Allocladius salti Ferrington Jr & Saether 2011, comb. n.

Description

Allocladius salti (Freeman) comb. n.

(Fig. 19 G)

Pseudosmittia salti Freeman, 1954: 442, pro parte.

Smittia nigra, Freeman, 1956: 349, pro parte, not Kieffer 1913: 28, not Freeman, 1953: 206.

Allocladius niger (Freeman); Freeman & Cranston 1980: 181, pro parte, not Kieffer 1913: 28.

Material examined: TANZANIA: Kilimanjaro, Shira Plateau, sweeping bog grass at 12,100 feet, holotype male, 27.xi.1948, G. Salt (495)(BMNH).

Diagnostic characters: The male imago can be separated from other species with more than 3 acrostichals, supraalar setae, large superior volsella and with large lobe-like accessory lobe of the inferior volsella by having R 4+5 ending far proximal of the end of M 3+4 and an AR of about 0.84.

Male imago (n = 1)

All measurements and ratios are within the variation of A. aizaiensis with the following exceptions: Total length/wing length 1.54; wing length/length of profemur 3.11; AR 0.84; terminal flagellomere 333 µm long; tentorium 151 µm long; stipes 139 µm long; 5 prealars; VR 1.41; no costal extension; R 4+5 ends far proximal of end of M 3+4; BV 3.70; BR 1 4.2; gonostylus 64 µm long; HR 2.89; and HV 3.63.

Remarks

Freeman (1954: 442) described a mixed collection of A. salti and A. niger. There is a female, which we have not examined with the same data as the holotype in the BMNH. However, since we do not have an associated female of A. niger we would not be able to assign that female to a species.

Distribution

The species is known with certainty only from the type locality in Tanzania.
