Diagnosis. Specimens of Glyptasida aegra are diagnosed on the basis of the following unique combination of characteristics: body shining, pronotum with small and widely distributed punctures ( Fig. 11 ); discal costae of elytra flattened with medial costae nearly absent ( Fig. 5 ), elytral setae without node at base ( Fig. 13 ).

Description. With general features of Glyptasida , and the following specific characteristics: GHW 2.8–4.1 mm; GPW 4.7–9.6 mm; GEW 7.7–11.8 mm; HL 1.9–4.1 mm; PL 3.9–5.2 mm; EL 11.3–16.5 mm; TL 17.9–25.3 mm; Ratio of GPW/GEW 0.63–0.89. Body stout, shining, black, not covered with debris; pronotum broad, lateral edge arcuate; pronotal punctures small ( Fig. 11 ), punctures widely distributed ( Fig. 11 ); elytra flattened dorsally ( Fig. 5 ), costae less elevated, medial costae indistinct; elytral setae without nodes at base ( Fig. 13 ). Male genitalia with median lobe basally rounded, similar to G. sordida ( Fig. 20 ).

Notes about type material. Pelecyphorus aeger . We examined one male specimen. The male holotype has the following label information: [round label dark green above and white below]/ “ Type 4528”/ [handwritten det. label] “P. ae ger Lec.”/ “ Jan.–Jul. 2005 MCZ Image Database.” The holotype has the following identifying features: left antenna with only four antennomeres; large pin hole through both elytra extending though venter; right hind tarsus with two basal tarsomeres only. The dark green locality label represents a locality in New Mexico (Phil Perkins pers. comm.).

Glyptasida sycophanta . We examined one male and one female specimen. The male lectotype (here designated) has the following label information: “Alpine, Tex Wickham Aug 16 17 ”/ “ CASEY bequest 1925”/ “ TYPE USNM 46440”/ [handwritten det. label] sycophanta Csy. ” The lectotype has the following identifying features: left mesotarsus with one basal tarsomere only, right mesotarsus with two basal tarsomeres only, and abdominal ventral apical segment slightly extended exposing the aedeagus.

Taxonomic Notes. According to Casey (1912:96), the distinguishing characteristics of G. sycophanta are “pronotum with much smaller, widely separated though irregularly distributed punctures” ( Fig. 11 ). In examining the type specimen of G. sycophanta we determined that these features are exactly the same as in the type specimen of Glyptasida aegra . In both type specimens the discal costae are flattened with the medial costa nearly absent. After examining non-type specimens received from collections, species descriptions, and type specimens, we determined that G. aegra and G. sycophanta are synonyms.

Distribution. The geographic range of this species is southern New Mexico and southwestern Texas ( Fig. 28 ).
