Apotropina longicerci sp. nov.

( Figs 1–8 View FIGURES 1–8 , 25–26 View FIGURES 25–26. 25 )

Diagnosis. Postpedicel brown on upper ¾, yellow on lower ¼ in external surface ( Fig. 1 View FIGURES 1–8 ); fore coxa dark yellow, darker posteriorly ( Fig. 1 View FIGURES 1–8 ); all legs with basal apex of femur and tibia yellow, tibial organ narrow, yellow, ~ 3× shorter than hind tibial length, hind tibial spur indistinct ( Fig. 1 View FIGURES 1–8 ); surstylus widened in profile ( Fig. 5 View FIGURES 1–8 ); male cercus more than 2× longer than wide, with a curved seta longer than surstylus length ( Figs 7–8 View FIGURES 1–8 ).

Description. MALE (holotype). Body length 3.4 mm. Wing length 4 mm. Body dark brown with ochre pruinosity. Head ( Figs 1–2 View FIGURES 1–8 ). Wider than long dorsally and longer than high in profile. Ocellar seta as long as inner and outer vertical setae. Postocellar seta cruciate, ~ ⅔ the length of ocellar seta. Three strong fronto-orbital setae, the anterior seta ~ ½ the length of the posterior setae, the two posterior setae ~ each equal to length of the ocellar seta; the anterior fronto-orbital seta proclinate, the two posterior fronto-orbital setae lateroclinate. Inner vertical seta proclinate, outer vertical seta lateroclinate. Frons dark brown basally, apical ¼ yellow, slightly wider than long, lateral margins diverging posteriorly to ocellar triangle, apical margin sinuous. Ocellar triangle extending to ~ ⅔ length of frons, posterior margin nearly as wide as frons, lateral margins straight, apex acute. Eye oval, long axis slightly oblique. Face pale yellow, about as high as wide; postpedicel rounded, brown on upper ¾, yellow on lower ¼ in external surface; arista dark brown, with short, sparse pubescence, as long as ½ frons; genal height equal to height of postpedicel, with whitish pruinosity; one vibrissa; occiput and postgena dark brown; proboscis brown; palpus yellow with black setulae; clypeus darkened. Thorax ( Figs 1, 3 View FIGURES 1–8 ). Scutum dark brown, ~ 1.2× longer than wide, pruinose; postpronotal lobe concolorous with scutum, with two long setae equal in length to notopleural setae; 1+1 notopleural setae; 5 strong dorsocentral setae, prescutellar dorsocentral seta ~ 2× longer than remaining dorsocentral setae; pleuron with grey pruinosity; katepisternun with pale setulae. Scutellum concolorous with scutum, with black pilosity, apical scutellar seta ~ 3× longer than subapical scutellar seta. Halter stem brown, knob pale yellow. Wing ( Fig. 4 View FIGURES 1–8 ). Brown infuscate; costal ratios measured from h: R 1: R 2+3: R 4+5 is 4: 5: 3.5: 1.8; veins R 4+5 and M 1 subparallel; distance between r-m and dm-m 4.5× length of r-m. Legs ( Fig. 1 View FIGURES 1–8 ). Dark brown; fore coxa dark yellow, darker posteriorly; fore and mid trochanters yellow; all legs with anterior apex of femur, tibia and first tarsomere yellow; tibial organ narrow, yellow, ~ 3× shorter than hind tibia length ( Fig. 1 View FIGURES 1–8 ); hind tibial spur indistinct. Abdomen ( Fig. 1 View FIGURES 1–8 ). Tergites dark brown. Terminalia ( Figs 5–8 View FIGURES 1–8 ). Postabdominal sclerites asymmetric; syntergosternite 7+8 about as long as hypandrium; sternite 6 curved, as wide as sternite 5, with a lobe on inner margin medially; sternite 5 curved, wider medially, tapering to extremes, ~ 5× longer than wide. Epandrium brown, fusiform in profile, with brown pilosity, without laterobasal projection; subepandrial sclerite V-shaped, base narrower than cerci; surstylus with apical half yellow and with short, yellow setae, base slightly narrower than epandrial in profile, apex broad and round; cercus at least 2× longer than wide, with curved setae ~ 1.5× as long as surstylus, cerci basally fused; anal lobe indistinct. Hypandrium with arms closed; basiphallus slightly oval, as long as distiphallus; distiphallus sclerotized ventrally; pre- and postgonite equal in length; sperm pump indistinct.

FEMALE. Unknown.

Type material. HOLOTYPE ♂, deposited in LEUA: COLOMBIA, Caquetá, Florencia , Vda.[Vereda] Sucre, 01º52′12″N / 75º40′09″W, 2292 m [eters], 26–28.Sep [IX].2023, Y. Ramos-Pastrana Leg. / Captura con trampa Malaise colocada a nivel de un sistema lótico (al aire) / ( LEUA-67440 ) GoogleMaps . PARATYPE: same data as holotype (1 ♂ LEUA-67441 ) GoogleMaps .

Etymology. The specific epithet refers to “Latin, longus, meaning long + cerci, referring to the genitalic structure; a noun in apposition; in reference to the long cerci in the male”.

Geographical occurrence. Colombia (Caquetá, Florencia) ( Fig. 25 View FIGURES 25–26. 25 ).

Habitat. The specimens were collected in a Malaise trap placed over a creek in the low montane rainforest with dense secondary vegetation in the Andean-Amazonian transition corridor of Colombia ( CAM 2018) ( Fig. 26 View FIGURES 25–26. 25 ).
