Abstract
Re-examination of type specimens of LibiocorisKormilev 1957, L.poecilus from New Guinea and other taxa assigned to this genus, the Chinese Libiocorisheissi Bai, Yang & Cai, 2006 and Libiocorissinensis Bai, Yang & Cai, 2006 proved to be synonyms, thus L.heissi = L.sinensis syn. n. They are, however, different from Libiocoris Kormilev, 1957 to which they were originally assigned and a new genus Paralibiocorisgen. n. is proposed for them. Therefore Paralibiocorisheissi comb. n. = Libiocorisheissi Bai et al., 2006 = Libiocorissinensis Bai et al., 2006, syn. n. From Hainan Island, China, the following new species, P.roundangulussp. n., P.hainanensissp. n., and P.limuensissp. n., are described and figured and a key to species is provided.
Highlights
The genus Libiocoris was erected by Kormilev, 1957 for the species poecilus from New Guinea
Usinger & Matsuda, 1959 improved the generic description based on the new species L. antennatus from Papua (New Guinea) and added L. angulatus, from New Guinea to this genus
General aspect similar to Paralibiocoris heissi, but distinguished from it by a wider pronotum, 2.86 times as wide as long (2.80 in P. heissi), anterolateral lobes
Summary
The genus Libiocoris was erected by Kormilev, 1957 for the species poecilus from New Guinea. Head as long as wide across eyes; median plate of meso- metanotum more elongate 1.82 times as long as wide (0.73/0.40); mtg VII strongly elevated posteriorly; reflexed vltg VII forming triangular lobes posterolaterally, ventral side with a distinct oblique smooth callus, reaching lateral margin; ptg VIII short and clavate much shorter than cordate pyriform pygophore (Figs 13, 14); parameres slender (Figs 15–17).
