Genus: Onorecoris
Name
Onorecoris piceus Heiss, 2013 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Holotype female
labelled: Ecuador, Loja 7 Uritujinga 2800m / 19 Dec. 1997 G.Onore. CEHI. The specimen is damaged by a pinhole on the abdomen and lacks the right antennal segments II-IV. It was cleaned and remounted by the author. This specimen is designated as holotype and labelled accordingly.
Description
Medium-sized apterous Carventinae, body broadly ovate, attenuated anteriorly; surface rather flat with rugosities and punctures; colouration piceous.
Head. Longer than wide (23/22.5, incl. neck 25/22.5); clypeus narrow, raised with a round tubercle subapically; genae thin, produced over apex of clypeus reaching about ½ of antennal segment I, antenniferous lobes diverging laterally, apex with a round tubercle; antennae 2.09× as long as width of head (47/22.5), segment I thickened on anterior ¾ densely beset with tubercles bearing stiff hairs, II shortest, III longest, IV fusiform with pilose apex; length of antennal segments I/II/III/IV = 12.5/8/18/8.5; eyes slightly stalked; postocular lobes uniformly converging to constricted neck; vertex with a median ridge, this posterolaterally with 2 (1+1) elevated round tubercles, separated from lateral oval callosities by deep grooves.
Pronotum. Strongly transverse, more than 3× as wide as long (35/11); lateral margins angularly produced on humeri then triangularly projecting anteriorly, longer than collar; disk with a V-shaped median sclerite anteriorly followed posteriorly by small median triangular ridge separated from oval callosities by deep grooves; posterior margin convex, transverse suture separates the mesonotum.
Mesonotum. Distinctly wider than long (45/10), consisting of a median posteriorly widening and moderately elevated pentagonal ridge and lateral subrectangular sclerites with rugose surface, their lateral margins rounded, produced laterally; separated from metanotum along lateral sclerites by deep grooves, median ridge fused, continuing on metanotum and mtg I+II where its structure is obliterated.
Metanotum. About 3.5× as wide as length including fused mtg I+II (52/15); lateral sclerites separated from continuous median ridge by deep depressions, their surface deeply punctured and callous, posteriorly completely fused to mtg I+II; lateral margins with a small round expansion.
Abdomen. Lateral and anterior margins of tergal plate convex, posterior margin straight; its surface rather flat with moderately rounded elevation on mtg IV-V, highest at scent gland scar IV-V; lateral parts with oval punctured depressions on mtg IV-VI, those of mtg III larger, directed anteriorly, their lateral margins delimited by carinae, these enlarged on anterolateral angles; deltg II-VII separated by sutures, triangular deltg II anteriorly reaching metanotum; pe-angles of deltg II-VII slightly reflexed, rounded, with larger dorsal, granulate tubercle; dorsally reflexed margins of vltg II-VII partly visible from above as lateral rims which increase in size from deltg II-VI forming triangular tubercle on deltg VII; tergite VII with a median elevated ridge, tergite VIII bilobate, visible apices of tergites IX and X tricuspidate, as long as posteriorly produced paratergites VIII.
Venter. Spiracles II-IV ventral, V sublateral and visible from above, VI and VII on sublateral tubercles of reflexed vltg VI and VII and visible from above, VIII dorsolateral¸sternites separated by transverse sutures, surface rugose and punctured,
Legs. Long and slender, femora cylindrical, tibiae medially curved, tarsi bisegmented, claws with thin pulvilli.
Measurements. Length 6.1mm; width of abdomen across tergite III and IV 3.65mm, V 3.5mm; width of tergite VIII 1.05mm; width /length of tergal plate 2.3/2.1mm; length of antennae 2.35mm.
Etymology
The epithet refers to the piceous colouration of this unusual specimen.
