Tribe Holoneurini Enderlein, 1936

The tribe is characterized by synapomorphies characteristic of the valid tribe rank in Porricondylinae ( Mamaev, 2001; Fedotova, Sidorenko, 2007): antennae with 10–11 flagellomeres; reduction of wing venation; absent or reduced parameres; tarsal claws narrow and curved near midlength; male and female flagellomeres with dense sensorial reticulation, and female flagellomeres with a long neck. Their wing venation is variable, with M 3 absent or slightly visible, Cu never forked, CuA 2 slightly visible distally or completely disappearing, m+rm usually slightly curved distally, and rs situated at an angle to R 5. The ovipositor is 2-segmented.

The larvae of some extant species of the Holoneurini have been associated with leaf litter and decaying wood ( Mamaev, Krivosheina, 1965). Adult insects are usually captured in Malaise traps ( Fedotova, Sidorenko, 2005, 2007).

The tribe includes 12 genera and 43 species: 9 extant genera with 38 species (number of species in parentheses): Cassidoides Mamaev, 1960 (8); Coccopsis Meijere, 1901 (8); Cognitepidosis Fedotova et Sidorenko, 2005 (1); Cryptoneurus Mamaev, 1964 (3); Dalaiella Mamaev, 1996 (1); Holoneurus Kieffer, 1894 (14), Melicepidosis Fedotova et Sidorenko, 2007 (1); Putepidosis Fedotova et Sidorenko, 2007 (1), Pyxicoccopsis Fedotova et Sidorenko, 2007 (1) and 3 extinct genera with 5 species: Gratomyia (1), Volnococcopsis (1) and Rovnoholoneurus gen. n. (3).
