However, to confirm species identity in most cases, it is essential to clear and examine the genitalia. Thus, features from both the male and female genitalia are included in each couplet where appropriate. 1. Dorsum of body green, usually with yellow median stripe; head yellowish, sometimes with red or reddish brown markings [Faded specimens are creamcolored to tan, and the median stripe may not be obvious.]; frons without pair of brown spots below toruli (Fig. 12); male: terminal segments of abdomen without sclerotized transverse bands or sclerotized invagination on midline of S8+9 (e.g., Fig. 16); female with stout, funnel-shaped spermatheca; bursal duct elongate, usually slender (e.g., Fig. 26 ) .......... collaris species-group (2) – Dorsum of body and head cream colored or tan, with brown markings; frons with pair of brown marks below toruli (Fig. 41); male: terminal segments of abdomen with sclerotized, transverse bands and sometimes sclerotized invagination on midline of S8+9 (e.g., Fig. 43 ); female with robust, tubular spermatheca; bursal duct fluted (e.g., Fig. 48 )......... flavescens species-group (5) 2.
