Comments

This species was originally described as Ceraphron origenus by Kieffer (1913b) from a series of male and female specimens. According to Dessart (1966a), the original syntypic series consisted of five females and one male. However, upon reviewing the specimens himself, Dessart found that the six specimens actually belonged to three different Aphanogmus species ( Dessart 1966a).

Dessart identified the male and one female specimen as Aphanogmus fumipennis based on antennal characters and the male genitalia ( Fig. 6 ). He made a slide preparation (prép. no. 6505/06) of the male metasoma and genitalia (MNHN EY22435), and appears to have left the remaining bleached fragments of the male in an ethanol vial with the female specimen (MNHN EY25350).

In looking at the other syntypes, Dessart found that three of the remaining females belonged to the same species ( Fig. 7 A–B). Rather than synonymize Ceraphron origenus with Aphanogmus fumipennis , he chose a lectotype and paratypes from these three females to represent a new combination, Aphanogmus origenus , then re-described the species and noted that the male is unknown ( Dessart 1966a). He dissected the female lectotype and made two slide preparations (prép. no. 6504/261), with one slide containing the left antenna (MNHN EY22436), and the other containing the left fore wing and hind wing (MNHN EY22437). The rest of the female lectotype is stored in an ethanol vial (MNHN EY25358). Two female paralectotypes are stored together in another ethanol vial (MNHN EY25352). These two specimens were not imaged.

The state of the last female paralectotype remains uncertain ( Fig. 7C ). Dessart (1966a: 11) provided the following comments: “également dépourvue de rebord périphérique au scutellum mais à antennes non massuées, représente sans doute une nouvelle espèce malheureusement en trop mauvais état pour être bien décrite”. Dessart determined that the specimen was an Aphanogmus and not a Ceraphron , and based on differences in the antenna and scutellum, thought that the specimen could represent a new species. However, he thought the specimen’s condition was too poor to describe a new species from. The specimen currently remains in ethanol (vial MNHN EY25357).

None of the specimens have locality labels, though Dessart’s labels for ethanol specimens MNHN EY25358 and MNHN EY25350 quote a determination label from Kieffer that indicate “ Type 71”.
