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.

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.

Parosphromenus spe­cial behav­iour. 1

Do all parosphromenus species stand on their head when flash­ing ? – some­one asked me the other day at a presentation.
No – they don’t.
It’s a pecu­liar thing, that most of the paro-​species we know do stand head down when flash­ing, yet we know of 3 species that do the oppo­site. When the males do their lit­tle dance in front of the female they stand head up.
These 3 species are ornat­i­cauda, parvu­lus from Bor­neo and suma­tranus from Sumatra.
Ornat­i­cauda and parvu­lus are nor­mally thought of as paro-​species that dif­fer from the oth­ers paro-​species, in not only this way, — but also in bodyshape, size and gen­eral demands.
