GENUS CYLOMA SHARP, 1872 View in CoL

( FIG. 12D–H View Figure 12 )

Material examined: Cyloma guttulatus Sharp, 1884: 1 female (NMPC): New Zealand: Fiordland ( FD), Borland Road 24 km NWW of Monowai , baited pitfall traps (rotten squid) in degraded remnants of Nothofagus forest with numerous rotten logs, 45°41.13’S 167°20.29’E, 320 m, 27.i.2016, M. Seidel, V. Sýkora & M. Fikáček lgt. (2016- NZ 024) GoogleMaps .

Cyloma sp. : (undescribed species illustrated in Fig. 12H View Figure 12 ). 1 male, 1 female ( NMPC): New Zealand: Fiordland ( FD), Borland Road 24 km NWW of Monowai, on dead possum, 45°41.13’S 167°20.29’E GoogleMaps ,

320 m, 27.i.2016, M. Seidel, V. Sýkora & M. Fikáček lgt. (2016- NZ 024) .

Karyotype: 2 n = 22 + Xy (♂). In Cyloma guttulatus , chromosome pairs 1–3 and 5 are metacentric, with pair 2 half the size of pair 1, and the others decreasing in size from half the length of pair 2 to about quarter of the size of pair 2 ( Fig. 12D View Figure 12 ). The X chromosomes cannot be identified. Cyloma sp. ( Fig. 12E–G View Figure 12 ) has a similar karyotype to Cyloma guttulatus ; however, autosome pair 2 is about two-thirds of the length of pair 1 and the smallest autosomes, and the X chromosome are about a quarter of the length of pair 1.
