Polynema (Polynema) dikobraz Triapitsyn, 2017 


Holotype ♀ examined, dissected under 4 coverslips on slide and almost complete (lacking a radicle of one antenna): MADAGASCAR, Prov. D’Antanarivo 3 km 41°NE Andranomay, 11.5 km 147° SSE Anjozorobe, el. 1300 m 5-3.xii.2000, 18°28'24"S, 47°57'36"E, Fisher, Griswold et al. California Academy of Sciences Montane rainforest, MT, coll code BLF2372, CAS LOT # 005501, Mounted at UCR/ERM by V.V. Berezovskiy 2011 in Canada balsam, Polynema (Polynema) dikobraz  Triapitsyn HOLOTYPE ♀, Det. by S.V. Triapitsyn 2011 ( CASC).


Morphologically similar to the newly described species, P. sagittaria  sp. n., both species having enlarged spine-like microtrichia. Polynema dikobraz  , however, has a normal ovipositor, and is closely related to an undescribed species, from which it can be separated by the length of the modified wing spine and relative length of the first antennal flagellar segment.


Based on the hypothesized morphological synapomorphy of modified (long, thick) microtrichia on the fore wing disc, P. dikobraz  is related to P. sagittaria  sp. n., but has far fewer, and longer modified wing disc microtrichia. This species also has a normal ovipositor as in other members of Polynema  , as opposed to the highly modified ovipositor of P. sagittaria  .
