Holotype ♀ (Fig. 1A) (originally described as male). Body length 2.7 mm; wing length 2.8 mm. Head narrowly dichoptic. Inferior facets slightly larger than superior ones. Frons shiny brown slightly wider than anterior ocellus width, narrowing ventrally. One pair of proclinate ocellar setae. Face gray pruinose, slightly narrower than frons, narrower medially, slightly higher than frons. Postcranium shiny brown to black, slightly gray pruinose, except on postocular margin.

Antenna with pedicel yellow to brown, postpedicel velvety dark brown to black, short setulose. Proboscis yellow, as long as head height. Thorax shiny black; pruinosity, depending on angle of light incidence, slightly more distinct on disc of scutum, scutellum and mediotergite. Thoracic chaetotaxy: setae somewhat damaged, 2–3 antepronotals weak; 1 postpronotal; dorsocentrals damaged (probably four); 1 presutural supra-alar; 0 postsutural supra-alar; 1 postalar; 1–2 proepisternals; 1 notopleural; scutellars damaged (probably two pairs); 2–3 laterotergitals. Legs (Fig. 1A) mainly yellow except apex of fore tibia, fore tarsomere 5, apex of mid tibia, distal mid tarsomeres, apex of hind femur, distal half of hind tibia and almost entire hind tarsus dark brown to black. Legs longer setae: mid tibia with 1 anteroventral and 1 posteroventral stouter; hind leg (Fig. 1B): hind femur with 1 anterior sub-basal, 1 anteroventral on distal third, both short but distinct; hind tibia with 4 longer dorsal setae with 1 at basal third and 3 on distal half; hind tarsomere 1 with 1 median dorsal seta.

Macrostomus apicalis was described from a single female specimen from Peru, Pichis River, Puerto de Yesup (SNSD, examined by JAR about 30 years ago). Since then, no additional conspecific specimens have been found in collections, so the redescription of this species is included here, with the original unpublished photos of the type specimen. Macrostomus apicalis is the last species of Macrostomus described by Bezzi (1905, 1909) not yet redescribed. Unfortunately, it is in poor condition and the genitalia was not studied and the association with male specimens from the type locality is necessary to facilitate the recognition of this species. The type specimen is externally remarkably similar with M. melanothorax (see below) and it will be necessary to study the female genitalia of the holotype of M. apicalis (unfortunately not drawn 30 years ago) to confirm a possible synonymy between both species.</p> <p>+ CuP posterior branch of cubital vein; dm —discal medial cell; dm–m —discal medial crossvein; M 1 —first branch of media; M 2 —second branch of media; M 4 —fourth branch of media.</p></div> 	http://treatment.plazi.org/id/03F5878CFFC2FFFD75D1A96AC49AA8EA	Public Domain	No known copyright restrictions apply.

In the same paper it was recorded from Peru. The Peruvian specimen (Fig. 2) differs from the Bolivian female holotype as follows: mesonotum mainly brown (versus mainly yellow in the holotype); hind tarsomeres 1–4 whitish to silvery (versus only tarsomere 1 whitish to silvery); wing with distal section of vein M 4 longer than vein dm-m height (versus same height of vein dm-m). Currently this species is known only from female specimens and despite these differences we tentatively prefer to consider the specimens from Bolivia and Peru conspecific until males from both locations are studied. This is essential in order to be confident that the Peruvian specimens are conspecific with Bolivian specimens.</p></div> 	http://treatment.plazi.org/id/03F5878CFFC1FFFC75D1AF09C4A2ACA2	Public Domain	No known copyright restrictions apply.

Macrostomus chelicercus sp. nov. is best placed in the M. amazonensis species-group as described by Rafael &amp; Cumming (2015). In the key presented by Rafael &amp; Cumming (2015) it runs to couplet 2 of M. acreanus Rafael &amp; Cumming, 2015 by having the mesopleuron yellow. Both species have a short tergite 8 with shallow basal sinus. Macrostomus chelicercus sp. nov. differs by the cercal bridge U-shaped (versus dome-shaped in M. acreanus), anterior cercus subtriangular (versus longitudinally elongate), posterior cercus inward and forward directed with apex bifid (versus vertically elongate with apex simple). Nevertheless, Macrostomus chelicercus sp. nov. appears to be more related with M. xavieri Rafael &amp; Cumming, 2015 by the short tergite 8 with shallow basal sinus, mesial process of anterior cercus small and posterior cercus inwardly curved. Macrostomus chelicercus sp. nov. differs by cercal bridge U-shaped (versus somewhat bilobate in M. xavieri), anterior cercus subtriangular (versus vertically elongate), posterior cercus inwardly and forwardly directed with apex bifid (versus inwardly curved with apex simple). Additionally, M. chelicercus sp. nov. differs from both species by the distinctly crooked hind femur, with denser, short, stouter dorsal and ventral setae at curved area and by the slightly curved mid and hind femora and tibiae. In CNC, there is an additional new species which keys to M. chelicercus sp. nov. (B.J. Sinclair pers. comm. 2020).

