Type series: Holotype male, MD 11 c, Anjozorobe (Antananarivo), Ravoandrina, Rivière Ampanakamonty near campsite, 1280 m asl, 12.8 °C, 78 µS/cm, 21.07.2001, mounted; paratype, same locality and date, 0/1/0 mounted.
Habitat: Stream at 1280 m asl.
Distribution: Madagascar (Central Highland).
Derivatio nominis: Anjozorobe; according to the only sample site of the species near the village of Anjozorobe.
Diagnosis: Integument lined; dorsal plate bears Dgl-3 to -5 and post-ocular setae in both sexes (additionally Dgl-6 and Lgl- 4 in males); coxal field and secondary sclerotization of Cx-IV and post-genital sclerite fused to extended, unified ventral shield; suture lines of individual coxae still clearly visible; Cxgl-2 between Cx-II and Cx-III; Vgl-2 and -4 free on separate platelets; Cx-I medially fused, Cx-III medially approximate to each other; genital field rectangular pear-shaped, acetabula mid-sized, elongated-oval, touching each other; sub-terminal seta on leg-IV-6 mid-sized, inserted relatively far proximal; capitulum stout, ventral margin convex; palp compact, P4 distally swollen.

Description, male (n = 1): Idiosoma rounded-oval ( Fig. 98 View FIGURES 98–105 ); dorsum mainly covered by large plate (L/W 693/441), including Dgl-3 to -6, Lgl-4 and post-ocular setae, colour greyish dark-purple; lateral eyes separated on each side, free under soft integument, anterior eyes irregularly shaped, posterior eyes oval; soft integument around dorsal plate lined, bearing Dgl-2, Lgl-1 to -3 on small platelets, one pair of very small platelets above anterior eyes ( Fig. 100 View FIGURES 98–105 ), and l1-5 ( Fig. 99, 100 View FIGURES 98–105 ); coxal field and secondary sclerotization form unified ventral shield (L/W 683/567); Cx-I medially fused (rostral 1/3 of medial margin free), postero-lateral margin of Cx-II overlap Cx-III; Cx-III medially approximate each other; coxal field medially fused by fine secondary sclerotization; suture line between Cx-III and Cx-IV straight; medial and latero-caudal margin of Cx-IV straight to slightly convex, caudal corner rectangular with hook-like notch, insertion of leg-IV anterior to genital field ( Fig. 98 View FIGURES 98–105 ); Cx-IV laterally fused with secondary sclerotization without visible margin ( Fig. 98 View FIGURES 98–105 ); genital bay rostral very narrow; genital flaps rectangular-rounded, caudally broadened ( Fig. 98 View FIGURES 98–105 ); acetabula mid-sized, oval, touching each other, Ac1 slightly distant from anterior, Ac3 from posterior margin of genital flaps; pre- and post-genital sclerites completely fused with secondary sclerotization; setae of Vgl-1 lateral of caudal margin of genital field, Vgl-3 approximate to latero-caudal margin of Cx-IV; Vgl-2 and Vgl-4 on platelets posterior to distinct caudal margin of ventral shield (platelets of Vgl-2 laterally extended); excretory pore without sclerotization ( Fig. 98 View FIGURES 98–105 ); leg segments relatively short; claws on leg-I to -III with well developed ventral and smaller dorsal clawlet ( Figs 101, 102 View FIGURES 98–105 ), leg-IV-6 without claws, short, distally tapering, rounded, subterminal seta mid-sized (only socket visible in mounted specimen) ( Fig. 103 View FIGURES 98–105 ); capitulum very short, stout, ventral margin convex ( Fig. 104 View FIGURES 98–105 ), palps relatively compact, ventral seta at P2 more laterally, five dorsal setae, ventral margin irregular, P3 with two latero-dorsal and two medio-dorsal setae, P4 compact club-shaped distally, P5 short with large terminal claws ( Figs 104, 105 View FIGURES 98–105 ).
Female (n = 1): Less sclerotized than male ( Fig. 106 View FIGURES 106–111 ); dorsal plate larger (L/W 735/536), bearing Dgl-3 to -5 and post-ocular setae; Lgl-4 on separate platelets lateral to dorsal plate, Dgl-6 on irregular platelets posterior dorsal plate, two pairs of small platelets anterior to Lgl-4 and posterior to Dgl-6 ( Fig. 107 View FIGURES 106–111 ); coxal field compacter, Cx-I medially completely fused, capitular bay shallower, caudal margin of Cx-IV oriented more laterally, insertions of legs-IV lateral to genital field, ventral shield broad, less extended (L/W 662/672), caudally only reaches half way between genital field and excretory pore, Vgl-2 and -4 ( Fig. 106 View FIGURES 106–111 ); leg-II as in male ( Fig. 108 View FIGURES 106–111 ); distal segments of leg-IV slenderer ( Fig. 109 View FIGURES 106–111 ); gnathosoma as in male, chelicera compact, proximally high, claw very broad ( Figs 110, 111 View FIGURES 106–111 ).
