Differential diagnosis
Armillipora imitata sp. nov. is very similar to A. muyu sp. nov. and A. selvica but the three can be differentiated as follows: in A. selvica the interocular suture has a short posterior spur (posterior spur absent in A. imitata and in A. muyu); one conical apical and one spiniform tooth at the apex of labella in A. imitata (only one conical apical teeth in A. selvica; one preapical spiniform and one apical clawshaped in A. muyu); A. imitata has six apical setae at the apex of gonocoxites (three to four setae placed on a preapical lump in A. muyu, and three to four preapical setae in A. selvica); the gonocoxal condyles is not triangular and not protruding beyond the base of the ejaculatory apodeme in A. imitata and A. muyu (the sclerite is triangular and protruding beyond the base of ejaculatory apodeme in A. selvica).
Etymology
The species epithet ‘ imitata ’ derives from the Latin word ‘ imitātus ’ (feminine ‘ imitāta ’) referring to its similarity with other species. It is to be treated as an adjective.

Description
MEASUREMENTS in mm (n = 3). Wing length: 2.19 (2.20–2.18), width: 1.00 (1.05–0.98). Head length: 0.50 (0.52–0.48), width: 0.55 (0.56–0.52). Antennal segments: scape: 0.10 (0.10–0.10); pedicel: 0.06 (0.06–0.06); flagellomeres 1–5: 0.15 (0.15–0.11), flagellomeres 6–10: 0.12 (0.15–0.13). Palpal segment 1: 0.07 (0.07–0.07); palpal segment 2: 0.08 (0.09–0.08); palpal segment 3: 0.08 (0.08–0.08); palpal segment 4: 0.14 (0.15–0.14).
Male
HEAD. About 1.10 times as wide as long; eye bridge separated by l facet’s diameter, with four rows of facets, interocular suture as sclerotized, almost straight line; frontal patch of alveoli divided. Antennal scape about 1.5 times as long as pedicel, almost cylindrical; pedicel spherical, smaller than scape; flagellomeres fusiform and longer than scape, with scattered setae on surface, setae almost as long as flagellomere bearing them, each flagellomere with two rings of teardrop-shaped pores, apical flagellomeres absent in examined material, maximum number of flagellomeres present: five; ascoids indistinguishable in examined material. Palpal segments cylindrical, palpal proportions: 1.0:1.1:1.1:1.8, last palpal segment corrugated; labium without any strong sclerite; labella elongated and irregularly shaped scattered setae on surface, with one apical spiniform tooth on each.
THORAX. Without allurement organs. With single patch of alveoli in paraterguite and antepronotum; all coxae with stripe of one to two rows of alveoli. Wing length about two times its width; wing membrane brown-infuscated, with lightened spots in between apex of longitudinal veins, and with light triangular-shaped spot between origin of R 1 and R 2+3 (Fig. 1B); subcostal vein short ending beyond origin of R 5; junction of R 2+3 basal to junction of M 1+2, not joining R 4, origin of M 1+2 basal to origin of R 2+3; R 5 ending at wing apex; CuA
2 faintly ending at wing margin.
TERMINALIA (Figs 1C–D, 2B–E). Hypandrium in dorsal view V-shaped, sclerotized and joining base of gonocoxites, in lateral view hypandrium looks membranous (Figs 1C, 2B, E) with sclerotized margin; gonocoxites joining at apex forming U-shaped sclerite, with concavity at lower margin. Gonocoxite sclerite placed above aedeagal complex. On each side of sclerite is a preapical cluster of six setae (Figs 1C, 2B); gonostyli absent; aedeagus in dorsal view straight, as single sclerite, no discernible parameres. In lateral view, aedeagus apex curved towards epandrial appendage (Figs 1D, 2E); ejaculatory apodeme about half length of aedeagus, in dorsal view basal margin rounded and slightly concave in middle, in lateral view, ejaculatory apodeme looks like half-circle, with basal margin convex; gonocoxal condyles fitting in concavity on underside of ejaculatory apodeme, not triangular-shaped and not protruding beyond base of ejaculatory apodeme; epandrium rectangular, wider than long, with more sclerotization at margins, anterior and posterior margins with medial concavity; hypoproct tongue-shaped (Fig. 1C), shorter than epandrium and covered with small setulae, epiproct not visible in examined material; epandrial appendage barely hemispherical, prolonged and tapering distally, covered with small setae; epandrial appendage lacking apical tenacula. In dorsal view (Figs 1C, 2B), line of five short and cylindrical tenacula, with folded tips; in lateral view, (Figs 1D, 2E) first four tenacula close to each other, last tenaculum separated and located in projection of epandrial appendage, this projection not visible in dorsal view; epandrial appendage possesses additional patch of long accessory tenacula basally concentrated in darkened patch, these accessory tenacula being as long as or longer than epandrium (Figs 1C, 2B).
Female
Unknown.
Distribution
Only known from the type locality in Ecuador.
Genetics
Three specimens were successfully sequenced (ZFMK-TIS-2637091, ZFMK-TIS-2637173, and ZFMK-TIS-00097931). The maximum intraspecific uncorrected pairwise distance for COI sequences was 1.06 % or 7 bp. GenBank accession numbers are: OQ706375; OQ706387; OQ706388.
