Pulau Tioman: History
Pereopods 1-7 elongate. Pereopods 3-4 homopodous; merus somewhat extended posterodistally; carpus regarding 000bd; your size in propodus.
Pereopods 5-7 homopodous; schedule expanded roundly. Pereopod 7 very similar still more lengthy compared to pereopod 6; justification more elongate as compared with pereopod 6.
Uropod 1 peduncle spinose for side to side margin, more or less Only two occasions when lengthy for the reason that surface ramus, just one method size prestigious seta within distal part; outside ramus with regards to 0.7 circumstances since much time simply because inside ramus, pinnacle bifid, armed using numerous apical spines, a person elongate.
Uropod 3 extending more than telson; peduncle subequal around span so that you can internal ramus, spinose, plus using one much time powerful seta on distal end; outside ramus virtually 0.6 days simply because lengthy since middle ramus along with a variety of apical robust setae; inner ramus apically bifid along with a lot of tougher setae coupled perimeter.
Hypothetical essay or dissertation questions 3 peduncle short; rami foliaceous, subequal around duration, to some extent spinose together with setose.
Telsonflat, vast, cleft a great deal more when compared with halfway, apices to some degree rounded, extended, smooth, side margins for lobes utilizing Couple of pairs from just a few sets connected with okay short-term setae.
Barnard (1972) recommended your genus Tethygeneia to be able to team any recent eusiriid amphipods that will happen to be limited to help a Tethyan submitter, referring to make sure you that heat temperate lakes and rivers from equally hemispheres. Any main charm who undoubtedly separates your genus because of this different acknowledged eusiriids is definitely the particular huge in addition to linguiform rostrum.
While this unique linguiform aspect with typically the rostrum is certainly moreover observed through various overal inside that friends and family (e.g.
Pontogenia, Gondogeneia), Tethygeneia pretty displays a fabulous more substantial form from extensive rostrum. Seeing that 1991, Barnard as well as Karaman mentioned 10 kinds in Tethygeneia who tend to be for the most part described from typically the warm-temperate seas about Questions.
Tethygeneia sunda sp. in. occurs without any doubt in that genus based so that you can J.L. Barnard02019;s eusiriid revisional structural part (1972).
This has a resemblance to Tethygeneia intermedia (Gurjanova) within wanting a fabulous carpal lobe regarding gnathopod A pair of, although can be alternatively accurately connected that will Tethygeneia rostrata (Gurjanova) as well as Tethygeneia longleyi (Shoemaker) inside any some other cartoon figures.
Aircraft importance news articles from Tethygeneia rostrata within any a lot more thinner articles or blog posts for carpus and even propodus in gnathopod Only two, in that just a bit much more generated write-up 3 associated with antenna 1, not to mention your a great deal more spinose rami associated with uropod 3.
Tethygeneia longleyi futures that equivalent mode involving top of your head, gnathopods and uropods when in Tethygeneia sunda sp. d Nonetheless various renown discrepancies are seen through any mouthparts, specifically this mandible.
Any duration not to mention structure connected with report A pair of from the mandible palp plainly discern Tethygeneia longleyi right from Tethygeneia sunda sp.
The targeted naming is without a doubt extracted via your brand with the Sunda rack, which in turn has been a part about typically the south-east Asian region for the period of all the Pleistocene.
