Cnemarachis duoflagella Smith & Molina, sp. nov.

Figs. 69–76.

Type series. Nine males and six females. Holotype male (CMNC), allotype female (CMNC), seven paratype males (four CMNC, two MFP, one UNSM), and five paratype females (four CMNC, two MFP) labeled “ CUBA: Pinar del Río / Sierra de la Guïra / 22.655, -83.444, 260 m / 17.v.2022; mv light / D. Alameda, D. Breto / CMN2022-091 ”. One paratype male (CMNC) labeled “ CUBA: Artemisa / Las Terrazas, Cañada del Infierno / 22.8427, -82.9876, 160 m / 15.v.2022; A.B.T. Smith / Y.S. Megna, D. Alameda / CMN2022-079; mv lights”.

Differential diagnosis. Dorsal surface shiny, without pruinosity, bicolored (Figs. 69–70); head, pronotum medially, elytra medially and along margin dark brown, pronotum laterally and elytral laterally (excluding margin) tan; clypeus distinctly sinuate (Fig. 72); frons with two distinct tubercles (Figs. 69–70); antennal club much shorter than funicle and scape; pronotum lateral margin smooth (Fig. 72); metasternum with only a few scattered setae medially; abdominal ventrites glabrous, with pruinosity along ventrite V; pygidium glabrous; male genitalia distinct as in Figs. 73–74.

The distinctive sutural stripe on the elytra is shared with the following species: C. aeneotincta, C. aeruginosa, C. alamedai, C. bruneri, C. guanahacabibensis, C. microsoma, C. rupestris, C. suturalis, C. terrazasensis, C. trinitariensis, and C. virgata. It can be distinguished from all of these species by the unique shape of the male parameres and endophallites (Figs. 73–74), the two tubercules on the frons, and the characters listed above.

Holotype description. See Figs. 69–74. Length 10.0 mm, width 4.5 mm. Dorsal surface shiny, without pruinosity; head, pronotum medially, elytra medially and along margin dark brown, pronotum laterally and elytral laterally (excluding margin) tan. Head: Surface densely punctate with deep, well-defined punctures; glabrous. Clypeus with apex reflexed, sinuate (bilobed) with middle slightly more than half the length of lobes; densely punctate. Frontoclypeal suture well defined, clypeus and frons on the same plane. Frons with two distinct tubercles, densely punctate. Antennae with 9 antennomeres; club approximately one-third length of funicle and scape; club, funicle, scape shiny. Pronotum: Surface moderately to densely punctate with well-defined punctures; glabrous. Apical angles weakly acute; lateral margins smooth, widest at medial point. Elytra: Surface densely punctate with well-defined punctures; glabrous except for a few widely scattered and obscure setae. Striae not defined, obscure. Legs: Protibia with three teeth, middle tooth slightly closer to apical tooth. Mesotibia and metatibia without medial carinae, mesotibia and metatibia with spines on lateral margin. Metatibial spurs unmodified, shorter spur approximately three-quarters the length of longer spur. Claws symmetrical with medial, triangular tooth slightly thicker and shorter than apical tooth. Venter: Prosternum with two small spines behind procoxae. Metasternum with only a few scattered setae medially, with weak pruinosity along lateral edge. Abdominal ventrites glabrous, with pruinosity along the lateral edges of ventrites I–IV and across most of ventrite V. Pygidium: Surface convex; moderately to densely punctate with well-defined punctures; glabrous; shiny, without pruinosity. Male genitalia: Parameres with ventral apex tapered, ending in bilobate bulb; dorsal top flat, with bidentate “hood” (Figs. 73–74). Endophallites with two elongate, lateral plates on either side of a ball of spines; base with two very long, thin, curved, whip-like spines that extend almost to the tip of the apex (Figs. 73–74).

Variation. Male length 10.0–12.0 mm, width 4.5–5.0 mm; female length 10.0–12.0 mm, width 4.0–5.0 mm. The dark stripe along the middle of the elytra can be approximately half the width of the elytra to thinner line only one-tenth the width of the elytra. Terminal abdominal ventrite longer and more inflated in females than in males. Female gonocoxites (Fig. 75) with basal lobes plate-like and inclined at a 45-degree angle medially and apical lobes thinner plate with two-pronged apex.

Etymology. Named for the two remarkable and diagnostic whip-like processes protruding forward from the base of the endophallites (Fig. 74). The name “ duoflagella ” is Latin for “two whips” and should be treated as a noun in apposition.
