[Taxacom] HOLOLECTOTYPE

The term "hololectotype" can indeed be found in Hawksworths glossary
  https://www.gbif-uat.org/document/80577/terms-used-in-bionomenclature-the-naming-of-organisms-and-plant-communities .
Also, "holoparalectotype"!

Speculating about the meaning of an unofficial term allows lots 
of latitude (certainly if one does not know the context), so 
indeed it might be used in contrast to an "isolectotype".

As to entomology, I cannot access the linked texts (behind
a Google Barrier paywall), but although the zoological Code
does know the term "paralectotype", this is defined slightly
differently from the unofficial term in 'botany'. Also, "paratype"
and "syntype" are somewhat different in zoology from 'botany',
making for a different dynamic. So, it is not a certainty that
(this unofficial) usage would be the same under both Codes.

Still, given that the zoological Code does know an official
term "paralectotype" and does not know a term "isolectotype",
and that "isolectotype" is only a recent (2011/12) addition to 
the 'botanical' Code, a relationship between  "hololectotype" 
to "paralectotype" seems more likely than a relationship to
"isolectotype". That is, speaking in general; a glance at the
context may easily tell differently.

The only thing that is clear is that "hololectotype" is a term
best avoided.

  But I am whom I appear to be!   -- and further to what I just wrote, if my suggestion is correct, the author just meant "lectotype". John

  Thinking about the most recent comment on entomological  usage -- not relevant to Lorenzo's query -- I wonder, Paul (the other one), if it is not more likely that "hololectotype" is  being contrasted with "isolectotype" which is an accepted ICN term  John

  Yes, "hololectotype" is meaningless, and a contradiction-in-terms.

  Presumably this stems from the fact that in addition to a holotype
  there can be paratypes.  In informal usage there also exists the
  term "paralectotype", although, despite many attempts to include
  this, it is not part of the Code. This "hololectotype" is, presumably,
  the result of the assumption that since paratypes often accompany
  a holotype, if there are "paralectotypes" (quod non), there must
  also be a "hololectotype".

  Thus, presumably, the intention is to refer to a "lectotype".
