MALE: Unknown.

FEMALE (PBI_OON 3483, figs. 47–53): Total length 1.97. Carapace pale orange, sides finely reticulate. ALE largest, separated by their radius to diameter; posterior eye row procurved from front. Sternum, mouthparts pale orange. Dorsal scutum pale orange, covering half to 3/4 of abdomen length, more than half to most of abdomen width. Postepigastric scutum pale orange, with short, posteriorly directed lateral apodemes. Legs pale orange, without color pattern. Leg spination: patella I v1p-1r-2; tibiae: I, II v2-4-0; IV v0-0- 1p. Genital atrium small, triangular, with transverse sclerotization; anterior receptaculum short, wide, with rounded tip; posterior receptaculum elongated, distally curled, with substantial terminal squiggle.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Cameroon.

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Female can be recognized by the darkened, almost parallel lateral margins of the posterior receptaculum, which has a simple curl at its posterior end (figs. 59, 60).

MALE: Unknown.

FEMALE (PBI_OON 3485, figs. 54–60): Total length 1.99. Carapace pale orange, sides finely reticulate. Eyes subequal, ALE separated by more than their diameter; posterior eye row straight from front. Sternum, mouthparts pale orange. Dorsal scutum pale orange, covering half to 3/4 of abdomen length, more than half to most of abdomen width. Postepigastric scutum pale orange, without posteriorly directed lateral apodemes. Legs pale orange, without color pattern. Leg spination: patella I v0-1p-1r; tibiae: I v2-4-0; II v1r-2-0; IV v0-0-2. Ovoid atrium present between weakly invaginated edges of epigastric and postepigastric scuta, no transverse sclerotization obvious, sides of posterior receptaculum darkened, almost parallel.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Cameroon.

Triaeris menchum, new species

Figures 61–67

TYPE: Female holotype taken in a forest at an elevation of 2150 m at Lake Oku, 6°12′N, 10°27′E, Menchum Division, North-West Province, Cameroon (Feb. 7–13, 1992; C. Griswold, S. Larcher, N. Scharff, C. Wanzie), deposited in CAS (PBI_OON 3486).

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Females can be recognized by the leaf-shaped sclerotizations at the sides of the posterior receptaculum (figs. 66, 67).

MALE: Unknown.

FEMALE (PBI_OON 3486, figs. 61–67): Total length 2.29. Carapace pale orange, sides finely reticulate. Eyes subequal, ALE separated by more than their diameter; posterior eye row procurved from front. Sternum, mouthparts pale orange. Dorsal scutum pale orange, covering less than half of abdomen length, less than 1/4 of abdomen width. Postepigastric scutum pale orange, without posteriorly directed lateral apodemes. Legs pale orange, without color pattern. Leg spination: patella I v0-1p-1r; tibiae: I v2-4-0; II v1r-1r-0; IV v0-0-2. Genital atrium represented only as narrow slit; posterior receptaculum globular, with leaf-shaped lateral sclerotizations.

OTHER MATERIAL EXAMINED: One female with the same data as the holotype, “beneath rocks and logs” (CAS PBI_OON 3482). DISTRIBUTION: Cameroon.
