Subfamily Ceratolasmatinae Shear, 1986 View in CoL

Ceratolasmatidae Shear, 1986: 13 (compr. Acuclavella View in CoL , Ceratolasma View in CoL , Crosbycus View in CoL , Hesperonemastoma View in CoL ); type genus Ceratolasma Goodnight & Goodnight, 1942 View in CoL , by original designation;— Giribet et al. 2010: 422 (compr. Acuclavella View in CoL , Ceratolasma View in CoL , Crosbycus View in CoL ).

Ceratolasmatinae View in CoL ; new rank, new composition (compr. Acuclavella View in CoL , Ceratolasma View in CoL ).

Diagnosis. Dyspnoi of the family Ischyropsalididae with a narrow western Nearctic distribution ( USA: N- California, Washington, Idaho). Defined by peculiarities of male genital morphology and morphological similarities concerning palps, armature of dorsum and tuber oculorum, supported by molecular phylogenetic evidence. Palps short and stout, tibia and tarsus similar to each other and almost equal in length. Chelicerae of moderate size; males with large glandular fields dorso-medially on basal cheliceral segments, glands associated with rather unspecialised but in most species large, plateau-like apophyses exposing the glandular fields to dorsal and dorso-caudal side. Truncus penis as described for Ischyropsalididae but generally slender; glans penis simple and conical, rarely inflated, with a long, narrow, sclerotised ventral plate, gradually tapering into a long stylus being simple, straight, but slightly contorted in few species and set with indistinct, hook-like structures. Ventral plate irregularly set with small uniform spines, pronounced and structured setation otherwise lacking. Tuber oculorum set with a long blunt spine. Dorsal armature with blunt tubercles and partially varying numbers of large paired cones or spines on opisthosoma. Two bump-like enlarged metapeltidial structures.

Genus Acuclavella Shear, 1986 (4 species)

Acuclavella Shear, 1986: 13 View in CoL ; type species Acuclavella cosmetoides Shear, 1986 View in CoL by original designation.

Etymology. Gender feminine; Latin neologism for “acute little spines” referring to the dorsal armament of the body.

cosmetoides Shear, 1986: 15 View in CoL ; loc. typ.: USA, Idaho, Clearwater Co., Pierce.

merickeli Shear, 1986: 20; loc. typ.: USA, Idaho, Idaho Co., 20 mi ESE Lowell, Meadow Creek.

quattuor Shear, 1986: 22 View in CoL ; loc. typ.: USA, Idaho, Idaho Co., 10 mi E Slate Creek.

shoshone Shear, 1986: 18; loc. typ.: USA, Idaho, Shoshone Co., Hobo Cedar Grove.

Genus Ceratolasma Goodnight & Goodnight, 1942 View in CoL (1 species)

Ceratolasma Goodnight & Goodnight, 1942: 3 View in CoL ; type species Ceratolasma tricantha Goodnight & Goodnight, 1942 View in CoL by monotypy and original designation.

Etymology. Gender neuter; Greek, combination of “keratos” (genitive of “keras” = horn) for the horn-like processes, and „elasma“ (plate), referring to similar prosomal structures in other genera of Dyspnoi , as e.g. Dicranolasma , Ortholasma or Dendrolasma .

tricantha Goodnight & Goodnight, 1942: 3 View in CoL ; loc. typ.: USA, Oregon, near Forest Grove, Clear Creek;— Gruber
