status

gen. nov.

Paratractosomus gen. nov.

Diagnosis. Integument very shiny. Frons strongly carinate with anterior margin prominent surpassing frontoclypeal region; antennae serrate with 3 rd antennomere shorter than 4 th; prosternal groove well developed; mesosternal cavity horizontal at basal half; mesepistenum not forming part of mesocoxal cavity; metacoxal plate with rounded tooth at free margin; tarsomeres 1–3 lamellate beneath.

Etymology. The epithet is a derivative of the Latin word par (=similar) + a tractosomus, a name of a genus of Dicrepidiina.

Distribution. Bolivia: Santa Cruz.

The formation of the mesocoxal cavity without mesepisternum separate Paratractosomu s gen. nov. from any other Dicrepidiina. Based on frontal shape, it is similar to Anoplischius and Crepidius , but in these two genera, the prothoracic groove is lacking and the free margin of the metacoxal plate is straight, without tooth or lobe. In addition, the borders of the mesosternal cavity are declivous in Anoplischius and vertical or declivous in Crepidius , and the male antenna is serrate in the former and flabellate in the latter.
