Many species herewith have been scrutinized by taxonomic experts and will be correct, but this may not be true of all the species described.
IF you do not find a species listed that you know is a species most likely I do not have a photo of it and therefore it is not listed.

 Ring Species: Unusual Demonstrations of Speciation by Darren E. Irwin, Ph.D.   (Site not responding. Last check: )
But determining how speciation occurs in any particular case can be difficult, because we are usually only presented with the outcome of the process (two species) and we often have no record of their common ancestor or the intermediate forms that occurred during speciation.
Ring species, however, show that the ends of a long chain of interbreeding populations can diverge to the point that they do not directly interbreed, even though genes can travel between them through the intermediate populations (in other words, they are connected by 'gene flow').
Ring species might have existed at one time in habitats such as the grasslands of central North America, but those would now be destroyed or severely altered because of the impact of agriculture.

Species: "A grade or rank assigned by systematists to an assemblage of organic forms which they judge to be more closely related by common descent than they are related to forms judged to be outside the species."
With asexual organisms, the method is to compare different strains of a species from every possible point of view and, with the fullest possible array of facts, to arrive at judgements on discontinuities and the probable complexity of their genetic basis.
Species are lineages which occupy an adaptive zone minimally different from that of any other lineage and which evolve separately.

Other species not removed by fire may not be desireable for livestock or wildlife, and need to be controlled by other means (usually herbicides) [33,35].

 Classification of Living Things: Glossary of Terms
the infraclass of therian mammal species in which females produce a placenta to connect the fetus to the uterus.
the infraclass of therian mammal species in which females bear their young in an immature condition (while still in the early fetal stage) and then permit their further infant development in an abdominal pouch covering their mammary glands.
However, we must be cautious in defining species with this criterion because members of very closely related species can sometimes produce offspring together, and a small fraction of those may be fertile to some degree.

 Species, Concepts, Reproductive Isolating Mechanisms, and Geographic Patterns of Variation
This species concept, articulated well by Joel Cracraft (1983, 1987) and Rosen (1978, 1979) views a "species" as the evolutionary unit as identified by evidence for patterns of ancestry and descent.
Species that reproduce by one of these modes are unisexual (all female!) and do not cross breed even with other members of their own species (such as some species of the lizard genus Cnemodophoris in the southwestern United States)!
He states that an evolutionary species is "a single lineage of ancestral-descendant populations which maintains its identity from other such lineages and which has its own evolutionary tendencies and historical fate." This is similar in some ways to the Phylogenetic Species Concept but differs in the way the lineages of related populations are determined.

 Frequently Asked Questions
Having all the species documented [might allow] future generations [to] be able to use the information obtained through the ALL Species effort (e.g., DNA samples, geographic distribution data, ecological association data, etc.) to resurrect entire species, or even entire ecosystems back into existence.
Estimates of undiscovered species on Earth range from 10 million to 100 million and The US National Science Board (1989) predicted that as many as 25% or more of the Earth's species may become extinct by 2014.
For the ALL Species Inventory to succeed, it is clear that these taxonomists will need an army of apprentices, or parataxonomists, to assist them in the initial inventory efforts and sorting of specimens, i.e., all the work preparatory to the expert identification.
