Description of ad. Rc 6483 [data on sad. Rc 7155 in square brackets where it differs].

Length ca. 30 [15] mm. Coloration in alcohol uniformly yellow [greyish] with head visibly darker [head, body (including sternites) and ultimate legs with small aggregations of dark pigment, Figs 33, 34 View FIGURES 30–36 ]; numerous small setae at all body surface.

Head ( Fig. 35 View FIGURES 30–36 ) with much shortened anteriorly (as long as ½ [1/3] of head), but well-developed [indefinite] paramedian sutures; very short antennae (left 15, right 17 articles [both 17]) hardly extending to the posterior margin of tergite 1 [2] when reflexed.

Forcipular coxosternite ( Figs 36, 33 View FIGURES 30–36 ) with two much shortened posteriorly (as long as 1/2 [1/3] of coxosternite) and converging anteriorly typical longitudinal sutures; transverse suture absent. Tooth-plate with 4 teeth, of these the most lateral and the most median ones are approximately of the same length, being much shorter than 2 remaining teeth; long and pointed trochanteroprefemoral process with one lateral tubercle.

Tergites 1–20 with complete paramedian sutures; tergite 21 ( Fig. 38 View FIGURES 37–42 ), with complete median suture [plus a median depression in the posterior half], only this tergite is marginated laterally.

Sternites 2–20 with complete paramedian sutures disposed in paramedian sulci; sternite 21 ( Fig. 38 View FIGURES 37–42 ) trapeziform, slightly [noticeably] longer than wide, its posterior margin rounded [straight]; sternite 21 with a short, shallow median sulcus / depression in the posterior third.

Legs with 2 short [minute] but clearly recognizable [hardly recognizable] pretarsal accessory spines.

Ultimate LBS ( Fig. 37 View FIGURES 37–42 ): coxal pore field as long as [very slightly longer than] sternite 21, coxopleuron slightly longer than sternite 21, with rounded posterior margin, lacking either any process or spines [the only minute spine at the very inner corner of the coxopleuron].

Ultimate legs ( Figs 37, 38 View FIGURES 37–42 ): prefemur, femur and tibia much flattened dorsally. These articles are each with characteristic dorso-medial longitudinal depression apically; tibia and tarsus 1 somewhat swollen / bulbous ventrally. Prefemur with the only spine at the position of the corner spine ( Fig. 38 View FIGURES 37–42 ) [prefemur ( Fig. 34 View FIGURES 30–36 ) with 3 unusually large dorso-medial spines—2 of them disposed at a remarkably enlarged corner spine—plus 1 ventro-medial and 1 medial one, both of the latter are disposed at the distal margin of the prefemur, forming a transverse row together with the corner spine; no any ventral spines].

Remarks. Adult spm Rc 6483 has been mentioned by Schileyko (2002) as C. brasiliensis Humbert & Saussure, 1870 but the present re-investigation shows that it is C. ungulatus , because it shares with the latter such important peculiarities of the forcipular coxosternite as very short paramedian sutures plus a total absence of a transverse one. This specimen also has no paired dorso-distal “bifid spines” on the ultimate femur (!), which should be diagnostic for C. brasiliensis (see Chamberlin 1914: 183) and being very unusual (if not unique) within Cormocephalus ; Lewis (1989: 1006) wrote that C. brasiliensis “was described on the basis of a defective specimen”.
