Sanaungulus perkovskyi sp. nov.
( Fig. 19 View Fig )
Holotype. Male, adult specimen in a Burmese (Kachin) amber piece: Catalog number SNSBBSPG 2021 XII 69 in the Bayerische Staatssammlung für Paläontologie und Geologie (ex Müller’s collection number: BUB3888 ).
Type locality. Myanmar: Kachin state, Myitkyina District, Hukawng Valley.
Type horizon. Lowermost Cenomanian (98.79 ± 0.62 Ma), midCretaceous.
Differential diagnosis. Sanaungulus perkovskyi sp. nov. is characterized by a strongly transverse pronotum and pectinate antennae (the antennal process in antennomeres IV–VII). Sanaungulus ghitaenoerbyae Fanti, Damgaard & Ellenberger, 2018 is the most similar taxon and differs from the new species because of its more transverse head and its pronotum with its sides and posterior margin not straight (Fanti et al. 2018). Sanaungulus troelsikloevedali Fanti & Damgaard, 2019 differs from the new species described here by its longer antennae with more slender last antennomeres ( Fanti & Damgaard 2019).
Description. Adult, winged, rather robust. Male, defined on the basis of the last abdominal segment triangular shaped. Body length 3.2 mm. Entirely testaceousbrown.
Head not particularly transverse, constricted (triangularshaped) behind the eyes, pubescent with shallow punctation. Eyes prominent, large, roundish, inserted in the upper and lateral part of the head. Mandibles elongated, falciform. Maxillary palps 4 segmented with the last palpomere securiform. Labial palps 3 segmented, with the last palpomere securiform. Antennae 11 segmented, pectinate, approximately slightly surpassing the half of elytra, antennal insertion far from the eyes; scape clubshaped, robust; antennomeres II–III short with antennomere II sturdier and swollen apically; antennomeres IV– VI extremely long, each equipped with an antennal process at apex which is very long and robust and slightly pointed apically; antennomere VII shorter than previous ones, equipped with a long antennal process; antennomere VIII sturdier and shorter than previous one and without the antennal process; antennomeres IX–X very robust, flat, enlarged at sides; antennomere XI filiform, less sturdier than previous ones, with rounded apex; all the antennomeres pubescent with setae very short.Pronotum transverse, wider than head, anterior margin undulate and strongly bordered, posterior margin straight and bordered, sides straight and bordered, corners obtuse, pronotum disc pubescent with shallow punctation. Scutellum triangularshaped, very wide at base, with rounded apex. Elytra short which reveals some abdominal segments, robust, wider than pronotum, posteriorly parallelsided and not dehiscent apically, rounded apexes, surface with coarse and impressed punctation gathered in striae. Metathoracic wings transparent, longer than elytra. Sternum elongated with posterior margin almost straight, sternites transverse and pubescent, last sternite small and triangular shaped. Legs thin, long, slightly pubescent; coxae massive; trochanters small, rounded; femora almost straight, slightly flat, sturdier than tibiae; tibiae, thin, cylindrical, long, without spurs near the apex, pro and mesotibiae very slightly longer than pro and mesofemora, metatibiae longer than metafemora. Tarsal formula 5 5 5; first tarsomere long, about 1.4 times longer than second; third tarsomere short, triangularshaped; fourth strongly bilobed with lobes elongated and rounded apically; fifth tarsomere elongated, thin, cylindrical and curved; claws simple, long, pointed, without denticle at the base.
Etymology. Named in honor of Evgeny E. Perkovsky ( Ukraine), a wellknown palaeontologist.
Syninclusions. Air bubbles (very large), detritus.
Remarks. Piece of very clear amber that measures 12x8x 2 mm. The inclusion is complete, but many big bubbles in the amber cover the majority of its ventral part.
