Reproductionovovivparous (Greer 1966) 
TypesHolotype: BMNH 83.4.16.38, possibly lost
Holotype: BYU 16858, adult male. Collected at 6500 feet on July 18, 1960 by Wilmer W. Tanner and W. Gerald Robison. [labialis]
Holotype: CAS 89765 [atavus] 
DiagnosisDiagnosis (genus): The genus Conopsis is comprised of viviparous snake species with burrowing habits. These snakes are relatively small, adults of all species ranging from 100 to 330 mm in snout-vent length SVL; and from 120 to 377 mm in total length TL; body subcylindrical; head short; snout pointed; pupil round; 17 rows of smooth scales at midbody; anal and caudal scales divided; 12 to 14 conic maxillary teeth, with a distinctive groove at least on the last tooth; two internasal scales; a preocular; two postoculars; a rostral ended in a tip; nasal scale pierced by the nostril; frontal scale hexagonal; temporal formula 1+2; 2.5 to 3 upper labials before eye; hemipenes subcylindrical, with reticulate ornamentation, and several large spines at the base. Prefrontals and internasals may be fused or divided; loreals may or may not be present (20% of sample examined); genial shields divided by a scale in 90% of specimens, but may be fused or divided by two scales. Upper labials 7, in 90% of the specimens (they vary from 5 to 7); lower labials 6 in 80% of the specimens (varying from 4 to 7). Ventral scales 120–127; subcaudals 29–39. Coloration and body markings vary considerably, both dorsal and ventral patterns. Dorsal pattern consists of dark spots, blotches or bands on a variable ground color, that goes from light brown, cinnamon, grayish, and olive green tones. Dorsal spots may be constituted from a series of hexagonal to elongated marks, a tessellated pattern, or lines along the body. Some snakes have no dorsal pattern of spots. There is less variation ventrally, generally the belly is yellowish, although it may be reddish or grayish. Ventral spots may be present in a series of central dots, large or small, medial, intercalated or paired, some acuta with black edged ventre. 
CommentType species: Conophis nasus GÜNTHER 1858 is the type species of the genus Conopsis.

Phylogenetics (Goyenechea & Flores in prep.) suggests that Chionactis and Gyalopion may be the sister groups to Conopsis.

The type locality of Conopsis nasus is “California”.

Diet: invertebrates 
EtymologyThe specific name is derived from the Latin word nasus, meaning "nose."

The genus name Conopsis was derived from the Greek words cono, meaning "cone" and -opsis, meaning "having the appearance of," in reference to the conical shape of the snout.
