Nomindra , new genus

TYPE: Nomindra kinchega , new species.

ETYMOLOGY: The generic name is an arbitrary combination of letters considered feminine in gender.

DIAGNOSIS: Specimens resemble those of Myandra , especially in genitalic conformation, but differ in having enlarged posterior median eyes and an abdominal dorsum with a shorter scutum in males and a characteristic color pattern, with pairs of pale spots in an inverted v-shaped position and a half moonshaped pale spot in front of the spinnerets.

DESCRIPTION: Small spiders, total length of males 1.5–2.2, of females 1.9–3.4. Carapace broadly oval, narrowed in front to less than half its maximum width; surface finely reticulated, weakly coated with shiny or gray, recumbent, plumose setae, without tubercles, few long, dark, erect setae present on clypeus; thoracic groove longitudinal, weak or absent. Eight eyes in two rows, anterior medians large, elevated, circular, dark, PME largest, irregularly rectangular, flat, light; laterals subequal, oval, light; from above, anterior eye row slightly procurved, posterior row strongly procurved (fig. 8), from front, both rows strongly procurved; anterior medians separated by half their diameter or less, closer to anterior laterals; posterior medians separated by about J of their width, about as far from posterior laterals; anterior, posterior laterals separated by about half their radius; median ocular quadrangle slightly wider in back than in front and than long. Clypeus curved downwards. Chelicerae vertical, paturon with low boss, promargin with row of long, curved setae, three teeth, middle tooth largest, retromargin with two smaller, more widely separated teeth; chilum wide, unipartite, triangular. Labium wider than long, inverted u-shaped. Endites rectangular, convergent, with oblique depression; serrula present, curved; anteromedian edges bearing wide patch of stiff, white setae. Sternum shield-shaped, anteriorly straight, widely separating coxae IV posteriorly, deeply depressed opposite intercoxal spaces, with only indistinct extensions between coxae but with large, triangular extensions to coxae; surface finely reticulated, with few setae. Pedicel composed of two dorsal sclerites (anterior sclerite semicircular), one wide ventral sclerite with inverted v-shaped incision, anteriorly almost reaching posterior tip of sternum. Abdominal dorsum with pairs of pale spots in inverted v-shaped position, or pale chevrons on top, half moon-shaped pale spot in front of spinnerets, narrow anterior scutum in males; cuticle covered with recumbent, gray or cinnamon, plumose setae; epigastric scutum weakly sclerotized; colulus apparently absent but wide, recurved posterior spiracle apparently present just anterior of posterior median spinnerets. Six spinnerets, anterior laterals greatly elongated, contiguous or slightly apart, equal to roughly half of total abdominal length, greatly advanced anteriorly, originating at position about one-half of distance between epigastric furrow and anal tubercle, point of origin marked by two weakly sclerotized, half moon-shaped strips bearing macrosetae at midline (fig. 15); posterior medians small, narrow, situated anterior of posterior laterals, separating them, those of females apparently with two or three enlarged cylindrical gland spigots in single, longitudinal row; posterior laterals bisegmented, slightly longer than posterior medians. Legs elongate, leg formula 4123, coated with recumbent, plumose setae; coxa IV equal to coxa I or longest; coxae, trochanters without dorsal tubercles, trochanters equal in length, distal edges fitting inside proximoventral margins of femora; femora I, II long, proximal portions slightly incrassate; metatarsi without distal preening brushes; tarsi elongated, with two slender, toothless claws on onychium, weak claw tufts composed of few pairs of spatulate setae (fig. 244); tarsi I, II without, III, IV with cuticular cracks at about threequarters of their length, distinctly bent at that point; trichobothria present, in one row on tarsi, metatarsi, tibiae. Female palpal femur without strong spines; female palpal tarsus without distal claw, ventral scopula, or dorsal pad of setae. Male palpal cymbium long, at least 2.2 times longer than wide, tip conical; palpal tibia about 1.5 times as long as wide, with distal, retrolateral apophysis; embolus situated prolaterally, tip nestled in longitudinally grooved conductor; median apophysis hook-shaped, reduced, or absent, terminal apophysis triangular, needle-shaped, or absent. Epigynum with broadly oval, anterior atrium; spermathecae globular, oval or sausage-shaped, situated posteriorly.
