higher is the chance to get some species in suf­fi­cient numbers.

I wish all par­tic­i­pants and part­ners of the project a good aquar­is­tic start into 2023.
