Caulophilus swensoni View in CoL nov.sp. ( Figs 13-17 View Figs 10-22 , 23-24 View Figs 23-28 )
H o l o t y p e: USNM 502877 (= Woodruff #5660), amber, Dominican Republic, Early Miocene (Burdigalian). P a r a t y p e: USNM 502666 (= Woodruff #5439), amber, Dominican Republic, Early Miocene (Burdigalian).
D i a g n o s i s:Rostrummoreorlessequalinlengthtolengthofpronotum ( Figs 23- 24 View Figs 23-28 ). Procoxae situated from posterior margin of prosternum by slightly less than coxal diameter and from each other by one length of a coxa ( Fig. 17 View Figs 10-22 ). Elytra with approximately 10-11 striae. Sparse, elongate setae on apical end of elytra ( Fig. 23 View Figs 23-28 ).
D e s c r i p t i o n: Total body length (including rostrum) ca. 3.77 mm; maximal width ca. 0.75 mm; elytral length ca. 1.69 mm. Integument dark brown to black (as preserved). Compound eyes subcircular, length approximately equal to width; interocular distance approximately equal to width of rostrum in dorsal view. Rostrum densely punctate, punctures minute, separated by distance 1-2✕ puncture diameter; rostrum more or less subequal to length of pronotum; ventral margin broadly and uniformly curved along entire length in lateral view ( Figs 13-14 View Figs 10-22 ); rostrum width subequal along length, widened slightly apically in dorsal view; rostrum bearing two long setae on inner apical surface. Antenna inserted immediately after mid-length of rostrum; scrobe long, extending just before compound eye; scape just reaching anterior margin of compound eye; scape slightly more than one-half length of rostrum; funicle narrow ( Fig. 15 View Figs 10-22 ), enlarging to a distinct, setose club. Vertex crenulate and punticulate. Pronotum glabrous, length approximately 1.2✕ width; anterior portion narrower than posterior portion; small, shallow punctures present, punctures separated by distance 1-2✕ puncture diameter; lateral margins broadly rounded. Prosternum with shallow depression between procoxae; small, shallow punctures present, punctures separated by distance 1-2✕ puncture diameter. Scutellum loosely triangular with corners rounded, small, length subequal to anterior basal width. Elytra each with approximately 10-11 striae; punctures of elytral striae small and shallow, separated by distance approximately 0.5-1✕ puncture diameter; humeri

subquadrate; a sparse covering of long setae at posterior quarter of elytra, setae approximately one-third to nearly one-half length of antennal scape. Metasternum and abdominal ventrites puncticulate. Femora widest at mid-length and puncticulate; profemora enlarged ( Fig. 16 View Figs 10-22 ); tibiae laterally expanded apically; apical tibial unci at outer angle large, approximately equal to length of tarsomere IV; a small denticle present on opposite side of uncus on inner angle, length equal to or slightly less than pretarsal claw length.
E t y m o l o g y: The specific epithet is a matronymic honoring Ms. Stephanie J. Swenson, distinguished coleopterist.
C o m m e n t s: This species is very similar to C. falini in overall body form, the elongate rostrum, and the presence of long setae apically on the elytra. Caulophilus swensoni can be differentiated from C. falini , however, by its larger body size, the longer scape length, the greater length of the pronotum in relation to the width of the pronotum, and the greater number of elytral striae.
