Armillipora selvica Quate

( Figs. 1–20 )

Armillipora selvica Quate, 1996: 29 ; Quate 1999: 427 (geographical record).

Redescription of male. Head ( Fig. 1 ) barely circular from the frontal view (1.4-times broader), flattened anteroposteriorly, vertex rounded, not elevated; occipital lobulus small (its height and minimum width of frons represent the same proportion), with a shallow indentation apically and sclerotized on both sides; corniculi not developed; insertions of supraocular bristles on dorsal margins of eyes not enlarged. Scars on vertex divided by a median, scarfree band. Eyes separated, with the narrowest upper part of frontoclypeus approximately as wide as facet diameter ( Fig. 11 ), eye bridge formed by 4 facet rows, number of facets in the apices being more reduced. Dorsal parts of the eye section 1.8-times as narrow as ventral apices. The ratio of the distance between the eye apices (tangential points) to the minimum width of the frons is approximately 14.3:1. The interocular frontal suture is sclerotized ( Figs. 1 , 11 ) and Y-shaped, doubled by a parallel ligament, slightly convex and barely transparent. The frontoclypeus ( Fig. 1 ) has two vertical, quite separated, oblong alveoli patches (a little prolonged vertically, not laterally expanded). Antennae incomplete ( Fig. 12 ), scape truncated, narrower at the base and widened distally, pedicel globular, with 1.2-times reduced size in comparison with the maximum width of scape, scales very narrow, approximately as long as pedicel. Flagellomeres 1–2 pitcher-shaped, symmetrical, necks shorter than swollen basal parts, each node with a doubled circle of teardrop-shaped pores near the centre (Quate´s term), however, not always detected exactly. The sensory filaments (ascoids) are simple, paired and needle-shaped ( Fig. 12 ). Maxilla and palpus maxillaris ( Fig. 2 ): relative length ratios of palp segments 1.0:1.0:1.0:1.7, last segment not annulated. Maxilla is 1.1-times as long as basal palp segment, mouthparts extend beyond both ends of basal segments of maxillary palps ( Fig. 1 ). Terminal lobes of the labium, as shown in Fig. 3 , with conspicuous teeth pointed apically on both sides. The lines of the spines between lobes are not developed. Relative ratio of maximum length of cibarium to the length of labrum approximately 1.5:1 ( Figs. 1, 4 ).

Thorax: Anepisternum setae patch composed of semicircular two-times larger anterior swollen part and a separated, almost oval posterior one; anepimeron with a smaller prolonged setae patch, tapering posteriorly and inconspicuously interrupted in the middle. Spiracles set low on mesothorax. There are no thoracic allurement organs. Wings ( Fig. 13 ) broadly lanceolate, 2.4–2.9 mm long, pointed distally at the ending of R 5, somewhat expanded at the posterior margin, maculated, with the wing membrane dark and conspicuous. Infuscation on free parts of wing: a large area around the basal cell (also see the upper prolonged triangular arm) limited by the ending of Sc and start of R 1, as well as a third swollen part of CuA 2. White, gradually reduced-size patches (almost hemispherical, always between the endings of veins) towards the tip of wing limited by the end of R 1 and the ending of CuA 2, here with an overlap of CuA 1 in the middle. Additionally, connected longitudinal white patches limited by radial fork and C, and the connected white patch approximately P-shaped between CuA 1 and hind wing margin, with a narrow white stripe along it. Following veins or their parts are strengthened: R 1, R 2 (basal part of R 2+3 missing), basal cell, R 5, CuA 1 and CuA 2 (more strengthened basally). Radial and medial fork complete, positioned as seen in Fig. 13 . Wing indices AB:AC:AD = 4.7:4.5:4.5; BC:CD:BD = 1.0:1.7:2.7. Wing index 2.4, medial wing angle 180°. Halteres ( Fig. 6 ) elongated ovoid with a prolonged stem. Ratio of maximum length of halteres to their maximum width of approximately 3.9:1. Ratios of lengths of femora, tibiae and first tarsal segments are P 1 - 1.5:1.8:1.0, P 2 - 1.6:2.0:1.1, P 3 - 1.7:2.3:1.0. Paired tarsal claws of P 1 conspicuously bent distad ( Fig. 7 ).

Male genitalia. Aedeagal complex arrow-headed, clearly symmetrical, ejaculatory apodeme proximally in three connected mutual layers: a large broadly triangular layer, bilobed and cornered on both sides ( Fig. 18 ); a smaller almost circular layer ( Fig. 10 , 18 ); and a small inner oval layer with a concave cleft proximally ( Figs. 19, 20 ). Remainders of parameres and gonopods fused and adhered to distiphallus ( Figs. 9 , 17, 18 ). Gonocoxites are cut at right angles with three-four setae subapically ( Figs. 9 , 17, 18 ). Gonocoxal condyles ( Fig. 17 ) fit into a concavity on the underside of basiphallus. Epandrium almost square-shaped, a little widened basally, and with very sporadic setae on both sides of the conspicuous central aperture, which is barely elliptical, sclerotized laterally and proximally convex ( Figs. 8 , 14 ). Remainders of epandrial plate in the form of two gradually tapering strings to the sclerotized tip. Hypandrium on both sides narrow and sclerotized, however, membranous in the middle. Hypoproct tongue-shaped, epiproct only as a fold, both parts haired ( Figs. 8 , 14 ). Epandrial clasping lobes ( Figs. 8 , 14 ) barely hemispherical, haired, prolonged and tapering distally with spoon-shaped hairless protuberances and dorsally with two tubercles with quite different shapes. Tenacula cylindrical ( Figs. 8 , 14, 15 ) with a folded terminal part and a very long accessory (as long as or a little longer than epandrium) with lancet-shaped tips ( Figs. 8 , 14, 16 ). The basal group of cylindrical tenaculi (dorsal view – Fig. 8 ) is similar to a moon knife.

Female: Briefly described by Quate (1996).

Diagnosis. Head 1.4-times broader in the horizontal axis in comparison with the vertical axis ( Fig. 1 ). Eye bridge formed by four facet rows, interocular frontal suture sclerotized ( Figs. 1 , 11 ), Y-shaped and doubled by a parallel ligament. Wings ( Fig. 13 ): basal third of CuA 2 strengthened and without contact with a dark patch. Medial wing angle 180°. Aedeagal complex arrow-headed, ejaculatory apodeme proximally in three connected mutual layers: a large broadly triangular layer, bilobed and cornered on both sides ( Fig. 18 ); a smaller almost circular layer ( Fig. 10 , 18 ); and a small inner oval layer with a concave cleft proximally ( Figs. 19, 20 ). Remainders of parameres and gonopods fused and adhered with distiphallus ( Figs. 9 , 17, 18 ). Gonocoxites are cut at a right angle with threefour setae subapically ( Figs. 9 , 17, 18 ). Basal group of cylindrical tenaculi of clasping lobes (dorsal view – Fig. 8 ) is similar to a moon knife.
