Endaeus convexiculus Haran & Zelvelder sp. nov. urn:lsid:zoobank.org:act: 083F03C8-A62A-4851-B815-1D85D343B3D0 Fig. 10 Differential diagnosis Endaeus convexiculus Haran & Zelvelder sp. nov. is morphologically very close to E. baikieae, E. xylopiae Haran & Zelvelder sp. nov. and E. jaculifer Haran & Zelvelder sp. nov. It differs by having a longer and less downcurved rostrum. Males of the four differ greatly in the shape of their penis, that of E. convexiculus having ear-shaped lateral processes and an angled ‘three-sided’ profile. Among the species of Endaeus for which a barcode sequence is available, this species is closest to E. jaculifer, also found on Xylopia aethiopica (COI p- distance of 11.0%). Etymology This species is named in reference to its convex body shape in lateral view. Type material Holotype GABON • ♂; “GABON, Parc de la Lékédi / 26.x.2023 / J. Haran & R. Allio coll. / JHAR06086-07 / -1.778 13.000 [1°46′40.8″ S, 13°00′00.0″ E], 25m, 20h45 / Xylopia aethiopi. [ca] / Collection-Cirad / Holotype / Endaeus convexiculus Haran & Zelvelder 2026 ”; CBGP, JHAR06086-07. Description Male BODY LENGTH. 2.6 mm. COLOUR. Body integument uniformly pale brown, legs slightly lighter; vestiture of head, prothorax and elytra made of pale yellow to light orange setae, not concealing the integument; vestiture of prothorax and elytra made of a combination of short, subrecumbent setae, almost as long as interstriae, forming 3–4 ill-defined longitudinal rows on each interstria and long suberect setae, forming row on each interstria, 1.5–2.5 × as long as subrecumbent setae, as long as or longer than width of interstriae. HEAD. Head capsule with short, pale, subrecumbent setae and longer, pale suberect setae forming two ill-defined rows on forehead; rostrum slightly shorter than prothorax (0.83 ×) in lateral view, 3.4 × as long as width of eye, almost straight; antennae inserted near apical ⅓ of length of rostrum; eyes convex, strongly exceeding lateral curve of head capsule in dorsal view but not exceeding dorsal curve of head capsule in lateral view; space between eyes about ⅔ as wide as base of rostrum; antenna scape longer than segments 1–5 of funicle, widening at apical ⅓ of length; funicle with segment 1 globular; 2 twice as long as wide, 3–6 slightly wider than long; club slightly longer than wide (W:L ratio 0.55). PROTHORAX. Wider than long (W:L ratio 1.3), widest near middle of length, sides rounded, apical margin about 0.7 × as wide as basal margin; dorsum slightly convex in lateral view; integument shiny, micropunctuate, with uniformly distributed, medium-sized, roughly circular punctures; space between punctures as wide as diameter of punctures or larger; sides and apical margin of prothorax with erect setae pointing upwards and forwards, respectively; subrecumbent setae pointing towards inner line of prothorax on dorsum. ELYTRA. Sides slightly convex in dorsal view, widest near middle of length (W:L ratio: 0.83); humeri raised; interstriae 3–4 × as wide as striae; interstriae 10 widening from base to level of metacoxae, about 1.5 × as wide as interstriae 9 at widest point; in lateral view, dorsum of elytra gradually curves downward towards apex; interstriae 2 and 9 meet forming acute angle at apex; scutellar shield shiny, rounded. ABDOMEN. Underside covered with recumbent whitish setae longer than subrecumbent setae of elytra. LEGS. Femora subequal in thickness, thickened in middle of length, armed with flat triangular tooth, profemoral tooth followed by comb of 6 erect setae located between base of triangular tooth and distance from apex of femora equal to length of tarsomere 1; protibiae curved in basal ½, external margin straight in apical ¾, internal margin bisinuate, carinate, apex with long, robust, strongly curved mucro located medially on apex; apex of meso-tibiae with robust, slightly downcurved mucro located on inner part of corbel, erected almost perpendicularly; tarsal claws widely divergent, appendiculate with dull triangular inner tooth. TERMINALIA. Body of penis elongate (W:L ratio: 0.36), about 2.1 × as long as apodemes, sides subparallel, widest in basal ⅓, narrowing in apical 1 / 5, apex rounded, bearing anteapical comb of hairs of variable size on both sides; tip forming button-like shape; lateral extensions of body oriented ventrally, forming two small, translucent, ear-shaped extensions slightly longer than anteapical setae; curvature in lateral view moderate and regular on ventral side, three-sided on dorsal side, forming two right angles at apical ½ and apical ¼ of its length; internal sclerite not visible (Fig. 10C). Female Females of this species are currently unknown Life history This species was collected in the same conditions as E. xylopiae Haran & Zelvelder sp. nov., see details under that species. Distribution This species is currently only known for the type locality in La Lékédi park, in south-east Gabon (Haut-Ogooué Province). Its host is widely distributed in tropical Africa, from Senegal to Ethiopia and from Mozambique to Chad (WFO 2024).
