No, the "Newts" are not Chirpers - they are a different "minor race".
They first appear in a "Contact" article in the Journal of the Travellers' Aid Society (GDW's house magazine for Traveller), issue #11 (1982) - Newts
by Loren Wiseman and William Keith.
Here are highlights from their entry in the Traveller-Wiki:
Bawapakerwa-a-a-awapawab: Intelligent minor race native to Marhaban (Empty Quarter 0426).
Known as Bwaps or Wabs (from their name for themselves, Bawapakerwa-a-a-awapawab), they are also known as Newts due to their appearance.
Bwaps average 1.4 meter in height and mass between 30 and 50 kilograms. They are an upright, bipedal, homoeothermic and bisexual, with an internal skeleton and a closed circulatory system.
Appearance: Body markings vary tremendously from clan (“tree”) to clan, each one having a distinctive pattern. The pattern is determined by genetic factors and the color is determined by careful manipulation of the mother’s diet during the formation of the egg. Greens, browns, yellows and blues are most common, usually in patterns of darker colors over a lighter basic color.
Reproduction: Bwaps are oviparous (egg-laying), each female incubating a single, non-amniotic egg in a special pouch on her lower abdomen. After hatching, the young remain in this pouch for several weeks, occasionally coming out to be fed, until they are strong enough to survive outside. The young reach maturity after fourteen years.
Humidity Requirements: Bwaps are uncomfortable in less than 98% humidity, as their skin must be kept moist. With special clothing, they can exist indefinitely in humidity as low as 25%, provided they have adequate water. This normally consists of a loosely fitting kaftan-like garment and a hood covering the head (giving rise to another nickname, “towel-heads”). The cloth of these garments is permeated with a network of fine tubes, through which water flows and keeps the cloth moist. In occupations where they must handle paper or other items which would suffer from moisture, Bwaps wear thin water-proof gloves. In humidity of less than 25%, they must use sealed environment suits. All clothing is colored with a stylized representation of their body, since recognition of body pattern is an important part of their greeting ritual.
Psychology (Cultural Sophontology): From the human point of view, Bwaps are obsessed with minutiae, patterns, and the order of things. Driven by this internal desire to see everything in its proper place, they make excellent bureaucrats, officials, mathematicians, bookkeepers, scientists, and historians.
However, their obsession with ritual and proper conduct can make them difficult to deal with. Those who violate the rituals will be lectured to, at length, on propriety. Dealing with Bwaps takes time, but trying to speed things up only takes more time.
Goals (Motivation): Wapawab ("Tree"): Society is dominated by the Bwap world-view, which holds that each individual has a place in the Wapawab or tree - a view stemming from their habitat, but including phratry, bloodlines, country, and place of duty.
The literal tree is intricately tied into the planetary ecology, providing shelter and oxygen, converting water and minerals into food, etc. The figurative tree is much harder to define, but is roughly equivalent to a clan or tribal group. Both sorts of trees are part of a planet, which is part of a solar system, which is part of a cluster, which is part of a galaxy, which is part of the cosmos.
Everything the Bwaps do reflects this complex, wheels-within-wheels outlook. Each individual takes great pride in being one small, functional and unique cog in a vast, ever-changing universe of interlinked patterns. Their ritual of greeting, for instance, seems like meaningless formality and windy chitchat to non-Bwaps, but communicates: “I am in this place, and doing my part. Where are you and what are you doing?”
Expectations: Criminal behavior is extremely rare, and is considered the worst form of mental disorder among Bwaps, since it disrupts the proper order of things.
Their world-view means that their definition of crime is often at variance with Imperial norms, but, fortunately, most Bwaps courts consider exile to be sufficient punishment, especially in the case of aliens such as humans.
Social Organization: Adventurers: Bwaps encountered away from their homeworlds are often in service to the Imperium or other interstellar entities as merchants and administrators. Such Bwaps serve as ideal Merchant and Professional characters.
Language (Linguistic Sophontology): Very little is known about the Bwap language.
Bwap merchant are known for their facility with the languages of other sophonts. Many Bwap merchants are renowned for their ability to speak a wide variety of languages flawlessly, without accent.
Military & Intelligence (Force Projection): All Bwap worlds maintain a local constabulary and many are garrisoned with Imperial military units.
Martial Tradition: The Bwap need for high humidity make Bwap soldiery less flexible than those of other species although that doesn't stop the martial spirit of many Bwaps.
Many Bwaps serve in the Imperial military, although mostly in support roles rather than as combatants, and even Bwap mercenary units are known. However, as previously mentioned, Bwaps most excel when put in charge of materials or organization; they most excel as administrators, logisticians, quartermasters, and in supply roles.
