Horn, 1934 (by original designation).</p> <p>Revised differential diagnosis. Because of their extremely small to small, 5.4–7.5 mm long, black bodies, and 4–setose labrum, the four known species of the subgenus Microgeniatum may resemble some species of the subgenus Microstenocera Jeannel, 1946. However, in contrast to the irregular elytral setal vesture in Microstenocera, the species of Microgeniatum are characterized by their regular elytral setal vesture, consisting of ornamental se- tae, which are confined to punctures—each ornamental seta (microtrichia) arising from anterior margin of corre- sponding puncture (as in the nominotypical subgenus, which, however, houses species with much larger body with multisetose labrum). Elytra shiny black, notably coarsely punctate throughout, with smooth, glabrous intervals. Pronotal disc sculptured by coarse, or very coarse, transverse-wavy, or partly anastomosing ridges. Head temples moderately long, approximately 2 times shorter than eyes. Galea entirely black (or with slightly brownish apex of terminal galeomere). Labial palpi black, or partly or entirely testaceous. Antennae entirely black, or black-brown, or (in one species) predominantly ivory-testaceous. Legs with apical half of mesofemora, or also metafemora, more or less conspicuously subclavate-dilated, entirely black, except for one species with markedly bicoloured femora and tibiae. Aedeagus of various shapes.</p> <p>Nomenclatorial note. Because of their regular elytral setal vesture, species of the subgenus Microgeniatum had been treated by Olsoufieff (1934), Jeannel (1946) and Horn (1934) in the nominotypical subgenus Pogonostoma. When Rivalier (1970) established the subgenus Microgeniatum for the three above-mentioned species, he included also Pogonostoma gladiator W. Horn, 1934 there. Due to extremely distinctive diagnostic characters of Pogonos- toma (Hornogeniatum) gladiator (unique within the whole genus), the species was placed later (Moravec 2007) into a separate, monobasic subgenus Hornogeniatum Moravec, 2007.</p> <p>Distribution (Figs 11–14). Species of the subgenus are very rare, absent in most collections (including BMNH—see Moravec &amp; Gillett 2009). Behaviour of adults is similar to most species of the silvicolous and strictly arboreal genus; developmental stages unknown. Somewhat more common is only P. (Microgeniatum) pseudomini- mum W. Horn, 1934 (type species of the subgenus), which is known from eastern Madagascar (Antongil Bay, dis- trict of Maroantsetra), penetrating through the forest of the Mananara Nord National Park (Province of Toamasina) to central area of Central Highlands, through Antsianaka near Lac Alaotra and the forest of Didy (both in the district of Ambatondrazaka) up to the forest of Analamazaotra-Perinet (type locality) east of Moramanga. The syntypes (1 ♂, 1 ♀, lectotype not designated) of P. (Microgeniatum) pseudominimum are deposited in SDEI; other specimens examined are in MNHN, CCJM, CJVB and JWCW (Moravec 2007 and recent personal data). The following two species have not been confirmed recently. P. (Microgeniatum) flavopalpale Jeannel, 1946 is known only from one male and one female (MNHN), caught in the forest of Piton Saint-Louis, north of Tolagnaro (= Fort Dauphin), 121 years ago. Only the male holotype (MNHN) of P. (Microgeniatum) infimum Rivalier, 1970 exists; it was caught in the deciduous forest of Analamerana, 50 km south-east of Antsiranana (= Diego Suarez) in northern Madagascar (in January 1959). Finally, P. (Microgeniatum) signifemorale sp. nov. is known only from the single male caught recently in the dense, dry deciduous forest of the Ankarafantsika National Park in northwestern Madagascar.</p> </div>	http://treatment.plazi.org/id/038987BBFFD75825FF5DFC50FA87DECD	Public Domain	No known copyright restrictions apply.

