Enithares subparallela Lansbury, 1968

( Fig. 13 )

Enithares subparallela Lansbury, 1968: 408 ; NIESER & ZETTEL (1999: 132).

Material examined. PHILIPPINES: MINDANAO: Davao Province, Kidapawan, Mount Apo base camp, 200 m north of Lake Argo ; mountain forest creek, 1200 m a.s.l., 07°02′N 125°13′E, 13.iv.1995, leg. H. Freitag (33M), 2 JJ ( NHMW) .

Notes. This is a rarely collected backswimmer that was so far only reported from the type series (eleven specimens) from Mt. Kitanglad (alternative spelling: Mt. Katanglad) in Bukidnon Province, Central Mindanao, sampled at an elevation of 1480 m a.s.l. ( LANSBURY 1968). A field survey by the first author in the same mountain area at lower elevations (ca. 800–950 m a.s.l.) did not yield more specimens, but led to the discovery of another endemic species, E. gantsophora Nieser & Zettel, 1999 . The fourth author collected E. subparallela for the first time in Davao Province, in the Mt. Apo area at an elevation of ca. 1200 m a.s.l. A male is illustrated in Fig. 13 .

Distribution. Endemic in Mindanao, Philippines: Bukidnon (Mt. Kitanglad) ( LANSBURY 1968), first record from Davao (Mt. Apo).
