(Appendix 4: Fig. 42)
Type Material (2). Holotype female labeled “ MEXICO: Aguascalientes / 13 miles west of/ Aguascalientes / July 5, 1984 / Carroll, Schaffner,/ Friedlander” (TAMU) and with my red holotype label. One female paratype with the same data (UNSM) and my yellow paratype label.
Description. Holotype female (Fig. 42a). Length 9.2 mm; width 5.3 mm. Color: Dorsal surface tomentous and shiny, yellowish brown. Pronotum tomentous in front of scutellum, shiny elsewhere, black with reddish brown markings, vittae evident. Elytra tomentous on basal half, rest shiny, with black irregular markings. Ventral surface including legs, dark brown. Head: Frons slightly raised at middle, densely punctate; punctures deep, moderate in size, frequently confluent, sparsely setose; setae yellowish, small. Clypeus subtrapezoidal, lateral margins weakly raised, strongly laterally expanded anteriorly in dorsal view; apex not raised, moderately sinuate; surface as on frons. Antennal club shorter than stem. Pronotum: Surface moderately densely punctate; punctures lunulate, moderate in size, denser toward sides. Surface on sides only sparsely setose; setae short, yellowish. Apex with small swelling. Sides weakly angulate. Base impunctate, evenly rounded. Scutellum impunctate, apex sharp. Elytra: Surface densely punctate; punctures moderate in size, striae bearing 2–3 rows of geminate and irregular punctures; apex and sides moderately to strongly rugose. Surface glabrous. Pygidium: Surface subconcentrically striate; striae dense, discontinuous, moderately densely setose; setae short to moderate, yellowish. Legs: Protibiae robust, teeth equidistant. Mesotibial carina weakly developed, metatibial carina moderately developed. Metatibiae moderately expanded apically, metatarsi shorter than metatibiae. Venter: Mesometasternal process strongly compressed laterally, extending anteriorly to same level as mesocoxae, apex evenly rounded. Mesepimera, metasternum, metepimera, and metacoxae setose, setae as on legs. Metasternum rugose, moderately to densely setose laterally, glabrous and impunctate at middle, median sulcus strongly impressed. Abdomen strongly convex in lateral view.
Variation. The female paratype is similar in all respects to the holotype except in the following: Length 8.7 mm; width 5.0 mm.
Diagnosis. This species is separated from other species in the group by the small body size, apex of pronotum with small swelling, pronotum and elytra densely punctate, and mesometasternal process strongly compressed laterally, extending anteriorly to same level as mesocoxae, and with an evenly rounded apex.
Notes. Males are unknown. One male specimen collected in the same area and deposited in my collection might constitute the male of this species. This specimen is similar to E. quadricollis in many aspects except for the genitalia. I am hesitant to consider it conspecific with E. hidrocalida because of its larger size (length = 11.2 mm; width = 6.5 mm) compared to the size of the small females of E. hidrocalida (females in the genus tend to be of the same size or larger than the male). This male specimen will remain undetermined until more material becomes available.
Temporal Distribution. July (2) (Fig. 42c).
Geographic Distribution. Known only from Aguascalientes, Aguascalientes, Mexico (Fig. 42d).
Etymology. The Spanish “ hidrocalida ” is a feminine word given to the inhabitants of Aguascalientes, Mexico, the type locality.
