Etymology.
Latin
directus
, referring to the male chelicerae projecting almost straight forward.
Diagnosis.
Differs from other species by the presence of two cusps near the base of the male cheliceral fang (
Figs 10–11
), the long embolus and the abruptly narrowed distal end of the retrolateral tibial apophysis of the male palp (
Figs 7–9
), the large window of the epigynum (
Fig. 13
), and the large and spherical spermathecae of the vulva (
Fig. 14
). Female genitalia resembles that of
Euophrys evae
Żabka, 1981
, but can be distinguished by the narrower copulatory duct and the larger spermatheca of the vulva (
Fig. 14
).
Description.
Male
(
holotype
, UBC-SEM AR00077). Carapace length 3.6 (variation 3.5–3.8, n=6); abdomen length 5.0. Chelicera (
Figs 10–11
): dark red brown; elongate and extending forward; promargin with four teeth and retromargin with one big tooth; fang with two cusps near the base. Palp (
Figs 7–9
): sandy yellow. Retrolateral loop of sperm duct wide, occuping about three quaters of the bulb width. Embolus coiled for about half a circle. Retrolateral tibial apophysis thick proximally and narrowed abruptly near distal end. Measurements of legs: I 13.7, II 9.0, III 10.7, IV 9.3. Color in alcohol (
Fig. 5
): carapace yellow orange with indistinct gray markings; abdomen gray brown, with yellow orange speckles and yellowish stripes; legs light yellow to brown.
Female
(
paratype
, UBC-SEM AR00078). Carapace length 2.8 (variation 2.8–3.1, n=5); abdomen length 4.9. Chelicera (
Fig. 12
): with two promarginal teeth and one retromarginal tooth. Measurements of legs: I 6.3, II 5.7, III 7.5, IV 6.7. Epigynum (
Figs 13–14
): window large with a narrow median septum; opening to copulatory duct at anterior lateral edge of the window. Copulatory duct short and slightly curved; spermatheca large and spherical. Color in alcohol (
Fig. 6
): similar but lighter than that of male.
Natural history.
Specimens were collected by beating forest understory vegetation.
