Thaumatogelis gallicus (Seyrig, 1928)

Thaumatogelis gallicus also has the second and third tergite entirely fused. Its metasoma is entirely black except for the first tergite. The ovipositor is long (0.8–1.2× hind tibiae) and simple and the sixth tergite of the metasoma does not cover the seventh tergite entirely. The third antennal segment is 2.4–2.7× as long as wide. Its head is black and somewhat narrowed ( SCHWARZ, 2001). Its mesosoma is reddish, making it easy to recognise by habitus (in combination with the mentioned characteristics). Another aspect that distinguishes this species from many other specialists of spiders are its observations in houses and urban areas. One of its hosts is the common house spider Eratigena atrica (C.L. Koch, 1843) ( Araneae : Agelenidae ) ( SCHWARZ & SHAW, 2000). The species has many reports in Belgium, while it seems to be more uncommon in the Netherlands. It is unclear why this is the case at this moment.

First report for the Netherlands; confirmed in Belgium.
