Onycholabis luzonensis Jedlička, 1935:31 ( Philippines) .

Specimens Examined. Holotype, a male ( NHM), ‘‘ Typus’ ’/‘‘ Mt. Makling , Luzon, Baker’ ’/ ‘‘ Onycholabis luzoensis sp. n., type, det. ING. JEDLICKA’’.

Description. Jedlička’s description of this species is also brief. We add the following: microsculpture on head formed of distinct isodiametric meshes; antennomeres IV–XI pubescent; PW: HW ¼ 1.31; PW: PL ¼ 1.27; PW: PAW ¼ 1.75; PW: PBW ¼ 1.40; EW: PW ¼ 1.48; EL: EW ¼ 1.58; relative lengths of scape and antennomeres II–VI as follows: 1.00: 0.56: 1.19: 1.31: 1.19: 1.13; mentum with tooth simple; submentum with 1 pair of long setae and 1 pair of short setae laterally; basal fovea of pronotum long and deep, sparsely punctate; elytra with basal setiferous pore puncture present; elytral apex slightly truncate near suture; tibia longitudinally sulcate; tarsomeres longitudinally sulcate both medially and laterally on dorsum, tarsomere IV not bilobed, tarsomere V without seta on ventral side; sixth visible sternum with 2 marginal setae in male.

Remarks. When Jedlička (1953:108) described genus Sternodelus for O. arrowi , he correctly recognized that species as different from Onycholabis in having antennomere III glabrous. Curiously, he did not mention his other species, O. luzonensis Jedlička , adults of which also have antennomere III glabrous.
