Diagnosis.

This species is placed in the Alisotrichia orophila group of Oláh and Flint (2012) on the basis of the dorsolateral process from segment VIII which bears an elongate seta, with closest similarity to A. neblina Harris & Flint and A. coclensis Armitage & Harris. Like these species, A. eisbergae sp. nov. has posterior processes and spines from the margin of segment VIII, but the new species is distinguished by the shape of these spines and by the phallic structure.

Description.

Male. Total length 1.6-1.8 mm, 17 antennal segments, scape enlarged, pedicel twice as long as proximal flagellomeres, maxillary palp with five segments, brown in alcohol with no obvious patterns on wings. G enitalia. Abdominal segment VII annular without ventromesal process. Segment VIII incomplete dorsally, setal-bearing process dorsally, pair of elongate processes posteriorly; in dorsal view, elongate seta emanating from apex of elongate, narrow, lateral lobes, posterior spines from mesal margins; in ventral view emarginated posteriorly with mesal spines. Segment IX elongate, anteriorly narrowing to short apodeme; in dorsal view narrowing to rounded distal margin; in ventral view narrow, mesal narrow process with crenulate outer margins. Segment X apparently fused with IX and indistinct laterally. Phallus tubular, narrowing at midlength, posteriorly with pair of lateral thin, lateral bands adjacent to and extending beyond the ejaculatory duct; in lateral view wide basally and distally, narrow, spinelike band mesally.

Distribution.

Panama.

Etymology.

This species is named for Ms. Deborah Eisberg of Boquete, Panama in recognition and thanks for her support of our research program. The species name is a female noun in the genitive case.

Remarks.

The pair of elongate processes on segment VIII differed slightly in the specimen from the Río Cacaito (Panama Oeste Province) compared to the other specimens examined.
