Type material. Holotype male. Deia , town fountain, 39.748072°N , 2.643385°E , 8.ii.2015, G.Kvifte, M. Stokkan & C. Garcia leg (ZMUB). Diagnosis. Pericoma unipennata can be separated from all other Pericoma species on the presence of one feather-tipped and four spatulate tenacula on each surstylus, as well as the following combination of characters: parameral sheath with shallow U-sha ped apical indentation 1/6th as deep as width of parameral appendage base, gonostyle with narrow distal part 1/4th as long as broad basal part, distiphallic spatula with sclerotized side margins not converging apically, parameral appendage concave at lateral sides with distal 1/8th protruding over distiphallic spatula. Description. Male (n=1). Head (Fig. 1A) longer than wide; vertex rounded with posterior lobe pointed, about half length of head; eyebridge comprising four rows of facets, separated by five facet diameters; interocular suture broadly V-shaped with median swelling; 7 supraocular setae present, 3 on ventral side and 4 on dorsal side; frontal scar patch inversely T-shaped, reaching level of uppermost facet row of eyebridge; clypeus subrectangular, weakly concave at anterior margin, densely setose, not protruding in front of level of eyes; palp with 4th segment fleshy, corrugated, length of palpus segments 93: 106: 129: 231; labellum fleshy, micropilose with 11 larger setae; antennae with 14 fusiform flagellomeres; scape cylindrical, pedicel elongate globular to barrell-shaped; ascoids present on flagellomeres 4-8; flagellomere 14 with apiculus about as long as base of segment; length of antennal segments 69: 63: 48: 45: 45: 42: 42: 42: 42: 42: 36: 36: 33: 27: 24: 36. Figure 1. Pericoma unipennata sp. n., holotype male. A Head B Wing C Aedeagus D Male genitalia E Tenacula. The following abbreviations are used: bp - basiphallus, c r - cercal region, dp lm - distiphallic lateral margin, dp s - distiphallic spatula, f t - feathery tenacula, gcx - gonocoxite, gst - gonostyle, hyp - hypandrium, pm - parameral sclerite, pm j - parameral joint, pms - parameral sheath, s t - spatuliform tenacula. Thorax without accessory organs; mesonotum and scutellum covered in setae alveoli except on lateral margins; anepisternum and laterotergite covered with setae alveoli; coxae and trochanters with dorsal and ventral stripes of setae alveoli, mid coxa with apicoanterior setose projection; legs without special features; Wing (Fig. 1B) 2.3 mm long, subovate, membrane without setation or infuscation; radial fork very slightly distad of medial fork, both slightly distad of CuA2; C with two breaks; Sc weakly curved towards C; apical section of R2 curved anteriorly; wing apex between R4 and R5; medial fork incomplete; apical section of CuA2 curved posteriorly; jugum obtuse; Genitalia (Fig. 1C, D) with hypandrium of even width; aedeagus (Fig. 1D) with basiphallus compressed laterally; distiphallus consisting of two phallomeres forming a spatula with sclerotized lateral margins, lateral margins not converging distally; parameral sheath fused with gonocoxites basally, distally narrowing to nearly half its width at base; distally with narrow median incision; parameral sclerite meeting distal section of basiphallus, jointed to parameral sheath with slightly curved transverse band-like sclerite; parameral sclerite half length of distiphallus, consisting of two fused sclerites which are concave laterally, median suture complete; gonocoxites (Fig. 1C) stout, reniform, parabasal process absent but setose field present near connection with parameral sheath; gonocoxal condyles apparently fused with parameral sheath, gonostyle (Fig. 1C) with basal four 5ths liver-shaped, stout, distal 5th pointed, weakly sinous; epandrium slightly wider than long, expanding distally, number of apertures not discernable in specimen, carrying sparse hairs on ventral surface; surstyli about as long as epandrium, with lateral inner third more weakly sclerotized and densely micropilose; apex of surstylus with five aseriate tenacula of which one apical is feathery at the apex, four subapical tenacula spatulate; hypoproct obtusely isosceles trapezoid, micropilose; epiproct oval, densely pilose. Etymology. unipennata = with one feather; refers to the presence of a single feather-tipped and four spatulate tenacula on its surstyli. Biology. The specimen was collected at a spring with many bryophytes growing in a seepage stream. Bryophyte material was collected and extracted, however, no psychodid larvae or pupae were found.
