Lionothus parvoculus Peck and Cook , new species

( Fig. 11 , 22 )

Description. Length (pronotum + elytra) = 2.40–2.60 mm; greatest width = 1.48–1.72 mm. Reddish brown, shiny. Head punctures of moderate size, irregularly spaced, more dense laterally. Antennal grooves not well defined. Mandibles elongate, not forming semicircle when closed; both mandibles edentate, Antennal club slender; antennomere 8 disc-like, narrower than apex of 7; apical antennomere longer and narrower than 10. Eyes reduced in size, length about one-third length of head. Pronotum broad, sides weakly rounded, posterior angles obtuse, basal margin rounded. Pronotal punctures moderately small and dense. Elytral strial punctures round and deep, smaller toward base, separated by ±1 diameter. Interstrial punctures fine and sparse; few large punctures between striae VI and VII. Metasternum finely punctate medially; coarsely, densely punctate laterally. Male mesofemur unmodified. Male mesotibia weakly concave on inner margin. Abdominal sternites III–VII each with basal transverse row of large punctures. Median lobe of aedeagus ( Fig. 11 ) cylindrical, strongly curved dorsoventrally, flattening to paired apices in apical one-fourth. Parameres slender, sinuate apically, not reaching apex of median lobe. Internal sac as in Fig. 11 .

Type material. Holotype, male, in SBPC, with label data: “N. MEX: Lincoln Co. / Sierra Blanca, 8000’/ 15 mi NW Ruidoso / 20.VIII.75, S. Peck // Oak Flat Camp/ Oak litter Ber 317”.

Paratypes, 20, as follows: same data as holotype (5, SBPC) ; “NMEX: Santa Fe Co. / 14 mi NE Santa Fe / 18.VI–3.VII.79,/ S&J Peck, 9600’/ aspen w/stream” (5, SBPC) ; “ARIZ: 10miNW Flagstaff / San Francisco Mts. 9500’/ 18–24.VII.79, S&J Peck/ spruce-fir-aspen/ meadow, malaise” (5, SBPC) ; “ARIZ: Flagstaff / Oak Ck. Can. 5900’/ 17–25.VII.79, at/ Sterling Can./ riparian woods/ malaise, S&J Peck” (3, SBPC) ; “ARIZ: Cochise Co. / Rustler Park , 9000’/ VIII-31-1976 / Fred G. Andrews // Berlese soil/ around Amanita/ muscaria” (1, CSCA) ; “ Chir. Mts. Ariz./ VIII-16-68 7500-/ 9500’ Sweeping/ V. Roth ” (1, CSCA) .

Distribution. The species is known only from Arizona and New Mexico in the United States ( Fig. 22 ).

Seasonality. Adults have been collected in the months of June to August.

Bionomics. Adults have been collected in riparian forest, mixed forest, oak woodland, and upper elevation spruce-fir-aspen forest. They were taken mostly by flight intercept and malaise traps, and also in litter and by sweeping.

Etymology. Latin “ parvoculus ”, small eyes, refers to the reduced eye size of this species.
