Tepa rugulosa (Say)

Pentatoma rugulosa Say, 1832:319 . Thyanta rugulosa: Uhler, 1872:399 . Thyanta punctiventris Van Duzee, 1904:53 , 55 - 56. NEW SYNONYMY. Tepa rugulosa : Rolston and McDonald, 1984:77,80,fig. 42.

The type specimen of Pentatoma rugulosa is no longer in existence; however, the original description is adequate to fix the species. Say (1832) stated that P. rugulosa has the " thorax much contracted before; lateral edge rather concave than rectilinear: tergum black at base, the three ultimate segments and the margin green. " Tepa rugulosa is the only species in the genus with both the anterolateral margin of the pronotum distinctly concave and the tergum black as in the above description.

Van Duzee (1904) stated that his new species Thyanta punctiventris may only be a color variety of T. rugulosa . Several species of Tepa and the closely related genus Thyanta are now known to have several color forms. The different color forms are determined by environmental factors and have no geographical significance (Mc Pherson, 1977, 1978; Ruckes, 1957). The type specimens of Thyanta punctiventris have been examined, and structurally they are typical specimens of Tepa rugulosa .

Once again, Van Duzee did not officially designate a holotype or paratypes in his original description of Thyanta punctiventris . Only 6 of the original 12 syntype specimens were located. The male specimen labeled " Willist'n N. D. Jun. 8 - 9 Wick ham / HOLOTYPE punctiventris " is here designated as the lectotype. The remaining 5 specimens are designated as paralectotypes. They have the following locality data: " Willist'n N. D. Jun. 8 - 9 Wickham / PARATYPE punctiventris " (9); "Colo 1163 / Det. Uhler / PARATYPE punctiventris " (9); " Salt Lake, 14 - 6 - 98, Ut / Heidemann Collector / PARATYPE punctiventris / E P Van Duzee Collection " (9); " Gnd Junc Col . 7 - 28 - 00 / E P Van Duzee Collector / PARATYPE punctiventris / E P Van Duzee Collection / Thyanta punctiventris Van D., Det. V. D. " (9); and " Gnd Junc Col. 7 27 - 00 / E P Van Duzee Collector / PARATYPE punctiventris / E P Van Duzee Col lection " (? - abdomen missing).

Specimens of T. rugulosa have been examined from British Columbia, Canada, and from the following states: Arizona, California, Colorado, Idaho, Montana, Ne braska, Nevada, New Mexico, North Dakota, Oregon, South Dakota, Utah, Wash ington, and Wyoming.
