Discussion. Enithares producta was originally described from a pair of male specimens taken in the Minahasa region of far northeastern Celebes, with two female paratypes from the vicinity of Palu in north-central Celebes (Lansbury 1968). Additional records from northern Celebes were provided by Nieser & Chen (1996), who indicated doubt as to whether the two paratype females from the Palu area were actually conspecific. An examination of multiple additional series taken by the author in the Palu area has now allowed a comparison of their male genitalia with those of the Minahasa populations. The genitalic structures are nearly identical (compare Figs. 68, 69), thereby validating Lansbury’s original interpretation, and mitigating the doubts raised by Nieser & Chen. Based on these findings, it may be assumed that E. producta occurs throughout the entire extensive length of the northern peninsula of Celebes.
