Diagnosis.

Within the Bullatus Lineage: pronotum with three punctures in the dorsal row (Fig. 7D); lateral margins of pronotum only weakly convergent anteriad, sides nearly straight in anterior half (Fig. 7D); genital segment of both sexes dark, not contrasting with previous segments (Fig. 14D).

Description.

Measurements ♂ (n=5): HW/HL 1.62-1.71; PW/PL 1.44-1.60; EW/EL 1.21-1.29; ESut/PL 0.81-0.92; PW/HW 1.03-1.06; forebody length 3.8-4.2 mm.

Measurements ♀ (n=5): HW/HL 1.57-1.65; PW/PL 1.52-1.56; EW/EL 1.19-1.32; ESut/PL 0.85-0.92; PW/HW 1.03-1.06; forebody length 4.1-4.3 mm.

Similar to Bolitogyrus divisus and differing only in the following: pale areas of pronotum usually darker, orange-brown; tergite VIII always at least partially darkened apically or laterally; genital segment of both sexes dark, dark brown (Fig. 14D); lateral lobes of aedeagus with subapical tooth on dorsal face, tooth flattened, apex of lateral lobe flanged, not evenly cylindrical (Fig. 32B); some specimens with less-dilated paramere and with fields of peg setae less expanded basally and apically; paramere generally with sides of apical portion convergent and apex narrower.

Distribution.

Figure 31B. This species is only known to occur along the eastern portion of the Talamanca Cordillera in both Costa Rica and Panama.

Bionomics.

Bolitogyrus falini has been collected in March, May and June, and November, at elevations ranging from 1300-1660 m, from fungusy wood and using an FIT.

Etymology.

This species is dedicated to our colleague Zack Falin (SEMC), who collected many specimens of Bolitogyrus during extensive fieldwork in Central America.

Comments.

Bolitogyrus falini is sympatric with and similar to Bolitogyrus bullatus and Bolitogyrus pseudotortifolius but can be distinguished by the pronotum with three punctures in the dorsal row. Bolitogyrus falini and Bolitogyrus divisus appear to be sister species and are widely allopatric in Costa Rica. For details on their separation, see under Bolitogyrus divisus .
