Head brown, lower half of frons, face, gena, and antennae yellow. Frontal width 2.2–2.3 × frontal height. Two pairs of strong interfrontal bristles surmounting a fine third pair; anterior orbital 0.4–0.5 × length of posterior. Palpus yellow. Eye large, greatest height about 3.5× shortest genal height. Thorax brown, scutum with paler lateral edges. Two pairs of dorsocentral bristles (anterior pair distinct, 0.4 × length of posterior pair) separated by 7–8 rows of acrostichal setulae. Membrane around prosternum bare. Legs yellow, hind leg slightly darker. Fore femur with three large ventral preapical setae. Ventral surface of male mid tibia with two rows of stout setae in apical quarter. Wing (Fig. 6C) slightly infuscate. CS2 0.5–0.6 × CS3. Halter pale brown. MALE ABDOMEN (Figs 42B–C, 43). Dark brown, posterior edges of tergites sometimes slightly desclerotized. T2–5 and S2–4 uniformly long-setose with large posterolateral setae. S5 rectangular, 1.2× length of S4, sparsely setose, slightly emarginate anteromedially with a dark, distally tapered, slightly bulging patch of dense setulae flanked by pale setose areas. Anterior flange of S6+7 large, 0.8× as long as wide. Sclerite A small, pale; sclerite B reduced, arched and fused to sclerite A; sclerite C reduced; sclerite D club-shaped, associated with inner posterior margin of S5; sclerite E well sclerotized, elongate, curved and slightly tapered; sclerite F large, subquadrate and laterally concave, left side with an elongate apicoventral process; sclerite G dark with a prominent, ridge-like process connecting to sclerite F; ring sclerite small, dark. Epandrium small, 0.5 × length of S8, height 1.3× maximum length and 0.8× maximum width, uniformly setose; anal fissure elongate; perianal pads weakly developed. Pseudocercus large, pale, bearing three setae and fused to posteroventral corners of epandrium; halves of subepandrial sclerite strongly arched, slightly flattened, and completely separate. Subcercus short but deep, subtriangular in posterior view, ventrally with a narrow, dark process, anterior part narrowed and carinate dorsally. Hypandrium with narrow anteromedial apodeme. Surstylus subquadrate, rounded, laterally setulose, ventrally setose, inner surface with anterodorsal lobe and a dark, bifurcate carina on dorsal half near middle. Postgonite short, broadened posteriorly into a broad triangle with a small, apical digitate process. Phallapodeme large, apex spoon-shaped; basiphallus small, slightly elongate with a flattened, triangular epiphallus; distiphallus reduced, largely membranous with a pair of pale Y-shaped lateral sclerites. FEMALE ABDOMEN (Fig. 44). T7 broad, simple; T8 divided into a small, pale, dorsal sclerite and two dark, lateral sclerites, posterolateral corners elongate and pointed. Epiproct broad, ovoid, medially split and entirely setulose. Cercus elongate, pointed with long apical and dorsal setae. S7 large, broad, posteriorly desclerotized with four large posterior setae; S8 well developed, deeply emarginate anteromedially, almost divided. Hypoproct with thick ventromedial setulae. Three spermathecae, bulb stout, bean-shaped, moderately striate with deep invaginations at apex and insertion point of duct (perpendicular to apex), both invaginations with a finger-like, central process. Distribution Neotropical: Costa Rica, Guatemala, Honduras, Panama, Tobago. Remarks Sclerocoelus dasysternum sp. nov. is superficially very similar to the closely related S. costaricensis sp. nov., but differs by the yellow gena, smaller eye (~3.5 × genal height), shorter second costal sector (0.5–0.6 × length of third), and two dark posteromedial patches of setulae on the male S5. Sclerocoelus dasysternum, a member of the mostly Central American S. dasysternum group, is one of four endemic Costa Rican Sclerocoelus.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