Characters allowing a well-founded species-group placement are presently not available for M. hyalopteryx sp. nov. It appears to be related to M. trilineatus Rafael &amp; Marques, 2019, described from Bolivia, as both species share the narrow postcranium, shape of male tergite 8 with short projection distally, with apex rounded and when seen in lateral view with distinct ventral keel connected to cercal bridge, multilobate anterior cercus, epandrium with stout setae distally and by the ventral projection of the cercus projected ventrally, each branch parallel sided to each other, with distinct posterior setae medially. It differs by the thorax entirely shiny black (versus thorax shiny yellow with three longitudinal black stripes on mesonotum in M. trilineatus), wing entirely hyaline (versus wing light brown infuscate along costal margin, darker at pterostigma), abdomen shiny black with blue reflection at certain angles (versus abdomen shiny black, except basal sternites yellow, without blue reflection), epandrium posterodorsal lobe with two short, stout setae distally (versus posterodorsal lobe with two stouter, spatulate apical spine–like setae besides other slender setae). At a glance, this species is somewhat similar to species of Porphyrochroa Melander by the abdominal blue reflection and short cell dm.

HOLOTYPE ♂, PARATYPE ♀, same pin, labelled: “ PERU, Junin, Oxapampa, 1700 m ” / “in copula, Oxapampa, 6.iii.[19]79” / “QR code: NHMUK 010864610” / “ Holotype ♂, Paratype ♀, M. unilineatus Rafael &amp; Marques ” (Fig. 13P) (NHMUK). PARATYPE: Same data as holotype, except 8.iii.[19]79 / “QR code: NHMUK 010864611” / “ Paratype ♀ Macrostomus unilineatus Rafael &amp; Marques ” (1 ♀, NHMUK).</p> <p>Holotype condition. Pinned, double mounted. Wing with small broken piece between veins M 4 and CuA+CuP. Abdomen dissected, stored in microvial with glycerin.</p> <p>Etymology. From the Latin uni = one and lineatus = of a line, which refers to the mid-longitudinal black stripe on mesonotum.</p> <p>Remarks. Characters allowing a well-founded species-group placement are presently not available for M. unilineatus sp. nov. It appears to be related with M. trifidus Rafael &amp; Marques, 2019, described from Bolivia, as both species share the shape of tergite 8, distinct posterior inwardly setulose epandrial lobe, posterior cercus trifid, with each branch digitiform distally and hypandrium with a distal structure upwardly directed. It differs by the postcranium without dorsal pruinosity, sparsely gray pruinose on ventral half (versus entirely and sparsely gray pruinose in M. trifidus); scutum with mid-longitudinal black stripe from pronotum to posterior margin of mesonotum (versus scutum without black stripe); one postsutural supra-alar seta (versus 2 postsutural supra-alar setae); hind tibia with distal tuft of around 15 longer dorsal setae (versus 5 longer dorsal setae along entire length); tergite 8 with elongate projection notched medially (versus tergite 8 without notable notch); epandrium with short posterior lobe inwardly directed (versus epandrium with elongate posterior lobe inwardly directed); hypandrium with distinct membranous area, apex with an elongate, less sclerotized spoon-shaped upwardly directed appendix (versus hypandrium without membranous area, apex hooked). Female specimens differ by sternite 8 without ventral keel; sternite 8 without mid-longitudinal, less sclerotized stripe and lateral perpendicular area distinct, desclerotized (versus sternite 8 with distinct ventral keel, distinct desclerotized mid-longitudinal stripe from base to the middle of sternite and without lateral perpendicular desclerotized area in M. trifidus); genital fork wide with U-shaped mid-distal cleft (versus genital fork narrow); and genital chamber with two small sclerites (versus genital chamber without small sclerites).</p> </div>	http://treatment.plazi.org/id/03F5878CFFD2FFED75D1AE88C323ABE1	Public Domain	No known copyright restrictions apply.
