Nhandu chromatus Schmidt, 2004
Adult female from unknown locality (not examined).
Adult male from unknown locality.
Left male palpal bulb with PS, R, A and SA keels, retrolateral view.
Left male palpal bulb with PS, PI, A and SA keels, prolateral view.
Notes: Male specimen was examined. Plumose stridulatory hairs on prolateral face of coxa I are absent (unlike the genus Lasiodora). Male palpal bulb with PS, PI, A, SA and R keels, subapical keel (SA) is triangular, R keel is denticulate in figured specimen but can be also smooth. Presence of two tibial apophyses. Long ventral tibial apophysis basally incrassate, apically bent with dorsal subapical spine, short prolateral tibial apophysis with 3 inner spines, short and joined. Presence of plumose hairs on prolateral face of coxa I, trochanter I and femur I (in pad), further on retrolateral face of palpal coxa (apically), trochanter (in pad) and femur. Presence of scopula on femur IV retrolaterally. All tarsi integral. Numerous labial and maxillary cuspules. Palpal tibia with about 15 spines on prolateral face. Presence of three visible pairs of sternal sigilla near coxa I, II, III. Presence of claviform trichobothria on dorsal face of all tarsi. Presence of modified type I urticating hairs. This species lacks very long, curly, scattered hairs on carapace which are typical for the genus Nhandu (Bertani, 2001), the genus which is closely related to Vitalius Lucas, Silva Jr. & Bertani, 1993, Proshapalopus Mello-Leitao, 1923, Eupalaestrus Pocock, 1901 and Lasiodorides Schmidt & Bischoff, 1997.
This species was eroneously placed in Lasiodora cristata (Mello-Leitao, 1923) as Vitalius cristatus by Schmidt (1998) and Baumgarten (1998) from which it differs by absence of plumose stridulatory hairs on coxa I.
Lasiodora cristata (Mello-Leitao, 1923) possesses the stridulatory hairs on the prolateral face of anterior coxae which is a synapomorphy of the genus Lasiodora (Bertani, 2001). This species was originally described in the genus Acanthoscurria, then transferred to Pamphobeteus by Schiapelli & Gerschman, 1964.
