Duwal, Ram Keshari & Lee, Seunghwan, 2011, A new genus, three new species, and new records of plant bugs from Korea (Hemiptera: Heteroptera: Miridae: Phylinae: Phylini), Zootaxa 3049, pp. 47-58 : 54-55

Genus Orthophylus gen. nov.

Type species: Orthophylus yongmuni sp. nov.

Diagnosis. Generally recognized by elongated, parallel sided, uniformly pale body; pale yellowish brown dorsum furnished with uniformly distributed silvery setae and simple dark setae; elongated, long antenna (reminiscent of some orthotyline species); slender and yellow legs; Z-shaped curved endosoma, with two unequal processes supported by membranes, secondary gonopore located between two processes ( Fig. 5A), and distinct parameres ( Figs. 5B–C).

Description. Male. Body elongated, parallel sided. COLORATION ( Fig. 1): Entire body and appendages brightly colored. SURFACE AND VESTITURE: Head distributed with pale brown, erect and white semierect shining setae; dorsum furnished with uniformly distributed simple dark sub-erect setae and pale setae; ventrally covered with shining pale pubescences. STRUCTURE: Head small, narrow and triangular; antennae slender and long (as in Orthotylinae ). GENITALIA ( Figs. 5A–D): Endosoma Z-shaped, with two unequal processes, short process reaching or slightly surpassing bending point of elongated process; secondary gonopore lies between processes ( Fig. 5A), a tube like structure developed at base of gonopore. Phallotheca slender and attenuated towards apex ( Fig. 5D). Left paramere with a short posterior process, anterior process thick and broad ( Fig. 5B). Right paramere, narrow at base, middle region gradually wider and subapically triangular with a finger-like protuberance apically ( Fig. 5C).

Distribution. Korea (South).

Etymology. After the subfamily Orthotylinae and the generic name of phyline bug, Phylus Hahn , referring to the overall similarity.

Discussion. The new genus is morphologically very similar to Orthotylinae as well as phyline genus, Phylus Hahn , from which it is distinguished by the simple, sclerotized, Z-shaped endosoma with two unequal apical processes which are supported by membranes.
