Lamtoana Dworakowska, 1972b: 853

Type species: Lamtoana sordida Dworakowska, 1972b , by original designation

Description. Body short to medium sized, mostly 2.5 to 3.5 mm. Head as wide as or slightly narrower than pronotum, crown fore margin rounded apically, coronal suture visible basally. Ocelli rudimentary with elongated, crescent-shaped vestiges. Face convex in profile. Pronotum with lateral margins slightly divergent posteriorly in dorsal view, hind margin weakly concave. Forewing ( Fig. 18a ) with first and third apical cell wide, second and fourth apical cell narrow, fourth cell not reached tip of wing, as long as or slightly shorter than third, AA fused with AP. Hind wing ( Fig. 18b ) with or without RA.

Male abdominal apodemes 2S broad, usually extended to sternite IV. Anal tube sclerotized distally, without appendage.

Male genital capsule cylindrical, moderately sclerotized. Pygofer lobe membranous dorso-apically, with distinct inner ridge between basal sclerite and distal membrane, with fine setae on middle and ventral part; dorsal appendage articulated to lobe, base enlarged, apical part thin, pointed distally; ventral appendage extended from lower distal angle of sclerotized part of lobe, thin or lamellate. Subgenital plate short but surpassing hind margin of pygofer lobe, angulately protruded subbasally, apical part rounded and pigmented, curved dorsad, with about 3–4 macrosetae in row near outer margin, with irregular rows of marginal microsetae from subbase to apex, basal ones distinctly thickened, with some microsetae scattered on distal disc. Style with apical part short, foot-like, preapical lobe enlarged, expanded medially, with some sensory pits subapically, basal part thick. Connective U-shaped, manubrium narrow to broad, usually without central lobe. Aedeagal shaft tubular, almost straight, base thicker than apex, with pair of thin processes apically; dorsal apodeme rudimentary to developed; preatrium moderately long, but shorter than shaft; gonopore terminal on ventral side.

Diagnosis. This genus is similar to Lublinia Dworakowska , but the pygofer lobe is membranous dorso-apically, the pygofer dorsal appendage is expanded basally, the apical part of the style is narrower and extended from the dorsal side of the preapical lobe, and the aedeagus has a well-developed preatrium.

Distribution. Canary Islands; Central African Republic; Republic of Congo; Ivory Coast; Uganda.

Remarks. This genus is a new recorded for Republic of Congo.
