{"product_id":"citharognathus-tongmianensis","title":"Citharognathus tongmianensis","description":"\u003cp\u003eCitharognathus tongmianensis is a fossorial (burrowing) tarantula endemic to the subtropical regions of Guangxi, China, and potentially Vietnam, thriving in warm, humid environments that necessitate deep, moist soil substrates for constructing its tubular burrows. Morphologically, the species is defined by its striking sexual dimorphism and unique anatomy; adult females reach a diagonal leg span of approximately 14–15 cm (5.8 inches), featuring a robust body and a distinctive fourth leg pair that is significantly thicker and longer than the first, a trait that earns it the common name \"Stout-Leg.\" \u003c\/p\u003e\n\u003cp\u003eBiologically, Citharognathus tongmianensis is renowned for being only the second known tarantula species to completely lack spermathecae (sperm storage organs) in females, a rare anomaly that challenges standard understanding of mygalomorph reproduction and suggests a unique, yet undocumented, mating strategy.  In captivity, it is regarded as a defensive and fast-moving \"earth tiger\" that prefers to retreat into its burrow rather than stand its ground, requiring careful handling and a terrarium setup that mimics its natural deep-soil habitat with temperatures maintained between 23°C and 28°C. \u003c\/p\u003e","brand":"Fangs Unlimited","offers":[{"title":"3\" unsexed","offer_id":48054392258747,"sku":"FAN-CITHROTONG","price":100.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/fangsunlimited.com\/products\/citharognathus-tongmianensis","provider":"Fangs Unlimited","version":"1.0","type":"link"}
