Diagnosis. Adults of Loboplusia zurqui  are medium-sized and dark brown, which is darker than most other Diallactiini  of that size. Characters referred to in the generic diagnosis of Loboplusia  readily distinguish this species from other diallactiines with similar venation.

Description. Male. Body length 2.3–2.4 mm. Head. Genal setae (position indicated in Fig. 16 DView FIGURE 16 A – D) about 9, clustered. Eye bridge 0–1 ommatidium long dorsally. Scape and pedicel concolorous with flagellum, scape clearly larger than pedicel, with 4–5 setae, pedicel unsetose. Flagellomeres 14. Neck of fourth flagellomere ( Fig. 15 BView FIGURE 15 A – E) 1.2 times longer than node; node with short setae basally, a crenulate whorl with long sensory hairs with hooded alveoli medially, a short line of such sensory hairs ventrodistally, numerous short hair-like translucent sensilla distally, microtrichia everywhere. Clypeus unsetose. Labellum ( Fig. 16 DView FIGURE 16 A – D) very small, with no or 1 seta. Palpus ( Fig. 16 DView FIGURE 16 A – D) 1.2 times longer than head height, 4 segments, the two apical segments rarely fused into one, all segments with hair-shaped translucent sensilla. Thorax. Scutal setae sparse. Scutellum unsetose. Wing length / width 2.6 (fig. 15 D). Membrane completely covered with setae. Costal break indistinct; btv setose; both M 1 + 2 and M 4 absent; CuA extending to, or fading out before wing margin. Legs unicolored, without true scales. Setae of various lengths, shorter setae and almost all tarsal setae slightly broadened and fringed ( Fig. 15 EView FIGURE 15 A – E). Basitarsi without spine. Claws bent, untoothed. Empodia vestigial. Genitalia ( Fig. 15 AView FIGURE 15 A – E). Ninth tergite subtrapezoid, setose basally, microtrichose apically. Gonocoxae with mostly large setae, elongated ventroposteriorly into subtriangular lobes; ventral bridge unsetose; ventral emargination very large, U-shaped; dorsal apodemes interconnected to form a wide bridge without processes. Gonostylus large, lateral (or main) lobe thick thumb-shaped, bent dorsally, slightly tapered

apically towards (apex↓). Tegmen, with setae small of, weakly various sclerotized lengths, basomedial, broad-trapezoid lobe one. Ejaculatory third the length apodeme of lateral short lobe, weakly, with sclerotized strong tooth.

Female. Body length 2.8 mm. Head. Flagellomeres 14. Neck of fourth flagellomere ( Fig. 16 CView FIGURE 16 A – D) 0.8 times the length of node; node with long setae basally, in between a few short hair-like translucent sensilla, a few long sensory hairs with hooded alveoli medially, numerous short hair-like translucent sensilla distally, microtrichia dense basally, sparse elsewhere. Palpus thicker and longer than in male ( Fig. 16 BView FIGURE 16 A – D). Ovipositor ( Fig. 16 AView FIGURE 16 A – D) only slightly longer than eighth segment. Basicercus much larger than disticercus. No sclerotized spermathecae.

Etymology. The name refers to Zurquí  de Moravia in Costa Rica, the type locality of the new species, which in recent years has become famous among dipterists through the Zurquí  All-Diptera Biodiversity Inventory ( ZADBI) Project.

Type material. Holotype. Male (INB0004435502), Costa Rica, province San José, Moravia, Zurquí  de Moravia, tower path, 1,600 m, old-growth cloud forest, 1–7 June 2013, emergence trap over dry branches, ZADBI Project (in MNCRAbout MNCR). Paratypes. Male (INB0004435501), same data as the holotype; male (INB0004434841), female (INB0004434836), same data but 3–10 May 2013; male (INB0004381216), same data but 24–31 May 2013 (all in MNCRAbout MNCR).
