Dr Bonaldo was inspired to name the spider after Sir Peter after spending time on the Seamaster when it returned to the Amazon to make a BBC documentary about Sir Peter's life.
The spider was found at a scientific station in the state of Para, the site of a large-scale biosphere experiment trying to find answers to issues such as preventing global warming.
"This is why I choose this particular spider to honour Sir Peter. I believe he could be happy seeing his name associated, even indirectly, to such an effort.
"To me, to name a spider after Sir Peter is an opportunity to make his message more known among Brazilians."
The Blakexpeditions website says it is hard to know which honour Sir Peter would have been most proud of - his knighthood or the spider.
No decision has yet been reached on the fate of Sir Peter's killer, Ricardo Colares Tavares, and his gang of robbers who boarded the Seamaster in the dead of night.
The judge has agreed Colares Tavares, who shot Sir Peter twice in the back, be allowed to undergo psychiatric tests but New Zealand's ambassador in Brazil, Denise Almao, said there was no timetable as to when they would be completed.
Although Colares Tavares has already admitted his guilt, a finding that he is psychiatrically disturbed could reduce his sentence.
The Herald's interpreter in Macapa, Brazil, Francisco Franca, says documentation of Colares Tavares' previous record shows that in 1999 he was jailed for five years in the state of Minas Gerais for robbery but was released for good behaviour in April last year.
He came to Macapa, a town at the mouth of the Amazon River near where Sir Peter was killed, apparently because under the Brazilian justice system he was allowed to undergo his punishment near where his parents lived.
