Armillipora suapiensis Ježek, Oboňa & Le Pont sp. nov.

( Figs. 21–38 )

Description. Male. Head ( Fig. 21 ) shortly oval in frontal view (1.2-times broader), flattened antero-posteriorly, vertex not elevated, rounded, occipital lobulus small (its height in comparison with the minimum width of frons is 1.3:1), with a conspicuous indentation apically, not sclerotized; corniculi not developed; insertions of supraocular bristles on dorsal margins of eye bridge are of the same size as those on vertex. Scars on vertex divided by a median, scar-free line. Eyes separated, with the narrowest upper part of frontoclypeus hardly as wide as facet diameter ( Fig. 29 ), eye bridge generally formed by 5 facet rows, however, reduced to 3–4 near frons. Dorsal parts of the eye approximately two-times as narrow as ventral apices. Ratio of the distance between the eye apices (tangential points) to the minimum width of the frons approximately 17.0:1. Interocular frontal suture sclerotized ( Figs. 21 , 29 ), Y-shaped and without a parallel ligament. Frontoclypeus ( Fig. 1 ) with two vertical, quite separated oblong alveoli patches prolonged vertically and inconspicuously expanded in the upper part, near the middle axis of the head; in the lower part they are a little expanded laterally on both sides. Antennae ( Figs. 30, 31 ) with 16 articles covered with many long setae, often as long as a single antennomere: scape bowl-shaped, narrower at the base and widened distally; pedicel similar to a compressed ball, 1.3-times as wide as high, scales shorter than its length. Basal flagellomeres pitcher-shaped, symmetrical, with necks two-times shorter than swollen basal parts as well as apical flagellomeres which are spindle-shaped, terminal flagellomere with a long digit, 2.1-times shorter than basal part. Sensory filaments (ascoids) simple, paired and needle-shaped ( Fig. 30 ). Maxilla and maxillary palpus ( Fig. 32 ): relative length ratios of palp segments 1.0:1.5:1.4:1.8, last segment not annulated. Maxilla covered with many setae and scales often 1.3-times as long as the basal palp segment; mouthparts extend beyond both ends of basal segments of maxillary palps ( Fig. 21 ). Terminal lobes of the labium, as shown in Fig. 22 , with conspicuous pointed trowelshaped teeth apically on both sides. Lines of spines between lobes not developed. Relative ratio of maximum length of cibarium to the length of labrum approximately 1.6:1 ( Figs. 21, 23 ).

Thorax: Anepisternum setae patch composed of a semicircular twice as large anterior part and a separated almost triangular posterior one, anepimeron with smaller prolonged and bent sickle setae patch, tapering posteriorly. Spiracles set low on mesothorax. There are no thoracic allurement organs. Wings ( Fig. 35 ) broadly lanceolate, 2.8 mm long – holotype, paratypes 2.1–2.8 mm, pointed distally at the ending of R 5 , somewhat expanded at the posterior margin, with a maculated, dark and conspicuous wing membrane. The large area around the basal cell is without infuscation (including the upper prolonged triangular arm); dark maculation is limited by end of Sc and start of R 1 , as well as the base of CuA 2. Gradually reduced-size white patches (almost spherical or hemispherical) always near the ending of veins below M 3 - R 5 as well as near end of R 4 - R 1 ; the last patch penetrates into the field between R 2 and R 3 . Additional doubled white patches near radial fork and in the hind wing margin ( Fig. 35 ). Following veins or their parts strengthened: distal two-thirds of R 1 , R 2 (basal part of R 2 +3 reduced), partially the basal cell, R 5 , CuA 1 and CuA 2. Radial and medial forks complete. Wing indices AB: AC:AD = 6.7:6.5:6.2; BC:CD:BD = 1.0:2.2:3.2. Wing index 2.4; medial wing angle 167°. Halteres ( Fig. 34 ) sack-shaped, asymmetrical in the vertical axis and with an inconspicuous stem. Ratio of maximum length of halteres to their maximum width of approximately 2.6:1. Ratios of lengths of femora, tibiae and first tarsal segments P 1 - 1.7:2.0:1.0, P 2 - 1.9:2.4:1.2, P 3 - 2.1:2.7:1.1. Fore claws bent, inconspicuously swollen distally and rapidly pointed at the end ( Fig. 24 ) .

Male terminalia. Aedeagal complex dredger-shaped and symmetrical; ejaculatory apodeme proximally remainders as a prolonged scoop with a circular aperture basally and a sclerotized median rib in the vertical axis ( Figs. 37, 38 ). Remainders of parameres and gonocoxites fused in a swollen bag; only divergent sickle-shaped gonostyli are free ( Figs. 37, 38 ), with a distinct lateral tooth in dorsal view, haired. Gonocoxal condyles ( Fig. 38 ) penetrate a concavity near basiphallus. Epandrium almost square-shaped, narrowed basally, with few linear setae on both sides of the central aperture, which is elliptical and not conspicuously sclerotized ( Figs. 25 , 36 ). Epandrial plate in the form of two gradually tapering strings to the sclerotized tip ( Fig. 25 ). Hypandrium on both sides narrow and sclerotized; however, probably membranous in the middle, though this was not detected. Hypoproct elongated and tongueshaped; epiproct only an inconspicuous fold, and both parts haired ( Figs. 25 , 36 ). Epandrial clasping lobes ( Figs. 25, 26 , 36 ) almost hemispherical, haired, prolonged and tapering distally with spoon-shaped hairless protuberances. Tenacula in two quite different shapes: cylindrical ( Figs. 25, 26, 27 , 36 ) with a folded terminal part placed almost in a line and a very long accessory (longer than epandrium) with lancet-shaped tips ( Figs. 25, 28 , 36 ), located on a slightly expanded single top of the ventral protuberance of clasping lobe.

Female: unknown.

Diagnosis. Head 1.2-times broader in horizontal axis in comparison with vertical axis. Eye bridge generally formed by five facet rows. The interocular frontal suture is without a parallel ligament. Medial wing angle 167° ( Fig. 35 ). Wings ( Fig. 35 ): basal third of CuA 2 not strengthened and intersects a dark patch. Aedeagal complex dredgershaped, ejaculatory apodeme proximally recalls a prolonged scoop with a circular aperture basally and a sclerotized median rib in the vertical axis ( Figs. 37, 38 ). Remainders of parameres and gonocoxites fused in a swollen bag; only the divergent sickle-shaped gonostyli are free ( Figs. 37, 38 ), with distinct lateral tooth in dorsal view, haired. Cylindrical tenacula of clasping lobes ( Figs. 25, 26, 27 , 36 ) are placed almost in one line.

Slide with a dissected specimen, Cat. No. 34869, Inv. No. 25561 ( NMPC) . Paratypes: 8 ♂, the same data as holotype, several specimens dissected, Cat. No. 34870–34875, Inv. No. 25562–25569 ( NMPC) , 1 ♂, the same data as holotype ( CBF) ; 1 ♂, the same data as holotype ( MNHN) .

Type locality. Foothills of La Paz, sub-Andean forest, Suapi , gloomy and very humid station .

Etymology. The species is named after the type locality.

Bionomics. Unknown.

Distribution. Bolivia.

Remarks. A. suapiensis sp. nov. differs from the other one known Armillipora species mainly in the shape of the terminalia, aedeagal complex, ejaculatory apodeme, epandrium and epandrial clasping lobes.
