Makilingia tenebrifrons n. sp.

( Figs 2 Q–R, 7K–O, 8Q, 9GG–HH)

Description. Length of male 6.4–7.0mm; female 7.0– 8.1mm. Coloration. Golden yellow overall. Crown with pair of anterior triangular black maculae, pair of median maculae extended from eyes mesad to cover ocelli; face sexually dimorphic, males with frontoclypeus black except for small yellow median dorsal spot, females with central part of frontoclypeus yellow and with longitudinal black band next to laterofrontal suture, anteclypeus black. Pronotum with pair of anterolateral black maculae, mesonotal triangles black; thoracic pleurites black. Stucture. Head relatively short with anterior margin of crown in dorsal view evenly rounded; face with frontoclypeus and anteclypeus shagreen, clypeal suture poorly delimited, anteclypeus in profile obtusely angulate; distinct punctations restricted to genae. Forewing venation moderately well delimited, without supernumerary branches or crossveins. Male genitalia. Pygofer appendage slender, evenly curved dorsad, extended well beyond lobe apex. Subgenital plate moderately long, evenly curved dorsad, basal section broad and darkly sclerotized, distal section slender with dark pigment in distal half, dorsal callosity long and moderatly produced dorsad. Style without preapical lobe, apex footlike with distinctly acute heel and moderately long slender toe. Aedeagus in lateral view with preatrium as long as shaft, strongly curved, atrial processes oblique, shaft beanlike, without conspicuous teeth or ridges; in posterior view fleur-de-lis shaped with preatrium constricted medially, atrial processes broad and arcuate, shaft elliptical with narrow apical median cleft.

Etymology. The species name combines the Latin "tenebricus" (dark) with "frons" and refers to the mostly black face.

Material examined. Holotype male labeled “Imugin / N. Viscaya / Baker; Cotype No./ U.S. N.M.; HOLOTYPE / Makilingia tenebrifrons / Dietrich & Zahniser / 2019; USNMENT / 01513247” . Paratypes: 2 males, 4 females, same data ; 2 males, 5 females labeled “Baguio / Benguet / Baker; Cotype No / U.S. N.M. All paratypes with identification label and USNMENT barcode label numbered 0 1513205, -209, -211, -215, -220, -221, -222, - 226, -228, -230, -237, -238, -246, and -248.

Notes. This species closely resembles M. tettigonoides and the type specimens were included by Baker in his type series for the latter species. However, M. tenebrifrons is easily distinguishable by the distinct coloration of the head and by the male genitalia.
