Taxonomic notes on Cryptamorpha sculptifrons Reitter (Coleoptera, Silvanidae), with description of its larval morphology.

Yoshida T, Hirowatari T - Zookeys (2014)

Bottom Line: The mature larva of C. sculptifrons is described.It is hypothesized that a variety described by Grouvelle (1908), C. sculptifrons var. punctifrons from India, might not be conspecific with Japanese C. sculptifrons.It is also suggested that larvae of Cryptamorpha can be distinguished from larvae of the tribe Brontini by the relatively thick antennae and the 3rd antennomere which is less than 3/4 of the length of the 2nd.

ABSTRACT
Cryptamorpha sculptifrons Reitter, 1889 is redescribed and a lectotype and paralectotype are designated. The mature larva of C. sculptifrons is described. It is hypothesized that a variety described by Grouvelle (1908), C. sculptifrons var. punctifrons from India, might not be conspecific with Japanese C. sculptifrons. It is also suggested that larvae of Cryptamorpha can be distinguished from larvae of the tribe Brontini by the relatively thick antennae and the 3rd antennomere which is less than 3/4 of the length of the 2nd.

A Habitus, dorsal view B head, dorsal view; C right antenna, dorsal view D right mandible, ventral view E left mandible, ventral view F right maxilla, dorsal view G labium, ventral view H 8th to 10th abdominal segments, dorsal view I right foreleg, dorsal view. Abbreviations: cl–claw; fa–frontal arm; fe–femur; ma–mala; mo–mola; mp–maxillary palpus; pr–prostheca; sp–stipe; st–stemmata; ti–tibiotarsus; tr–trochanter; ur–urogomphus; 1a–1st antennomere; 2a–2nd antennomere; 3a–3rd antennomere; 8as–8th abdominal segment; 10as–10th abdominal segment. Scale: a for A–H, 2.0 mm for A, 1.0 mm for B, H, 0.5 mm for C–F and 0.3 mm for G; b for I, 0.5 mm.
