Ulosonia depressa Champion 1886: 164 .

Type Material: LECTOTYPE (male) labeled: (a) Cuernavaca (b) “ Mexico / Salle Coll.”; (c) “Godman-Salvin / Coll. Biol. / Centr.-Amer.”; (d) on grey paper “1899”; (e) “Ulosonia ♂ / depressa Ch. ”; (f) on blue paper “Tenebrionid Base / Aaron D. Smith / Catalog # 19609” (g) “ LECTOTYPE / Hypogena / depressa / Grey & Smith, 2020” Designated here. ( BMNH, Fig. 25 View FIGURE 25 ). Champion did not designate a holotype for this species, so in order to maintain the taxonomic concept for this species a lectotype is designated from Champion’s syntype series.

Diagnosis: This species is very similar to H. tricornis in size and form. The horns, while similar to those of H. tricornis but not as long. The puncturing on the pronotum in both the male and female are of two sizes. The coarse punctures are not concentrated only on the disc and can be found throughout the pronotum. The lateral portions of the pronotum are gradually raised to form the disc. The hypomeron is laterally rugulose, but not punctate. Most of the character states are the same in the female, except the presence of the horns ( Fig. 25 View FIGURE 25 ).

Redescription: Male. Size: 8—9 mm; 2—3 mm.

Head. Clypeal horn long; thin (4:1; 5:1); twice as thick as supraorbital horn (7:2); produced perpendicularly to head (8:1); finely punctate (9:1). Supraorbital horns long (10:1; 11:1); produced forward (13:0); bent slightly inwards (12:1). finely punctate 15:1). Anterior corners of clypeus rounded (29:1). Puncturing on vertex and frons smaller than eye facet (26:1; 28:1). Third antennomere same size as fourth and more than 1.5 times size of second (18:0; 19:2). Antennae with stellate sensoria (22:0). Gena not extending laterally past eye (36:0). Mentum trapezoidal and lightly setose (40:0;41:1). Labrum fully setose (39:1). Groove on mandible continuing to connection point on cranium (44:1).

Thorax. Pronotal puncturing biordinal in size (54:1); numerous coarse punctures scattered across pronotum (57:2). Lateral portions of pronotum gradually raised to form disc. From lateral view, pronotum not arched (58:0). Lateral margins of pronotum subparallel (61:1). Lateral edge of pronotum expanded wider than diameter of one coarse puncture (62:2). Pronotum narrowest anteriorly (59:1). Anterior portion of pronotum reaching middle of eye, but not past middle of eye (63:1). Hypomeron laterally rugulose and not punctate (75:2). Row of cuticular teeth present on posterior edge of metasternum (77:1). Mesepisternum punctate; punctures smaller than eye facets and less than one diameter from each other (71:1). Prosternum punctate; punctures smaller than eye facets (67:1); separated by more than one diameter (68:0); not bearing setae (66:0). Elytra striate (46:1); punctate (47:1); punctures farther than one diameter from each other (48:1). Elytral interstices convex and punctate (49:1); punctures larger than one fourth of strial puncture size (50:0); mostly more than one diameter from each other (51:1).

Legs. Tarsi pubescent. Protarsal outgrowths present on proximal two tarsomeres (86:1). Tibia bearing two apical spurs (85:1). More than seven socketed spines on distal half of lateral edge of protibial (81:1; 82:1). Medial marginal spines on tibia absent (83:0). Apex of tibiae bearing brush of setae (84:1).

Abdomen. First three abdominal sternites laterally rugulose (89:1; 90:1; 91:1), coarsely punctate with setae arising from punctures (94:2); remaining two abdominal sternites finely punctate.

Female. Similar to male, except as follows: Intraocular space raised and extending transversely inwards (23:2); intraocular space impinging on eye (24:1). Puncturing on vertex and frons as large or larger than eye facet (25:2; 27:2). Punctures on clypeus smaller than eye facet and spread evenly across clypeus (31:1; 32:2). Clypeus tumid (33:1).

Distribution ( Fig. 26 View FIGURE 26 ): Brazil (Pará), Guatemala (Zacapa), Honduras (Comayagua), USA (Texas, New Mexico, Arizona), Costa Rica (San José, Guanacaste), Jamaica, Bahamas, Cuba, Mexico (Baja California, Nayarit, Veracruz, Sinaloa, Oaxaca, Puebla).
