Here is a partially abridged portion of the glossary from the 1985 edition of the International Code of Zoological Nomenclature (ICZN)* which may help in understanding some of the taxonomy terms in dealing with the "type" designations:
type: A term used alone, or forming part of a compound term, to denote a particular kind of specimen or taxon.
type genus: The nominal genus that is the name-bearing type of a nominal family-group taxon.
type horizon: The geological stratum from which the name-bearing type of a nominal species or subspecies was collected.
type host: The host species with which the name-bearing type of a nominal species or subspecies was associated.
type locality: The geographical place of capture or collection of the name-bearing type of a nominal species or subspecies. If the name-bearing type was captured or collected after being transported by boat, vehicle, aircraft, or other human or mechanical means, the type locality is the place from which it, or its wild progenitor, began its unnatural journey.
type series: The series of specimens that either constitutes the name-bearing type (syntypes) of a nominal species or subspecies or from which the name-bearing type has been or may be designated.
type species: The nominal species that is the name-bearing type of a nominal genus or subgenus.
type specimen: A term used in previous editions of the Code for holotype, lectotype, or neotype; also used generally for any specimen of the type series.
*The International Commission on Zoological Nomenclature (ICZN) is the official body responsible for providing and regulating the system for ensuring that every animal has a unique and universally accepted scientific name.
I trust this will be of at least some help in sorting out some the "type" designations used by biologists.
