description: <i>Pachyphymus carinatus</i> Dirsh, 1956 Figs. 1, 5A–D, 6 J–K, 8 A Dirsh 1956: 134–136 &gt;&gt; <i>Pachyphymus carinatus</i> Dirsh 1965: 258 &gt;&gt; <i>Pachyphymus carinatus</i> <b>Diagnostic redescription</b> (male, except where specified) General characteristics as for the genus, and as described in Dirsh (1956). Here, only diagnostic characters are described. The species can easily be distinguished by the degree of infumation on the hind wing (Figs. 6 J,K), shape of male supraanal plate (Fig. 1 G), shape of male cercus (Figs. 5 A–D), and shape of female subgenital plate (Figs. 1 H–J). <i>P. carinatus</i> is most similar to <i>P. samwaysi</i> <b>n. sp.</b> but can be distinguished on the basis of the position of the hind wing infumation at the apex of the wing in <i>P. carinatus</i> as opposed to closer to the center of the wing in <i>P. samwaysi</i> (compare Fig. 6 K vs. 6 L). The male cercus of <i>P. s a m w a y s i</i> forms a right angle when viewed laterally (Fig. 5 T vs. 5 D), and the pronotal crests in <i>P. samwaysi</i> are less elevated when viewed laterally than those of <i>P. carinatus</i> (Fig. 4 B vs. 1 D). <i>Wings.</i> Tegmen greatly surpassing end of abdomen (Fig. 8 A). Hind wing interior clear or with distinct bluish tinge. Distinct band of pale or dark infumation at apical edge of wing, reaching but not including extreme apex of hind wing (Figs. 6 J–K). <i>Abdomen.</i> Supraanal plate transverse, with a medial longitudinal concavity, lateral margins upcurved; posterior margin of supraanal plate with two lateral and one large median projection; central, basal pair of round tubercles and lateral pair of elongated tubercles (Fig. 1 G). Cercus, when viewed laterally, with apical projection which is short, robust, blunt or slightly pointed; basal surface of cercus with large posterior bulge (Figs. 5 A–D). <i>Phallic complex.</i> Epiphallus with short ancorae and broad, lobiform lophi with distinct apical projection (Fig. 1 M). <i>Female.</i> Subgenital plate trilobate, with posterior margin shallowly indented between lobes, median lobe rounded, broad and sometimes slightly or greatly notched (Figs. 1 H–J), even to the extent of appearing quadrilobate (e.g. Fig. 1 H). <i>Measurements.</i> (&amp;male; n= 29, &amp;female; n= 29) body: &amp;male; 17.0– 20.3, &amp;female; 21.7–26.8; pronotum: &amp;male; 3.0– 3.8, &amp;female; 3.2–4.7; tegmen: &amp;male; 12.7–16.7, &amp;female; 16.0– 21.3; hind femur: &amp;male; 7.3–9.5, &amp;female; 8.7–10.7 mm. <b>Material examined.</b> South Africa: Northern Cape: 25 mi W De Aar (- 30.6518, 24.0129) 4–5. xii. 1960 — 12 &amp;female;, 7 &amp;male; (SANC); 2 mi SE De Aar (- 30.6518, 24.0129) 5.xii. 1960 coll.

She was much larger (body: 26.8 cm) and had slight variation in the subgenital plate (Fig. 1 J) and shape of pronotal crests (Figs. 1 C–D; although this is not generally a good diagnostic character). One male and one female specimen collected from Tankwa Karoo National Park were also slightly distinct morphologically. The hind wing had a distinct bluish tinge (Fig. 6 J) and the male cercus was of slightly different shape than the norm for the species (Figs. 5 C–D).
