In case you don't know, there is no such family as Hyloblatidae. There is a family Hylobatidae which is divided into four genera. Those four genera are divided into species. All organisms can produce normal, fertile offspring or they would immediately go extinct. "Kinds" is not a scientific term, so I don't know what you're asking.

Hylobatids (Hylobatidae) and great apes (Hominidae) are two families from the superfamily Hominoidea. There are many differences between these two families, some of them being:Hylobatids are significantly smaller in size than great apes.Hylobatids are exclusively arboreal animals (they spend all their lives on trees), while great apes are mostly, but not exclusively arboreal.Hominidae are exclusively omnivores, Hylobatidae are mostly omnivores.

For those of you who don't know, Hyloblatidae is Latin for 'forest walker apperance, and its common name is 'gibbon'. I don't genera, species, or subspecies; I mean kinds. Like in, can produce normal, fertile offspring.
