Lasiodora itabunensis : Bonnet 1957: 2356 (unjustified emendation). Diagnosis. Lasiodora klugi male and female resemble those of L. parahybana , L. camurujipe n. sp. , L. benedeni and L. subcanens by the spatulate stridulatory setae on prolateral coxae ( Fig. 13 ), embolus long and slender ( Figs 27 ─29), and spermatheca bulb not enlarged (Fig. 32). They can be distinguished from all the species above by the long stridulatory setae at the confluence of sutures (Figs 35─36). Additionally, the male can be distinguished from those of L. benedeni by the non-slender distal portion of the embolus ( Figs 27 ─29), and females by the non-slender spermatheca bulb (Fig. 32). Male and female of L. klugi can be distinguished from those of. L. subcanens by lacking whitish setae covering carapace, dorsal chelicerae and legs ( Figs 61 ─72); and from L. camurujipe n. sp. by retrolateral distal maxilla covered with short spiniform setae on its median area ( Figs 38 ─39).

Femora, patellae, tibiae and metatarsi of legs and palp with discrete light stripes. Apex of leg segments with whitish rings on apex. Morphological variation. Specimens from the Ilhéus region in southern state of Bahia have the retrolateral maxillae with spiniform setae on its upper, median and lower region, tough the spiniform setae on the median and lower region are smaller and sparse ( Figs 33 ─34, 38─39). Towards the southernmost region of state of Bahia and northern state of Espirito Santo the spiniform setae on the median and lower region of retrolateral palp maxilla are fewer in number, or completely absent ( Figs 43 , 45, 47, 49). Specimens from this region of Bahia and Espirito Santo also have some variation in color pattern. They are brownish and seems to have a small number of long setae on their legs (Figs 66, 71─72), whereas those from Ilheus and neighborhood have normally long yellowish setae over the legs and palps ( Figs 61 ─64, 67─70). Remarks. Schiapelli & Gerschman de Pikelin (1979) examined and illustrated male and female specimens from Cabo and Recife collected by W.A. Forbes, deposited at BMNH (30-125) and cited by Pocock (1901: 544) , considering them as types of L. klugi . Schiapelli & Gerschman de Pikelin (1979) also stated that the Pocock’s (1901) citation of the genus to Cabo and Recife in Argentina was a mistake. Pérez-Miles et al. (1996) considered a male from Iguarassu, Brazil , also deposited at the BMNH and examined by Pocock (1901) , as the type of L. klugi . I examined these specimens at the BMNH and concluded they are not the types of L. klugi . Koch (1841) clearly stated the types are from Bahia in Brazil , whereas the specimens examined by Pocock (1901) , Schiapelli and Gerschman Pikelin (1979) and Pérez-Miles et al. (1996) are from Recife and Cabo (presently Cabo de Santo Agostinho, a town close to Recife, the capital of the state of Pernambuco ) and Iguarassu, all in the state of Pernambuco in Brazil . Most of Koch’s (1841) theraphosid Brazilian types are housed at ZMB and searches on that collection showed the types are deposited there and match the description, two males from Bahia , Brazil under the number ZMB 2039 (Figs 20─26). Those specimens are compatible with the specimens herein examined from the state of Bahia , in its southern portion including the historical city of Ilhéus. The male palp bulb morphology, stridulatory apparatus and general appearance match with specimens of this Brazilian region. Therefore, there is no doubt the real L. klugi types are those deposited at ZMB. The types of L. itabunae are a female and an immature male, both from Itabuna, state of Bahia , Brazil . The specimens have a stridulatory apparatus formed by a few long and slender reddish setae on coxa I ( Figs 57 ─58) and the spiniform setae on retrolateral maxilla are distributed on the upper and median areas of the segment and a few sparse spiniform setae were seen at the lower area (Fig. 59). The spermathecae (Fig. 60) and type locality are also compatible with those of L. klugi . Therefore, I consider L. itabunae Mello-Leitão, 1921 a junior synonym of Lasiodora klugi (C. L. Koch, 1841 ) . Distribution. Brazil , from the “Reconcavo Baiano” region (near the capital Salvador ) in the state of Bahia to northern state of Espirito Santo in the south and east of state of Minas Gerais in the west ( Figs 73 ─74), including the Archipelago of Abrolhos off the coast of the state of Bahia. Rio Doce (Doce river) in northern state of Espirito Santo seems to be a dispersion barrier to the south. Scattered records from the state of São Paulo, Rio de janeiro and southern state of Espirito Santo ( Figs 73 ─74) are questionable (see distribution and notes on natural history of Lasiodora below).

I failed to find morphological differences between the populations from the mainland and the islands. Those from the islands resemble in appearance (Fig. 65) the populations from northern state of Espirito Santo and southernmost portion of state of Bahia (Fig. 66). Natural history. Specimens of Lasiodora klugi are found under fallen trunks, inside burrows, or on the ground, moving on the litter.At night, they are sometimes seen climbing on large trees (pers. obs., Fig. 70). Hollows between the roots of large trees as Ficus spp. seem to be particularly important for the spiders, as they are normally seen using them as retreats (pers. obs.). In the southern state of Bahia , L. klugi can be found in areas having a mixture of Brazilian Atlantic Forest and Cocoa plantation, known locally as “cabruca” that are important to preserve the local biodiversity (Fig. 70). Lasiodora klugi , as other Lasiodora species , are able to survive a certain degree of deforestation being frequently found in forest remnants in urban areas. In the largest island of Abrolhos Archipelago, Santa Barbara, L. klugi is abundant and can feed on lizards ( Tropidurus sp. ) ( Secchin 1991 ). Eickstedt (1971) recorded 3 cases of parasitism by acrocerid flies of the genus Exetasis in L. klugi . Two cases are from the state of Bahia and Colatina, state of Espirito Santo , and are probably of L. klugi . The third case occurred with a spider without locality and cannot be confirmed to this species.
