Cylindera (Cylinderina) genieri Cassola & Werner, 2003

Material examined. PHILIPPINES, Apayao Province, Municipality of Calanasan, 1♂, 1♀, Brgy. Tanglagan [18.3674°N, 120.9571°E], IX.2018, coll. R.J. T. Villanueva ( Fig. 3B); UMCRC 010132, UMCRC 010133.

Identification. This species is very similar to C. werneri Wiesner, 1988 and C. vanderberghei Dheurle, 2016 , in having the head shiny, bluish-violet above and metallic green to bluish-green on the clypeus, frons, antennal plates, and genae (Cassola and Werner 2003). However, brown pigmentation is present at the tip of each elytron in C. genieri but absent in both C. werneri and C. vanderberghei . The aedeagus of C. genieri and C. werneri have the inner sac with a long, narrow flagellum whose upper convolution is crossed by a V-shaped sclerite (Cassola and Werner 2003), but the aedeagus of C. genieri is fusiform, with a straight, blunt apex compared to the slightly tapering apex of C. werneri .

Remarks. This species was found on a steep slope along a forest trail. It was perching atop a fallen dried leaf on the ground. Unlike other species of tiger beetle encountered during this study, which climb into the insect net, when a net is positioned above an individual of this species, it tends to drop to the ground and crawl under a leaf or sometimes into a small crevice in the ground.
