Chimarra maai Cartwright 2020, sp. nov.

Description

Chimarra maai sp. nov.

Figures 155–157

Holotype. Male (dried, pinned specimen CT-377 figured), Indonesia, Papua Province, Bodem, 11 km south-east of Oerberfaren, 100 m, about 1° 58' S, 138° 44' E, 7–17 Jul 1959, T.C. Maa (BPBM).

Diagnosis. The male of C. maai can be separated from all other New Guinea species, including C. pinga Cartwright, by the combination of the field of small, dark spines at the apex of the phallus and the shape of the inferior appendages, which are narrowed at about the middle, in lateral view.

Description. General body colour and wings light brownish (badly damaged).

Male. Segment IX anterior margin in lateral view, anteroventrally weakly angled (fig. 155), ventral process on segment IX, not discerned (specimen slightly damaged?; figs 155, 156), preanal appendages relatively large, laterally compressed, rounded in lateral view (fig. 155), in dorsal view appear sub-triangular (fig. 157). Segment X lateral lobes laterad of phallus, robust, apices widely rounded, sensilla not discerned. Phallus with one slender spine included subapically (figs 155–157). Inferior appendages broadest in basal half, narrowed near midlength, slender in distal half, apices acute, directed posteriorly (figs 155, 156), in lateral view angled at about 60° to horizontal, length about 3.5 times width, dorsal margin almost straight, ventral margin slightly convex in basal half and straight in distal half (fig. 155), in ventral view mesal and lateral margins slightly curved (fig. 156).

Female. Unknown.

Etymology. Maai – named for T.C. Maa (collector).

Remarks. Chimarra maai is known only from Papua.
