Type locality. No type locality.
Diagnosis. The acutely notched external side of each clypeal tooth will place this species in Coprophanaeoides. Within Coprophanaeoides, the lack of basal elytral margin will separate it from all other species except its sister species D. compressipennis from which it differs in having a less dorsoventrally compressed body and in lacking a well-defined metasternal v-shaped ridge.
Description. Female holotype (Fig. 6). Body. Body moderately large, length 13.0 mm, maximum width 7.0 mm; body subrectangular in dorsal view; dorsum narrowly flat. Color. Dorsal surface black, glossy, with green metallic sheen; head with green metallic sheen on genae and frons; pronotum with green metallic sheen except for anteromedian carina, on anterior portion of disc and surface adjacent to lateral fossae; elytra with uniform green metallic sheen; ventrum with faint greenish and coppery metallic sheen; pygidium with green metallic sheen; legs with coppery and greenish metallic sheen on femora and tibiae. Head. Clypeus broadly arcuate laterally, straight on a short distance laterally to clypeal teeth, anterior portion upturned; clypeal teeth acutely triangular; clypeal median emargination narrowly v-shaped, clypeal edge acutely notched on external side of each clypeal tooth, clypeal teeth ventral surface lacking carina, clypeal margin ill-defined, bordered posteriorly by a more or less regular row of punctures, clypeal surface with transverse blunt rugulae; clypeogenal suture well-defined, bluntly carinate internally; genal surface with small irregular tubercles, lacking distinct transverse carina, simply convex; clypeofrontal carina rather low, approximately 4 times wider than high, slightly arcuate in dorsal view, simply carinate, clypeofrontal carina apical edge straight in frontal view; eyes large in dorsal view, interocular ratio 3.5. Pronotum. Pronotum transverse in dorsal view, pronotal width/length ratio 1.7; disc of pronotum minutely punctate with some scattered large setiferous puncture medially and irregular setiferous rough punctation anterolaterally, with an ill-defined shallow longitudinal depression on posterior half; pronotal anterior margin wider and flat lateral to eyes; anterior portion with a simple anteriorly arcuate carina; anterior angles surface with rough setiferous punctures, similar to lateral margin along posterior edge of anterior margin; lateral fossae oval, simple; lateral portions strongly explanate; pronotal basal fossae ill-defined, slightly concave; posterior margin well-defined laterally, crenulate, with few long setae. Elytra. Elytra approximately as long as wide in dorsal view, elytral combined width/length ratio 1.1; elytral base lacking distinct margin, simply convex; elytral striae 1–4 fine and well-defined, evenly impressed throughout, elytral striae 5 similar to 4 on disc, strial punctures fine, setiferous and scattered, adjacent strial edge encroaching on interval, stria 1 weakly impressed apically, going straight to elytral apical margin; interstriae slightly convex, minutely punctate and with few larger setiferous punctures along striae, surface glossy. Thoracic sterna. Proepisternal carina absent; metasternal median lobe bluntly angularly produced anteromedially, ventral ridge absent. Legs. Profemur posterior surface flat and glabrous internally, posterointernal margin rather thin, evenly developed, internal edge rather wide, with a contiguous row of setae along anterointernal edge and few scattered long setae on anterior half, remaining surface smooth. Protibia with four teeth on lateral edge; internal basal angle bluntly lobate; anterior surface with long aligned row of setae internally, surface glossy or feebly microsculptured between punctures; posterior surface with some ill-defined irregular punctures externally to median carina, surface glossy between punctures, with a single interrupted setal row along lateral teeth. Mesofemur angularly produced on anterointernal edge apically. Mesotibia rather short, gradually widening toward apex in anterior view; anteroapical edge straight in anterior view, anteroapical row of setae complete; apicoanterior edge circularly indented internally; external edge more or less flat, bordered anteriorly and posteriorly by an almost complete setal row. Mesotarsus similar in shape to metatarsus, 3- segmented, first segment moderately elongate, approximately two times as long as wide at apex. Metafemur internal edge nearly straight and lateral edge arcuate, lacking distinct depressed area anterointernally before apex, apicoposterior edge unmodified, anterior surface with a well-defined sulcus on more than half the length. Metatibia moderately slender, slightly widening toward apex in anterior view, anterior surface with distinct row of setae, surface glossy, metatibial posterior surface flat between longitudinal row of setae and lateral edge, with ill-defined microsculpture. Metatarsus 3-segmented, first segment moderately elongate, approximately two times as long as wide at apex, with anterointernal carina well defined and almost reaching apical edge. Abdominal sternites. Sternites 3–6 longitudinally flat; sternites 4–6 with more than three unaligned row of setae laterally, narrowly glabrous medially; sternite 7 approximately longitudinally flat medially, subequal in length to segment 6 along midline; pygidium minutely punctate on disc.
Measurements (1 male, 7 females). Length: male 15.0, female 13.0–15.0 (13.6±0.7) mm.

Natural history. Martínez & Clavijo (1990) report that M.J. Viana caught numerous specimens of D. hirticollis leaving a termite nest during a rain in Misiones, Argentina. A specimen from Minas Gerais was collected in a spider web under a street light.
Remarks. A single male of this species is known and differs from the females in having the anterior pronotal carina wider and somewhat atrophied medially in addition to having the abdominal sternites 5–7 almost completely setose. The parameres are simply rounded in dorsal view and the surface finely irregular apically (Figs. 50–51). Variation, as usual, the extent of the green metallic markings on head and pronotum varies. The Argentinean specimens differs in having the anterolateral surface of pronotum more simply convex and the pronotal disc less heavily sculptured between setose punctures as well as having the elytral apex more evenly convex with striae less impressed. For the moment this variation will be considered intraspecific.
