Diagnosis.

Within the Bullatus Lineage: two punctures in the dorsal row of the pronotum (Fig. 7C); dark abdominal segment VIII; humerus with pale marking distinctly narrower than half the distance between scutellum and humeral angle (Fig. 10C); median lobe in lateral view slender, not recurved dorsad, with subapical tooth (Fig. 19 H–I).

Description.

Measurements ♂ (n=5): HW/HL 1.68-1.78; PW/PL 1.59-1.71; EW/EL 1.16-1.28; ESut/PL 0.90-0.95; PW/HW 1.06-1.09; forebody length 3.5-3.7 mm.

Measurements ♀ (n=3): HW/HL 1.65-1.68; PW/PL 1.50-1.61; EW/EL 1.16-1.23; ESut/PL 0.95-0.96; PW/HW 1.00-1.03; forebody length 3.6-3.9 mm.

Extremely similar to Bolitogyrus tortifolius and differing only in the following: median lobe in lateral view slender, with subapical tooth and gradually narrowing to acute apex, which is produced ventrad, some specimens with weak flange on median lobe at midlength (Fig. 19 H–I); median lobe in parameral view similar to Bolitogyrus tortifolius but asymmetry less pronounced (Fig. 19G); paramere similar to Bolitogyrus tortifolius but more slender, less asymmetrical; peg setae similar to Bolitogyrus tortifolius but fields narrower and more similar to each other, about 6 peg setae wide at the widest part of each field (Fig. 19J); male sternite IX with apex shallower and narrower (Fig. 24B); female tergite X shield-shaped, apex narrower and more truncate than in Bolitogyrus tortifolius (Fig. 27B).

Distribution.

Figure 30C. Bolitogyrus pseudotortifolius occurs along the Central and Talamanca Cordilleras in Costa Rica and Panama, on the Caribbean side of the continental divide.

Bionomics.

Bolitogyrus pseudotortifolius has been collected in March-June, at 1050-1200 m (once at 1340 m), by fogging logs and using passive traps (FIT, Malaise). The specimen from Cartago, Costa Rica is not included in the distribution map as it was collected from cut logs that appeared to have originated from elsewhere (P.N. Thomas, pers. comm.). One relatively pale specimen may be teneral and was collected by processing forest litter in a Berlese funnel. This specimen may indicate the litter layer as a site for pupation or even a larval habitat.

Etymology.

The specific epithet refers to the similarity of Bolitogyrus pseudotortifolius with Bolitogyrus tortifolius .

Comments.

Among species of overlapping distribution, Bolitogyrus pseudotortifolius is most similar in habitus to Bolitogyrus falini and Bolitogyrus bullatus . It can be easily distinguished by the pronotum with two punctures in the dorsal row. The available specimen data on Bolitogyrus pseudotortifolius and Bolitogyrus tortifolius suggest that these two species are allopatric and that, the former may be broadly distributed along the Caribbean foothills of the continental divide in Costa Rica and Panama.
