Globicornis (Socotracornis), HávA, 2013

HávA, Jiří, 2013, Contribution to the knowledge of the Globicornis Latreille, 1829 species (Coleoptera ¡ Dermestidae ¡ Megatominae) from Socotra Island (Yemen)., Arquivos Entomolóxicos 9, pp. 73-76 : 74-75

Subgenus Socotracornis subgen. nov.

Type species: Globicornis (Socotracornis) fallax sp. nov. (by monotypy).

Description.

Body very small, oval TL 1.6-1.9 EW 0.8-1.1 ( Fig. 1 ), head and pronotum unicolorous, elytral cuticle black with brownish-orange fasciae covered by whitish recumbent very narrow scales with intermixed erect, black setation, ventral surfaces covered by whitish setation. Antennae brown with white setae, consisting of 10 antennomeres, terminal antennomere flat and large ( Fig. 2 ). Male genitalia as in Fig. 3 .

Differential diagnosis. The new subgenus belongs to the “genera group I” ( Háva 2004) and is similar to the genera Globicornis Latreille, 1829 , Turcicornis Háva, 2000 and Dearthrus LeConte, 1861 , but differs from them by the characters mentioned below. The new subgenus differs from the genus Orphinus Motschulsky, 1858 and Thaumaglossa Redtenbacher, 1867 by the structure of the antennae¡ the antennae consist of 10 antennomeres in new subgenus and 11 antennomeres in Thaumaglossa Redtenbacher, 1867 and Orphinus Motschulsky, 1858 .

Etymology. The compound name is derived from the name of Socotra Island and the ending -cornis marking its affinity to the genus Globicornis . Masculine gender.
