Final answer:
Lorisids are primates in the Lorisidae family, known for their grooming claw, toothcomb, four limbs, external ears, and they typically feed on insects. They are part of the Strepsirrhini suborder and are found in the Old World, with species such as the pygmy slow loris residing in parts of Asia.
Step-by-step explanation:
The characteristics of the family Lorisidae, also known as lorisids, belong to the suborder Strepsirrhini, which includes lemurs and lorises. These primates possess several unique features that separate them from the haplorrhines, or Haplorrhini primates. They have a grooming claw on the second toe and a set of lower jaw incisors tightly packed together, protruding to form a toothcomb. Lorisids are exclusively found in the Old World, which encompasses the continents of Africa, Asia, and Europe.
The pygmy slow loris (Nycticebus pygmaeus), one example of a strepsirrhine primate, can be found in Vietnam, Laos, and a province of China. Lorisids typically have four limbs, external ears, movable eyelids, and a short neck. Although they lack the long tail common to many strepsirrhine species, they have the distinctive grooming claw and toothcomb, and they feed on insects, reflecting their specialization within the diverse array of primates.
