Diagnosis Distinguished from known congeners by shape of procursus ( Figs 40, 41; distinctive distal elements); from A. atewaalso by unpaired process on male clypeus ( Figs 36, 42; paired in A. atewa); from other species also by more pointed apophyses frontally on male chelicerae ( Fig. 42). Females in this genus are difficult to distinguish (except A. atewa, which has the epigynal pockets more anteriorly).
Etymology Named for Cameroonian filmmaker Daniel Kamwa (born 1943), director of the 1981 film Notre Fille.
Typematerial Holotype ♂, in ZFMK( Ar 11931). Typelocality CAMEROON, Northwest Region, near Bamenda, under trash and logs at roadside( 6°00.5’N, 10°18.1’E), 1750 ma.s.l., 16 Apr. 2009( B.A. Huber). Other material examined CAMEROON: Northwest Region: 1 ♂, 1 ♀in ZFMK( Ar 11931), same data as and together with holotype; 1 ♂, 1 ♀, 2 juvsin pure ethanol, in ZFMK( Cam 76), same data.
Description 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. 36); 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. 35; ocular area not elevated; carapace without median furrow; clypeus with rounded median process at rim ( Fig. 42); sternum wider than long (0.48/0.36), unmodified. Chelicerae as in Fig. 42, with pair of lateral processes proximally and pair of pointed distal frontal apophyses without modified hairs; without stridulatory ridges. PALPS. As in Figs 37-38and 40-41, 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 intwo other males: 1.37, 1.67. Female 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. 39), internal structures visible through cuticle; internal genitalia as in Fig. 43.
Distribution Known from typelocality in Cameroon only ( Fig. 20). A poorly preserved male specimen from eastern Cameroon (Mbam near Koupoupi, MRAC 167.984) may also belong to this species.
