Type species: Ischyrodyodoys thomsonae sp. nov.
Diagnosis. The tarsal formula 4-5-5 and the form of the mouth parts indicate that this genus belongs to the tribe Athetini . With the ligula separated in 2 lobes wide at the base, the new genus is taxonomically close to Aloconota Thomson, 1858 , but in the new genus the lobes are much broader, fig. 20, than those of Aloconota , fig. 14, and have an apical bristle, absent in Aloconota . The lacinia of the maxilles finishes in 2 strong canine teeth, fig. 23, not as in Aloconota , fig. 7. The anterior border of the mentum, fig. 21, is deeply arched in the new genus. In addition, the tapered form of the body in the new genus, is clearly different from that of the species of Aloconota .
Description. 11 antennomeres, pronotum more narrow in front than posteriorly, abdomen very narrow posteriorly. Labial palpus 3-jointed, ligula separated in 2 lobes with wide base and with a apical bristle, fig. 20, maxillary palpi 4-jointed, maxillae with 2 strong canine apical teeth of the lacinia, galea as long as the lacinia,with pubescent apical membrane, fig. 23. Trapezoidal mentum, with smaller base deeply arched posteriorly, fig. 21. Mesosternal process insinuated between the mesocoxae, which are slightly separated. Tarsal formula 4-5-5, 1st mesometatarsomere as long as the 2 following tarsomeres together. Aedeagus figs 17–18, spermatheca fig. 19.
Etymology. The name of the neutral grammatical genus of the new genus means “Two strong teeth” from the ancient Greek ίσχυρος = strong, δύο = two and όδούς = tooth.
