Figs. 2 View Fig , 4, 7, 9, 11 View Figs

Diagnosis. Similar in dorsal color pattern to Carinisphindus leptosphinctos , but scutellum darker than elytral base and ventral punctation smaller and less defined. The metepisternum bears 9–11 small, adjacent punctures in a row, while C. leptosphinctos has 5–6 larger punctures separated by a distance approximately equal to one puncture diameter.

Description. Length 1.5–1.9mm (x 5 1.7 mm). Color of head and pronotum piceous; elytra with yellow band on basal quarter, piceous on apical threequarters ( Fig. 2 View Fig ), basal band slightly narrowed medially by gradual anterior extension of piceous coloration; prosternum, mesosternum, and metasternum red­brown; eyes black. Body very shiny. Exposed surfaces with dense minutely reticulate microsculpturing. Setation short, sparse, golden, suberect. Head ( Fig. 4 View Figs ) with dorsolateral punctures elongate and fused, forming 7–9 strong longitudinal grooves beginning between antennal insertion and clypeus, extending posteriad beyond midpoint of eyes, terminating before posterior margin of head. Eyes coarsely faceted. Mandibles large, with one large apical tooth and one well formed small subapical tooth. Labrum rectangular, dorsal surface rugulose, anterior border strongly margined; clypeus large, emarginate apically and laterally, shinier than frons, lacking reticulate microsculpturing, bearing setiferous punctures; frontoclypeal suture arcuate. Antennomere III about 33 long as broad, IV 1.53 length of V, gradually swollen distally, V–VII submoniliform, VIII disk­shaped, X 23 length of IX, IX–X forming densely pubescent oval compact club ( Fig. 4 View Figs ). Pronotum ( Fig. 7 View Figs ) with anterolateral angles square, margined laterally and posteriorly, with a pair of posterior depressions just lateral to carina, irregular shallow punctures medially, punctures with well defined round edge; median longitudinal carina weakly defined, projecting upward as small denticle opposite scutellum. Prosternum with large, dense punctation, punctures about 1 ⁄ 5 width of prosternal process between coxae; prosternal and mesosternal process weakly emarginate. Mesosternum ( Fig. 9 View Figs ) short, reflexed, with dense punctures in medial half; mesepisternum with one large oval puncture ⅔ width mesepisternum. Metasternum ( Fig. 9 View Figs ) inflated, with irregular shallow punctures anterolaterally becoming sparser and then absent medially and posteriorly, with dense row of conjoined punctures in transverse groove opposite each metathoracic coxa and anterior row of four large punctures opposite mesothoracic coxa; anterior edge with broad margin opposite mesothoracic coxa, metasternal suture complete, extending to anterior margin, intercoxal notch keyhole­shaped, with narrowly rounded anterior region, strongly constricted mid­region and with sides diverging posteriorly; metepisternum with continuous longitudinal row of 9–11 poorly defined punctures. Scutellum small, oval­chordate, with median longitudinal carina. Elytron with strial interspaces moderately convex anteriorly, flattened posteriorly; with trace of subhumeral depression; humeral calli weakly produced; inner edge of elytron reflexed anteriorly (forming the elytral carina); epipleuron very narrow, extending to posterior margin of sternite III. Abdominal sterna imbricate, not lying flat in one plane, ventrite I with shallow irregular punctures; intercoxal process with acute apex and median longitudinal carina; ventrites II–IV with transverse row of depressions basally (often hidden by overlapping anterior sternite) and sparse setiferous punctules distally.

Male. Metafemoral tooth small, with broad base and acute apex.

Female. Coxite ( Fig. 11 View Figs ) with single broadly rounded apical lobe; stylus subapical, about 23 long as wide, bearing one long apical seta 2–33 length of stylus and one shorter apical seta nearly equal to length of stylus; stylus with two short preapical setae near midlength, one distal to other.

Type Material. Holotype: ♂ ( NMNH) with following label data: ‘‘PR: Caribbean Nat. For., El Verde , Elev. 370 M. scraping log with Stemonitis sp. JVMcHugh & PRFraissinet: PF90­0161, 14 June, 1990.’’ Paratypes: (1♂ AMNH; 1♂ ANIC; 1♂ BMNH; 1♀ NMNH; 1♀ FMNH; 1♂, 1♀ UGCA), with same data as holotype.

Etymology. Latin, meaning ‘‘twin,’’ in reference to the similarity of this species to C. leptosphinctos .

Distribution and Habitat. Known only from type locality in Caribbean National Park at El Verde in Puerto Rico. The lone collection was made from a fallen log in a mature, deciduous, tropical montane forest with a nearly closed canopy.
