Diagnosis. Lasiodora benedeni males and females resemble those of L. parahybana , L. franciscana n. sp., L. klugi (part) and L. sertaneja n. sp. (part) by having spiniform setae only on the upper distal area of the retrolateral maxilla ( Figs 87 ─88). Males can be distinguished from all the above species by the slender apical portion of the embolus ( Figs 76 ─78). Females can be distinguished from those of L. parahybana by having slender stridulatory plumose setae on prolateral coxae (Figs 90─91); from those of L. franciscana n. sp. and L. sertaneja n. sp., they can be distinguished by spermathecae with narrow bulb (Fig. 81). From L. klugi , it differs by the relatively slender and short stridulatory setae spread over the area between the prolateral coxa I sutures (Figs 89─90).

Spermathecae (Fig. 81): Two short spermathecae separated by heavily sclerotized short area, spermathecal stalk slightly narrower than elongated spermathecal bulb.

Color pattern (in alcohol): As in male, except: Legs black with abundant light brown long setae. Abdomen dorsally and ventrally with abundant long light brown setae. Apex of leg segments with whitish rings on apex.

Morphological variation. Lasiodora benedeni males normally have a slender and long bulb embolus with a slender apex ( Figs 76 ─78). Females have slender spermathecae normally closely positioned (Fig. 81). However, some variation was found mainly on the spermathecae, which, sometimes, have their bulbs wider. This normally happens in specimens with very sclerotized spermathecae (pers. obs.) (Fig. 117).

Remarks. The type of L. benedeni Bertkau, 1880 is probably lost, as the majority of the non-European types of Bertkau ( Levi 1991: 203). Fortunately, Bertkau (1880) published an illustration of the spermathecae, something unusual at that time ( Fig. 75 ). He also gave measurements of cephalothorax (20 mm) and abdomen (26 mm) indicating it was a large specimen, and specified the type locality as Chapeu d’Uvas, a small town close to Juiz de Fora, in the state of Minas Gerais, Brazil. With fresh specimens from the region of the type locality and having the information on spermathecae shape and the large size of the type, it is possible to identify the species and to consider it valid. Moreover, it is the only Lasiodora species distributed for a large area around the type locality.

The holotype female of Lasiodora differens Chamberlin, 1917 has a stridulatory apparatus with slender reddish setae on coxae I and II, and spermathecae bulbs are slender (Fig. 99). The type locality is in the distribution of L. benedeni , even though on its western extreme. Thus, I consider L. differens Chamberlin, 1917 a junior synonym of L. benedeni Bertkau, 1880 .

The holotype female of Lasiodora curtior Chamberlin, 1917 has stridulatory apparatus with slender reddish setae on the coxae I and II and spermathecae bulbs are slender ( Fig. 98 ). The type locality in Vassouras, state of Rio de Janeiro, Brazil, is compatible with the distribution of L. benedeni . Therefore, I consider L. curtior Chamberlin, 1917 a junior synonim of L. benedeni Bertkau, 1880 .

The syntypes of L. mariannae are male and female, both from Mariana, state of Minas Gerais, Brazil. The specimens are very fragmented, but the diagnostic structures are preserved. The stridulatory apparatus of the lectotype is formed by a group of slender, reddish setae on coxa I (Figs 102─103) and the spiniform setae on retrolateral maxilla are distributed only on the upper area of the segment (Fig. 104). The male bulb has the apex of bulb slender ( Figs 100 ─101). The paralectotype female has the same structure of stridulatory apparatus ( Figs 106 ─108) and the spermathecae bulbs are slender (Fig. 109). All these characters are compatible with those of L. benedeni , therefore, I consider L. mariannae Mello-Leitão, 1921 a junior synonym of Lasiodora benedeni Bertkau, 1880 .

Mello-Leitão (1921) described male and female of Lasiodora difficilis collected by Cleophas in the state of São Paulo, Brazil. Just two years after, Mello-Leitão (1923) redescribed the species and stated the male is from the state of Ceará and only the female was collected by Cleophas, in the state of São Paulo. Only the female was found at the MZUSP, and, as the male is probably lost, the female MZUSP 139 is herein designated as lectotype. As diagnostic characters, such as the stridulatory apparatus ( Figs 110 ─112) and spermathecae (Fig. 113), are compatible with L. benedeni , I consider Lasiodora difficilis Mello-Leitão, 1921 a junior synonym of Lasiodora benedeni Bertkau, 1880 .

The holotype female of Lasiodora erythrocythara Mello-Leitão, 1921 (MNRJ 50), from state of São Paulo, Brazil, is very fragmented and darkened. However, the stridulatory apparatus ( Figs 114 ─116) and spermathecae (Fig. 117) are preserved and are compatible with those of L. benedeni . Therefore, I consider Lasiodora erythrocythara Mello-Leitão, 1921 a junior synonym of Lasiodora benedeni Bertkau, 1880 .

The holotype female of Acanthoscurria cristata Mello-Leitão, 1923 deposited at MNRJ has the label handwritten by the author, stating “Typo” and “ São Paulo ” instead of Ceará, as in the original description. The specimen has the stridulatory apparatus ( Figs 118 ─119) and spermathecae (Fig. 120) compatible with those of L. benedeni Bertkau, 1880 , species that can be found in the state of São Paulo, but not in the state of Ceará. Thus, I believe a mistake occurred and the real type locality is São Paulo. Due to the agreement in diagnostic characters, I consider Acanthoscurria cristata Mello-Leitão, 1923 a junior synonym of Lasiodora benedeni Bertkau, 1880 .

Distribution. Brazil, southeastern state of Minas Gerais, western state of Rio de Janeiro to eastern state of São Paulo mainly in areas on the Mantiquera mountain range ( Figs 123 ─124). In the state of São Paulo, they are found on the two mountain ranges on the borders of the River Paraiba do Sul valley, the Mantiqueira Range to the west and the Serra do Mar to the east, until close to the Capital of the state, São Paulo. Scattered records for the west and south of the state of São Paulo and Paraná ( Figs 123 ─124) are questionable (see distribution and notes on natural history of Lasiodora above).

Natural history. Lasiodora benedeni is found mainly in areas of Brazilian Atlantic Forest that covers the Mantiquera Mountains Range ( Figs 123 ─124). The area of distribution of this species matches some of the more populated Brazilian municipalities ( Figs 123 ─124), but the species seems to be able to survive in regions with a certain level of anthropization, mainly in rural areas and the borders of large cities, where vegetation still remains. The higher areas of the Mantiquera mountain range and Serra do Mar are of little economic interest and are more conserved, allowing the presence of this species.
