Comments

Thomson (1858: 305) described the species Aphanogmus fasciipennis from male and female specimens from Lund, and described a female variation from the same locality that differed in the following regard: “antennarum basi pedibusque testaceis, abdomine. piceo.”. Kieffer (1907b: 199) keyed out the species and also described a female variation of his own with different coloration and antennal characters, collected from “Bitche, en octobre”, which he named radialis .

It is unclear whether the female variations described by Thomson and Kieffer are the same; though Kieffer’s variation was collected from a different locality than Thomson’s, it is described in a similar way, with a lighter coloration on the antenna, legs and abdomen. Kieffer (1914c) later changed his variation to species status. Kelner-Pillault (1958) reported a female found in Kieffer’s collection in Bitche, which was considered a holotype and donated to the MNHN.

Dessart (1963a) redescribed Aphanogmus fasciipennis and briefly discussed the variation Thomson had described. However, the only specimen of the variation Dessart had viewed for this publication was missing from the mount except for a few tarsi, so he was unable to determine if it was actually a different species or not. Dessart did not view the holotype female specimen at the MNHN until 1966, according to the label he placed on the specimen. Dessart dissected the female specimen and made two slide mounts (prép. no. 6605/252), leaving the rest of the specimen on its point mount (MNHN EY25347). One slide contains the anterior left wing and posterior right wing (MNHN EY22466), while the other has the complete left antenna and fragments of the right antenna (MNHN EY22467).

Though Dessart (1966a) discusses several of the MNHN specimens, this specimen is not one of them. It appears that Dessart dissected the specimen in 1966 but then left it out of the final publication. According to Johnson & Musetti (2004), Dessart never published any further papers discussing Aphanogmus fasciipennis or A. radialis . He did add a label to the holotype female at the MNHN commenting “=A. fasc. f. typique!”, but he never officially synonymized it with Aphanogmus fasciipennis Thomson, 1858 ( Johnson & Musetti 2004). While the original specimen bears a holotype label, Dessart did not add any holotype labels to his slide preparations: instead, he marked them with Kieffer’s original determination, Aphanogmus fasciipennis var. radialis .
