This genus possesses features found across many other genera. Its general appearance is the same as Itaropsis; genitalia ectoparamere is very similar to Phonarellus; inner tympanum is absent, and particularly, the metanotum is armed with several hairs. Now, we found the first species of Vietacheta in China. The new species, Vietacheta harpophyllasp. nov., is close to Vietacheta aquila Gorochov, 1992, but they are different in details of anal plate, epiphallus, and ectoparamere. A description and illustration of this new species, a revision of other Vietacheta, and a key to the genus are provided.</p>

Volcanic ash has an especially widespread effect on organisms, as it can be dispersed over a greater distance by the wind than are other volcanic products. We examined the effect of volcanic ash on calling songs and mating behavior of the male field cricket Gryllus bimaculatus De Geer (Orthoptera: Gryllidae). Adult males were randomly assigned to one of four treatments comprising different floor material (volcanic ash, filter paper, vermiculite, and Akadama soil), and parameters of calling songs and mating behavior were measured. The dominant frequency of calling song lowered by the volcanic ash. Males reared on volcanic ash and soil exhibited lower calling rates per night. Furthermore, males reared on ash and vermiculite exhibited a longer latency to courtship period than those reared on the other floor materials. Our results showed that floor material does affect the mating efforts of male field crickets.</p>
