Name

Typhochlaena seladonia C. L. Koch, 1841 comb. restoredWikispecies linkPensoft Profile

Diagnosis

Males differ from those of other species by the very long male palpal bulb embolus (Figs 1–3). The females differ by the long and slender spermathecae, spiraled distally (Figs 4–5). Additionally, males and females have cephalothorax metallic green and abdomen dorsum black with two series of six spots, the most anterior pair reddish, other yellowish (Fig. 22).

Types

Holotype female of Mygale seladonia C. L. Koch, 1841 [dry, pinned] from Brazil, State of Bahia, Gomez, deposited at Museum für Naturkunde, Berlin (ZMB 2033), not examined, too brittle for mail.

Remarks

Almeida-Silva et al. (2008)[9] redescribed the female of Iridopelma seladonium (C. L. Koch, 1841) after examining photographs of the recently rediscovered holotype of Mygale seladonia C. L. Koch, 1841. They presented photographs of the holotype and an illustration displaying non-spiraled spermathecae from a fresh specimen from state of Bahia, Brazil. A female exuvium examined by myself in this work showed spermathecae with two folds (Fig. 4) and a dissected female showed a single fold spermathecae (Fig. 5). Spermathecae of exuvium could have been modified by the moulting process or by preservation conditions, but the dissected specimen is well preserved. The fold is not easily seen and possibly it was overlooked by Almeida-Silva et al. (2008)[9]. The unavailability of additional specimens prevented me from investigating this question more thoroughly.

Distribution

Brazil, state of Sergipe and northeastern Bahia (Fig. 28).

Natural history

One female was found under loose tree bark in Santa Luzia do Itanhy SE (September 1999). Fig. 23. Two females were found in a similar retreat in nature, in Bahia, and one specimen built a retreat with small pieces of tree bark in captivity (Almeida-Silva et al. 2008[9]).
