A single specimen of this species collected by Charles O’Brien was designated a Cyrtosoma (Pachycyrtosoma) merkli paratype by Marcuzzi in 1999 (now Nesocyrtosoma merkli [Marcuzzi]). However, after examination of this specimen, it has been determined that this specimen is not N. merkli , but rather N. otus , and is included as a paratype of N. otus . Diagnosis. This species can be easily distinguished by its large size, the anterior angles of the pronotum acute, extremely produced, and weakly concave ( Fig. 159 ), the prosternal process flat and widely rounded, the mesoventrite nearly flat ( Fig. 160 ), meso- and metatibia club-like at apex ( Fig. 54 ), and abdominal depressions on 4th and 5th ventrites present as deeply impressed pits ( Fig. 75 ). Description (male). 8.5–12.0 mm long, 4.5–6.5 mm wide. Body elongate, moderately convex ( Figs. 157, 158 ). Purple to black; antennae, mouthparts, and tarsi ferrugineous. Head densely punctate, punctures smaller than a single eye facet and lightly impressed; extremely short golden seta emerging from each puncture. Antenna weakly clavate, nearly filiform; antennomeres 6–10 weakly widened apically, forming a loose, elongate club; apical antennomere longitudinally ovate; antennomeres 6–11 with stellate sensoria. Mentum with broad median keel raised anteriorly to a point; area laterad keel weakly concave ( Fig. 13 ); ventral portion of eye reaching subgenal sulcus ( Fig. 9 ); postgena without distinct punctures. Dorsal surface of pronotum densely punctate; punctures separated by,0.5–0.5 diameters. Pronotal marginal bead complete laterally, anterior and posterior margins with marginal bead effaced medially; anterior angles of pronotum acute, strongly produced and apically narrowly rounded; area around anterior and posterior angles weakly concave; lateral edge of pronotum sinuate at base ( Fig. 159 ). Hypomeron without distinct punctures. Prosternal process broad, flat, apically rounded; distinct marginal grooves opposite coxae not joined apically ( Fig. 160 ). Elytral striae not impressed, present as small discontinuous punctures; punctures separated by 0.5–1.0 diameters; appearing as a fine stria; elytral interstriae flat; densely punctate; scutellary striae weakly impressed, 4–6 punctures long; scutellum triangular, normal ( Figs. 157, 159 ). Mesoventrite thin antero-posteriorly, nearly flat medially, weakly raised laterally, widely U-shaped, receiving prosternal process; metaventrite subequal in antero-postero length of mesocoxa ( Fig. 160 ). Metathoracic wing fully developed. Legs long, slender, punctate, apical portion of femur reaching beyond elytron; tibiae apically curved ventrally; meso- and metatibia with ventral apical tooth very broad causing the meso- and metatibia to appear club-like, ( Fig. 54 ). Abdominal depressions on 4th and 5th ventrites present as deeply impressed pits ( Fig. 75 ); intercoxal process of first ventrite broadly apically rounded; ventral surface densely punctate; punctures weakly impressed; ventrites I–III with lightly impressed longitudinal grooves ( Fig. 160 ). Female. Identical to male, except with meso- and metatibiae straight. Biology. This species has been taken during the day and at night. It has been collected in high elevation pine forest beating dead branches, on dead logs, in rotten logs in moist forest, and beating vegetation at night. It has also been taken in a flight intercept trap and at blacklight. Distribution. This species is endemic to Hispaniola. It has been taken on Mt. Diego de Ocampo at 915–1,220 m ( 3,000 –4,000 ft ) elevation on Santiago Province , Mt. Quita at 610–915 m ( 2,000 –3,000 ft ) elevation in Duarte Province , Los Tablones in Parque Nacional Armando Bermudez, La Cienaga and south of Constanza in La Vega Province , and Los Tablones on Pico Duarte Trail in Ázua Province , all of the Dominican Republic ( Figs. 260 , 263 ). This species has also been taken in the northeast foothills of La Hotte at 610–1,220 m ( 2,000 –4,000 ft ) elevation in du Sud Department , Haiti ( Figs. 261 , 263 ). Etymology. The species epithet, used as a noun in apposition, is from the Latin word otus , which is derived from the Greek word, v´Tóz, meaning the eared or horned owl. This species has a pronotum that resembles the head of an owl, having the anterior angles acute and extremely produced, much like the ears of an owl. Nesocyrtosoma darlingtoni Hopp and Ivie , New Species ( Figs. 9 , 55 , 161–164 , 262 , 286 ) Type Material. HOLOTYPE : Male.

