Skelley, Paul, Xu, Guang, Tang, William, Lindström, Anders J., Marler, Thomas, Khuraijam, Jibankumar Singh, Singh, Rita & Rich, Stephen, 2017, Review of Cycadophila Xu, Tang & Skelley (Coleoptera: Erotylidae: Pharaxonothinae) inhabiting Cycas (Cycadaceae) in Asia, with descriptions of a new subgenus and thirteen new species, Zootaxa 4267 (1), pp. 1-63 : 21

Fupingensis species group

Adult diagnosis. The C. ( Cycadophila ) fupingensis species group is distinguished from other members of Cycadophila by the reddish-brown body with dark mark along elytral suture; head dorsal surface flattened in profile; supraocular stria present, short, extending basal 1/3 length of eye; maxillary palpi normal in length, not more than 2× longer than labial palpi; ventral interocular distance approximately 1/3 head width; submental-gular suture primarily flattened, medially with weak, darkened transverse depression with row of setose punctures; pronotal anterior angles rounded, surface near anterior angle convex; lateral carinae evenly arched most of length, basal margin appearing evenly sinuate; pronotal lateral carina thin in lateral view, with single row of setose punctation on marginal surface; prosternal process narrow (<1/2 width of profemur), truncated at apex, apex depressed, in lateral view convex; protibia weakly dilated distally, lacking fringe of stout setae along apical and lateral margins; coxal line behind mesocoxae without punctures; male genitalia with tegmen moderately twisted basally, penile strut 5.0 0× length of median lobe; and sexual dimorphism present with males having strongly dilated pro- and mesotibiae.

Remarks. Cycadophila fupingensis , currently the only member in the group, has morphological similarities with other groups in the subgenus. For example, the flattened head and general body shape are most similar to the lata group, the short ocular stria is most similar to the nigra group, and the narrowed tibia lacking stout setae with no notable dimorphism in on the legs and the male genitalia are most similar to the papua group. Molecular data analyzed in this paper place this group closest to the lata species group ( Fig. 1 ).
