Randia pseudozosterops Delacour & Berlioz, 1931 —Rand’s warbler ( Bernieridae ). Type locality. Ranomafana National Park , Fianarantsoa , Madagascar ( 21.25628 S , 47.4218 E ) . Diagnosis. Aratricerca madagascariensis n. sp. is most similar to Aratricerca cerata n. sp. To distinguish these two species, see diagnosis of A. cerata , above. Description. Male. Head as in Fig. 16 , with straight lateral margins of preantennal area. Frons flattened, slightly concave. Dorsal anterior plate with broad sublateral thickening as in Fig. 16 . Ventral anterior plate absent. Head chaetotaxy as in Fig. 16 . Coni short. Gular plate broadly triangular, with irregular lateral margins. Thoracic and abdominal segments and chaetotaxy as in Fig. 15 ; ss of segment II obscured by gut content in holotype , and have here been illustrated tentatively; 2 ps on each side of segment VI; tail with 1 dorsal and 1 ventral setae on each side. Subgenital plate does not reach distal end of abdomen. Tail of abdominal segment XI with sclerotised distal margin. Basal apodeme ( Fig. 17 ) broad, slightly constricted at mid-length; anterior end rounded. Proximal mesosome ( Fig. 19 ) rounded, and widening; mesosomal lobes angular; section distal to gonopore densely papillate marginally; 2 gpmes sensilla on each side of gonopore; gonopore as in Fig. 19 . Parameral heads ( Fig. 18 ) large, bifid; parameral blade with lateral modification as in Fig. 18 ; pst2 sensilla on terminal end. Measurements (n = 1): TL = 2.32; HL = 0.38; HW = 0.31; PRW = 0.23; PTW = 0.25; AW = 0.30. FIGURES 15–19.
