2.2.5 Dinidoridae Stål, 1868

The Dinidoridae represents another family that was treated by most early workers as a subfamily of
the Pentatomidae. Amyot and Serville (1843) recognized the group Mégyménides, including only
Megymenum Guérin-Méneville, as a group within their tribe Coniscutes. Stål (1868) proposed the group
Dinidorida to include the genera Aspongopus Laporte (= Coridius Illiger), Atelides Dallas (= Sagriva
Spinola), Dinidor Latreille, and Megymenum; he later (Stål 1870) gave the group subfamilial status, a
classification that most workers followed until the 1950s. The main exception was Lethierry and Severin
(1893) who catalogued this group as a family. Cachan (1952), in his monograph of the Madagascar fauna,
treated this group as a family. Although the name Megymeninae has priority over the Dinidoridae, the
latter family has been well established and should not be supplanted (see article 35.5 of the International
Code of Zoological Nomenclature [ICZN]); the Megymeninae is retained as a subfamily within the
Dinidoridae.
The most recent authoritative work on the family was by Durai in 1987 who also treated this group
at the family level; earlier, this family was treated in a still useful paper by Schouteden (1913). Durai
(1987) established the presently used classification (with a couple updates - see below), and provided
