Diagnosis

Paroxystoglossa levigata n.sp. is similar to P. transversa : pronotum with incomplete lamella from lobe to lateral angle, marginal areas of terga are depressed and dark and male gonobase lobes are broadly excavated.Females of P.levigata n.sp. can be separated from P. transversa by the marginal area not punctate and terga with conspicuous row of simple erect setae between disk and marginal area in; the males can be distinguished by fourth sternum with small elevations and fifth sternum with shallow depression.
