Early Accounts and Description by Experts
The discovery of Megaphobema robustum dates back to the early days of tarantula classification. In 1965, experts initially classified it as a species within the genus Pholcus, but this categorization was later revised. The first recorded sighting of Megaphobema robustum is attributed to Dr. Reginald Pocock, a renowned British arachnologist who described the species in his publication on Brazilian tarantulas.
Dr. Pocock’s initial description highlighted the unique characteristics that set Megaphobema robustum apart from other tarantula species. He noted its distinctive leg span and robust build, which were previously unknown among New World tarantulas. However, it wasn’t until later revisions that the full extent of its differences became clear.
One notable aspect of Dr. Pocock’s description was his observation on the species’ leg hair pattern. He pointed out that Megaphobema robustum has a unique arrangement of hairs on its legs, which are longer than those found in other tarantulas. This characteristic would later become a key identifier for the species.
When examining historical records like Dr. Pocock’s description, it’s essential to consider the limitations and biases of early classification methods. Experts have since refined their understanding of Megaphobema robustum through further research and analysis.
Taxonomic Reevaluation and Current Status
Megaphobema robustum has undergone several changes in its taxonomic classification over the years. Initially described by Pocock in 1914 as a member of the genus Megaphobema, this species was initially considered to be closely related to the Brazilian birdeater tarantula (Lasiodora parahybana). However, further studies and morphological analyses have revealed significant differences between these two species.
In recent years, molecular phylogenetic analysis has provided valuable insights into the evolutionary relationships within the genus Megaphobema. These studies suggest that M. robustum is more closely related to other North American tarantula species than initially thought. As a result, many taxonomists now consider it to be part of the Megaphobema group that includes M. lignariorum and M. robustum.
The current understanding within the scientific community is that M. robustum belongs to the family Theraphosidae, subfamily Theraphosinae. Further research is needed to fully elucidate its taxonomic status and relationships with other species in the genus. Nonetheless, ongoing studies have provided a clearer picture of this fascinating species’ evolutionary history. By continuing to study and analyze the characteristics of M. robustum, we can gain a better understanding of the complex relationships within the tarantula family.

Physical Characteristics and Behavior
Let’s take a closer look at some of the physical characteristics that set Megaphobema robustum apart from other tarantulas, as well as its behavior patterns.
Shell and Pedipalp Description
Megaphobema robustum’s shell is one of its most distinctive features. Measuring between 4 to 5 inches (10-13 cm) in length and weighing up to 15 ounces, it’s a relatively large tarantula species. The carapace, or dorsal surface, has an elongated oval shape with a slightly flattened appearance, while the abdomen is rounded and slightly narrower than the carapace.
The shell’s coloration is primarily grayish-brown, often featuring darker stripes running along its length. In certain light conditions, you might notice a subtle sheen on the shell’s surface due to microscopic hairs. These hairs play a crucial role in the tarantula’s ability to sense its surroundings and regulate humidity levels.
The pedipalps are long, leg-like appendages connected near the mouth, serving multiple purposes such as prey capture and sensory functions. Megaphobema robustum’s pedipalps are relatively short compared to other species but strong enough for manipulating prey. One key difference lies in their modified tips, often featuring a pair of claws or spine-like protrusions that aid in grasping small insects.
When handling these tarantulas, keep in mind that their pedipalps are highly sensitive and should be handled with care. Avoid touching the pedipalp tips, as they can be quite delicate.
Hunting and Defensive Behaviors
Megaphobema robustum, a fascinating and formidable tarantula species. When it comes to hunting and defensive behaviors, this spider has evolved some unique strategies that set it apart from other arachnids.
When hunting for prey, Megaphobema robustum employs a stealthy approach, using its impressive leg span and agile movements to sneak up on unsuspecting insects. Its eight eyes provide exceptional vision, allowing the spider to detect even the slightest movement in its surroundings. But what’s most remarkable about this tarantula is its ability to slow down or speed up its movements depending on the situation – a clever tactic that helps it catch its prey off guard.
In terms of defense, Megaphobema robustum is not afraid to put up quite a fight. It will often vibrate its abdomen and release a foul-smelling liquid from its abdomen to deter predators. If threatened, this tarantula will also rear up on its hind legs, displaying its impressive leg span in an attempt to intimidate potential threats.
It’s worth noting that Megaphobema robustum is generally a solitary creature and only comes into contact with other members of the species during mating season. Despite this, it has developed some remarkable strategies for dealing with predators, making it one of the most fascinating tarantulas in the world.
Life Cycle and Reproduction
Let’s dive into the fascinating world of megaphobema robustum, where we’ll explore its life cycle, from larva to adulthood, and examine how it reproduces. This process is crucial for the species’ survival and success.
Maturity and Molting Stages
Megaphobema robustum, like all tarantulas, undergoes various stages of development from maturity to molting. At maturity, a male Megaphobema robustum can be identified by its smaller body size and distinctive coloration compared to the female. Females, on the other hand, will continue to grow and may live up to 10 years or more in captivity.
As they mature, these tarantulas enter a reproductive phase where males are ready to mate with females. This stage is characterized by the male’s vibrant coloration and robust abdomen, indicating readiness for mating.
Molting, a critical aspect of tarantula development, occurs when Megaphobema robustum outgrows its existing exoskeleton and requires a new one for growth. Before molting, the spider will stop eating and may withdraw into its burrow. Once the new exoskeleton is formed, the tarantula will emerge and continue to grow.
It’s essential to note that Megaphobema robustum requires a proper environment to thrive during these stages. Providing adequate space, temperature control, and humidity levels can significantly impact their molting process and overall well-being.
Reproductive Cycle: Breeding, Egg Sacs, and Hatching
Breeding habits of Megaphobema robustum are not well-documented, but studies suggest that they exhibit a complex reproductive cycle. Female tarantulas typically mate multiple times and store sperm from each mating for later use. After mating, the female will begin to prepare her abdomen by increasing its size and developing an epigyne, where she will store the fertilized eggs.
An egg sac is formed when the female Megaphobema robustum deposits her fertilized eggs into a sac made of silk and tissue. The female then seals the opening with more silk, ensuring that the eggs are protected from external threats. This process can take several weeks to complete, during which time the female will not eat or move.
As the egg sac matures, the female tarantula will eventually deposit it on the burrow floor where the humidity is high. The eggs will then hatch after 2-3 months, depending on environmental conditions such as temperature and humidity. Newborn tarantulas are small and vulnerable to predators.
