Type Material: HOLOTYPE: (female) labeled: (a) Columbia; (b) 46-20; (c) Hypogena topino; (d) Tenebrionid Base / Aaron D. Smith / Catalog # 20166; (e) “ HOLOTYPE / Hypogena / reburra / Grey & Smith, 2020” ( BMNH). Designated here. This specimen is in poor condition, so no internal structures were examined. (See Fig. 34 ).

Diagnosis: This species can be readily identified by the long erect hairs that arise from punctures on the pronotum and the elytral striae. This species is also more elongate than other Hypogena . The type for this species is a female and does not have horns. It is assumed that as all other species in this genus have horns, this species also has a horned male. However, since most other characters are conserved between males and females of this genus, this species is distinct enough that the male could be correctly identified ( Fig. 34 ).

Description: Female. Size: 9—10 mm, 2—3 mm.

Head. Intraocular space raised and continues transversely inwards (23:2); intraocular space not impinging on eye (24:0). Antennae at least as long as pronotum (20:1). Puncturing on vertex and frons at least as large as eye fac- ets (25:2; 27:2). Punctures on clypeus smaller than eye facets (31:1); evenly distributed across clypeus (32:2). Gena does not extend laterally past eye (36:0). Antennae does not form club (17:0). Third antennomere more than 1.5 times second but same size as fourth (18:0; 19:2). Anterior edge of clypeus flat with anterior corners rounded (30:1). Mentum trapezoidal (40:0); punctate and setose (41:1; 42:1); setae long. Labrum fully setose (39:1). Mandible with distinct groove continuing to attachment point of cranium (44:1).

Thorax. Pronotal punctures biordinal in size (54:1); coarse punctures concentrated on lateral portions of pronotum (57:0). In lateral view, pronotum is not arched (58:0). Lateral edges of pronotum not parallel (61:0). Margin of pronotum narrowly expanded less than size of coarse puncture (62:1). In anterior view, pronotum forms shallow, complete arch (60:2). Anterior edge of pronotum not reaching eye (63:0). Hypomeron not smooth (75:0); prosternum coarsely punctured (67:2); punctures separated by about one diameter (68:1); setae not present on prosternum (66:0). Mesepisternum coarsely punctate (71:2); punctures separated by one diameter(72:0). Elytra striate and shallowly punctate (46:1; 47:1). Strial punctures separated by more than one diameter (48:1). Long hairs arising from strial punctures (3:1). Elytral interstices convex and punctate (49:1); punctures more than one fourth size of strial punctures (50:0).

Legs. Tarsi setose. Cuticular outgrowth present on proximal two protarsomeres (86:1). Tibiae with two apical spurs (85:1). Lateral edge of protibia with more than seven socketed spines on distal two thirds of protibia (81:1; 82:2). Spines present on medial edge of protibial, along entire length of tibia (83:1).

Abdomen. First three abdominal segments not rugulose (89:0; 90:0;91:0); first three abdominal segments coarsely punctate; punctures with hairs arising from them (3:1). Length of hairs that arise from abdominal punctures more than five times width of puncture. Last two abdominal segments finely punctate. No abdominal segments bear setae shorter than five times width of abdominal punctures (94:0).

Distribution: Colombia

Etymology: The specific epithet reburra is a Latin root meaning “one with bristling hair.” This is a reference to the long erect hairs that cover the body of this species. It is feminine.
