(A. Chagas Jr., B. Segal, E.G. Vasconcelos) (MNRJ-11343). One
paratype
deposited in the Muséum national d’Histoire naturelle, Paris.
Diagnosis
. Species of small to moderate size when compared with the average size of the other species of the genus (
19.9 mm
in total length; see
Table I
). General coloration yellowish with variegated dark pigmentation. Pedipalps very slender; fingers with 6 rows of granules; female pectines with 13-14 teeth. Th e new species can be distinguished from other known species of the genus from the Atlantic forest region of
Brazil
, and in particular from
A. mauryi
, which is also distributed in the State of
Bahia
by: (i) a less dark pigmentation of the body and appendages; chelicerae in the new species are totally covered by reticular pigmentation, whereas in
A. mauryi
these cover only the anterior and lateral edges, (ii) pedipalp fingers with have 6 rows of granules instead of 7 as in
A. mauryi
, (iii) female pectines with 13-14 teeth, in contrast to 15-16 as in
A. mauryi
, (iv) some distinct morphometric values (see
Table I
). Th e new species is possibly an endemic element to the Atlantic forest formation.
Etymology
.
Patronym is in honor of Dr. Adriano Brilhante Kury of the Museu Nacional (UFRJ),
Rio de Janeiro
,
Brazil

Description
.
Based on female
holotype
(measurements in
Table I
).
Coloration
.
Generally yellowish with dark brown pigmented zones on the body and its appendages. Prosoma: carapace yellowish with brownish spots on the central zone, lateral and posterior edges; anterior edge with two conspicuous yellow zones; eyes surrounded by black pigment. Mesosoma: yellowish with intensely marked confluent brownish zones on the posterior and lateral edges of tergites. Metasoma: segments I to V yellowish; all segments intensely marked with light brown spots. Vesicle yellowish without spots; the base of the aculeus yellowish and the tip light reddish. Venter yellowish; sternites with diffused brownish confluent spots. Chelicerae yellowish with variegated blackish spots over the entire surface; fingers with blackish spots; teeth reddish. Pedipalps: yellowish; femur and patella with dispersed blackish-brown spots; chela hand almost entirely blackish-brown; fingers dark. Legs yellowish, with several blackish-brown spots.
Morphology
.
Carapace with thin but intense granulation; anterior margin not emarginated, almost straight. Anterior median superciliary and posterior median carinae weak or absent. All furrows moderate to weak. Median ocular tubercle distinctly anterior to the centre of the carapace; median eyes separated by approximately 0.8 of one ocular diameter. Three pairs of lateral eyes. Sternum subpentagonal. Mesosoma: tergites with moderately strong and intense granulation. Median carina moderately marked in all tergites. Tergite VII pentacarinate. Venter: genital operculum divided longitudinally, each plate more or less suboval in shape. Pectines: pectinal tooth count 13-13; basal middle lamellae of the pectines not dilated; fulcra absent. Sternites almost smooth; only VII is slightly granular; stigmata moderately elongate; setation weak; sternite VII with four weakly marked carinae. Metasoma: segments I to III with 10 carinae, crenulate. Segment IV with 8 carinae, crenulate. Intercarinal spaces slightly granular. Segment V slightly rounded with 5 carinae. Telson elongated and without granulations; with one ventral carina weakly marked; aculeus moderately short and

weakly curved; subaculear tooth strong and spinoid. Cheliceral dentition characteristic of the family
Buthidae (
Vachon 1963
)
; fixed finger with two moderate basal teeth; movable finger with two weak basal teeth; ventral aspect of both finger and manus with dense, long setae. Pedipalps: femur pentacarinate; patella and chela with vestigial carinae; internal face of patella with 4/5 minute spinoid granules; all faces smooth. Fixed and movable fingers with 6 almost linear rows of granules; two small external and one internal accessory granule present at the base of each row; three granules in the extremity of the fingers; Trichobothriotaxy; orthobothriotaxy A-ss-beta (
Vachon 1974
,
1975
). Legs: tarsus with very numerous fine median setae ventrally. Tibial spurs strongly developed on leg IV; moderate on leg III.
