Description
Cnemarachis galindensis Smith & Molina, sp. nov.
Figs. 109–115.
Type series. Two males. Holotype male (CMNC) and one paratype male (MFP) labeled “ CUBA: Mayabeque / Lomas de Galindo / 13.v.2018 / C. Loiz, A. Font, J.L. Leal ”.
Differential diagnosis. Dorsal surface glabrous, shiny, without pruinosity (Figs. 109–110); head and pronotum brown, elytra reddish brown; clypeus sinuate (Fig. 112); frons weakly concave, without two distinct tubercles; antennal club approximately equal to funicle in length; pronotum lateral margin crenulate (Fig. 112); pronotum surface with three shallow concavities (two laterally behind apex and one basomedially); metasternum densely setose; abdominal ventrites lightly setose, with pruinosity and longer setae on ventrite V; pygidium setose; male genitalia distinct as in Figs. 113–114.
The distinctly crenulate pronotal lateral margins and larger size characteristics are shared with the following species: C. acunai, C. crenaticollis, C. expansa, C. fimbriata, C. granmensis sp. nov., C. independentista, C. onchophora, C. paulseni sp. nov., C. sarlacca, C. yunquensis sp. nov .. It can be distinguished from all of these species by the unique shape of the male parameres and endophallites (Figs. 113–114) (specifically, the blunt, lobed endophallite process), and the characters listed in the diagnosis.
Holotype description. Figs. 109–114. Length 16.5 mm, width 10.0 mm. Dorsal surface glabrous, shiny, without pruinosity; head and pronotum brown, elytra reddish brown. Head: Surface densely punctate with deep, well-defined punctures; glabrous. Clypeus with apex reflexed, sinuate (bilobed) with middle slightly shorter than the length of lobes; densely punctate. Frontoclypeal suture well defined, clypeus and frons on the same plane. Frons weakly but evenly convex, densely punctate. Antennae with 9 antennomeres; club approximately equal to funicle in length; club, funicle, scape shiny. Pronotum: Surface with three shallow concavities (two laterally behind apex and one basomedially); densely punctate with well-defined punctures; glabrous. Apical angles weakly acute; lateral margins crenulate, widest at medial point. Elytra: Surface densely punctate with well-defined punctures; glabrous. Striae not defined, obscure. Legs: Protibia with three teeth, middle tooth distinctly closer to apical tooth. Mesotibia and metatibia without medial carinae, mesotibia and metatibia with spines on lateral margin. Metatibial spurs unmodified, shorter spur approximately two-thirds the length of longer spur (holotype has one metatarsomere 3–5 missing). Claws symmetrical with medial, triangular tooth shorter than apical tooth. Venter: Prosternum without two small spines behind procoxae (but they may be reduced and obscured by setae). Metasternum setose, without pruinosity. Abdominal ventrites lightly setose, with pruinosity and longer setae on ventrite V. Pygidium: Surface convex; moderately punctate; lightly setose; shiny, without pruinosity. Male genitalia: Parameres with ventral apex truncate with a blunt, downward facing spine; dorsal base evenly rounded with a distinct notch and a dorsomedial ridge (Figs. 113–114). Endophallites with a thick, lobed process with a blunt, upward directed spine; base without distinct processes (Figs. 113–114).
Variation. Unknown.
Etymology. Named for Lomas de Galindo, where the two known specimens were collected.
Distribution. See Fig. 115. CUBA (2): Mayabeque (2): Lomas de Galindo.
Temporal data. May (2).
