Paratypes. Costa Rica • 28 Females, 1 Male, CNC; DHJPAR 0047270, CNC 5342657 (there are more specimens in gel capsule attached to pin), CNC 5342658, DHJPAR 0053763, DHJPAR 0054604, CNC 5342659, CNC 5342660, CNC 5342661, DHJPAR 0054586, DHJPAR 0047262, CNC 5342662 (there are more specimens in gel capsule attached to pin), CNC 5342663, DHJPAR 0049111, DHJPAR 0051782, DHJPAR 0049101, CNC 5342664, CNC 5342665, CNC 5342666 (there are more specimens in gel capsule attached to pin), CNC 5342667, CNC 5342668, CNC 5342669 (there are more specimens in gel capsule attached to pin), CNC 5342670, CNC 5342671, CNC 5342672 (there are more specimens in gel capsule attached to pin), CNC 5342673 (there are more specimens in gel capsule attached to pin), CNC 5342674, CNC 5342675 (there are more specimens in gel capsule attached to pin), CNC 5342676, CNC 5342677.
Diagnostic description.
F 15 length> 1.5 × its width; sculpture on anteromesoscutum and propodeum coarse and deeply indicated (rarely shallow); T 1 mostly parallel-sided but slightly broadening near posterior margin; T 1 with strong, longitudinal striae on posterior 0.5; T 2 transverse, with anterior and posterior margins sinuate; T 2 mostly sculptured, but with smooth areas centrally and along margins; ovipositor sheath 1.0–1.1 × as long as metatibia; tegula and humeral complex brown; longitudinal strip on metasternum yellow (rarely bright yellow); pro- and mesocoxae yellow-brown to pale brown, metacoxa dark brown to black; pro- and mesofemora entirely yellow; metafemur mostly (except for anterior 0.1) and metatibia mostly (except for anterior 0.2–0.3) brown; body length: 2.10–2.58 mm; fore wing length: 2.28–2.85 mm. Among species with mostly sculptured T 2, D. scottmilleri can be distinguished by its T 1 and T 2 shape and sculpture, anteromesoscutum and propodeum sculpture; legs color and overall body appearance less shiny and less smooth than closest (i. e., similar morphologically) species; F 15 length is the main diagnostic character to separate it from D. robpringlei.
Distribution.
Costa Rica.
Biology.
Gregarious. Thyrididae: Microsca paullula.
DNA barcoding data.
BIN BOLD: AAC 2174 (41 sequences, 35 barcode compliant) and BOLD: ACE 8823 (5 sequences, 3 barcode compliant).
Etymology.
Named in honor of Dr. Scott Miller of the National Museum of Natural History of the Smithsonian Institution, Washington, D. C., USA, for his two decades of steady and enthusiastic interest in, and support of, all the GDFCF and ACG activities as a member of the Board of Directors for the Guanacaste Dry Forest Conservation Fund in its integration with Area de Conservación Guanacaste, Costa Rica.
Notes.
Specimens from this species appear in BOLD as two different BINs (BOLD: AAC 2174 and BOLD: ACE 8823) that however have identical barcodes. Morphology is also similar so they are considered to be the same species here.
