Spiroctenus tricalcaratus

Only males of Spiroctenus tricalcaratus are known to science.^[3] The spider is pale ochraceous in color. The carapace shows faint greenish or fuscous patches radiating inwards from the margins. The cephalic region is yellowish with a dark stripe along the middle and one at each lateral margin.^[3]

The opisthosoma has a median black or blackish brown stripe that is abbreviated posteriorly and widened anteriorly into a large patch. This is flanked on each side by a row of short, obliquely transverse, similarly colored stripes that do not unite with the median stripe. The underside shows a dark spot slightly in front of the larger spinnerets. The sides have a larger spot just above these spinnerets but are otherwise without spots or stripes. The distal part of the first leg is reddish. The total length is 11-14 millimeters.^[3]

The species is listed as Data Deficient for taxonomic reasons, as females remain unknown and the current species range requires further study.^[2]
