'''''Conasprella longurionis''''' is a species of predatory venomus sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.<ref name="WoRMS" />
Like all species within the genus ''Conasprella'', these cone snails are predatory and venomous. They are capable of stinging humans, therefore live ones should be handled carefully or not at all.
==Description== The shell of Conasprella longurionis is very elongate, narrow and subulate. The spire is high and sharply pointed, forming approximately one third of the total shell length. It consists of about fourteen to fifteen narrow, rounded whorls separated by a deep suture.<ref name="kiener">{{cite book | last = Kiener | first = Louis Charles | date = 1844–1850 | title = Spécies général et iconographie des coquilles vivantes | volume = 2 | publisher = Rousseau; J.-B. Baillière | location = Paris | pages = 308–309 |url = https://www.biodiversitylibrary.org/item/88016#page/318/mode/1up}}</ref>
The last whorl has an obtuse spiral angle and is covered with relatively coarse transverse grooves. Its base is very acute and distinctly recurved toward the dorsum.<ref name="kiener"/>
The shell colour is whitish to pale yellow, ornamented with transverse bands that may be distant or interrupted, and marked with irregular quadrangular spots of reddish or orange colour.<ref name="kiener"/>
The shell length reported by Kiener is approximately {{convert|36|mm}}.<ref name="kiener"/>
==Distribution== This species occurs in the Indo-West Pacific region, including waters off East Africa and from Taiwan to Sri Lanka.
