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.

Parosphromenus bin­tan ’Bintan’.

For the new con­ser­va­tion project of Parosphromenus Project, we imported some Parosphromenus sam­ple from Bin­tan Island. Col­lected by a local friend, who lives in Bin­tan Island​.In a post from Feb­ru­ary Went­ian Shi wrote in Jour­ney to the water that some inter­est­ing obser­va­tions of this imported fish, raised the ques­tion – or ques­tions : Either the orig­i­nal P. bin­tan was not entirely blue, as described, but has a small inte­rior band of orange red, — or there may be a sec­ond species/​type on the Bin­tan Island.
