Pilarta Bahir & Yeo, 2007

Genus Pilarta Bahir & Yeo, 2007 View in CoL

Type species. Pilarta anuka Bahir & Yeo, 2007 View in CoL , by original designation; gender feminine.

Remarks. Bahir & Yeo (2007: 332, fig. 25C) described the anterior male thoracic sternum as follows: “Suture between male thoracic sternites 2–3 and 3–4 indiscernible …”, figuring sternites 1–4 as completely fused without any trace of sutures. This was repeated in the subsequent generic diagnosis by Pati et al. (2017: 14) who noted that “sutures between male thoracic sternites s2/s3 and s3/s4 indiscernible as grooves.” The figures of the male anterior thoracic sternums of their two new species show a small triangular structure that is the fused sternites 1 and 2, separated from the fused sternites 3 and 4 by a ridge or groove ( Pati et al. 2017: figs. 7g, 9g). The holotype male of P. anuka was re-examined for the present study and the sternite morphology requires further clarification. Sternites 1 and 2 are completely fused to form a triangular structure. Moreover, there is a low rounded ridge that separates these fused sternites from fused sternites 3 and 4. This low ridge is the demarcation between sternites 2 and 3 ( Fig. 4A View FIGURE 4 ) and this was not accurately figured by Bahir & Yeo (2007: fig. 25C). This is the same condition for P. vaman sp. nov. ( Fig. 3D View FIGURE 3 ).
