Omalaspis gibsoni Ros-Farré & Pujade-Villar n. sp.

( Figs 5b View FIGURE 5 & 6b View FIGURE 6 )

Type material. ( 1 ♂). HOLOTYPE male ( CNCI), 23-VII-1961, Doolittle Ranch, 9800’ Mt. Evans , COLO ( USA), S. M. Clark.

Diagnosis. Omalaspis gibsoni n. sp. is morphologically similar to O. asiatica , both having interfoveal line short and narrow, and not well defined. But in O. gibsoni , the scutellar disc is coarsely rugose, without microsculpture, and the scutellar foveae are rounded, while in O. asiatica , the scutellar disc is weakly rugose with noticeable coriaceous microsculpture, and scutellar foveae are laterally oval.

Description. Length. Male 2.5 mm; female unknown.

Coloration. Head and mesosoma black. Metasoma dark brown. Antenna and leg brown. Wing membrane hyaline, veins of wing brown.

Head. Frons coriaceous, slightly rugose. Frontal carinae present, with a furrow between them. Lateral frontal carinae conspicuous, space between them and compound eyes coriaceous and with transverse carinae. Supratorular impression conspicuous. Ocelli slightly prominent. Vertex in dorsal view coriaceous, rugose, with central shiny area. Vertex posterior coriaceous. Occiput coriaceous. Genae sharply margined and expanded, with sinuate transverse carinae, space between carinae shiny and slightly coriaceous.

Antenna. Filiform. First flagellomere clearly excavated but not strongly. Antennal formula: 5(2): 1.5(1.5): 5(1.5): 4.5(1.5): 4.5(1.5): 4.5(1.5): 4(1.5): 4(1.5): 3.5(1.5): 3.5(1.5): 3.5(1.5): 3.5(1.5): 3.5(1.5): 5.5(1.5).

Mesosoma. Lateral surface of pronotum coriaceous, with very short and scarce transverse carinae dorsally, basally with conspicuous transverse carinae, central area coriaceous. Mesoscutum coarsely coriaceous. Parascutal sulcus shiny. Median ridge complete, conspicuous, antero-admedian lines conspicuous slightly confluent, reaching 1/3 mesoscutal length. Median mesoscutal furrow very deep, coriaceous, with some transverse carinae. Notauli very deep, wide medially, narrow anteriorly and posteriorly, with spaced transverse carinae and coriaceous. Mesosoma, in lateral view, slightly humped. Mesopleuron slightly sculptured anteriorly, smooth posteriorly. Scutellum 0.8 times scutum length. Interfoveal line reaching 1/3 scutellar disc length, strongly sinuate. Scutellar foveae almost smooth. Scutellar disc strongly rugose. Lateral scutellar margin confluent posteriorly, posterior margin of scutellum curved, wide.

Wing. Radial cell 2.0 times longer than wide. R2 straight, curved near margin of wing.

Distribution. Nearctic, USA (Colorado).

Etymology. This new species is dedicated to our Canadian friend and colleague Gary Gibson (CNCI).

Biology. Unknown.
