Distribution.

Central African Republic.

Etymology.

Named after the village Bayanga.

Diagnosis.

Belongs to the monophyletic Paramblynotus trisetosus clade, with Paramblynotus coxatus , Paramblynotus fuscapiculus , rwandensis, Paramblynotus trisetosus , Paramblynotus zairensis , Paramblynotus cameroonensis , Paramblynotus kekenboschi , Paramblynotus jacksoni , and Paramblynotus carinatus ( Liu et al. 2007). Median frontal carina almost extending to clypeus ( Figs 15A, 15C ). Ocellar plate defined by lateral carinae (two parallel carinae) delimiting the plate ( Fig. 15B ). Vertex with longitudinal carination as the dominant sculpture. Paramblynotus bayangensis is similar to Paramblynotus carinatus , but the ocellar plate does not have a row of relatively uniform large foveae along lateral carinae and instead has two parallel carinae defining the lateral edge ( Fig. 15B ). It can be separated from Paramblynotus kekenboschi and Paramblynotus zairensis by the more extensive median frontal carina which is distinct on the lower face, extending beyond lower margin of eyes and reaching the epistomal sulcus ( Fig. 15C ).

Description.

FEMALE ( Figs 14A-F , 15A-F ): Length 2.2 mm. Head and mesosoma black, metasoma dark brown; coxae, femora dark brown, tibiae and tarsi yellowish-brown ( Fig. 14A ). Wings clear ( Fig. 15E ). Antenna 13-segmented; flagellum thicker apically, distal segment longest and widest with three interspersed rows of multiporous plate sensilla (MPS); median flagellomeres constricted proximally and apically; grading from yellow distally to dark brown apically ( Fig. 14C ). Vertex with smooth area bordering carinae grading to areolet-rugose towards ocelli ( Fig. 14D ). Eye prominent, distinctly extended laterally beyond outer margin of genae ( Fig. 15A ). Ocellar plate raised and defined by two parallel lateral weak carinae delimiting the plate, posteriorly foveate, medially smooth ( Fig. 15B ). Median frontal carina distinct (but need right lighting to see it) in lower face, reaching to epistomal sulcus and bifurcated posteriorly to delimit a glabrous triangular area beneath anterior ocellus ( Figs 15A, 15C ). Antennal scrobe glabrous, defined by carina laterally. Whole face coarsely areolet-rugose with pubescence. Anterior tentorial pits distinct, situated in shallow depressions. Clypeus diagonally carinate laterally, with an anterior medial smooth excavation, foveate-rugose posteriorly ( Fig. 15C ). Genae coarsely foveate-rugose ( Fig. 14C ). Genal carina extending to behind dorso-posterior eye margin. Occiput glabrous. Anterior flange of pronotum glabrate. Anterior plate of pronotum glabrous and sparsely punctate anteriorly. Pronotum dorsomedially not distinctly raised; pronotal crest medially not raised into a process ( Fig. 14C ). Lateral pronotal carina distinct, almost meeting pronotal crest dorsomedially. Lateral surface of pronotum foveate-reticulate. Mesoscutum distinctly arched dorsally and foveate-reticulate with indistinct transverse costae ( Figs 14C-D ). Two scutellar foveae not subdivided by carinae; mesoscutellum foveate-reticulate and sloped posteriorly; posterior margin rounded in dorsal view ( Fig. 14D ). Mesopleural triangle ventrally well defined by smoothly curved carina and with white pubescence ( Fig. 14E ). Upper mesopleuron, including speculum, glabrous; median longitudinal impression present with unevenly distributed transverse carinae; lower mesopleuron glabrous and pubescent ventrally ( Fig. 14E ). Metepisternum foveate-reticulate and glabrous above, with an elevated glabrous, smooth area medially, and conspicuously pubescent ventrally ( Fig. 14E ). Propodeum overall areolate-reticulate; lateral propodeal carina present and distinctly curved medially; median propodeal area glabrate to rugulose; median longitudinal carina present, a transverse carina present anteriorly, and two submedian longitudinal carinae present posterior to transverse carina ( Fig. 14F ). Rs+M of forewing nebulous, arising from bottom third of basal vein ( Fig. 15E ). Marginal cell 2.3 times as long as wide. Bulla on Sc+R1 absent. Abdominal petiole 0.5 × as long as high in lateral view 0.33 × longer than wide in dorsal view, longitudinally carinate ( Figs 14C-D ). Relative length of T3-7: 14:7:8:28:8; T3-5 glabrous, smooth; T6 finely punctate with a medial row of long white setae; T7 punctate with an anterior row of long white setae; T8 entirely covered by T7 ( Fig. 15D ). All coxae and femora smooth shiny with pubescence; pro- and meso- tibiae and tarsi finely punctuate with pubescence; meta-tibiae and meta-tarsomeres densely punctate with pubescence ( Figs 14A, 14C , 15D ). Four apical teeth on metatibia. Proximal metatarsal segment 0.30 × length of distal 4 segments.

MALE ( Figs 16A-F ; 17A-B ): Length 1.8mm. Very similar to female, except for longer abdominal petiole, 1.54 × as wide as long in dorsal view, as long as high in lateral view ( Figs 16C-D ). Tergite 5 laterally expanded and by far the largest tergite, latero-medially 1.5 × longer than all other tergites combined ( Fig. 16D ).
