Figs 10View Figs 10 - 18, 20View Figs 19 - 20, 35-43View Figs 35 - 39View Figs 40 - 43


Distinguished from known congeners by shape of procursus ( Figs 40, 41View Figs 40 - 43; distinctive distal elements); from A. atewa  also by unpaired process on male clypeus ( Figs 36View Figs 35 - 39, 42View Figs 40 - 43; paired in A. atewa  ); from other species also by more pointed apophyses frontally on male chelicerae ( Fig. 42View Figs 40 - 43). Females in this genus are difficult to distinguish (except A. atewa  , which has the epigynal pockets more anteriorly).


Named for Cameroonian filmmaker Daniel Kamwa (born 1943), director of the 1981 film Notre Fille.

Male (holotype)

MEASUREMENTS. Total body length 1.6, carapace width 0.60. Leg 1: 6.00 (1.50 + 0.20 + 1.63 + 1.90 + 0.77), tibia 2: 1.07, tibia 3: 0.80, tibia 4: 1.20; tibia 1 L/d: 23. Distance PME-PME 45 µm, diameter PME 60 µm, distance PME-ALE 20 µm; AME absent.

COLOR. Carapace ochre-yellow with irregular internal black pigment, sternum light brown with median dark line and four pairs of posteriorly diverging lines ( Fig. 36View Figs 35 - 39); legs ochre-yellow without distinct dark rings; abdomen ochre-gray, with distinct dark heart-mark and thin dark line above spinnerets, dorsally with some white internal spots.

BODY. Habitus as in Fig. 35View Figs 35 - 39; ocular area not elevated; carapace without median furrow; clypeus with rounded median process at rim ( Fig. 42View Figs 40 - 43); sternum wider than long (0.48/0.36), unmodified. Chelicerae as in Fig. 42View Figs 40 - 43, with pair of lateral processes proximally and pair of pointed distal frontal apophyses without modified hairs; without stridulatory ridges.

PALPS. As in Figs 37-38View Figs 35 - 39 and 40-41View Figs 40 - 43, coxa unmodified, trochanter with short ventral apophysis, femur small, with prominent distal apophysis prolaterally, tibia very large, procursus complex, with pointed ventral process, sclerotized retrolateral area set with several stronger hairs, distinctive tip; bulb with only one process (embolus, curved in dorsal view towards prolaterally).

LEGS. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 1 at 27%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with ~10 pseudosegments.

VARIATION. Tibia 1 in two other males: 1.37, 1.67.


In general similar to male but clypeus unmodified; one female with darker chelicerae, clypeus, and sternum; tibia 1: 1.63 (missing in second female). Epigynum simple wide plate with pair of tiny pockets close together near posterior rim ( Fig. 39View Figs 35 - 39), internal structures visible through cuticle; internal genitalia as in Fig. 43View Figs 40 - 43.


Known from type locality in Cameroon only ( Fig. 20View Figs 19 - 20). A poorly preserved male specimen from eastern Cameroon (Mbam near Koupoupi, MRAC 167.984) may also belong to this species.
