Type material.

Holotype male: "PANAMA: Colón Pr., San Lorenzo Forest. 9°17'N, 79°58'W. Flight Intercept FIT-B2-16. 21-24 May 2004 A. Tishechkin. AT- 490 " / "LSAM 0111233" (FMNH). Paratypes (3): locality, collector and methods as for holotype, collected 13-14.v, 18-19.v, and 20-21.v, all 2004 (GBFM, AKTC).

Diagnostic description.

This species is very similar to Operclipygus sulcistrius as described above. It differs in the following characters: length: 2.25-2.31 mm, width: 1.47-1.56 mm; body smaller, rufo-brunneus; supraorbital stria absent; anterior submarginal stria recurved for a shorter distance along pronotal disk, about one-eighth total length; elytral striae less strongly impressed, the 5th and sutural striae not joined by a basal arch; inner subhumeral stria vaguely traceable by a series of punctures in apical half; propygidial punctures smaller and sparser, only slightly elongate, separated by their widths or more; pygidium with numerous larger punctures evenly scattered among the fine, conspicuous ground punctation. Male genitalia indistinguishable from those of Operclipygus sulcistrius (Fig. 3).

Remarks.

Among members of the Operclipygus sulcistrius group, Operclipygus schmidti is distinct in having the 5th and sutural elytral striae complete but not united by a basal arch. It is also unusual in lacking a supraorbital stria.

Etymology.

We name this species in honor of Johannes Schmidt, the great 19th century German histerid specialist, describer of numerous species of Neotropical Exosternini .