This species can be distinguished by the combination of antennomeres 7–10 weakly widened apically, the apically rounded prosternal process ( Fig. 164 ), circular punctures on the hypomeron ( Fig. 27 ), impunctate interstriae ( Fig. 161 ), and males with small ventral apical tooth on metatibia. It closely resembles N. dolosum , but can be distinguished from that species by the prosternal process declivous behind ( Fig. 164 ), antennomeres 7–10 weakly widened apically, and males lacking a ventral setal patch. It also closely resembles N. mutabile , but can be distinguished from that species by the more slender body ( Fig. 161 ), deeply excavate mesoventrite ( Fig. 164 ), and the elongate pronotum with more acute, produced, and narrowly rounded anterior angles ( Fig. 163 ). Finally, it is also similar to N. altagracia , but can be distinguished from that species by the deeply excavate mesoventrite ( Fig. 164 ). Description (male). 7.5–8.5 mm long, 4.0– 4.5 mm wide. Body elongate, slightly convex ( Figs. 161, 162 ). Glossy dark ferrugineous to purple; antennae, mouthparts, and tarsi tending to be the same color as the legs. Head densely punctate, largest punctures subequal in size to single eye facet and moderately impressed; extremely short golden seta emerging from each puncture. Antenna weakly clavate, nearly filiform; antennomeres 7–10 weakly widened apically, forming a loose, elongate club; apical antennomere longitudinally ovate; antennomeres 7–11 with stellate sensoria. Mentum with acute median keel raised anteriorly to a point ( Figs. 10, 12 ); ventral portion of eye reaching subgenal sulcus ( Fig. 9 ); postgena with distinct punctures ( Fig. 12 ). Dorsal surface of pronotum densely punctate; punctures separated by 0.5–1.0 diameters. Pronotal marginal bead complete laterally, anterior margin with marginal bead effaced medially, posterior margin lacking marginal bead; anterior angles of pronotum acute, produced and apically narrowly rounded; lateral edge of pronotum sinuate at base; pronotum evenly convex ( Fig. 163 ). Hypomeron with distinct punctures ( Fig. 27 ). Prosternal process apically rounded, declivous behind; indistinct marginal grooves opposite coxae not joined apically ( Fig. 164 ). Elytral striae not impressed, present as small discontinuous punctures; punctures separated by 0.5–1.0 diameters, appearing as a fine striae; elytral interstriae flat; densely punctate, punctures weakly impressed; scutellary striae 4–6 punctures long, nearly reaching the elytral suture; scutellum triangular, normal ( Figs. 161, 163 ). Mesoventrite thin antero-posteriorly, deeply excavate, V-shaped, receiving prosternal process; metaventrite subequal in antero-postero length of mesocoxa ( Fig. 164 ). Metathoracic wing fully developed. Legs long, slender, punctate, apical portion of femora reaching beyond elytron; meso- and metatibia with small ventral apical tooth ( Fig. 55 ). Abdominal depressions on 4th and 5th ventrites present as weakly impressed pits ( Fig. 75 ); intercoxal process of first ventrite apically triangular; ventral surface densely punctate, punctures weakly impressed ( Fig. 164 ). Female. Identical to male, except tibiae straight and lacking meso- and metatibial tooth. Biology. Unknown. Distribution. This species is endemic to Hispaniola. It has primarily been collected at 610–1,220 m ( 2,000 –4,000 ft ) elevation in the northeast foothills of La Hotte, as well as at 1,220 m ( 4,000 ft ) in Desbarriere and 915 m ( 3,000 ft ) in Tardieu, also part of the Tiburon Peninsula of Haiti ( Figs. 261 , 262 ). Etymology. This species is named for Philip J. Darlington , the collector of this species and many others on Hispaniola.
