Descriptions of New Taxa

A Supplement to Salticidae Diagnostic Drawings Library

by Jerzy Proszynski 2000

Descriptions of new species, in print now, or in preparation for print, made provisionally available for the Users of the Diagnostic Drawings Library because of long delay in publication.
Attention: the International Code for Zoological Nomenclature does not recognize taxonomic names unless description is printed on paper. However 1999 edition of the Code recognizes such description on certain conditions which include depositing disk in 5 recognized libraries. This condition is fulfilled for the June 2000 version.

Havaika jamiesoni sp. n. Proszynski, 2001 (in press)

See Drawings See List of Species

Material: Holotype. - male (with palpal organ separatein smaller vial), allotype - female, two male paratypes, 9 imm. - " Havaika A" - Hawaii, Kauai Co., Koke's State Park, Nu'Alolo Trail. Elev. 3600 ft. 23 January 1998. Coll. J.W. & E.R. Berry.

Etymology. - Named for Mr. Dean Jamieson, a retired entomologist on the island of Kauai in Hawaii who was of great help to the collector, Dr. J. W. Berry, when he was collecting there. Mr Jamieson was instrumental in collecting of many species of Salticidae by D Berry, by showing all of his favorite collecting places, and participating in collection on many occasions.
Diagnosis. Medium size species (about 4-5 mm long), male palps with tibia about as long as cymbium, embolus short, arising in about 1/2 of length of bulbus. Abdominal pattern with median streak of pairs of whitish spots and transverse white line in 2/3rd of abdomen. Epigynum - proportions and structure are shown on Figs. 8-9. Male seems to be rather similar to the type specimen of Havaika verecunda, from which differs, however, by embolus originating at about 1/2 of the length of the bulbus.
Description. - Male (n=1) total length 4.44 mm. Body proportions in mm (and in % of length of cephalothorax): length of cephalothorax 2.04 (100 %), length of eye field at eyes I .96 (47%), height of cephalothorax .98 (48%), width of eye field at eyes I 1.32 (65%), width of eye field at eyes III 1.38 (68%), width of cephalothorax at eyes III 1.44 (71%), maximum width of cephalothorax 1.50 (74%), length abdomen 2.40 (118%), maximum width of abdomen 1.32 (65%).
Cephalothorax dark brown, with a pair of indistinct streaks of whitish setae on thorax, and indistinct white setae on eye field. Face dark, with eyes I surrounded by distinct white setae, triangle of white scales dorsally between eyes AME, but no white setae on clypeus. Chelicerae dark, their apical ends lighter, with two or three vertical rows of white setae. Abdomen dark, indistinctly lighter mottled, with median darker anterior streak delimited by two pairs of whitish elongate spots, followed in posterior half by median chain of whitish rectangular spots. There is a transverse white spot, or line, reaching margins of abdomen, in 2/3rd of length of abdomen, the anterior edge of abdomen is marked by thin white line, there is also a pair of marginal, indistinct, whitish spots in the mid-length of abdomen . Pedipalps with cymbium appearing slightly longer than tibia (in difference to majority of species, where tibia is distinctly longer). Basis of embolus located laterally on bulbus, near the middle of its length (that is difference with H. verecunda). Embolus of about the same thickness along majority of its length, gently bent, following curvature of anterior edge of bulbus. Legs dark, with basal halves of femora II=IV light, anterior tibia, metatarsus and tarsus I brown. Length of segments of legs: tarsus I .66, II .48, III .48, IV .48; metatarsus I .84, II .54; III .72, IV .78; tibia I 1.14, II .60, III .66, IV.66; patella I .84, II .60, III .60, IV .60; femur I 1.32, II .96, III 1.20, IV 1.04. Legs formula (and length of 5 segments in % of leg I) I (100 %), III (76%) = IV (76%), II (66%).

Female (n=1) total length 4.32 mm. Body proportions in mm and in % of length of cephalothorax: length of cephalothorax 2.04 (100 %), length of eye field at eyes I 96 (45%), height of cephalothorax .90 (44%), width of eye field at eyes I 1.20 (59%), width of eye field at eyes III 1.32 (65%), width of cephalothorax at eyes III 1.38 (68%), maximum width of cephalothorax 1.38 (68%), length abdomen 2.28 (112%), maximum width of abdomen 1.38 (68%). General appearance resemble male, with somewhat more pronounced light suffusing of the dark abdomen, with transverse white line across abdomen somewhat thinner and chevron resembling. Legs and pedipalps generally lighter, but leg I dark. Length of segments of legs: tarsus I .48, II .42, III .48, IV .48; metatarsus I .48, II .48; III .60, IV .66; tibia I .72, II .48, III .60, IV.60; patella I .72, II .54, III .60, IV .60; femur I 1.08, II .84, III 1.04, IV 1.08. Legs formula (and length of 5 segments in % of leg I): I (100 %), III (98%) = IV (98% ), II (79%). Epigynum with dark median vaginal roof relatively narrow and long, reaching anterior rim of the "window". Posterior part of spermathecae narrow and long, running along spherical central part of spermathecae and ending in front of them.
