( Figs. 7–8 , 15 , 17–18 , 23 )

Diagnosis. Length 6.7–8.7 mm. Integument ( Figs. 7–8 ) black, no broad scales present, surface deeply, densely punctate throughout. Antennal scape ( Fig. 15 ) short and stout, club with basal shiny, glabrous portion comprising about 0.6 length of club. Front femora with inner margin simple, occluding area on front tibiae simple, not modified; middle and hind femora and tibiae with inner margins simple. Front tibia with inner margin smooth, not serrate. Hind tibia straight along outer margin. Tarsi with ventral pilose pads limited to narrow band across apex of tarsite 3. Tibiae with subapical tooth large, similar in size and form to apical tooth. Aedeagus as in figs. 17–18.

Material examined. Holotype: Mexico. Hidalgo, Zacualtipan, Hoge ( BMNH). Other specimens: Oaxaca, 17 km N Haujuapan de Leon, 17º41.60' N 97º45.81'W, 29.vi.1996, H. Brailovsky & E. Barrera (1, CMNC; 1, CWOB).

Distribution. Mexico (Hidalgo and Oaxaca) ( Fig. 23 ).

Biology. Unknown.

Comments. This species was erroneously placed as a synonym of the introduced Polytus mellerborgii (Boheman) in O’Brien & Wibmer (1982: 221). It is quite clearly a species of Eucalandra and here transferred to this genus.
