Fig. 17
Diagnosis. This species is very similar to Ochrotrichia flagellata which was described from Panama by Flint in 1972. The new species differs from O. flagellate most notably in the structure of the phallus apex; in O. flagellata the phallus ends in a spiral process which is absent in O. birdae. There are several other differences seen in the new species; the dorsal extension of segment VIII is more pronounced and the apical portion of segment X is straight as opposed to upturned, both features as seen in lateral view. Also, in O. flagellata the inferior appendages are shorter than the tenth segment
Male. Length 2.4-2.6 mm, 27 antennal segments, brown in alcohol. Abdominal segment VII annular, without short posteroventral process. Segment VIII in lateral view with lobe-like dorsal extension; ventrally square; dorsally deeply incised forming elongate lateral lobes posteriorly, anteriorly rounded. Segment IX reduced dorsally to narrow band. Segment X in lateral view tapering distally to narrow, acute apex; dorsally wide basally gradually tapering distally to rounded apex. Inferior appendages rectanguloid in lateral view, abruptly widening apically, numerous peglike setae on inner posterior margin and subbasally, extending distally beyond segment X; in ventral view wide basally curving on inner margin to rounded apex, numerous peglike setae on apical mesal margins. Phallus elongate, wide basally, narrowing at midlength, apical portion about same length as basal, very thin and narrowing distally.
Female. Unknown.
Type material. Holotype, male— Panama, Bocas del Toro Province, Quebrada Rambala, near Rambala Jungle Lodge, 3.74 km SSE Rambala, 8.91627°N and 82.15469°W, 120 m, Malaise trap, December 21–31, 2016, E. Carlson. Paratype. ibid., November 15–20, 2016, 1 male (SCH).
Etymology. Named for Suzanne Bird Boyden, colleague of the first author at Clarion University, in recognition of her contributions to ecology, and instilling an appreciation of nature in our students.
Note. As the new species is similar to O. flagellata, which we have also collected collected in Bocas del Toro Province, Panama, we have provided new drawings (Fig. 18) of the species from these Panamanian specimens. Material examined: Bocas del Toro Province, Quebrada Rambala, near Rambala Jungle Lodge, 3.74 km SSE Rambala, 8.91627°N and 82.15469°W, Malaise trap, March 31–April 11, 2015, E. Carlson, 4 males; ibid., November 15–20, 2016, 1 male; ibid., February 6–12, 2017, 2 males, tributary of Quebrada Rambala, Rambala Jungle Lodge, 134 m, November 29, 2014, E. Carlson, 1 male.
