Pamphobeteus sp. machala

Pamphobeteus sp. machala

Pamphobeteus sp. machala, also known as “Purple bloom”, is a very remarkable bird spider due to its size and coloration from South-Ecuador. However the females lose their bright colors reaching adultery, the males are shining bright with their beautiful purple palet. Until now the bird spider hasn’t been officially published yet. Machala is referring to her native habitat in Ecuador.


I. SPECIFIC INFORMATION

Scientific name: Pamphobeteus sp. machala.

Subfamily: Theraphosinae.

Also known as: Purple bloom tarantula.

Previous names: The spider hasn’t been officially published yet.

Type: Terrestrial bird spider.

Category: New world tarantula.

Urticating setae: Yes, type I/III (abdomen).

Venom: Probably mild. No valuable scientific research has been done yet.

OriginEcuador (Machala).

Body length: ≤ 8-9cm.

Span width: ≤ 18-22cm.

Behavior: In general, Pamphobeteus sp. machala is a docile species. Nevertheless the exception makes the rule. Some spiders will not hesitate to shed its urticating setae, but a threat pose is rare. As the spider gets older, she’ll become calmer. During the day they’ll stay in their burrow, coming out at night.

Growth rate: Fast.

Life expectancy: Females can become up to 20 years old. Males are given a shorter lifetime from 3/4 years.

Accessibility (1/beginner, 10/expert): 4.


II. INFORMATION FOR KEEPERS

>>> First aid

Pamphobeteus sp. machala lives in tropical warm and humid area, in tropical rainforests of South-America. Temperatures may vary, reaching 30°C during summer and cooling down significantly down 20°C during winter. Please be informed of the fact the spider will protect itself against the weather underneath tree trunks, branches, leaves and abandoned burrows. Do not overheat the terrarium.

Environmental conditions

Temperature: Summer: 24-28°C (day), 20-24°C (night). Winter: 18-21°C (day), 16-18°C (night).

Humidity: 65-75% (summer), 80-90% (winter, 4 months).

Terrarium

Adult: LxWxH: 40x40x30. Min. 3x span width in surface.

Smaller than adult: Min. 3x span width in surface.

Substrate

Adult: 1-1,5x body length. Breeding min. 1x span width.

Smaller than adult: Min. 1x span width.

* The spider lives in tropical forests. Provide many branches and leaves. She’ll use it to create her burrow.

* The spider is an opportunistic burrower. Do not deprive her this opportunity in your terrarium.

* The spider lives in wet area. Note that cages with high humidity levels are very sensitive for mites and other parasites. Please take your precautions.

Climate

Wet season: October, November, December, January, February, March, April.

Dry season: None.

Warmest month: April.

Coldest months: August, September.

* You might like to consider an adjustment of these data with your local climate. Do not exceed minima or maxima and, if necessary, organize the year making your bird spider experience different seasons. This is very important form the moment you’d like to start breeding.


III. INFORMATION FOR BREEDERS

Pairing a Pamphobeteus sp. machala does not always run smoothly. Cannibalism may occur before or after copulation. Remarkably the spider is being triggered to make the cocoon from the moment humidity drops and temperature rises. If you’re not paying attention to this rule, breeding results will probably turn out negative.

• Only start breeding 4-6 weeks (or later) after the spider molted. If the female molts between pairing and cocoon, the eggs will remain unfertilized.

• Make sure the female is well-fed (not obese) before you introduce the male.

• Plan mating in autumn, followed by a wet (80-90%) and cold (18-21°C) winter. Systematically raise up temperatures (26-29°C) while dropping humidity (60%) after 3/4 months. This will trigger the female to start making her cocoon.

• 4-6 months (sometimes even 8-9 months) after mating she will start making the cocoon. Deprive the cocoon, when desired, 5 weeks later. Store the eggs (150) at a humidity of 60% and a temperature of 26-29°C. Make sure no moldproblems occur.


IV. DID YOU KNOW… 

• Breeding is more successful when given a rather dry (60%) period after a cold (18-21°C) and wet (80-90%) winter?

• Bird spiders from the Pamphobeteus-, Xenesthis– and Vitalius-genus are very hard to distinguish by the unexperienced eye?

Pamphobeteus-spiderlings have a beautiful pattern on their abdomen?

• All species with “sp. location” are not yet being published officialy?

  1. “Terrarium
    Adult: LxWxH: 30x40x25. Min. 3x span width in surface.” Are these measures in inches?
    If span is 25/26cm then 30 x40cm is a lot less than 3 x span… but why change units half way through the article without explaination? Or is this a typo?

    1. Hey Gwen,

      Thank you for your reply. All measurements are in centimeters. I’ve changed a little, as experience confirms even span width is different. Please rely on your common sense, as you did, when you read small errors like this. I don’t make these doubtful statements on purpose. Investigation methods changed throughout the years as well, for which reason especially the first pages written on this website contain quite a few small errors. You’re always welcome to bring them up 🙂 Kind regards.
