Blaiseus guatemalensis Douglas , new species

(Figs. 6, 21)

Material examined. Two males.

Type material. Holotype: Male labeled: ‘‘GUAT.Senahu,AVP/ VI.26.1965/ J.M.Campbell’’; [red] ‘‘ HOLOTYPE / Blaiseus / guatemalensis/ Douglas 2006,’’ with genitalia in microvial attached to pin ( CNCI) . Paratype: one male labeled: ‘‘ Guatemala, Zacapa / 22 km N Estancia Virgen / 6000 9 June 3, 1991 / E. Giesbert coll.’’; [yellow] ‘‘ PARATYPE / Blaiseus / guatemalensis/ Douglas 2006,’’ with genitalia in microvial attached to pin ( FSCA) .

Type locality: Guatemala, Dept. of Alta Verapaz, Senahu (elevation 1,000– 1,300 m, 15.42 ° N, 89.82 ° W) .

Diagnosis. Pterothorax: Elytra with apex upturned (including suture). Legs: Protibiae without posterior tooth at midlength (Fig. 6) Aedeagus: Median lobe broadest near apex ( Fig. 21 ).

Description. Male: Length 8.0–9.0 mm, habitus similar to B. chiapasensis new species ( Fig. 9 ). Integument without lighter coloured patches on elytra. Head: Antennae reaching beyond metacoxae; labrum concave in lateral view; nasale with circular pits antero-mesad of antennal fossae. Prothorax: Hypomeron with hind edge sinuate immediately meso-ventrad of hind angles. Prosternum with ventral surface of prosternal process surface not carinate laterally. Pterothorax: Scutellum with posterior sides straight meeting at a rounded point. Elytra with apex upturned (including suture), posterior surface flattened; interval 5 costate ( Fig. 16 ); epipleurae with globular serrations posteriorly. Hind wings with CuA1 not forked at junction with MP3+4. Legs: Protibiae with only vague expansion at midlength and apex flared (Fig. 6), (fossorial); tarsomere 4 with small ventral lobe. Male genitalia: Aedeagus with median lobe broadest near apex; parameres with free part of dorsal (setose) apices 1/3 length of ventral apices ( Fig. 21 ); inner apices present but unsclerotized. Female: Unknown.

Comments. Evidence that this species is distinct from B. chiapasensis new species, the most similar species, is listed under that species.

Known from the type locality and locality of the paratypes. Label data of paratype apparently refers to the mountain range that includes Cerro Raxon and Cerro Pinalon based on department and elevation (elevation 1,800 m, 15.1 ° N, 89.8 ° W). This is the only Blaiseus species known from Guatemala .
