Microlaqueus gen.nov.

Type-species: Microlaqueus isolatus sp.nov., the only included species.

Etymology. micro- small, laqueus (m) snare, referring to the oval apical cells of the tegmen.

Distribution. Jamaica.

Diagnosis. Antenna with small postpedicel bearing 7 coeloconic sensillum pits of 2 distinct sizes with prominent double rims ( Fig. 24 E) around the base of a short, broad basiconic sensillum ( Fig. 24 D). Eye longer than lateral margins of pronotum. Tegmina each with venation irregular, not contrastingly pale, costal margin with 3–4 perpendicular crossveins, outer anteapical cell very slender, tegminal tip with small, round preapical cell edged with 4–5 still smaller apical cells, inner 2 apical cells distinctly larger ( Fig. 3 A).

Remarks. The numerous small cells around the pointed tegminal tips are unique, and the large coeloconic sensilla tightly grouped around the basiconic sensillum are distinctive within the Microsarganini, resembling the sensilla of some old-world Cercopinae ( Liang & Fletcher 2002).

Only one species is known.
