NOTE: Although cribellate, this species was originally described in the clubionid genus Chemmis Simon (1898 , currently considered a junior synonym of the corinnid genus Megalostrata Karsch, 1880 View in CoL ), and was subsequently transferred to the genus Anachemmis Chamberlin View in CoL by Roewer (1955). Examination of the holotype female indicates that Banks’ original placement, and Roewer’s transfer, are both incorrect. Banks noted that ‘‘In front of spinnerets is a curious truncate lip.’’ This apparently refers to the anterior edge of the cribellum, most of which is folded against the anterior lateral spinnerets and therefore not readily visible in ventral view. Had Banks noted the cribellum, he would presumably have placed the species in a cribellate family rather than the Clubionidae View in CoL ; the misplacement was no doubt abetted by the scopular setae obscuring the remnant of the third claw and making the spider appear to be a dionychan. It seems that Lehtinen (1967) detected these misplacements, for he presented genitalic illustrations of the species under the combination Zorocrates unicolor View in CoL ; since Lehtinen did not mention the author or original combination of the name, the combination presented in his figure legend was enigmatic and appeared to be just a nomen nudum ( Platnick, 2006). The species is here formally transferred to Zorocrates View in CoL .

DIAGNOSIS: Males resembles those of Z. fuscus but have a shorter, ledge-shaped (rather than fingerlike) proximal lobe on the retrolateral tibial apophysis, a distally widened median apophysis with a large, prolaterally directed denticle ( figs. 7, 8 View Figs ), and a ventrally longer tegular apophysis. Females also resemble those of Z. fuscus but have much larger openings to the epigynal pockets ( fig. 9 View Figs ).

Retrolateral tibial apophysis short, with distinctly ledge-shaped proximal lobe; median apophysis distally angular; tegular apophysis sharply pointed ( figs. 6–8 View Figs ).

FEMALE: Total length 15. Coloration as in Z. fuscus . Leg spination: femora: I, II p0-1-1, r1- 1-0; IV p0-1-1, r0-0-1; patellae: III r0-0-0; IV p0- 0-0; tibiae: I, II d0-0-0, p0-0-0, r0-0-0; III r1-0-1; metatarsi: I p0-0-0, v2-2-2, r0-0-0; II p0-0-0, r0-0- 1; III p1-1-2, r1-2-2. Cribellum present. Epigynal midpiece broadly triangular, lateral pockets large; spermathecae relatively wide ( figs. 9, 10 View Figs ).

THE BADIUS GROUP

The six species assigned to this group are united by the presence of a narrow epigynal septum surrounded posteriorly by a pair of elevated lateral margins. Males are known for only four of the species, but they share a median apophysis that is elongated and obliquely oriented.