Northwestern Madagascar: dry deciduous forest of the Ankarafantsika National Park, “Tour du Lac” (Ambato Boeni Region, Province of Mahajanga).</p> <p>Type material. Holotype in NMPC (temporarily in JVCB), labelled: “NW Madagascar, 71 m, / Ankarafan- tsika N.P., Tour du Lac / S 16°18´13.0´´; E 46°48´49.1´´, / 23.- 26.i.2015, M. Trýzna leg.” [printed] // “Pogonos- toma / (Microgeniatum) / signifemorale sp. nov. ” / det Jiří Moravec / &amp; Miloš Trýzna 2021 ” [red, printed].</p> <p>Differential diagnosis. By its extremely small body and boomerang-bent aedeagus with similarly shaped apex, P. (M.) signifemorale sp. nov. may resemble P. (M.) infimum. The new species is immediately distinguished from it, however, and from other three species of the subgenus by its markedly bicoloured meso- and metafemora (Fig. 1) with their basal third yellow, while their remaining, markedly dilated portions are black; moreover, also the basal area of all tibiae is yellow. Antennomeres of the new species are uniquely coloured as well: the scape is black dorsally, yellow-testaceous apically; antennomeres 2–4 ivory to yellow-testaceous (Figs 1, 3–4). In contrast, the femora and tibiae, as well as the antennae of P. (M.) infimum are uniformly black or black-brown (Moravec 2007, fig. 1819); the other two species also possess black femora, tibiae and antennae. In addition, the surface of the pronotal disc of the new species is covered with finer rugae (Fig. 8) than the coarser and more almost subreticulateanastomosing ridges on the pronotum of P. (M.) infimum (see Moravec 2007, fig. 1621). Moreover, the aedeagus of the new species is more abruptly bent above the middle and wider in the point of the angle (Fig. 5), while the angle is arcuate in P. (M.) infimum (see Moravec 2007, fig. 1622); the aedeagi of other two species are very differently shaped. For other differences see “Key to species” above, and the detailed redescriptions and illustrations in the monograph of the genus (Moravec 2007).</p> <p>It should be mentioned here that also P. (Microstenocera) sicardi W. Horn, 1927 may superficially resemble the new species by its yellow femoral bases; however, the yellow area is much less expanded and apart from the irregular elytral setal vesture (diagnostic for Microstenocera), P. (Microstenocera) sicardi differs in a complex of other characters including the very different shape of its aedeagus (see Moravec 2007).</p> <p>Description (male holotype).

Coxae black, trochanters testaceous; profemora voluminous, black, except for yellow base; meso- and metafemora with basal third yellow, remaining portion black and subclavate-dilated towards constricted apex; basal quarter or third of all tibiae yellow; tarsi brownish to black-brown, claws testaceous; setal vesture of legs inconspicuous: femora glabrous, tibiae and tarsi covered with usual, rather dense microsetae.</p> <p>Aedeagus (Fig. 5) abruptly boomerang-bent above middle, length 1.10 mm, width 0.20 mm, apical portion rather wide, notably dilated in the dorsal angle, conical-constricted towards blunt apex which is ventrally arcuate, dorsally very slightly emarginate, thus slightly directed dorsad; in its dorsal (and ventral) aspect the apical portion appears gradually conical-constricted towards blunt apex.</p> <p>Distribution and habitat (Figs 9–10, 14). Known only from the male holotype caught by the second author in the dense, dry deciduous forest of the Ankarafantsika National Park (previously known as Ampijoroa Forest Station, see Viette 1991) near Marovoay, northwestern Madagascar (Ambato Boeni Region, district of Mahajanga). The only male was caught along the tracking path “Tour du Lac” in a margin between primary and secondary forest when running along a surface of an almost horizontal fallen twig of about 10 cm in diameter (Fig. 9, bottom). No other adult was observed in the area despite an intense search. Unfortunately, due to serious bushfires which have recently afflicted some of the Madagascan protected areas, including the Ankarafantsika National Park (see Bezain 2021, Vyawahare 2020), the chance of finding other adults of the new species appears even more improbable.</p> <p>Etymology. Derived from Latin signo [signum] = marked, referring to the markedly bicoloured femora of the new species.</p></div> 	http://treatment.plazi.org/id/038987BBFFD6582EFF5DFB00FEF7DC3D	Public Domain	No known copyright restrictions apply.
