Etymology. This new species is cordially dedicated to Milton Norman Medina from Davao Oriental State University, Davao, Philippines, an active researcher on the tiger beetles of the Philippines and a friend.

Diagnosis. Prothyma (Genoprothyma) miltonmedinai is most similar to P. confluenteangustata ; the two species can be distinguished by: 1, the shape of the aedeagus: in P. confluenteangustata the apical part of aedeagus is slightly downturned and apex short, while in P. miltonmedinai the apex of the aedeagus is long and strongly downturned.

Description. Size: TL (without labrum) 11.9–13.0 mm (mean = 12.3 mm, n = 6).

Head: Color shining black; with coppery-red reflections on orbital plates, near pronotum, and basal part of genae; with bluish or greenish reflections on apical half of genae; with two greenish or violet areas near basal half of orbital plates; clypeus greenish or bluish; surface glabrous, with two setigerous punctures next to eye, one along frontal margin and one dorsally at center; longitudinal striae on orbital plates and vertex; strong transversal striae behind the eyes and on neck; genae, frons and clypeus weakly striate. Head as wide as elytra (mean EW/HW = 1.0). Labrum bicolored, ochre-testaceous, margins brownish, black area basomedially, bilobed or extended to the apex in some specimens. Labrum of male ( Fig. 13c ) wider than long (mean LW/LL = 1.4); with four setae located near the margin, two lateral and two apical; with two blunt anterolateral teeth and two outward directed thorn-like anterior teeth at the anteromedian lobe, intermediate space with a triangular tooth. Labrum of female ( Fig. 13d ) slightly wider than long (mean LW/LL = 1.1), with four setae located near the margin, two lateral and two apical; with two blunt anterolateral teeth and two outward directed thorn-like anterior teeth at the anteromedian lobe, intermediate space with a large triangular tooth. Mandibles brownish, with four teeth, margins darker, small area of base ochre-testaceous. Labial and maxillary palpi testaceous, the last segment shiny black. Antennae slender, reaching posteriorly to the middle of the elytra in males, shorter in females; scape and antennomere two black with metallic luster; antennomeres three and four black with metallic luster and with brownish part at the apex in some specimens; scape with one apical seta, the following three antennomeres almost glabrous; antennomeres five to eleven black, dull, finely, and evenly pubescent.

Thorax: Pronotum as long as wide (mean PW/PL = 1.0); sides slightly rounded between the transversal constrictions; glabrous, with transverse striae on disc; shiny black with coppery-red reflections dorsally; transversal constrictions with bluish-green or violet reflections; margins bluish-green; sternae and episternae glabrous, shiny black; mesepisternum of females longitudinally grooved in the middle.

Elytra: Twice as long as wide (mean EL/EW = 2.0), parallel-sided, with a slightly flattened basal hump, dorsal surface shining coppery-red, violet along the margin and bluish-green at its humeral part; elytral testaceous maculation consists of a humeral dot, absent in female specimens, a lateromedial dot in the form of an oblique backwards band, narrowing towards the tip or nearly separated into two patches, and an oblique preapical dot; surface with dense and evenly spaced punctures, becoming confluent and forming flattened grooves along the suture;; apical margin gently rounded, with a tiny sutural spine. Epipleurae black.

Ventral aspect: Venter glabrous, bluish violet; trochanter glabrous, coxa, femur, tibia, and tarsi setose; trochanter, coxa, basiventral half of femur testaceous, remainder of legs blackish with metallic luster. Protarsomeres 1–3 in males laterally and ventrally covered by long white setae.

Aedeagus: ( Fig. 13e, f ) in lateral view, slender in the basal third, then expanded and tapering again towards the apex and elongated to the ape, strongly curved with tip angled and thickened (total length 3.2 mm). Endophallus in basal part with two groups of spines.

Distribution. MARINDUQUE —Boac, Buenavista.
