Erect setae on the pronotum are abundant. A tarantula perceives its surroundings primarily via sensory organs called setae (bristles or spines). The pronotum is evenly curved with at least 12 or more pronotal setae present. The telson is pointed and is usually armed with four pairs of setae or spines. The larvae are elongated and densely covered in large setae (hairs). These setae are mostly short and bristly. Brown pereiopods and pleopods are present with fringing setae in red. Certain species have distinctive tufts of setae extending from their posterior end. The sporophyte produces spore capsules (sporangia), which are connected by stalks (setae) to the archegonia. They are carrot shaped and heavily covered with setae, especially on their posterior end. Filtering appendages generate water currents that bring food items into reach for collection by setae. The latter species shares the hooked hymenial setae and ellipsoidal to broadly ellipsoidal spores. These larva are distinctive due to a swollen thoracic region and multiple golden setae. Larvae are yellow-white but the head and body setae are brown. Newly hatched larvae are black with long, hair-like setae.
