Chrysopodes (Neosuarius) pecki Tauber and Tauber, 2010: 67 View in CoL [USNM, Holotype (by original designation): “ Ecuador, Galápagos Archipelago, Isla Isabela, Volcan Wolf, 4 km NE Puerto Bravo”].

Diagnosis. Chrysopodes (Neosuarius) pecki , the third endemic species of Chrysopodes (Neosuarius) from the Galápagos, is known only from two extinct volcanoes on Isabela

Island (Volcán Wolf and Volcán Alcedo), where it is sympatric with C. (N.) nigripilosus . The adults share many features with C. (N.) nigripilosus and C. (N.) nigricubitus , but they differ in having a pair of brown spots on the dorsum of the head, posterolateral to the vertex, elongate pronota ( Fig. 40e View Figure 40 ). This species is the only one of the three Galápagos species that has forewings exceeding 13 mm in length. Like C. (N.) nigripilosus , the wings do not show dark suffusion around the crossveins. But like C. (N.) nigricubitus , the second cubital crossvein is very dark and it bears a dark brown swelling mesally; however, the swelling is smaller than that on most C. (N.) nigricubitus wings ( Fig. 63 View Figure 63 ; Tauber and Tauber 2010, Table 2).

Although the males of C. (N.) pecki closely resemble those of C. (N.) nigripilosus and C. (N.) nigricubitus , there are some distinguishing features ( Fig. 65 View Figure 65 ). For example, the gonarcus (length of arms, bridge width) is larger than that of either C. (N.) nigripilosus or nigricubitus ( Tauber and Tauber 2010, Table 5). Second, as in C. (N.) nigricubitus , the horizonal apodeme along the ventral margin of T9+ectoproct is relatively straight, and it has a well sclerotized, unforked, pointed tip with a small ventral knob ( Fig. 64d View Figure 64 ). Other differences were noted in the original description ( Tauber and Tauber 2010).

Female C. (N.) pecki are distinguished by their very dark brown coloration on the fifth abdominal sternite, light brown pigmentation basally on S6, and cream coloration on the distal portion of S6 and all of S7 ( Fig. 57d View Figure 57 ).

Description. Available in Tauber and Tauber (2010).

Larvae, Eggs, Biology. Unknown. Adult specimens were collected in April and May.

Type material. Chrysopodes (Neosuarius) pecki Tauber & Tauber. The holotype (a male, pinned) is in the National Museum of Natural History, Smithsonian Institution , Washington, D.C. ( USNM). Its labels read: (1) “ECU: Galáp: Isabela / V. Wolf, 4 kmNE. P. Bravo / humid for, 17.V.96 / uv light / S. Peck, 96–192”; (2) “ HOLOTYPE / Chrysopodes (Neosuarius) pecki Tauber & Tauber , des. 2010” [red]. There are two paratypes (females, in alcohol) in the Institut Royal des Sciences Naturelles de Belgique, Bruxelles, Belgium ( IRSN). Their labels read: (1) “ Ecuador, Galápagos Arch., Isla Isabela , Volcán Alcedo, SE crater rim at “Geyser”, 1000 m, 3/IV/1996, L. Baert, K. Desender & J.-P. Maelfait, B96/0074”; (2) “ PARATYPE / Chrysopodes (Neosuarius) pecki Tauber & Tauber , des. 2010” [yellow].

Specimens examined. Type material only.

Known distribution. Two extinct volcanoes (Volcán Wolf and Volcán Alcedo) on Isabela Island (Galapagos).

Variation. Sample size very small.
