Diagnosis. The elytral spot not extending onto 3rd interstria, and not reaching elytral base, as well as the deeply punctate but weakly indicated 7th stria will distinguish this species, as will the unique shape of the apex of the male genitalia (Fig. 11).
Description (male). Body oval (Fig. 20); finely pilose; shining; whitish-yellow spot on each elytron from 8th stria to laterad edge of 3rd, not quite reaching base of elytra, shape irregular, anterior margin bulging forward on 3rd and 5th interval, posterior margin reaching posterior maximum on 4th or 5th interval (Fig. 8); eplipleuron with small whitish-yellow spot adjacent to elytral spot, rounded and not reaching mesal margin; apical portion of elytron without whitish-yellow spot. Eyes dorsally separated by 5X maximum width of dorsal lobe (Fig. 5). Labium with apex emarginate, palpomere 2 without beard internally; base of mentum bearing 2 very long setae (Fig. 2). Pronotum as wide as base of elytra; lateral margins nearly parallel for 4/5th s from base, rounded inwardly in apical 1/5th; basal margin distinct except medially. Elytral striae 1–6 impunctate, consisting of 2 parallel lines, stria 6 obsolete on elytral spot, stria 7 indicated by few coarse punctures at mid-length, 8th punctate and impressed; interstria very weakly domed on disc, mainly conforming to shape of elytron. Foretibia weakly obliquely truncate apically, with 2 acute teeth externally; serrulate between and proximal to teeth, apical spur stout, wide toward apex (Fig. 14). Metatibia weakly serrulate on internal margin (Fig. 17). Adeagus with shape of phallobase apex and parameres unique, as in Fig. 11.
Female: differs from male in lacking serrulations on internal margin of metatibia and the tapering apical spur of the protibia.
Length: 3.0–4.7 mm, measured along midline from anterior margin of pronotum to tip of elytra.

Etymology. Quesqueya is the name for Hispaniola in the indigenous Taino language. It is here considered as a noun in apposition.
Notes. The majority of specimens examined were taken near La Cienaga, in the Cordillera Central, at elevations near 1,000 m. As with most of the small scarabaeines of Hispaniola, the majority of specimens were taken in flight intercept traps, but a few were taken at carrion and in leaf litter. One intriguing specimen is from a broken termite nest at lower elevation. Interestingly, most of the specimens taken at carrion were males (10 of 17) but in FITs the ratio is reversed, where only 7 of 25 being males.
