( Fig. 33 )

Diagnosis. Pselaphomorphus veracruzanus is characterized by the combination of a reddish body with yellow pilosity, and triangular pronotal lateral lobes. This species can be distinguished from P. wagneri and P. mayaorum by the shape of aedeagus, which is broader and flattened, not curving dorsally, and apically with three small spines.

Description. Male. Body length 2.4 mm. Body flattened dorsally, reddish, with yellowish pilosity. Head pearshaped (length 0.6 mm, width 0.4 mm). Head longitudinal sulcus wider behind eyes, spindle-shaped. Eyes kidneyshaped (diameter 0.15 mm). Antennal length 1.7 mm. Antennomere length as follows: 1 (0.12 mm), 2 and 3 (0.06 mm), 4 and 5 (0.12 mm), 6 (0.1 mm), 7 to 10 (0.14 mm), and 11 (0.3 mm), clava inconspicuous. Maxillary palpi light brown, with short and even pilosity. Pronotum quadrate (length 0.5 mm, width 0.5 mm). Lateral lobes triangular, squared basally, basal angle acute. Antebasal lobe rectangular, at least five times wider than long. Longitudinal and transverse sulci with similar width thoroughly. Elytra length 0.7 mm, width 0.9 mm. Humeral teeth present. Sutural and basal discal foveae present and evident, framed by basal carina. Sutural stria present. Abdominal segments I–V dorsally with length as follows: 0.4, 0.15, 0.1, 0.1, 0.1 (mm). Ventrally, segment V distally round, segment VI with elongate depression, pygidial suture present. Genitalia. Phallobase regular, with short arms. Median lobe long and flat, not curved dorsally, apically divided into three small spines: two at apex and one medially to right. Accessory lobes absent ( Figs. 33 B. 33C).

Type material. Holotype (male): “ Mexico, Veracruz 33 km. NE Catemaco, Los Tuxtlas Biological Station. 160 m. VII-1 to VIII-1-1983. S. & J. Peck. Ridge rain forest. Flight intercept trap” ( FMNH). Paratypes (2): Mexico: 2 males, same information as holotype ( MHNG).

Etymology. Named after the state of Veracruz in Mexico where the holotype was collected.
