Empis (Enoplempis) delnortensis sp. nov. urn:lsid:zoobank.org:act: 54F6925E-47DF-4EC9-8160-606EDF632C11 (Figs 304, 306, 308) Type material. HOLOTYPE ♂ (Fig. 304), labelled: “USA: CA: Del Norte Co. / West Fork of Patrick Crk. / N 41°55′03″ W 123°51′28″/ 24-31.V.2009, Malaise/ J.M.Cumming & S.E.Brooks ”; “ CNC/ 1078381 ”; “ HOLOTYPE / Empis (Enoplempis) / delnortensis Sinclair,/ Brooks & Cumming [red label]” (CNC). PARATYPES: USA. California: Del Norte County: Same data as holotype (1♂, 1♀, CNC). Diagnosis. This species is distinguished from other species of the subgenus by the grey body (Fig. 304) and males are holoptic, with hindleg unmodified, hind tarsomere 1 somewhat inflated, hind tibia with several pairs of anterodorsal and posterodorsal setae, less than twice as long as tibia and cercus straight dorsally, with tapered apical half (Fig. 306). Description. Wing length 3.8–4 mm. Male. Similar to E. (En.) californica sp. nov., except as follows: head holoptic. Occiput bearing single row of slender setae, similar in size to ocellar setae. Antenna with postpedicel long and tapered, 5× longer than basal width. Thorax with antepronotum with several pairs of dark setae. Postpronotum with 1 long seta and several short, dark setae. Scutum with uniserial acr; dc slightly longer than acr, increasing in length and stronger posteriorly; 1–2 posterior npl, with 1–2 short, fine anterior npl. Legs long, slender, yellowish brown, gradually becoming darker apically; coxae with or without dense greyish pruinescence (Fig. 304). Mid and hind femora with white ventral pile, longest on hind femur. Fore femur with anteroventral and posteroventral row of setae, shorter than half width of femur. Fore tibia with 1–2 anterodorsal setae on apical half; without erect posterior setae; dorsal and ventral preapical setae present; anterior face with short appressed setae. Fore tarsomere 1 slender without long dorsal setae, with fine dense ventral setae, with 1–2 pairs of stronger ventral setae on apical half; tarsomeres 2–5 with biserial row of strong ventral setae; tarsomeres 1–4 with apicolateral pair of spine-like setae, longer than width of segment. Mid femur similar to fore femur. Mid tibia with 2 pairs of erect anterodorsal and posterodorsal setae on basal half; apical quarter with strong ventral setae. Mid tarsomere 1 without long dorsal setae; tarsomeres 1–5 with biserial row of spine-like ventral setae; tarsomeres 1–4 with apicolateral pair of spine-like setae, longer than width of segment. Hind femur slender without modified setae and processes; row of fine anteroventral and posteroventral setae, length longer than width of femur; single dark anteroventral seta on apical quarter. Hind tibia without processes or modified setae; 4–5 erect anterodorsal and posterodorsal setae evenly distributed along length of tibia, length slightly longer than width of tibia; without long anterior and ventral setae. Hind tarsomere 1 somewhat inflated with several long dorsal setae, similar to tibia, otherwise similar to mid tarsus. Wing slightly infuscate; veins mostly complete (except Sc), CuA+CuP very weak and fading out well before wing margin. Halter whitish to pale brown (Fig. 304). Abdomen paler than thorax, with greyish pruinescence; sclerites of segment 8 fused anterolaterally. Terminalia (Fig. 306): epandrium and cerci dark brown; phallus orange brown and shiny. Cercus subtriangular, with straight dorsal margin, tapered posteriorly with truncate apex; setae shorter than width of cercus. Subepandrial process extending on either side of phallus. Epandrium expanded on basal half, not linear, longer than height; posterior margin distinctly upcurved, bearing long setae ventrally, shorter than width of epandrium. Hypandrium narrow, strap-like; without setae. Phallus with basal half not strongly expanded, tapered apically, with distinct bend near apical quarter; apex emerging beyond cerci; phallus with broad apex, with roughened surface encircling tip; ejaculatory apodeme narrow, more than half-length of epandrium, Y-shaped, with lateral apodemes positioned near ventral margin with short medial apodeme. Female. Similar to male, except as follows: frons broader, wider than anterior ocellus; legs stockier, without modified setae and processes. Abdominal pleural membrane without darkened, expanded region; tergite 8 (and likely syntergite 9+10) with pruinescence. Geographical distribution and seasonal occurrence (Fig. 308). Empis (En.) delnortensis sp. nov. is known only from the type locality in Del Norte County, California. Adults have been collected in May. Etymology. The species is named after Del Norte County in northern California, where all the type specimens were collected. Nuptial gift presentation. Form unknown.

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.
