Genus Metipocregyes Breuning, 1939

Metipocregyes Breuning, 1939: 429 .

Type species. Mesosa nodieri Pic, 1933

Redescription. Body 10.1–19.0 mm, moderate in size or relatively small among the genera of Mesosini . Eye subdivided into upper and lower lobes connected posteriorly by narrow line with/without single row of ommatidia, or deeply emarginate and the lobes connected posteriorly by 2–4 rows of ommatidia; lower lobe large, prominent, somewhat vertically long. Antennal tubercle gently elevated. Antenna moderately thick, fringed with suberect hairs beneath antennomeres, gradually sparser and shorter toward apical segment; antennomere I thick and short, subequal to or slightly shorter than antennomeres III and IV respectively, gently thickened apically, with cicatrix on apex of outer side; antennomere III slightly longer than IV. Pronotum transverse, gently swollen laterally, with/ without rudimentary projection anterolaterally, with pair of indistinct swellings on disk, weakly constricted and transversally depressed near base and apex. Prosternal process with slightly ridged lateral margins, rounded in lateral view. Mesosternal process with ridged lateral margins forming pair of small projections near apex, nearly truncate in lateral view. Elytron with long suberect hairs throughout, somewhat projected anteriorly beside scutellum, slightly raised longitudinally behind base; humerus subquadrate and slightly expanded laterally; apical margin arcuate with sub-quadrate inner angles. Mesotibia simple, without distal notch at outer margin.

Male genitalia with tegmen wide in dorsal view; paramere somewhat thick. Endophallus 2.5–4.0 times as long as median lobe, subdivided into BPH, MPH (delimited into MT+CT and PB), and APH, but APH almost fused and swollen together with distal part of PB. MPH with MT+CT long, about twice length of median lobe, bent at distal half, with MSp and LSp; PB elongate, cylindrical, with SSp. APH undeveloped, with single ED usually on dorsal side, sometimes with rudimental AA on distal part. MSp indistinct, mainly distributed in proximal 2/3 of MT+CT; LSp uni-dentate, small, distributed in distal 1/5–1/3 of MT+CT; SSp unidentate, minute, covered most area of PB and proximal area of APH.

Remarks. The genus Metipocregyes had been defined mainly by the following features since its establishment (modified Breuning, 1939): Body elongate. Eye subdivided; lower lobe slightly longer than wide. Antennal tubercle slightly elevated. Antenna robust, scarcely longer than body, fringed with long hairs; antennomere I long, with developed cicatrix; antennomere III distinctly longer than I and IV. Pronotum transverse, with slightly distinct transverse furrow. Elytra long, rounded apically, roundly projected forward at middle of each base. Prosternal process weakly projected below, rounded in lateral view. Mesosternal process with tubercle at middle, truncate at anterior margin. Legs short and thick; mesotibia without distal notch.
