Fuller, E. & Platia, G., 2006, A revision of the click beetle genus Ctenoplus Candèze, 1863 (Coleoptera: Elateridae, Synaptina), Zootaxa 1217 (1), pp. 1-76 : 42-43

Ctenoplus pseudocollaris n. sp.

Figures 12 , 72 , 109

Diagnosis

Small, red and black Ctenoplus with small, sparse frontal punctures. This species is very similar to C. collaris Candèze. In C. pseudocollaris , the apex of the median lobe is produced to a point ( Fig. 72 ), whereas in C. collaris , the apex of the median lobe is more rounded ( Fig. 71 ). Also, the lateral margins of the median lobe in C. pseudocollaris are evenly tapered to the apex, whereas they are sinuate in C. collaris . Externally, the only distinguishing character found is in the punctures of the frontoclypeus. In C. pseudocollaris , the frontal punctures are smaller and sparser ( Fig. 12 ), whereas in C. collaris , the frontal punctures are larger and more dense ( Fig. 11 ). The venter of the meso­ and metathorax is reddish in C. pseudocollaris . In C. collaris , the venter of the meso­ and metathorax is reddish in females but black in males. The female of C. pseudocollaris is unknown.

Description

Externally as in C. collaris except as noted above.

Length: 6.5–7.0 mm, width: 1.5 mm

Male Genitalia as in Fig. 72 ; articulation between basal piece and parameres heavily sclerotized and conspicuous; parameres not enclosing median lobe ventrally except at base.

Material examined and range

3♂. [ MALAYSIA] Holotype male, paratype male. “MALAYA. Pahang, Kuala Tahan , 200m, Dec. 14, 1958 "; “ T. C. Maa, Collector, BISHOP”; “ Ctenoplus collaris Candeze, 1889 , H. OHIRA Det. 1978" [ BPBM]; paratype male, “ Malacca, Tenga Gebirge, P. Zobris. V.” [ CPG]. This species has been found only in Malaysia ( Fig. 109 ).

Etymology

The species epithet is derived from ‘pseudo­’ + ‘collaris’, denoting its similarity to C. collaris .

Natural history C. pseudocollaris has been collected at 200 m in mid­December.
