Type material. Holotype: Female. Type locality: Dominican Republic, Provincia de La Vega, La Cienega de Manabao. Park Hdqt. , 3–5-VII-99, 3,000, elev., R. E. Woodruff, blacklight ( FSCA) . Paratypes. 7 specimens. Dominican Republic, Provincia de La Vega, La Cienega de Manabao. Park Hdqt., 3–5-VII-99, 3,000, elev., blacklight, R. E. Woodruff ( FSCA, 6). Dominican Republic, Provincia de Santiago, Mount Diego de Ocampo, 3–4,000, IIV-1938, Darlington ( MCZC, 1).

Diagnosis. The base of the femur and trochanter are yellow, the remainder of the is leg black. These characteristics will distinguish the members of this species from congeners.

Description. Size. Length 5.5 mm; width 1.8 mm. Form. As in Fig. 17 Color. Body bluish, trochanter yellow, remainder of leg black. Head. Cranium finely punctate, frons much wider than length of pedicel; EW/FW 15/40. Thorax. Pronotum finely transversely wrinkled, oblong, expanded at middle 1/2; subapical depression faintly expressed; collar narrow; PW/PL 65 /70; elytral punctations striate, striae reduced near elytral apex; EL/EW 250/100; short elytral setae decumbent, long elytral setae recumbent. Abdomen. Aedeagus not available for study.

Variation. Size. Length 4.0–5.0 mm; width 1.5–1.8 mm. Other than body size, the available specimens are quite homogenous.

Distribution. This species is known from the Dominican Republic.

Etymology. The specific epithet, woodruffi , is a patronym that honors Robert E. Woodruff for his many accomplishments in systematic entomology.

Species Minimally Defined

The Cuban Cleridae insect collection of Fernando de Zayas is not available for study. However, it is possible to glean some of the clerid characteristics described by de Zayas. The species discussed by de Zayas (1988) are minimally described, and are only based on the descriptions noted and the available illustrations provided. Therefore, I offer very abbreviated descriptions of the following Onychotillus species: O. cubana de Zayas , O. dimidiatus de Zayas , and O. trinitatis de Zayas.

Burke and Zolnerowich (2017: 138) redescribed O. cubana de Zayas in their publication of Tillinae . However, it is not known whether their redescription of O. cubana de Zayas represents a true specimen of that species. All the specimens of Onychotillus , and illustrations, which I am aware of fall into no more than 6.0 mm.
