Bioacoustics of Psechrus ghecuanus

Remarks: Levi (1982) was the first to illustrate the female copulatory organ of this species. He examined an adult female from Doi Suthep, Thailand and considered it conspecific with the subadult syntypes of P. ghecuanus . As a reason for that, he stated that “The leg proportions were identical...” and “...the recording localities of the mature females from Thailand are close to the type locality in Burma ” ( Levi 1982 ). In the present study eight females and five subadult females were examined. In some cases subadults and adults from exactly the same recording locality. In one case (SB 37) a subadult female was close to adult moult and the epigyne was already fully developed underneath the old cuticle. The pre-epigynes of all five subadults corresponded to those of the syntypes . Moreover, Thorell himself identified adult females from (the present) Kayin Prov. , Myanmar sub P. ghecuanus . This material still exists, was examined for the present study (see SB 820–821 in material list, above) and the epigynes corresponded to the ones of the other females examined herein. So the females examined in Levi (1982 , figs 30–31), Yin et al. (1985) , Song et al. (1999) , Wang and Yin (2001) and in the present study unambiguously belong to P. ghecuanus . Yin et al. (1985) first described and illustrated the male of P. ghecuanus . They identified female Psechrus specimens collected together with —at that time— unknown males from Southern China as P. ghecuanus by using the revision of Levi (1982) . In the present study (among others) material from Chiang Rai Province , Thailand was checked, a subadult female and an adult male from exactly the same locality. As the subadult female could be identified as P. ghecuanus , it is certain, that the males examined in Yin et al. (1985) , in Song et al. (1999) , in Wang and Yin (2001) and in the present study unambiguously belong to P. ghecuanus .
