Genus Armillipora Quate

Armillipora Quate, 1996: 29 . Type species: Armillipora selvica Quate, 1996 (by orig. des.)

Redescription of males. Armillipora is characterized by the following characters: Head ( Figs. 1 , 21 ) in horizontal axis a little broader than in vertical axis, flattened antero-posteriorly, vertex rounded, occipital lobulus with an indentation apically. Corniculi not developed; insertions of supraocular bristles on dorsal margins of eyes not enlarged. Scars on vertex divided by a median, scar free band. Eyes separated, eye bridge formed by 4–5 facet rows, the number of facets in the apices being more reduced. The eye bridge is narrower than the ventral portion of the eye. Interocular frontal suture sclerotized ( Figs. 1 , 11 , 21 , 29 ), Y-shaped. Frontoclypeus ( Figs. 1 , 21 ) with two vertical, quite separated, approximately oblong, alveoli patches. Antennae ( Figs. 12 , 30, 31 ) with scape truncated, narrower at the base and widened distally, pedicel globular with scales very narrow and of different lengths. Flagellomeres pitcher-shaped, symmetrical, with necks shorter than swollen basal parts, with pores around each node, apiculus of the last flagellomere developed ( Fig. 31 ). Sensory filaments (ascoids) simple, paired and needle-shaped ( Figs. 12 , 30 ). Last segment of maxillary palpus not annulated ( Figs. 2 , 32 ). Terminal lobes of labium with apical pointed projection ( Figs. 3 , 22 ).

Thorax. Anepisternum setae patch composed of two quite separated groups (not mentioned by Quate), anepimeron setae patch divided, but not always so markedly ( Fig. 5 , 33 ). Metathoracic spiracles set low on mesothorax. There are no thoracic allurement organs. Wings ( Figs. 13 , 35 ) broadly lanceolate, pointed at the end of R 5, somewhat expanded at the posterior margin and characteristically maculated; three-quarters of wing membrane dark. Radial and medial fork complete, basal to the wing centre, positioned as seen in Figs. 13 , 35 . Medial wing angle 167–180°.

Male terminalia. Aedeagal complex symmetrical. Gonocoxal condyles ( Figs. 17 , 38 ) penetrate a concavity on the underside of basiphallus. Epandrium almost square-shaped, setae are very sporadic on both sides of the central aperture ( Figs. 8 , 14 , 25 , 36 ). Hypandrium on both sides narrow and sclerotized, however, membranous in the middle. Remainders of ventral epandrial plate in the form of two gradually tapering strings to the sclerotized tip. Epandrial clasping lobes ( Figs. 8 , 14 , 25, 26 , 36 ) approximately hemispherical, haired, prolonged and tapering distally with a spoon-shaped hairless protuberance and dorsally provided by two tubercles with quite different shapes of tenacula: cylindrical ( Figs. 8 , 14, 15 , 25, 26, 27 , 36 ) with a folded terminal part and a very long accessory type with lancet-shaped tips ( Figs. 8 , 14, 16 , 25, 28 , 36 ).

Differential diagnosis. Probably a neotropical genus of Maruinini Enderlein, 1937 (compare Duckhouse 1987, 1990, Quate 1996, Ibáñez-Bernal & Suárez-Landa 2015), by the presence of a wing with radial fork basal to medial one, and both placed rather basally on wing; by the shape of the basiphallus (ejaculatory apodeme), which is broad, dorso-ventrally flattened; and the gonocoxal condyles ( Figs. 17 , 38 ) fitting into a concavity on the underside of the basiphallus. Armillipora resembles, upon first view of a collector in nature, species of Alepia Enderlein, 1937 , and Platyplastinx Enderlein, 1937 , by its conspicuous wing maculation and less distinctly visible characters, such as the shape of two types of tenacula (short cylindrical with a folded tip and long accessory filaments with a lancetshaped ending). It clearly differs from genera of the former Setomimini of Quate & Brown (2004) by no detection of declined gonopods as well as the presence of parameres, both sometimes quite reduced or missing, with only a conspicuous, very long aedeagal complex. The tunica is not developed (compare to known species of Alepia ).
