Tliltocatl kahlenbergi (ex. Brachypelma) • 1/2″


Tliltocatl kahlenbergi (new Mexican red rump), captive bred, a medium-size fossorial from moist subtropical forests in Veracruz, Mexico. Recommended for all levels (limit 5/customer).

Tliltocatl kahlenbergi was described in only 2008 [1]. Recent discovery is interesting given it comes from Veracruz, the third most populous state in Mexico, and given widespread distribution within Veracruz [2].

T. kahlenbergi is distributed in subtropical, moist-forest lowlands, east of the Sierra Madre Oriental [2][3]. Appearance is similar to that of Tliltocatl epicureanum and Tliltocatl vagans. The resemblance is most evident in dark-carapace morphs [3]. A lightly masked, bronze-carapace morph is not uncommon, and a pale-carapace morph may exist.

Like its Tliltocatl and Brachypelma cousins, T. kahlenbergi is fossorial, living in constructed or modified burrows. Captive, mature specimens will take advantage of a hide, rarely excavating their own shelter.

Fukashima et al report August-January as mating season, when rainy season changes to dry. Sacs appear in winter and young emerge “about two months later, with most young dispersing in the late spring or early summer, just before the onset of the early summer rains” [2].

Eddy Hijmensen (2011) reports the Tungara frog, Engystomops pustulosus (Cope), living in the same burrow as Tliltocatl kahlenbergi.

Spiderlings here are eating 1/8-1/4″ crickets.

The photo above shows a bronze-carapace female, of the same lineage as the spiderlings offered. As with most New World tarantulas, colors change during the molt cycle (recent molt). Carapace shade is lighter in immature specimens. The genetic versus environmental determinants of adult carapace color are not yet known.
