Demitergite sensillar formula by half tergum from Th I to Abd VI as 022/111110. Ratio microseta: sensilla = 1: 6. Th I with 4 + 4 dorsal microsetae and 1 lateral. Th II to Abd V demitergites Di/De/DL fields with 33/33342; De 44/3333; DL 22/4445 setae, respectively. Th II-III chaetotaxy similar, with 3+3 setae on a row (a1, a4 and a6), 4+4 on m row (m4, m5-m7) and 4+4 on p row (p1, p2, p4, p5); Th. II-III sensorial sensilla as p4 and m7; lateral microsensillum (ms) present on Th II. Abd I-III chaetotaxy similar, with 3+3 setae on a row (a1, a4 and a6), 3+3 on m row (m2, m4-m7) and 5+5 on p row (p1, p4, p5, p6), sensorial setae as p5. Abd. IV chaetotaxy with 3+3 setae on a row (a1, a4, a6), 3+3 on m row (m1, m2, m4) and 5+5 on p row (p1, p2, p4, p5, p6), sensorial setae as p5.

Three anal vesicles (Fig. 24 View Figure 24 ).

Etymology

The name is locative, after of the country where it was collected in Peru.

Molecular results

DNA was successfully obtained from four specimens of N. peruana   sp. n., sequences are BCICL099-19, BCICL101-19, BCICL102-19 and BCICL103-19, which were deposited in the project BCICL of the Barcode of Life Data System (http://www.barcodinglife.org/index.php). The Barcode Index Number for this species is BOLD:ADS2464 (hyperlink activated as https://www.boldsystems.org/index.php/Public_BarcodeCluster?clusteruri=BOLD:ADS2464).

The cuticles of four specimens were recovered and mounted in Hoyer’s solution which represent the vouchers and are kept at the author’s institution.

Diagnosis

Neotropiella peruana   sp. nov. is characterised by the combination of a ventral sensorial field on Ant IV with about 100 modified setae, small body size (1.2-2.2 mm) and small number of vesicles in the postantennal organ (26-28 in average). Mandibles have 4 teeth and maxillae with 2 lamella, 1 acuminate and 1 hooked. Th I with 4 pairs of smooth microsetae and Di area on Th II and III with 3 setae. 1 + 1 lateral tooth on unguis besides the inner 1 and often 1 + 1 subapical tooth.
