(<i>N</i>.) <i>flavescens</i> <i>, escomeli</i> and <i>figuralis</i>) in which the adults have robust, waxy bodies; like <i>C</i>. (<i>N</i>.) <i>escomeli</i> and <i>C</i>. (<i>N</i>.) <i>flavescens</i>, they are largely brownish with dark brown marks. <i>C</i>. (<i>N</i>.) <i>porterinus</i> can often be separated from the other two species by its heavy prothoracic markings, lack of stripes on the scapes, and a flagellum that is dark brown to black basally and becomes lighter distally (Figs 40f, 41f). The male genitalia, with its dome-like, almost spherical gonarcus, are particularly useful in distinguishing the species (Figs 67, 68). However, only a few, subtle differences distinguish the <i>C</i>. (<i>N</i>.) <i>porterinus</i> female genitalia from those of the other two species. In <i>C</i>. (<i>N</i>.) <i>porterinus</i>, the distal surface of the sclerotized process of the subgenitale is flat and roughly heart-shaped (with a lobe in each dorsal corner, tapering to a ventral apex) (Fig. 71). The neck at the base of the process is short (considerably shorter than the length of the terminal surface of the process), and it ends in an sharply angled connection to the distal process (Fig. 48c). Also, the membranous area ventral to the subgenitale is dense and folded, not clear and smooth, as in <i>C</i>. (<i>N</i>.) <i>flavescens</i>. <b>Description.</b> <i>Head</i> (Figs 40f, 41f): Width (frontal, including eyes) 1.7–1.8 mm; ratio, head: eye width = 2.6–2.8:1; distance (straight-line) between tentorial pits 0.44–0.53 mm. Distance between antennae ̴ 0.11–0.12 mm; length of frons (midantenna – midway between tentorial pits) ̴ 0.44–0.57 mm; clypeus ̴ 0.32–0.34 mm long. Antenna 0.7× length of forewing (10.8–11.0 mm). Vertex slightly raised, flat anteriorly, with very small, smooth, rounded posterior fold; surface of vertex smooth, without setae. Frons smooth, rounded laterally, shiny throughout. Clypeus mostly flat, rounded laterally, center without raised fold; surface smooth. Labrum flat; distal margin straight; dorsal surface smooth. <i>Head coloration</i>: Head cream to tan; vertex with brown markings around edges of central raised area; brown stripe around mesal edge of dorsal torulus; torulus with another elongate brown stripe mesally; frontal torulus tan, with diffuse brown stripe below antennal base; frons tan to amber, lateral margins marked with reddish brown, with pair of crescent-shaped, dark brown marks below frontolateral margin of torulus; clypeus light brown. Genae cream, with brown longitudinal stripe. Scape tan, with brown at base; pedicel light brown; flagellum dark brown basally, becoming lighter brown, then tan distally, with dark brown setae basally, becoming amber distally. Maxillary palp with distal three segments mostly brown; basal two segments amber. Two distal segments of labial palp brown, basal segment amber. Venter mostly tan; area posterior to eyes with brown marks; stipes, galea with some brown markings. <i>Thorax</i> (Fig. 40f): Pronotum wider than long: ̴0.8–1.0 mm long; ̴ 1.2–1.4 mm wide; cream to tan, with brown, crooked mesal stripe, pair of brown, crooked sublateral stripes (̴ 0.2 mm wide), lateral margin brown anteriorly, sometimes entirely; numerous long, mostly black setae (longest ̴ 0.20–0.25 mm long). Meso-, metanota cream to tan, with brown, sublateral markings; sparce brown setae on mesonotum, sparce amber setae on metanotum. Pleuron mostly brown. Legs cream, without markings; tarsi amber. Tarsal claws dark amber, curved without deep cleft or quadrate base, with few long amber setae. <i>Wings</i> (Fig. 66): Forewing 15.1–16.7 mm long, 4.9–5.3 mm wide; L:W ratio, 3.0–3.3; width greatest near midpoint, ratio maintained through distal 3/4th of wing, tapering at basal 1/4th; costal margin fairly straight, sloping gradually at base; apex ovate. Cu crassate at furcation of Cu1 and Cu2. Costal area slightly enlarged; height of tallest costal cell (#5, 6) = 4.3–5.3× length of first costal vein, 0.19× width of wing. Subcosta, radius almost straight; most subcostal veinlets, radial crossveins straight. Twelve to thirteen closed radial cells (between R and Rs), height of tallest radial cell 1.2–1.5× width; other than radial crossveins, only gradate veins in contact with PsM. Four b cells, four b’ cells. First intramedian cell ovate, 0.6–0.7× width of third medial cell; inner row of four to five gradate veins; seven to eight outer gradate veins; both rows regularly stepped, parallel to each other distally. Second cell beneath Rs with i.g. at base = 1.7–2.0 mm tall, 2.7–3.2× width; third cell = 1.8–2.0 mm tall, 2.8–3.3× width. Second gradate cell 1.2–1.7 mm tall, 1.8–2.9× width; third gradate cell 1.1–1.6 mm tall, 1.8–3.0× width. Length of second cell beneath Rs with i.g. at base = 1.4–1.6× length of second gradate cell. Three intracubital cells; distal one open, icu1, icu2 each shorter than icu3; icu1 similar in length or 0.8× shorter that icu2. Vein 1A forked. Hindwing narrow, with tip ovate; 12.7–14.7 mm long, 4.3–4.8 mm wide.
