19) with tergite I smooth with some setiferous punctures, with lateromedian longitudinal carinae very weak, in dorsal view present on anterior 0.2; tergite I in lateral view, with spiracle positioned anterior to centre, about 0.3 of way along; base with rather truncated lateral tooth, margin pointing laterally (Fig.
Pygidium flattened on basal half, shallowly depressed on distal half, with scattered setiferous small punctures; marginal bead widened near apex, with 14 short setae.
Mesoscutum convex, sparsely punctate, without any impressions (Figure 14), scutellum smooth with sparse punctures; mesopleuron smooth with few very fine setiferous punctures dorsally, epicnemial carina complete, curved to meet anterior margin of pleuron just below subalar prominence (Figure 15); metapleuron smooth with a few rugae above and parallel to juxtacoxal carina (Figure 15).

As defined in Sharkey & Wharton (1997), setiferous and setose both refer to areas bearing setae, setiferous areas "not necessarily with dense setae" and setose areas "with dense setae." Data on mandibular sculpture, setation, and tooth shape were taken as described in Kula & Zolnerowich (2008).
(C.) cuschensis because (1) membranous distal part of the caudal knob in apterous viviparous females is small, contrasting very little with the rest of the knob; (2) the dorsum of head, antennae, legs, and siphunculi are very weakly pigmented in apterous viviparous females; (3) setiferous sclerites are absent from dorsum of abdomen in apterous viviparous females; and (4) they are green when alive.
Marginal papillae and setiferous sclerites absent; intersegmental and stigmatic sclerites unpigmented.
Visible abdominal sternites 2[degrees] to 4[degrees] slightly depressed at middle; 5th sternite widely convex, shiny, with scattered setiferous punctures; anal plate long, weakly concave, with a central, moderate prominence covered by setigerous granules (Fig.
