Mesabolivar aurantiacus (Mello-Leitṳo, 1930)

Figs 594–596 , 1047

Synonymy, see Huber 2018: 29.

Notes

In a recent revision of the genus Mesabolivar , the female paratypes of Mesabolivar pseudoblechroscelis González-Sponga, 1998 were said to be misidentified M. aurantiacus (Huber 2018: 29) . This was an error. In fact the females are M. eberhardi Huber, 2000 (as already noted by Machado 2011; see below).

The male holotype of Autana autanensis González-Sponga, 2011 (synonymized with M. aurantiacus in Huber et al. 2014a ) was reexamined, MIZA 105667 (MAGS 1162). The coordinates in the original publication specify a locality at approximately 800 m a.s.l., while the publication gives an altitude of 250 m. The Rio Autana joins the Rio Sipapo at 4.745° N, 67.698° W, at approximately 100 m a.s.l. The collecting site was thus probably further upstream, maybe at approximately 4.75° N, 67.65° W.

New records

VENEZUELA – Bolívar • 4 ♂♂, 4 ♀♀, ZFMK (Ar 21965), and 1 ♂, 1 ♀ in pure ethanol, ZFMK (Ven18- 170), La Neverita (8.0970° N, 62.6727° W), 225 m a.s.l., 13 Nov. 2018 (B.A. Huber, O. Villarreal M.) • 6 ♂♂, 6 ♀♀, CAS (9027301, 311, 320), Río Caura , Campamento Cecilia Magdalena [approximately 6.3° N, 64.5° W, 250 m a.s.l.], 12 Apr. 1957 (collector not given), 30 Apr. 1957 (C. Sincole, D. Robayna) .

Distribution

This species is widespread in northern South America (cf. fig. 724 in Huber 2018); in Venezuela only in the states Amazonas and Bolívar. The map in Fig. 1047 suggests that the species is also present in Delta Amacuro.
