Description

Habitus as in Fig. 1a. Body length 10.3-10.8 mm. Coloration of head and pronotum dark metallic purple-blue (Fig. 2a); antennae and mouthparts orange; elytra and abdomen shiny brown, except intersegmental membranes yellow, sternite VIII and posterior 1/4 of sternite VIII orange; legs and pronotal hypomeron orange-brown.

Head transverse, width: length ratio = 1.47; surface of epicranium flat; with medium-sized umbilicate punctures throughout surface except medially, distance between punctures varies but typically equals diameter of puncture. Eyes large, length of eyes / length of head = 0.58, distance between eyes as wide as 1.44 times length of eye.

Pronotum subquadrate, width: length ratio = 1.13; with scattered large umbilicate punctures, distance between punctures varies but typically equals 0.5-1 times diameter of puncture. Mesoscutellum with medium-sized punctures, punctures not confluent. Elytra with large, almost confluent punctures; each row with approximately 11 punctures (measured at middle of elytron). Abdominal tergites III-V with strongly delineated curved (arch-like) carina.

Secondary sexual structures. Males with posterior border of sternite VII with deep U-shaped emargination; sternite VIII with deep, broad U-shaped emargination medially; sternite IX with deep V-shaped emargination medially. Females with no obvious secondary sexual structures. Aedeagus as in Fig. 6; paramere divided to near base into two lobes; lobes narrower and subequal in length to median lobe; in dorsal view each lobe converging to rounded apex; in lateral view paramere slightly convex; with peg setae (sensory spinules) as shown in Fig. 6c, scattered throughout length of two lobes. Median lobe in dorsal view converging to narrow pointed apex; with single narrow dorsal tooth; in lateral view becoming much narrower near apex.

Diagnosis

Scaponopselaphus diaspartos can be distinguished from S. mutator based on the following characters: epicranium flatter and distance between eyes longer in S. diaspartos than in S. mutator ; pronotum punctation more dense in S. diaspartos than in S. mutator (Fig. 2); and elytra punctation more sparse in S. diaspartos than in S. mutator (Fig. 1). Additionally, the following characters can be used to distinguish between males of the two species: in S. diaspartos posterior border of sternite VII with deeper median emargination than in S. mutator ; in S. diaspartos peg setae are more scattered in the paramere (Fig. 6c) than the peg setae of S. mutator (Fig. 7c); and the median lobe of in S. diaspartos is as long as the paramere (Fig. 6a) while the median lobe in S. mutator is longer than the paramere (Fig. 7a).

Etymology

The specific epithet is derived from the modern Greek word διάσπαρτος (scattered) and refers to the distribution of the peg setae on the parameres. The epithet is a noun in apposition.

Distribution

Known from Vaupés, Colombia.
