67. Prodilis guatemalana (Gorham)

Neaporia guatemalana Gorham 1897: 222 . Prodilis guatemalana: Korschefsky 1931: 109 : Blackwelder 1945: 444.

Description. Female. Length 1.9 mm, width 1.3 mm; body elongate oval, elytron with side slightly curved, wider than pronotal base, widest before middle of elytra. Dorsal surface entirely shiny. Color black ( Fig. 686 ); head black with reddish yellow clypeus ( Fig. 687 ); pronotum and elytra black with lateral border narrowly reddish yellow; antenna yellow; mouthparts yellow; legs yellow; abdomen with basal ventrite black, ventrites 2–4 dark brown medially bordered with yellow, ventrite 5 entirely reddish yellow. Head punctures small, separated by less than a diameter, nearly contiguous; pronotal punctures larger than on head, separated by a diameter or less, often nearly contiguous; elytral punctures as large as on pronotum, separated by a diameter of less, often nearly contiguous; prosternal, mesosternal punctures large, separated by less than a diameter, nearly contiguous; metasternum with large punctures along anterior and lateral borders, punctures on remaining surface small, sparse; punctures on abdominal ventrites 1–3 large, separated by a diameter or less, punctures on remaining ventrites small, separated by about a diameter. Head pubescent, frons slightly widened from vertex to clypeus, nearly twice as wide as eye measured at vertex; eye canthus short; apical maxillary palpomere long, narrowed to apex in apical ½. Pronotum widest slightly anterior to middle, reflexed lateral margin wide, widened from base to apex. Epipleuron flat, wide in basal ½, as wide as pronotal hypomeron. Prosternum slightly longer than wide, longer than mesosternum, lateral carina extended to base of prosternum; apical margin arcuate. Postcoxal line on ventrite 1 short, narrowly rounded, extended slightly beyond midpoint of ventrite. Apex of ventrite 5 arcuate medially.

Male. Unknown.

Variation. Length to 1.9 to 2.0 mm, width 1.2 to 1.4 mm. Body surface varies from black to dark brown.

Type locality. GUATEMALA: S. Geronimo (Lectotype here designated).

Type depository. BMNH.

Geographical distribution. Guatemala.

Specimens examined. 2. Lectotype labeled “S. Geronomo, Champion/ Neaporia guatemalana Gorh. (handwritten)/Type (orange bordered disc)/B.C.A., Col, VII./ LECTOTYPE Neaporia guatemelana Gorham Gordon 1970 ); Paralectotype labeled “Capetillo, Guatemala, G. C. Champion /B.C.A.. Col, VII. Neaporia guatemalana Gorh / Syntype (blue bordered disc).”

Remarks. Prodilis guatemelana is distinguished from other Prodilis species by dorsal surface densely punctured, punctures contiguous or at least partly so throughout, an elongate oval body, and uniformly dark surface. In addition to the type specimens, one other female specimen in the BMNH is placed with them but not considered the same species.
